I got haltech ECU with me since 3 weeks. I was waiting a detailed thread from trusted dealer to review it, But all was waiting for something we don't know.


So i went to Garage in Dubai (Bin Silyiam Performance) who i used to deal with since 1995, and who is know world wide of his SLK with SLR engine, Anyways.

I asked his engineer Robert to install it and tune it for me with installing 800cc injectors i got from AAM. He asked to give him a week to gather info on the ECU, so he contacted Australia and some

japans friend. to say to him STAY AWAY FROM IT..FOR NOW??!!!!

Yes, they told him it got many bugs and errors, it already killed 2 engines ( other than Haltech them self), the ECU is harming the engine, even he called Motec , and as he is a dealer with them , they told

him that they got Haltech installed on GT-R to test and see what they made, and found it danger on the engine. They have said, "The way Haltech made this ECU and how it control the engine is a

dangers way and could harm the engine."

So his word is, keep it until Haltech fix the problem in it.

Ok, this wasn't shocking as we already seen some will known venders here saying the same thing"Waiting Haltech to fix some major issues??!!".

So what am going to do, Nothing, keep Haltech until some updates happen.

Also for now, am contacting Mines back to see if i can get custom tune with 800cc upgrade, until i see what SPE get from greddy kit.




UPDATE:

I had no other way but to install the Haltech. winter here and fun time started. Knock had to disappear, But Mines will not help in custom tune for my mods list. So i installed 800cc injectors and HKS fuel regulator.

The tune and installation was done by a friend. So what my comment on it? NOTE: boost was not changed from last Mines tune.

The car feels or lets say kicks you hard. I never made my ride spine 4wd from 1st gear through 2nd. I never heard my tires scream of pain :P

The acceleration through gears is as furies as 2nd gear.

Cons:

It sometimes hesitate to startup. also sine Haltech does not control throttle, it bounce at low speed( this happened 2 times for 2day now).


Update:



FAST update,

I have changed ECU with new harness. Now it runs as stock. I really can't feel it as i used to.


Haltech is working hard on it. Keep the good work.


Still waiting my greddy kit. hope to receive it as promised early DEC.

More times than not when something like this happens with electronic equipment, it usually never gets properly fixed, and you're stuck with a useless box. Hopefully, your dealer will either let you get your money back, or promise when/if this ever gets fixed, will let you exchange it for a new/updated one.

I'd get my money back as soon as possible and maybe re-buy it once it has been proven to work. Right now, it's a worthless box - probably just sitting in your garage losing more and more value every day.

So your friend in dubai who is a motec dealer, called motec to ask what they thought of Haltech's GTR ECU hey - now im no genius but im thinking they might have a biased opinion. Given that Haltech is now a major competitor with Motec and Haltech is releasing ECUs for cars motec cannot run yet id understand why Motec would say anything to discredit a Haltech ECU.
A number of GTR engines have been damaged over the past 12 months (not just Haltech powered vehicles), each of the engines that had Haltech ECUs were putting out much more power than stock without internal modification - talk to anyone who has seen inside the GTR engine and they will tell you its NOT built strong enough from factory to handle much more power, the standard pistons are cast not forged, the block is plasma coated not nikasil coated so engines producing above about 600hp are in troubled territory:

http://www.nagtroc.org/forums/lofiversion/...php/t22403.html

While its no secret that Haltech has had some production problems, these problems are NOT related to how the ECU runs the engine and they are NOT related to any of the engine blow ups that have occurred. Talk to Haltech and see, the problems they have been having are from pins in their patch harness getting clogged with the OEM waterproofing material and causing random CEL lights and transmission slip problems at high horsepower due to line pressure. The Trans issue has been fixed with a code update to increase line pressure and new harnesses are being manufactured with a different waterproofing - how do i know this, i asked Haltech (not their competitors !).

Well, First of all, My he is not my friend, it's a garage i deal with and trust on his work, They done my 4X4 landcrusier which did 752 4WHP. That i used since 2003 until i sold it last year. No problems. BTW, it used Autronic ECU.

The garage is dealer for Motec, Autronic and some other ones that i don't remember.

So, he didn't call "Motec" to ask about Haltech, as i said he called Australian garages and a Japanese dealer, to get info on the product before he tune mine.

But later he contacted Motec to see if any planes for GT-R and they as competitor will for sure know Haltech ECU and what i can do.

Over all, not me or my "Friend" said they is some issues in them. And am not returning it due to this info.

Am keeping it until i get green light to go and updates get done.

OK well that makes more sense then - from the way i read it i thought your "friend" called Motec to find out how a good a Haltech ECU was ! I have talked to a couple of the workshops who have actually tuned the Haltech ECU on GTRs and they are all very happy with the ECU and what it can do, the only reported problems are the CEL and slip problems that Haltech is working on. Thats what i hear from Haltech directly.

The big problem for Haltech is that the nissan engine just isnt up to the horsepower levels that the Haltech ECU can release - once people have worked this out and replace pistons and sleeve blocks (or replace the plasma lining with nikasil lining?) im sure we will be back to talking about breaking gearboxes and diffs, then something else will break....it will be a few years before the path to reliable high horsepower GTRs has been fully paved.

if i were you, i wouldve gone with the AMS turbo setup with sharif's tune.

Wayed ista3yalt bro. <--- ( for those who dont understand, this is Arab'lish ).

unless your going to be changing the bottom end and stuff, id stick with what u got, but then again, like the above poster stated, you will face problems in different areas too.

It's a good ecu but it was released too early.

Just sit on for a few months and wait for the updates they are working on.
Are you using this update?
http://www.haltech.com.au/index.php?option...1&Itemid=32

don know what to say but,
I have tuned 8 cars for my friends, two of them 1000 CC injector bigger turbos and the others 800cc running full throttle 24/7 for about 2 month with no problem except slipping issue which haltech is in process to get sort it out which is not related to the engine,
no buges no errors.

Bro,

Keep updating me on it, if you got any updates and when you see all problem solved.

What cars did you tune?

GT-R

NO issues with Haltech in the GTR? Wow...

r4race why dont u tell them about your race with the buggati ;)

lets see some video

I would like to chime in here. I know of 1 other motor that has blown up from a haltech, and the issue was not the ECU in any way shape or form. He will be doing a big write up on the blow up and it will be posted soon if not already. Basically stock turbos at high boost levels and high power levels are all fine and dandy for 1/4 mile pulls and quick hard accelerations, but they generate very hot air at high boost levels. Stock intercoolers should definitely be replaced if you plan on running say more then 15psi for long durations... His car logged i believe like 6000 miles (on track time) as well as was over 30,000 on the motor from being modded since early in its life. The problem he had was the piston (ii believe # 6) melted. It like shrunk up from excessive heat.. no detonation, no ecu issues, just extreme temps generated from high boost levels on a track going 3-4-5 5-4-3 3-4-5 kind of driving consistantly and it finally gave way. I have the haltech on my car, running 600whp / 600 trq and its been on there for about 3000 miles.. strong so far, and yes it has its issues and annoyances but it was mainly the tranny going into limp mode at random times, which seems to have been worked out, i just received the modified updated harness i will be putting on my car. The new firmware is right around the corner which is supposed to eliminate ECU codes and what not, i believe the Knock prevention is close as well. Anyways, there has been a few motors blown up from what i know, some on COBB tunes and some on Haltech... So no matter what way you go, motors are going to blow, people are testing the limits and pushing there cars, things are going to happen... anyways hope this helps a bit.



Mark

shooooooooo?? wat race? tell us!

+1 or it never happened.

New haltech harness v2, and firmware update right around the corner

Just been told that Haltech is recalling the ECU, i will be checking with them tomorrow about it.

wow thats news to me?

Did your motec dealing workshop friend tell you that too?

Why would haltech produce a V2 harness and continue to develop firmware and fixes if they were going to recall the ECU? Doesnt make sense to me to recall at this point, last i heard was Haltech is sending a couple engineers to CA to look at the high HP slip problems and anything else that may crop up....doesnt sound like the actions of a company about to recall this ECU !

Yea i spoke to some people and the ecu is not being recalled. They are sending out V2 harnesses to anyone who has the v1 harness with a free return label to cover shipping back.. I installed it.. took about 25 minutes.. its just annoying to get to more then hard to do. Haltech has been nothing but great with customer service and tech support on this system and thats the only reason i have kept my cool and worked with them on resolving issues..

The slipping clutches i figured out. Its basically the car throwing a code for cam advance ignition timing bank 1 i believe.. or cam bank 1 .. i cant remember exactly what it was, but when the stock ecu Noticed something with the cam timing adjustments out of range it was throwing a code and that was putting the TCU into a limp mode where at 3000 rpms it would pull the clutches back. You clear the code with an OBD-II reader and your car was fine again...

My car did it twice, in about 1000 miles... and hasn't done it now in almost 3000 since i got this modified map and what not. They didn't change my timing but they did do some changes to resolve the issue. I was told firmware is not far off, which should have Knock Control and eliminate the Check Engine codes for things such as O2 sensors and what not.



Mark

As i said, i called Haltech to confirm if any recall happened.

There was no recall on the ECU, but infact it was the harness that got changed due to silkon isolation defect.

But, are they recalling it from all? Nope. the tech said, "If you got some errors and problem while tuning contact us to send you new harness". Ofcoures i said that error maybe effect my car while tuning to figure it later.


BTW, matt510.

The tech guy from haltech is my freind too.

yes i believe its for the Cam advance engine code that puts the tranny into limp / safe mode. Thats the recall.. i've known i believe 3 cars total its happened to. Other then that, you should be fine, but yes the silicon was causing pins to have connection problems. i know a few people with V1 harnesses that are fine. For anyone looking to put Haltech in there car i would wait til 1.0.6 to come out and not put in 1.0.5. Like i said it should be a week or 2 at most.

Indeed, i can't figure if my harness is V2 as no sticker on it. Could it be V1 as V2 will be stickered?

yea i posted up a pic of mine.. the V1 had no sticker v2 did.

Wow

Yes please wana see some video.
What is your 60-130mile or 100-200km?

only new video i have of my car.. this is at 16psi.. is this.

http://www.youtube.com/watch?v=aRqKwCsZquU

thats like 15-130

aaah I wish that my GTR was there

:-(

Is the Haltech still totally failing to incorporate Knock Sensing with Ignition/Fuel adjustments to save engine if knock comes?
Who was hawking this before, saying knock sensors are stupid and useless and The Perfect Tune He'd Make would never knock? (LOL)

yes, i was told they resolved the issue of the slipping clutches and incorperated it into the new firmware which is being tested on a few cars as we speak, from what im told is this week i should receive the update.

Includes removal of the o2 codes, and the knock control, as well as the fix for the clutches... and possibly a few other things.

UPDATE:

I had no other way but to install the Haltech. winter here and fun time started. Knock had to disappear, But Mines will not help in custom tune for my mods list. So i installed 800cc injectors and HKS fuel regulator.

The tune and installation was done by a friend. So what my comment on it? NOTE: boost was not changed from last Mines tune.

The car feels or lets say kicks you hard. I never made my ride spine 4wd from 1st gear through 2nd. I never heard my tires scream of pain :P

The acceleration through gears is as furies as 2nd gear.

Cons:

It sometimes hesitate to startup. also sine Haltech does not control throttle, it bounce at low speed( this happened 2 times for 2day now).

With the big injectors, my startup in the cold weather is a little rough occasionally.. but that is 100% a tuning issue. The latest haltech software feels great. Not sure what u mean the bounce at low speed???? I dont think i have that problem, but not fully understanding what you mean. Haltech definitely doesnt control the throttle... YET.. Kind of sux but will be a good thing when they lock that whole thing down.

By saying bounce. i mean while at 40mile steady drive. the RPM (EXP)2000 it drops to 1700, then back 2000rpm. this only happen while driving slow at steady speed. But, when i engaged the cross control it was fine.

o i had an issue like that which i think we tuned out as well... like 30% throttle on a cruise the car felt like it had a surge where it would be like i was pumping the gas really fast.. . haven't had that in months now tho.

Is this the 1.06 beta version you guys are using?

The Haltech site is only showing the V1.05.0 and i know that firmware is not utilizing knock control etc.
How long do the JDM cars have to wait to get the new firmware?

I think that software should be released fairly soon. I know they just had a few people testing it, SPE being a main customer that had it for their Greddy setup. Not sure on a definite date but i cant see it being that far out for everyone.

Nice to hear that bro

I hope you are enjoying your ride

mine is 1.06.





Thanks bro, you did a great job in tuning the haltech. ^^^^^ my man.

im glad everything has been sorted out for you. Now, enjoy your beast in good health buddy

Indeed, until the greddy kit arrive.

Did you get a date of when youre receiving your kit?

Nope, all was said is the 3 kits is ready , maybe in 2 weeks.

+1 on the Haltech. Been running over 1000 miles like a champ, running on custom SPE mapping. Power over Cobb unit is night and day. There is so much limitation on the COBB that I don't even want to start, but it's a good unit for starters.

Wayne
Phase 2

^ Good news! I think this is going in the second my warranty no longer works.

if it hesitates a little on start up and also rpm bounes up and down at lowspeed i would get your tuner to check the injector lag time and post start enrichment tables also.

UPDATE,


yesterday, After testing my ride with friend 350Z in low boost and high boost, which resulted nick to nick on both, But, had the advantage in fast gear changes.

Anyways, after the runs, which we did 6 times. i drove on auto and N N N mod, suddenly at 4th Gear, after i increased my acceleration to pass a car, the tranny went to free, it seemed clutch slip, but it wasn't, i got tranny light on dash and slowed down.


Drove it back to 4th again and didn't happen. Seems it's same problem that happened before beta firmware.

Did anyone get same issuse?.
