Haltech wiring

[Blakvsexec]

Hi all,

I have just read on another forum that it might be possible to wire in a haltech E6GMX as a piggy back ecu for my Auto vs v8 commodore.

Has anyone done this or heard of anyone doing this, it would save me lots of money and time if i can.

Cheers for any answers

[dirt drifter]

yes it can be done, and has been done many times. its basically keeping the stock ecu to control the transmision only, and running the engine wires into the haltech instead of the stock ecu.

with any luck u can find a auto sparkie who can do it easy, if ur good with a soldering iron and can read a wiring diagram u could do most of it yourself

[sircruisealotVS]

It can be done...by why would you??The factory delco is a much better ecu than a cheap ass haltec.
Keep your standard ecu and save yourself the waste of money.
If you are going to go ahead with it, be prepared to have constant fault codes being logged (engine light on) and the auto not shifting where you want it to, and not having any ability to modify the auto shift points and pressure like you could if you just got the standard delco tuned with kalmaker software.

I keep hearing " get your stock ecu tuned with kalmaker"
That would be a fair idea if i lived in nsw or vic, as it seems the only places where anyone uses kalmaker, there is no one anywhere near me that can tune with kalmaker let alone even heard of it.

I would use the stock ecu if someone this side of tha black stump could tune it for me, but there isn't so i am just stuck with having no choice other than run something aftermarket that i cam get tuned here locally without having to drive to the other side of the bloody country.


RANT OFF.

theres a few well respected engine builders/tuners out there who recommend the haltech or equivalent over the stock ecu. because of the ease with which they can alter the tune (kalmaker takes a while apparently) and the features they have that would be wicked if u ever went blown or turbo (antilag, variable boost etc)

yeah the stock ecu has better cold start, and diagnostic mode etc. but a properly tuned haltech shouldn't be too bad of a thing

[Blakvsexec]

I agree, The Haltech i am looking at is the sprint 500 wich can be run as a stand alone aswell as a piggyback.
This is the ecu that has been reccommended to me by 4 different tuners.

[delcowizzid]

the last person i knew who had the sprint 500 fitted as a piggyback is still waiting to get his car back from the shop it just wont run right exhausts glowing red no power after 3500rpm tuner has blamed his bcm after it fried when they wired the haltec in and windows locking etc stopped working.replaced that then still wouldnt run properly $10000 forged turbo v6 engine being run in glowing red hot he aint happy

[Blakvsexec]

I am currently looking at a setup running a delco 808 from a vn vp as a piggy back to run fuel and ignition. Have another guy helpin me out with the setup and the comms board and the new memcal replacement board for the 808.

Hopefully i can find a tuner who will be able to tune this setup as it will cost me bugger all to put together and i'll retain the stock ecu.

[delcowizzid]

you can buy the same deal to fit in the auto ecu and run the whole lot just as factory as it is now no cutting wires no piggybacking

[delcowizzid]

or do as i normally do and fit a vr auto ecu and go map instead of maf

[Blakvsexec]

delcowizzid I have a series 1 vs which has a map sensor not the MAF, What program are you using to tune the stock pcm ???

[delcowizzid]

doh sorry forgot you are v8 not v6 LOL the same 808 realtime board will fit into your ecu and with the right tune will be able to be tuned realtime with tunerpro R/T theres a connection cable to plug straight into your aldl socket under the stearing colomn so you can tune straight up that delcohacking.net • View topic - FS: USB Vehicle Data Interface and the rt board delcohacking.net • View topic - FS: NVRAM ECM Conversion vl400 has factory tunes all modded for tuning live

[Blakvsexec]

Ok so where do i get a copy of tunerpro R/T from?
Will i have to supply the laptop with tunerpro on it for the tuner to tune or should he have it ?
Will he be able to tune with it if he has never used it before?

So if i get the usb vehicle data interface and the nvram ecm conversion board, install it myself will i have to load the tune from vl400 to get it to run enough to get it to the dyno?

Is there anywhere i can read up on tunerpro to work out where to adjust settings for larger injectors etc just so i can get the thing to run good enough to drive to the dyno.

As for the tuning would I ( someone who has never tuned an efi car) be able to tune it myself or just put the base tune on it and let someone who knows what they are doing to do it for me and hopefully not grenade the donk.

I ask these questions because i have never played with vehicle control electronics before, i just dont wanna fudge things up.

All your help is greatly appreciated.

[Blakvsexec]

Ok i have tunerpro R/T and contacted vl400 about the recommended hardware and tune.

[delcowizzid]

theres a getting started guide in vl400's signature on dh.net just changeing the injector size to get it running to get to a dyno is easy done .a tuner who hasnt used tunerpro or played with delco ecu's will have a bit of learning to do compared to a haltech the delco nearly has more settings just for idle than all the haltech

[Blakvsexec]

ok so it sounds like i need to try and find a tuner who has used tunerpro before then.

[Blakvsexec]

Well i am back to square one again, no one in my area can use tunerpro and most have not tven heard of it.
So i guess i'll just try an pick up a stand alone ecu and just piggy back it to run the fuel and ignition only and let the factory delco run the rest of the car.

If anyone has a stand alone ecu that will run a v8, and you wanna get rid of it let me know. I'd prefer a haltech but will consider anything.

Cheers for your help and patience delcowizzid.

You could have a crack at doing the tune yourself.Theres plenty of info about to learn from.Delcohacking website is an excellent one.Ive just done my first chip in my VS V6,Im very happy with the results for a first attempt.It all seemed a bit daunting at first,I didnt think Id be able to understand it all,but its not really that bad once you have had a good look into it all,and have had a bit of a play around with tunerpro.

[Blakvsexec]

I would have a go at it myself but my car is my daily drive and i rely on it to get me to work and back reliably, So i need to have it tuned properly as soon as i have the supercharger all bolted up and ready to go.
I cant afford to be rebuilding engines because i got the tune wrong and had massive detonation under boost and have it lean out and grenade the engine.

I usually will have a go at anything and delight in doing things that others tell me i cant possibly do myself, but on this occasion i just cant risk it.

[delcowizzid]

your probably better off setting the box up full manual with no ecu control and going full haltech ecu for engine then cause with boost youll want to tweak the auto settings from stock and if you dont have a tuner for the delco then the settings are all of no use

[Blakvsexec]

Can i adjust the gearbox settings by using tuner pro?
Would i need to use the nvram conversion to do this or not?

I will play with the transmission settings myself just not the engine.

I have a transgo shift kit and some other bits and pieces destined for the gearbox sitting on the shelf here too.

where abouts are you? sorry you dont have a location in your profile.

[Blakvsexec]

Gladstone, central queensland

So going by your sig you have a stock VS V8 with exhaust done and a GreenFoam tune, are you planning other stuff, what more do you want from a stock setup? Sorry if this is not correct.

[Blakvsexec]

I have this going on (the manifold is not finnished yet.)


And one of these(ls1 throttle body)


And these(36lbers)


Plus a small cam that will make full use of the supercharger.
And the usual other mods, extractors, twin 2.5" exhaust, bigger fuel pump and everything else you would upgrade for such a modification

So hence the need to upgrade the ecu so my tuner can make it run properly and not detonate the engine.
