Tuning a Haltech E6A

[SappySE107]

The question is whether the 3.4 DOHC uses the same wave form output for crank triggers as the 3.1L and 3100s.

I'm sure you know what crank is in the DOHC and whether the timing disc is the same as the 2.8/3.1 engines.

next time you have a thought, think about it a bit more before you post it on this forum. You are pissing me off this this nonsense bullshit ideas you have about everything anyone does on this site.

Guys, this is Curtis Walker's old car. The "TurboZ". He has the base tune that Curtis set up for the gen 2 turbo 3.1 that he installed before it was sold.


It'll just need some tweaking since you have one already set up for a similar engine. Some constants may need to be changed but someone familiar with the Haltech would be able to guide you on those. I might still have Curtis's contact information, he may be able to guide you as well.

well shit, that makes this a piece of cake then:P I have curtis' vids and some file along with his E6A program that doesn't work on my computer. Amazing how that works when all the information is shared.

Here's my recommendation. Get Haltech to send you the manuals for the ECM that's currently in the car, spend a few hours/days reading and trying to understand them. Read a book or two on tuning. You've got a standalone and an odd platform. You'll find few shops willing to touch it for a reasonable amount of money (in your eyes) and many that would be willing to help won't know anything about any of it. The more you can learn and do yourself, the better off you will be. Tuning isn't hard or some secret black art. It just takes a bit of understanding about how an engine works, how the computer works, and a bit of hardware.

If you're going to have someone else tune it, you either need to find a shop with a lot of GM V6 experience (very rare) or a shop that does a lot of Haltech work (not so rare).

One last bit of advice. If your Haltech is so old that it's tuned by DOS and a Serial port, you may want to upgrade to one that will work with Windows and USB. It's getting harder every year to find solutions for serial ports and DOS. This isn't mandatory, but will make tuning it much easier.

If it is an E6A, here's a 15 year old manual for it.

Looks like the original and current tuning programs are DOS based.

Dell D610's make good tuning laptops if you need one. They're dirt cheap, reasonably fast, have a built in serial port, and have a great display. Unfortunately, I'm not sure if they will still run Windows 95/98/NT so that you can run DOS.

D610's will run the old OS's just fine. I have several at work, one has 2K an done has 98 and the others run XP.


XP's DOS mode should work for the Haltech.

[SappySE107]

my E6K software worked so I was able to look at it in XP. With the base file already done, this really won't be hard to tune for someone with experience. Read the manuals and use offline mode to look at the "tables". Its bar graphs that you raise and lower mostly.

I would think tuning cost depends on the shop and how much fine tuning they do. If the shop dyno rate is $50/hour you are buying 40 hours of their time.

I'd ask for an itemized estimate.

What strikes me as odd is that the shop already knows how to tune one (from previous customers) so it should save them time and you money.

That is wierd...

Thank you all for your input. I'm just a bit gun shy because I have never tuned a car before. I thank you for encouraging me to just do it and not be intimidated by the secret black art of tuning a car. I did get in touch with Curtis and he gave me a few pointers. I can not wait to start this process. I will post pictures of the build as soon as we begin. Thank you all very much! I may restart this thread on the day we start tuning. Brett
