383 LT1 Tuning Problems
I've got a 95 z28 with a built 383 stroker. I've already sent my PCM off to be flashed for the motor. I got it back and it runs, but it's rich as hell and the timing is off. I've got a couple friends with tuning software like hptuners, but those only work for OBDII computers and I've got OBDI. I was looking at TunerCat's OBDI LT1 Pro Tuning Kit so I can just do it myself, but I don't know anything about them. What do ya'll think I should do?

We use it on a lot of the older stuff, and it works great. Customer service is great but no-one is going to tell you how to tune it over the phone though. You will have to do a lot of reading and try it yourself. Not a lot of people like tuning the older LT1s.
If you have any mechanical issues with the car it can compound the learning curve very quick.

I realized that nobody likes tuning the older LT1s too... Do you know how user friendly the interface is? And will I be able to program more than 1 pcm with it?

Oh, I understand that. I'll make sure to send you an email. Will I be able keep it plugged up while I'm driving so I can tune it more accurately?

it does exactly what you tell it to do lol you just have to know what your trying to tell it... and it's very easy to mess something up. Whatever you do make sure and save a stock tune to always go back to if you've went to far...

Yea, I think that's going to be the fun part... Trying to figure out exactly how to tell it what I want it to do. I'm gonna save the original in a couple places, can't lose that...

Get TC, its very affordable. TC for the OBD1 is still able to tune as many cars as you want afaik. I converted my 97 to OBD1.
As stated whatever you do, save all your tunes when you make changes. That way you can always re-flash with a prior tune if you dont like the changes you made.
Basically all you have access to with the software are look up tables. I havn't used any OBD2 stuff but it's most likely the same deal so have your experienced friends help you out as well.
I data log with freescan, it's free.

So if I get the TC pro and then wire a cheap one up, I'll be fine... If I don't want to get TC then I need to get one of the expensive widebands that comes with it's own control box...
