I have been slaving away on my 88 GT to get it back on the road. I have been having troubles getting the 7730 ecm to work with this setup I have in the fiero now.

I have a 3.4 pr. with a 272 cam in it and can't seem to get it running and at this point i believe that it is the tuning on the ecm.

I have a basic $88 tune and I do have DIS setup on it as well and was wondering if anyone has done such a swap and has the ecm working with this setup.

Thanks!

Most people with DIS run the $A1 ...also someone has improved the A1 on another forum.... Perhaps you should download the one for the 3.1 MPFI motor and go from there...

Does the engine run if you spray carb-cleaner into the intake?

$88 is for a distributor.

A1 is DIS

I am running a similar setup, 3.4 p/r, 260 cam, dis on an $88 code mask tuned by sinister and it runs great. Took about 11 tries to get it right tho.

I have a 3.4 with a 7730 and DIS. I also had Sinister tune mine using $88. You may have to start at the basics and double check your wiring especially wires that are critical for the car to start. Also make sure you are using a knock sensor from the ECM's donor car. You can also check the knock sensor wiring.

I have been talking to Sinister about this and figured I should ask around first and see if anyone is a couple more steps ahead on the tuning.

He did say he was willing to do it and since a lot of people have had good luck with him. I should as well try it too.

Would you JCircs might have the tune before the turbo when it was running well?

I really appreciate the comment as well on this subject.

As I was searching through my email archives I realized I didn't add the 7730 till after the turbo. I did locate bin files but there all for the 3.4, 272 cam, dis, with turbo.

Did you JCircs know which masking code you used? the $A1 or $88?
