first of all happy new year and now for the bad part i have a 1984 gn converted to intercooled last nite i hit the gas hard and the car blog and made a loud popping noise it sound like its coming from the intercooler and the the car will put up speed if ease into it but if i try to just hit it its like the thottle will not respond and one more thing alky is not working i hit the test buttom both light come on but when drive will not activate:

The Alky problem may be as simple as the vacuum line leaking or broken from the 3 bar MAP sensor. The popping may be trickier to find. Some of the possible causes are a bad MAF sensor, bad coil pak/module, and bad spark plug wires. Check these first. Keep us posted. Brad

HEY DID U EVER GET THIS PROBLEM FIXED I TOO HAVE THIS PROBLEM :/

I had that same problem when I first converted and found that the IAC was not set according to Eric's ( Turbo Tweak) recoemendation. It would sputter and pop if I layed into it . If I eased into it it did fine... you may want to check that . I had to get a scan master to dial everything in and adjust air /fuel ratio

Dmac so now your all good?... I have yet to get a scan master

 

[DMAC]

Yes I am good now it was very frustrating to find out ,, I could drive the car normal without any issues but once attempted to accelerate fast it would studder ( felt like it wasnt getting enough fuel) and at times pop ( backfire) ......I was chasing the wind until I was able to check off my readings on the scanmaster asap

Did you get another chip when you converted to IC?

 

[PATINO]

I have no clue what chip is in it I just got the car like two weeks ago n well I didn't notice this problem since u kinda just been driving it around normal until the other day when I was on highway n there wasn't traffic

 

[PATINO]

What was the problem after all?

Did you convert car to IC after purchasing the car? or was it already done?

Do you know if it has the 86/87 ECM in the car or Hotair ECM?

Yes the car pulls like a freight train now . I am up to 28lbs of boost on E85 with no knock still !!


Now I just need a good radar detector !

 

[PATINO]

It was already turned into intercooled when I got it and yea the ECM is 86/87

 

[DMAC]

That is good news the ecu and been upgraded, I would recommend you get a scanmaster , My car only did that when I floored it which sounds like your issue.

 

[PATINO]

Yes it does only happen when I floor it.... What ended up being ur actual problem though??.... As for the scanmaster I'm planning on getting one ASAP

 

[DMAC]

On my car the TPS was not set to the recommended .42 Once I reset that it was like driving a different car print off the two attachements that I uploaded into the thread and follow those to make sure your TPS is set correctly . It is hard to beleive that something simple at times can cause so much issue

 

[PATINO]

Thanks i will download them n check them out for sure but the thing is i had my tps set at the 42 by another forum member here but it still does it

 

[DMAC]

I am assuming the fuel pump is hot wired yes?

After I adjusted the TPS I then adjusted the Fuel/air ratio using the spec sheet from turbo tweak But will you will need a scan master to make those adjustments

 

[PATINO]

it is .....ah so im guessing i will probably need to do the same thing....thnks for all the info so far man

 

[DMAC]

Not sure but having a scanmaster will tell you alot about what your car is doing ,
