Hey everyone...

I recently bought and installed a Used ECU upgrade.
Its set for 1.06 bar primary and 1.0 secondary.
THe previous owner said its tuned for
Intake, CB, DP , MP and Intercooler..
I have everything Except the MIDPIPE.

I realize that the car would run rich because
i don't have a Midpipe.. Which leads to my question.

The ECU works great. getting good boost and etc.
BUT !@?!@!?@?!@?!@?!@

When the car gets HOT, and the Fans kick on..
IT makes my car IDLE bounce from 2k-2.5k..
UNTIL the Fans KICKS OFF.....

WHY IS IT DOING THAT?? is it because its to RICH??
because i don't have a Midpipe??

Is it suppose to do that??? Does reving the motor when the cars fan kick in make it cool better???

Is there anything I can do to fix or diagnose the problem?? Anyone have similar experience???

OR should I not trust the ECU ??

Other than the IDLE flux when fan kicks in. IT works
FINE....

Thanks..

 

Oh by the way...
I already resetted the ECU.

the problem went away for a minute.
but came back..

 

Sounds like a mis-adjusted TPS. Do a search for instructions on how to adjust.
