evo 9 MR JDM

**** CLOSED ****
FIXED THE PROBLEM
THANKS



Guys, need help...

Just Replaced the cam with M2 Cosworth Mivec Cam
and change the injector with PE 680
and doing EcuFlash by my self

I put Injector scaling on 570 & latency already been tuned to gain +/- 5% STFT reading in EvoScan

Now the car won't idle on 800 rpm, it needs 930-950 rpm to idle,
at 930 RPM the idle is better but still, a little bit rough
and I think the 950-ish idle is too high

anything is wrong ?

a friend told me to richen AFR to around 13.5 on idle
the problem is ,car still run 14.7 (on LC1 wideband) after i put 13,5 AFR in both High octane & Low octane Map in 500-1000 rpm, area under 10-30% Load...
so No Result...

Read on the forum that rubber turbo inlet pipe will cure rough idle, BUT after, change the turbo Stainless inlet pipe with the OEM rubber one, still rough iddle

any idea what should I do next ?

Thanks

Read your other thread. If that doesn't work, you need to continue to tune your injectors.
