i have a JDM D15B with a complete greddy 15G setup... with a kenji p06 ecu with vtec conversion programmed for my 550'z.... ok, i removed the FMU once i installed the injectors and ecu... now my idol is all weird... it jumps up n down from 800 - 1300 RPMs... what can i do to fix this ?? would a missing link have anything to do with this ?? or my check valve ?? before i installed the injectors, it was previously on a p28 with fmu on stock injectors, and it idol'd fine... any help would be much appreciated...

 

i dont know if youve ever seen the omniman b16 dvd but when he was dyno tuning his car it loaped relly bad up and down like 800 to 1300 or so just like yours is and it was because the car was running a little bit to lean and when he corrected and added fuel it imedietly ran perfect. just a thought.

Good Luck

 

^^ thanks for the info.... more info would help... running a bit lean is the last thing i would think my setup is doing

 

your iac might just be going through relearning process drive like 10 miles and shut car off then restart withouyt disc. batt might go away

 

i'll try that, just removed my missing link and its still boucin up n down

 

help meeee
