No more idle
EDIT : problem solve, it was a boost leak, you can close this topic
Hi, I just turboed my 1990's miata
the set up is T25, 2.5" inch straigth pipe exhaust,
I run with stock ecu, stock injectors, Narrow band O2 sensor and MAF
I do have an intercooler but don't have a BOV, I need to go get a pipe that will fit with my recirc valve....
I was suppose to have 460cc injectors, 190 lph hp walbro fuel pump and LC-1 WBO2 but the megasquirt was'nt ready
so I'm running under 0 psi, I don't boost to avoid detonation until my management is done
When we first start it, I wasnt possible to reach a stabler idle, so we caped the IAC and adjust the IDLE screw, everything work fin for 2 days (saturday, sunday and this morning) (50 miles of highway and city)
but this morning when I took the exit ramp of my exit to go to work, I put it in neutral and the engine stalled, So I had to brake with my left foot while keeping a the engine at 1500 rpm with my right foot at the 3 stop I had to do.
I first try to completly unscrew the IDLE screw to compensate but it happens to be worst. (start the engine, rpm peak at 2500 rpm 2 seconds then stalled)
I screw it back, start the engine, rpm peak at 1000 rpm, 4 seconds then stalled)
My body told me to make a tiny hole in the cap, so the leak might compensate what's missing....
Hope you guys might help me!
