Trying to get the new motor running.. 2.0L > 2.3L with speed density
Hey Guys,
My question is this: Is SD RPM VE table the appropriate place to adjust for displacement?
Background:
I had my car running great on speed density with stock injectors, stock longblock, stock turbo, etc.
I pulled motor and built it.. 2.3L, kelford 272 cams, +1mm valves, FP Black.. (that's all that should effect idle for now)
Now, I intentionally left the stock injectors in it for now, just so I could start it up and get a few miles on the motor.
It did start up ok for me last night, but it would not idle - I had to hold the gas to get it to stay running. I let it get to operating temp and then changed the oil.
I'm sure it doesn't idle because VE has changed and everything. Here's my question.. Where should I make changes in order to compensate for the changes? My thought was to modify the SD RPM VE table. I found the following equation to calculate airflow: Airflow (CFM) = PR[RPM*V.E.*Cid/3456. Since my displacement changed from ~122CI to ~140CI, I thought perhaps I could multiply my SD RPM VE table by 1.148, but I tried that and the car would start, rev, die (Now that's all it does, even after flashing back to the way I had it).
I'm running 94171715 Tephra ROM..
Thanks guys.. much appreciated.
