So overall the car is running good. I have 250 miles on the motor now, very drivable and my AFR's are pretty dang close to ideal without 02 driven correction on.
I just have 2 slight problems
1) Bouncy Idle after ~ 5 mins of driving
- Im presuming what is happening here is after the car starts and idles normally, I drive for a few minutes and it goes into closed loop control. Its bouncing between 2 cells on my VE table. The values were a bit far apart and was a bit lean on the "more vacuum" cell. I adjusted this value closer to the value above it one the table, the AFR is more deserable, and it tightened up the range of the bounce in the idle. I do not want to move this value any more because the AFR is correct. My idle is high ~1500, I can bring that down a bit with the IAC screw.
I guess my question is am I looking at a closed loop settings issue, or a idle RPM issue? It seems like my idle is high and its trying to adjust it lower, then it pops back up to normal.
2) Lean on Decel
- Whenever I let off the gas 100%, foot off the pedal while in gear, the wideband will lean out for a split second. The car stutters ever so slightly and then it pops back to normal. If I toss it in neutral and use the brakes I have no problems, its only when engine braking (decel in gear)
Turn decel enrich off is set to never.
AND now that I think about it these might be related. I never did calibrate TPS after the engine swap. I will try that tommorow morning along with lowering the idle. If anyone has any other suggestions feel free to speak up.
Calibrated the TPS the bouncing idle went away. I still have the lean on decel problem. You can see in this prnt scrn that the duty cycle and pulse width drop to 0 esentially shutting the injectors off.
Also notice the AFR spikes when vacuum increases (let off throttle)
I have not made the change, but just looking at the MSQ I can easily tell it is the over run fuel cut. I will make the change and Im sure it will solve my problem. Thanks for the help, I cant beleive I missed that setting :sigh:
Edit - That should also help with all my other lean spikes as well looking at the datalog again. This puppy should be running prime after this change, just 200 more miles and its going on the dyno.
