First off I am no expert with using DSMLINK so any help would be appreciated.
I have recently installed FIC 1120 injectors in my car. i have played with maf comp and dead time for a few days and i am fighting a idle surge once the coolant temp gets over 200 degrees. with stock injectors car had no idle issue. I have boost leaked tested many times and it holds 25 psi. i have not been able to get the isc to maintain 30 due to the idle surge, RPM target is set for 750 but idle will jump +/- 100+ RPM as the the 02 cycles. for this log i set the maf comp back to zero and dead time to ECMlink starting point to get a starting point. again i have tried many adjustments to no avail. RPM starts to jump once cooling fans kick on, i can turn the car off and start back up and it will idle perfect untill the fans start to kick on then idle goes all over. take a look and see what you guys think i could try. My mod profile is up to date.
