90556701 v7 sd 7 ecu

Recently flashed this rom to get rid of my MAF. AFR is good on full throttle. Runs lean on idle and part throttle. Turned closed loop on. AFR stabilized. On part or full throttle around 2.5k rpm goes lean and back to normal for a sec. Is that the jitters people on about?. New to SD so might need help setting it up. what do I need to change coming from a MAF 9055 V7 rom

This is a weird one. So I had to change my 7 ecu. Someone sold me an 8 ecu instead. So I changed the 2 pins around to get the car running. The code p0135 heater circuit keeps coming up. I'm using rom 90552701-v7. same one I was using on my 7 ECU. I turned the rear o2 off. I look for everything I can through the rom. nothing helped. so I checked sensor resistance. Reading 14ohms. Ecu was grounding the heater circuit the heater but fault still there. I changed the sensor. The code still come up. Flashed it with rom 96532706-TephraMod. it does not come up anymore. Running fine. I don't get it.

If I do that, I get random afr reading on close loop. Plus the drive is horrible. Do you guys know any good E8 Roms. Am using one now. It picks up random knock reducing my timing sometimes and would give me MDP code randomly

Make sure you have the ROM with the WGDC fixes under the Misc tephra mods.

Hi could anyone here advise why theres is no IAT Scaling table for this Rom?

Lastly, does this 90556701 Rom got Live tuning features?

Thanks

Ya and then you break multiple things in the rom like fuel trims. Your better off using the 965 series roms that dont have those issues.
