Where are LTFT and ignition adaptation stored?
« on: April 12, 2013, 10:46:20 AM »
Where are LTFT's stored? Not in eeprom 95040 from what I can see. During a couple of days I've been reading the eeprom with the ME7eeprom tool but I get a similar read every time even though fueltrims have changed when I check with VCDS.
Are there some other non-volatile memory? I've also read the eeprom memory mirror at 0x38xxxx and there are no indication there either so I don't think that LTFT are blocked from read by ME7eeprom tool.

:-) stupid me, hence why people often talk about disconnecting battery to clear adaptations. There is always power to ECU. Forgot about that one.
Thank you for your answer. Please forget that I asked. :-)
