Hi. It's been suggested I should reset my ECU since the car is running badly following a MAF change. The car was remapped a while ago to take advantage of a number of engine mods. If I reset the ECU will I not lose that remap and end up back at factory settings?

No,the map will still be on there.
You are best off resetting after fitting a Maf anyway.

Nope, the map will remain the same but any learned values will be lost. The ECU will take a little bit of time to relearn the values so you should expect it to perhaps not be just as quick initially.

Okay fellas. You've put my mind at rest. Thank you.
