Hello,

Recently I've successfully remapped some VW TDI ECUs using a lot of guides and data available.

Now I'm facing 4cyl 1.6Ti ford engine (HXDA) which have 2 cats and so 4(yes four) O2 sensors. I want to drop 2 cats and do proper 4 in 2 in 1 exhaust with one O2 sensor, so 3 other O2 sensors must not produce errors and ECU has to use one(or mb 2 of them) lambda for corrections.

Are there some data on how to remap HXDA ford engine (lambda Hysteresis table/values addresses)? Some "decat" examples?

Any info is appreciated due to lack of such info in google.

Thanks in advance!
