Hello,
I am having some trouble with tuning in an M52 engine. It's hunting really bad, even though I set everything at one specific value.
Keep in mind this is in fact my first full sequential build
850cc injectors à là chineesium, Turbo, stock internals, stock everyting else...

Either the wideband isn't working, or you're running pig rich.
Normally an M52 would have a three wide IAC valve - has this been swapped for some other part?

Running a seperate innovative mtx afr gauge.
The idle valve is swapped to a 2 lead spring returned style. Sorry, i forgot to add.

Wiring the MTX-L to the ECU will give you a lot more tuning data.
