Post up the OEM file as well as datalogs showing the issue and someone may be able to help.

Could you upload your OEM read and tuned file? I'm sure a few people on here can take a look

Do you know the ECU part number?

For anyone else on 259D box code, here is the final XDF I used to get MPI working. With those two tables added as well.

144130

Thank you! Did a quick test run with just 13635 mooned and no more limp mode!

Appreciate you! I'll give it a shot tomorrow!

The only change HPT picks up is the ECM 13635 "Max Fuel Flow Deviation", could you possibly share your XDF or the map FR map ID's of any others you...

So update, MPI is working it definitely triggers at WOT now. But getting a throttle closure and full limp mode (until key cycle) right around 5500k RPM.

Also throws a strange code: P1388 code at...

Hey guys, put together an XDF for anyone on this same box code and has user defined parameters.

Has pretty much all of the comb mode/inhibits that we should need to properly enable MPI at WOT.

Typically on the MED17(or MED9 for that matter) cars you really shouldn't have to mess with the period vs duration map for the MAF. It is not where you would adjust fueling like you would on some...

Hey guys,

Recently picked up a 2015 A3 2.0T as a small project, it came with an MPI kit (CTS) already installed. Looking into getting it activated on now.

I found a thread on here where someone...

If you zero out all three of the "Lambda Adder Mult. Var" maps (0,1,2) and then edit the six component protection target lambda maps to match what target lambda you actually want. (That way there is...

The richer fueling request is likely coming from the component protection tables. It is activated by modeled EGT. "Base Var 0,1,2" and "CM Var 0,1,2"

I appreciate that! I didn't want to start editing the axis values just incase it would throw things off.

Hey there,

I am running a 5G0906259D_0002 (Simos18.1/18.6) in my 2016 A3.

Applied the wastegate OS patch so that it is no longer using the FF logic but desired PUT / RPM. However the RPM axis...
