@mss

That means I just have to disable EGT (and VVT) and ECU will follow LAMFA?
That's right.

Maybe you need to learn to tune then. Lambda 1 at 3/4 throttle will get you there VERY fast.

If you modify lamfa at part throttle you kill fuel economy because enrichment happens when it is not needed.
There is no sense to ever modify anything BUT the last row in LAMFA, or over 95%.

Agreed 100%

As usual prj is right, IMO

guys,

I did conversion on APY. Use software 8N0906018BH, coded out o2, sai and vvt by codes (CDNWS, ESKONF).
Till now no faults on engine, LTFT trims looks ok, but i have problem on original BAM software with actual boost,
it's 0.2bar under required boost, n75 duty cycle is not going up!

Looks like software is cutting boost.

Is there any maps related with VVT which should i touch?

hello, also make a conversion to wideband in apy.recomienda engine the file of 018j to restore control of the engine as close to apy stock but with broadband? sai eliminate vvt o2 back etc ... would also have to modify linearizations of maf and the calculation of injectors (tvub). I am currently only looking for information to have a base-I will share all my advances to help make the conversion to others  Wink Wink Wink
