The Strategy code (MDE2). Looking forward to hear from you.

Manual Tr3650, Semiens Dekka 80lb injectors, Blow throw MAF (SCT BA5000) in 3.5 inch pipes. For strategy if I'm not mistaken (MEA2)., i will double check when i get back to my laptop.

How to tell if i already hit them? which parameter will monitor them?
do i have to just raise the numbers by 10-20% and call it done and see how it will act? or this is wrong

Ok Decipha fair enough. So, getting back to my main question is why Fuel source will go to #3 which is "Cylinder cutout-Stabilized - STFT controlled by torque control feature", and if i understand you right that this is something to do with (torque modulation or torque truncation). Therefore, I haven't touched those tables at all. So, do I have to do something with them or leave them as it is?

Ok why this happened?

The car run fine all the time with good datalog monitoring. Only this time accured after multiple abuse with hard shifting 3rd to 4th continously. Can a fuel pumps about to fail cause this to happen as fuel prssure get dropped at high rpm? As i can see the Inj pulse width B1 and B2 get dropped from 4500 to 2300 and car get spike lean with fuel cutout and engine shutting down.

What will cause the Fuel source to switch from 5 to 3 (Cylinder cutout-Stabilized - STFT controlled by torque control feature) during shift from 3rd to 4th gear at WOT which cause the AFR to go lean?

I already tried logging the torque source and at WOT when tge issue accured and throttle close the torque source was reading 13 and shift to 15 and get back to 13. It was doing it back and forth. So, torque source 13 is "Tip in Torque Control" and "OSCMOD". So to fix the issue should i disable the Tip in Active Switch or what?

We datalog it and we found that at WOT before 4000 rpm the TB will close but if we go in 3rd gear and pass the 48 mph and shift to 4th and WOT immediately it will work fine with no TB close. Its kind of strange.
