17 mustang gt will not enter fuel enrichment

[mbray01]

Been banging my head for a while now on this one. I have tried different enable criteria going up, and going down. have maxed torque management, and have kept it within reason. My torque tables coincide with where it should be. A lot of the file is based on a roush strategy. This car has a vmp stage 2r pd blower. with 95lb injectors. Fuel trims are within a couple percent. I have changed everything conceivable that i know has anything to do with enabling wot fueling,yet i get none. the ecm commands 1.0 lambda at wot no matter what i do, when i back off of the throttle ironically i get commanded wot lambda.
heres the current file, which i changed some torque limits(its closing the throttle on me now, so it goes back tomorrow, but it did not change any fueling for me. I will get a log tomorrow

Max map above baro in the speed density section is set to 0. Try increasing this to the correct values and see if it helps. Fueling can get weird when a few of these types of values aren't correct.

Letting off and stepping back in, gives you a Lamda 0,85 because of Catalyst Reactivation after tipout and fuelcut was present.
Yes a log would be helpfull.

not letting out, and stepping back in, just letting out. after a full throttle pull it stays 1.0 lambda at full throttle, once i let off it commands lambda .82

well that is definitely not it. changing it to anything other than zero, makes the car absolutely undriveable. 0-50% ap the throttle stays closed, over 50% ap the throttle goes wide open. basically makes the throttle body on/off. It also does not enable fueling either. I checked through all the roush, vmp, whipple, and any other strategies i could find, and they all are at 0

turning it back off and gonna go get a descent log in this

[mbray01]

log 1 is with map above baro set to 86kpa, and throttle basically going on/off but not fuel enrichment

log 2 is from sunday, again no fuel enrichment

Could it be due to your maximum load for OP(ECM 43476) is still set to 1.0? I see where you had changed the values in "Load at WOT"(ECM 44353) to account for the supercharger.

I'm still new to Coyote tuning so this may not be your issue....

try this, not 100% sure it'll fix your issue, but just wen through it really fast and changed a few things, that's your file, you can just write calibration for it.

[Slowleen]

see if you can find a stock roush tune with the same strategy as your current pcm and copy everything. only changing some values in the torque tables can make a world of headaches. iv done this before and it wasn't fun once I found a stock roush tune that I could copy all over it made it way easier for me.

1 thing I noticed is that your OP Power Enable Pedal Position table 38171 should be all 0's to remove this as a variable, your Fuel Enrichment Pedal Table 32732 looks good, although I would use 30% at 4500 and 10% at 5500 and 6500 to keep things cool up top, light load and high rpm create lots of heat.

These 2 tables are not the same thing.

Jn2 I am forever in your debt.
first drive with your file I noticed I was getting enrichment under low boost, which was good, however once I went WOT it kicked a bunch of torque errors. Some quick drivers demand changes, and its all happy.
Thank You sir.
Now to the dyno to finish the torque tables, and start getting some timing in this thing

yeah I didn't touch your DD tables or actual torque tables, don't have that kinda time, but glad you got it going now

I wouldnt expect you too, you helped with exactly what I needed. The rest I am more than capable of doing, just couldnt wrap my head around this issue. I see now my error, and honestly knew better. Again I am thankful for your help. Makes 655 with the tires spinning on the dyno(255's, had 8 batteries, and 2 large guys in the trunk, 2 guys in the back seat, and still spun on dyno), and a roush intake that was collapsing under wot, so was amazed we read 655. Drives perfect, no stumble, no surging. all and all came out well
some tires and a jlt intake and Im pretty confident it will make 7

Would you mind sharing What changes you made to fix this issue?

I don't remember, I opened his file, made the changes by glance, saved it, and posted it.

Not at my laptop, but essentially, to correct the driver demand issues, the torque tables were reading about 700ft/lbs under WOT. I lowered them a tad as that was high, and the driver demand tables were only asking for about 525ft/lbs, so it threw the wrench, and started injector disable. I raised the dd tables to coincide with the torque tables and all is well.
You have to raise the torque error over 125,000 to get it to not fail, then once you dial everything in, lower it back to stock and all is happy

Badass thanks for the info
