HPT has a very logical layout to these kinds of things. Something PCMtec is lacking very much.

I think Rolls said he would group things better if we point it out to him.

Seems to be working great. Thanks for pushing me to revist using existing mapped points. I don't know what I had wrong for it to be upset the first time I tried.

Is the spark still too high?

 

[tdstuart]

In a log check what your spark source is while its lopping. That tells you what to modify the spark with.

Just make sure you give it enough time to settle.

Modifying things blindly is not good.

Not included in the log I just sent but it bounces between borderline and torque control

At idle the spark source should be torque control because of how ford controls idle.

@K4fxd I submit tickets to ask for things to be reorganized in the trees. It’s just there are so many…

Its tough as there will be differing opinions on logical.

 

[tdstuart]

How much spark should I be targeting? And is there a way to stop the car from going so rich while chopping?

I want to make a write up on the solution and post it in the other thread I created on this issue. I want to have a good base file I can give out.

Drivability seems good, no flare ups, no idle issues so far.

Try the O2 settings from the track key tune. Ford changed the settings in the idle area

I thought you told me to not mess with torque control spark settings.

I guess its ok cause you actually have aftermarket cams in it.

I adjusted the bias how the boss track key has it but car is still wanting to add 8-9% fuel. Heavily on bank 1 for some reason. Bank 2 is only like 2-3%.

Should I just add more bias or is there something else I can play with?

Fuel tab> openloop> Lost fuel > VCT.

IDK the table in PCMtec, but add some 0.1's in the idle areas for load and ECT.

The CL fueling has error that the O2 sensors them selfs are reporting due to air getting into the exhaust. Could be because of the potential misfire conditions or just the overlap itself.

Found it in PCMtec

I already have zeroed out Closed Loop Fuel PI Control - Proportional Term and Closed Loop Fuel PI Control - Integral Term at rpm 600-1000 for load 0.1-0.2 because someone on the forums said it would help with fuel correction with the misfires

Does yours say what the difference between them is? Looks like yours shows more info than mine
