Torque Source- Trans shift Modulation

[Slowleen]

What cause trans shift modulation on torque source?
i think this is what is causing all my issues when going WOT but cant seem to find anything that it relates to?
Gen1 5.0 VMP Gen2R,jlt123,triple pump return system, 69mm upper, E85, id1050x.
maybe someone has run into this problem.. 1050x Tune E85.hptWot 3rd still sputter.hplwot sputter n slow rev wot.hpl

trq tables?

Your spark is briefly hitting over 30 degrees @WOT triggering massive KNOCK - keep doing that you will be looking for a new engine.

Fix your spark - it's entering BASE. You need to stay in BORDERLINE.

Other than that you are clipping your max load 2 - you also clipped your MAF. You must have a 1000hp there.

It's weird because his spark is not commanding anywhere near 30* on Borderline or MBT.

You need to lower the bottom row axis on your inverse table. This manipulates everything. You'll lower load, MAF lbs, and hopefully get you out of trans shift mod. Your Desired Load is around 1.6 and indicated torque. Here's on OP inverse I calculated using 700 as the axis.

700.0 1.7679 1.7286 1.6785 1.6627 1.6237 1.5901 1.5660 1.5560 1.5254 1.5104

Check his IAT spark table SMH...

[Slowleen]

I?ll give these parameters a look and adjust.. then report back my results.. thanks for the input guys

Funny thing is this is almost all stock in the spark tables for OP table.. it?s a RS3 calibration, it?s only going into 30* when trans shift comes out of. I where then the rickety starts

WOT op load change.hpl

ok so update made the changes car pulls smoother but still goes into trans shift mod?? around 5600-5900
that's when it spikes the timing and will give me knock so I let out.

[Slowleen]

I made some changes and car no longer hits limiter and stays in Borderline spark table all the way to 8k rpm.. ill post tune
WOT 8k.hpl

Much better now - torque follows the model, knock is constantly adding staying nicely in borderline but...

Your fuel trims still need some work - try to bring STFT close to 5%.

Your LOAD is still over 2 which suggest your boost is way over 15psi. If it is ignore this line.

yeah im currently working on stft I try to get them within 2-3% since E85 can fluctuate from tank to tank.

car has a 16 psi pulley.. and from what iv read air load usually pegs 2.0 when you have boost over a certain level.

[veeefour]

Theoretically 1 bar(atmospheric, 1bar MAP) = 1 Air Load, 1 bar of boost(1 bar over atmospheric,2 bar MAP) = Air Load 2 and so on. Of course air model is not perfect.

If you load it with 16psi of boost Air Load over 2 is expected but you should adjust your SD model up to Load 3(2,5 at least). Then you need to plot load 3(2,5) for your spark and torque.
