did you ever figure this out? im dealing with issues trying to get a friends truck to shift later as well.

Thank you for the suggestion but it did not work. To me it seems like a limit is on somewhere. What should I be logging to see what's commanding the shift rpm?

Give it time. Once more people mess with it there will be more free resources just like other platforms. I'm just asking to raise shift points not magic to make the car half a second quicker in the...

I have looked at a few tunes out there like the stock whipple tune and a few others on this forum. I also read some posts discussing this same issue and can't get the thing to work how I want it to....

That doesn't explain why the speed limiter removal is not taking.

I upped the mph under the limiter tab on a few things but there is no "source" for calibration box so I can't change it from GMLAN to calibration. What am I missing?

Alright so I was able to make a pull after setting PE to 1 and taking some out of the MAF. I do see airmass dropped from 1.6 to 1.28 so it follows that the tq reading is much lower. I still get full...

As an update, I figured out a few things. VE is now good. My first wrong step was using manifold switch closed table and not the open table. I have modified the VE as much as I can in purely SD mode...

Can you post a log of what it is doing?

I think I will just start over from stock. The VVE table is so jacked up it's probably the crazy bad transitions that are messing with it.

It's massively lean but do you see in the VVE that it should be extremely rich? I added over 20% of fuel in that area 2x and it made no difference. The scalar number I got from the maker of the...

I mean im on the throttle light as a feather and its this transition from 5% to about 12% throttle thats having the nasty bucking. I added more and more fuel and it made not difference. The maf...

But whats the actual issue here?

I was able to get idle dialed in fairly quick after a few revisions and then I attempted to drive the car and there was horrible bucking and jerking. I could see the wideband going lean. The thing...

Are you saying the pe floor cannot be made leaner? I tried what I had mentioned to Ben about changed the open loop eq gas and alcohol tables and that had no effect.

I need the meth more down low than up top.

It's two 14gph nozzles. Before when I had an inline solenoid it was spraying less than it is now with no solenoid even though I had dc set to 100% at 6 psi and I'm at 16psi. I wanted to avoid taking...

Just curious Ben, what's your preferred way of tuning meth? With the pe table or maf?

That's what I'm getting at. So the ecu is using whatever is the richest fuel pe or open loop gas/alcohol which is causing me to run into this limit of eq commanded not going leaner than 1.0

How I am tuning the meth is with power enrichment. I prefer to do it that way. I recently made some changes to how the meth gets delivered and got rid of the solenoid and opted for a...

under tq mgmt, driver demand for map a b and c your dd table takes off like a rocket past 50% accel pedal. dial it back under 80% accelerator pedal

on pump 93 probably not more than 20-22 up top.

Do a throttle body relearn.

I updated the throttle area max from stock to 7200 and was working on vve and maf. Went wot in 3rd for a split second and it seemed fine. Went wot again in 2nd and i felt the power then...
