Help! At the end of my rope

[sneaky98gt]

The OP claimed that he flashed stock files in and the problem still presented itself.

To be honest, I missed that post. If the issue is still there with both stock files in, it pretty much has to be hardware related.

have you tried out my automatic defuel calculator? I uploaded it to the V3 timing thread but that one is pretty fat now and hard to find amongst all the other posts. but I have it in this thread too

Calculators

Is there a way to collect up all of the latest spreadsheets, calculators, and other tools from the various threads and maybe link them into one sticky or perhaps the tool tab at the top? Maybe when one makes a useful tool, one or more mods can review it and if it passes muster then adds it to...

I forget which one or version it was that I first saw. I'd have to check my other computer. I remember having to basically guess and check the values in a couple of tables until an output table was 0 or close to it. Something like that. It was around that time that I realized what was going on, and with some Excel voodoo, was able to automatically calculate those out.

yeah mine automatically calculates them out too

TCM/ECM defuel discussion

Once again I think you misunderstood Brad. the 6000 rpm shift is what he is referring to when he says "as to when they occur". we are not referring to the quality or fractions of a second in changes to the shift because defueling is off or there is something going on with throttle. the TCM is...

2nd half of 41 & 42 can move

I'll go out on a limb and say I would bet money that it is a transmission problem causing a rough shift and not an electrical or calibration issue.

Done. Enjoy.

There’s another shop in lower WI (Top Gear Performance if I recall correctly) who just did a customers trans because a 2 week wait was too long. Long story short, the customer told me what was in it and it’s not at all right (luckily his is an LBZ so there was no full transgo to muck up).

I just want to read about more parts being thrown at it honestly

Update:

The OP stated the stock tune was put back in, he didn't specify if it was just the TCM or the ECM as well. The post in question is #9. It is certainly possible that the ECM was not touched.

@DarylF, was the ECM returned to stock as well or just the TCM?

Just the ECM, not Dan's TCM

Update:

Just the ECM, not Dan's TCM

Why not the TCM? The only way to 100% ensure it’s not a tune issue is to run OEM calibrations in both the ECM/TCM as there are tables that do communicate together and must have data that is realistic between them.
