This is really the easiest way. It only takes a couple minutes.

Thanks for posting this. I've got various issues with mine that I have not had time to work on. Finally got a day off and if I get it working better today I'll go to the track tonight.

I've had...

Am I looking at your log wrong or do you not log current gear?
I log it so I can see when the shift was commanded as opposed to when it occurred.
Also, TPS is not showing and I'm trying to figure...

I'm still trying to get my full throttle shifts where I want them. So far I've had better luck using the mph. I've currently got the RPM way low and it looks like that might work for me. Worst...

I seem to have better luck with the MPH. Mine pretty much ignores the RPM.

You didn't change tire size, did you?

I have to set my shift points (RPM) way low to get the car to shift properly at WOT.

I don't know anything about if / how the trans learns.

In case you don't have this :

2009-2010 ZR1 and CTS-V injector calibration data
differential pressure Injector Flow Base
kPa psi Grams/sec Lbs/hr
128 18.6 3.79 30.1
144 20.9 4.06 32.2...

I'm on 2.23.248.
I can log now without the PC (I am SO happy this works now!), but cannot log the WB.

Am I understanding correctly that this is a known issue and will be addressed at some...

Very interesting indeed. Keep us updated.

This is very interesting to me as I have an 08 Vette with the E-Force. I don't understand why your tune is scaled as the injectors with the kit are the 52 (some say 56) # LS9 injectors. Did you...

I seem to have a delay of about .3 seconds after hitting the gas per my logs. It feels longer when I'm in the car.

Guess I better have another look at mine. I've pretty much resolved myself to rebuilding the trans, but I think this shows I should put in a little more tuning effort in before throwing in the towel....

Hoping you have had some luck.

I'm still fighting the same problem. I went back to the track this weekend after using most of the settings in the tune Subfloor graciously posted. I only made two...

Looks like I'm back to scaling the tune or finding out if I can live with smaller injectors. Any other suggestions are appreciated.

Thanks again to all. Lots of really great information here.

Guess I better look at the sticky next. Thanks to all who contributed so far.

That is a big thread. I want to do some reading and I'll post up after.

Thanks

This might be just what I need

Hadn't thought about that. Scaling with the A6 has not been working so well in the tests I've done and I'm exploring some alternatives.

My 08 Corvette with E38 has the 63.5 lb limit in the IFR table. I have looked at tune for 2009 Corvettes, also using the E38 and they do not have the limit.
Can I upgrade the OS on my ECM, or...

Went back to the track yesterday and had the same problem. Won't be going back until it is resolved. Just hoping I did not already damage the trans.

Had a similar problem with my 08 Vette the one and only time I went to the track a few weeks back. I'm planning on going today if I can get finished work. I'll report back if I have anything new to...
