Loaded 2Bar enahancement on 2011 GS/Callaway-rough/die

[rwj383]

Ok, no newbie to Gen 3 tuning for sure but first time tuning Gen IV. I have a 2011 Corvette GS/Callaway (TVS2300 blower), brand new car. I ordered the additional license + 2Bar SD enhancement. As soon as I load the 2Bar the car starts, bucks and snorts, dies. I reloaded original default tune Write Entire, got back to starting point, car runs normal. So then, I simply wanted to make a small change to the tune: fans. I set both Fans Desired % to 100% in all boxes, then under Fan Relay Controls I set State VS Desired % from all 0's to all 100%. Again car would start but sputter and die. I then set State VS Desired back to all 0%, now car idle normal, fans now on even at cold temp. So I assume the Fans Relay Controls/ State VS Desired does not apply to this car because it is Pulse Width Modulated fan?

Last question- I 'assumed' this Callaway-converted vehicle would have included a MAP upgrade to 2bar. All MAP tables appear to scale to a 2Bar setup. But since car runs poorly with 2Bar Enhancement enabled, it must have stock 1 bar. Where can I get a 2Bar MAP?

Did you populate the VE table? They're all zeros in the COS until you populate them. Probably your problem. Without a tune and data log, hard to say.

The fans, you can't set to 100% across the board, or they will run continuosly.

The MAP sensor should be fine. It has nothing to do with why it won't run.

If the programmed MAP sensor linear and offset values are for a 2 bar sensor, and you still have a 1 bar sensor, it'll run really goofy at idle. I had this happen once when I programmed in for a LS9 MAP sensor in a vehicle that didn't actually have one (installer didn't realize he put in the wrong part number). It was a stock LS3 with a D1, and would idle surge like crazy. As soon as I corrected the MAP sensor values, it was fine. I'd check that, and also populate the VE table with something other than zeros. Flip the car to pure MAF mode, and see what it does.

Edcmat and DSteck- thanks, I will start scanning w WBO2 to populate the VE table (yes, it is all 0's). I also need to get a 2bar MAP, the LS9 MAP is 2Bar plug-n-play?

Thanks

LS9 MAP is 3 bar, but for an LS3 engine, it will be plug and play. You just need to enter the proper linear and offset calibration values, which I can't pull up right now since I don't have my normal laptop.

you can use 05 vette VE stock table for start ..

resolution is completely different, but i did use portions of it and then interpolated it build a base, then use the wide band to tune from there... works great
