Remember the part where I said it get's sticky. The LS2 E-Force tune is scaled or proportional. Their tune says you have .56L per cylinder where in fact you have .75L per cylinder.
Once you get to the tuners, reload your stock tune, then let him adjust your stock tune for the E-Force. You won't want anything from the E-Force tune in there. Your tuner can adjust for the MAP, MAF, IFR, timing, and all that other junk to get your car purring!

Hi guys, just heard back from my tuner. My car does have the stock 2006 C6 A6 tune in there prior to the Edlebrock flash. I am going to find out from Edlebrock why I lost the paddle function and 5th, 6th gear. The car runs fine right now just pig rich and if I can get my paddle shift plus 5th and 6th back, I should be pretty happy. I will keep you guys updated on what Edlebrock says.

...disagree on this one. At an absolute minimum his tuner is going to need the parameters for the TMAP to populate the Map Sensor values, he'll need the parameters for the IAT sensor curve, he'll need the injector values and probably a few other things I can't remember at the moment. I'd start with the Edelbrock tune and build from there.
I know my ls2 tune was in trouble until we got the tmap and IAT curve from Chris at Edelbrock.
Do we need to compare notes on this?

Hi
I had the same problem with the transmission when i flash the ecu the first time.
My transmission was stuck on one gear only and the paddle shifter didn't work.
I think the problem was in the transmission parameter.
When i put the torque specs back to original the transmission works OK.
I've flash the latest tune from Edelbrock and now everything works well.

Hi guys, here is the latest update on my problem.
Talked to Chris from Edlebrock who is a great guy, he said that they had some problem with 2006 A6 and the latest update should take care of the transmission problem.
I downloaded the software and sure enough I got my A6 paddle function back. Drove the car around for a while and it is pretty good. Now I just need to get my tuner to do some minor adjustments and I should be fine.
I do know that my instant mileage is probably off, can that be adjusted?

Did your tune use the .56 or was it a full scaled tune? The ls3s don't use the scaled tune (I could be wrong) and the data in those is fine. All of my LS2 settings are scaled for the 25% reduction in values.

Elmer,
Edelbrock's Calibration for my 06 LS2 A6 Lists Cylinder Vol at 0.56250L. My OEM Calibration lists Cylinder Vol at 0.75L. I am not in favor of scaling or otherwise pumping in data to fool the system (VCM). Not sure where I will end up with my tune but I would prefer not to scale my tune unless it's ultimately my only option.

or if you call Edelbrock and ask about the information? Since Edelbrock changed scales that I believe are not normally adjusted and did not publish the data, it might have been necessary to call and ask.
Then again, maybe not. In any event, Edelbrock tunes, so far, CANNOT solve my issue.

Most will start with the edelbroc file and tweak from there, but I personally choose to remap my own ve tables. There have been too many problems with the supplied files to waste time using them IMO.
OP, your paddles not functioning is 100% tune related.

The latest Edelbrock SCT Tune Version is 1.2.2E. You can verify the latest tune loaded on your SCT programer by scrolling over to and selecting Device Info and then scrolling down to Tune Version. If Version 1.2.2E is not listed, you must access the Edelbrock web site to pull down this latest version per their download instructions.

I did take the car for a quick drive and it is a lot more fun than the Vortech supercharger it replaced even though it is running very rich. The low end torque is instant and is a lot of fun for the street. The power comes on around 2500rpm vs 4500-5000 for my vortech. I don't run the 1/4 mile track so the loss of top end HP doesn't really bother me.
My instant mileage is higher than before which I think is a mistake, not sure what I can do to make it measure correctly but not a real big deal however I do hope my tuner can fix this if possible.

Thanks, I did download the latest software off their site and it did fix my A6 transmission problem so now I have paddle function again. I do need to have my car fine tuned since I have LG headers.

I am using the non-proportional tune in my car so my DIC reads correctly.

INSTANT mileage is off and will STAY off as long as you use the E-Force tune. The 2006 & 2007 LS2 tunes are PROPORTIONAL. They have to lie (ECM limitations) to the ECM and tell it that the engine is smaller than it is. Look at your cylinder volume in the E-Force tune. IT is set to .56L and your engine is .75L per cylinder. The tables in the tune are reduced by 25% to make the proportional tune. Your instant mileage and the "miles remaining" are hosed. The ONLY way to get your DIC back to normal readings is to put a NON-Proportional tune in the car via an independent tuner. The E-Force tune will stay proportional and your DIC is broke.

My DIC and mileage numbers are spot on so I assume thats how mine was tuned by Doug. Once again it's another reason I'm glad I used a place like ECS to do mine. My issues have been almost non existent so it was money well spent imo....

As a note:
The LS3 tunes by E-Force are NOT proportional. The DIC readings on LS3 tunes are accurate. Only the LS2 tunes are proportional.

Can this be done by HP tuner? Is so, how and where do you get the Non-proportional tune? I would like to give all this information to my tuner just in case he doesn't know it. It would be nice if my DIC works since that will let me know roughly how far I can go with the gas I have.
If the tuner takes your stock tune and adjusts it for the E-Force, you will have a non-proportional tune in the car. The HPTuners will do the job just fine.
