Pretty sure you won't be able to read out the COS5 tune with HP Tuners so you won't be able to modify it. Best bet is to modify the tune as far as you can within the confines of the factory OS, then...

The problem is when I go to BBX F5, my Gas ECM selections are limited to LS1A, LS1B, E40, E38, E67 (plus a few diesel controllers). There is no E78 to select. Now if somebody can walk me through how...
I have a remote tuning customer with a 2012 GMC Sierra 6.0L 2500 HD with the E78/T43 combo. I don't see an E78 tab for programming the Autocal. Will it work with E78 and if so, how do I go about...
I occasionally fight a strange issue with cammed E38 cars commanding a very lean A/F ratio (like 16:1) in closed loop for short times during idle. This makes the idle very rough when this happens.

Because I have so many Autocal customers with the old .ctd file supporting software, I have saved a copy of V7.5.7 Build 180. I open up their tune files with the old version of V7 and I can still...
Apparently begging and pleading aren't enough. Perhaps bribing is worth a try. Slohawk and Minytrkr are correct, this is really the only table that needs to be added to the trans tuning file to give...
I've tried the new ECM torque modeling tables on 6 different tunes. Compared with my best previous TCM tunes, I think there has been some incremental improvements, but time will tell. I've...
Your trans shifts off mph primarily. The swap from 2.92 gears to 3.45 gears means you'll now need to reduce all shift mph tables (don't forget the TCC tables too) to 85% of their original value. If...
How can one obtain these new calz files? I need them ASAP. Thanks!
These tables cannot be that hard to add. Come on Ross and Paul, you guys are losing market share and future petrol customers to HP Tuners. These people may never come back. Please make these TCC slip...
Very sad. He was always quick to offer help to others. A true gentleman. Shawn will be missed for sure.
In the US, our gas is getting worse. We are seeing 10% ethanol at most pumps and 15% is coming soon. As I log commanded AFR, I see it drop from 14.68:1 to more like 14.3 or 14.1 with the ethanol...
Not an error. Every single 6L80E I have ever tuned has the same 2-3 adaptive at 40. Every G8 GT, G8 GXP, 2010 Camaro, Yukon Denali, Cadillac Escalade, Cadillac XLR-V, Corvette, and Silverado I've...
Any idea why the 2-3 shift max adapt volume (D9264) is 40 while the rest of the shifts are 200? Would this narrowed learning volume explain why some of us have light load 2-3 shift flares, but solid...
Do you want to put the car on a dyno or are you just looking for the best modified tables for a bolt-on 2010 M6 Camaro?
This is very good advice.
I have TM fully engaged, but I modify the minimum final timing spark table (B5157) to reduce the timing reduction at higher rpm and loads. This way, I have smooth TM...
Another thing contributing to your problems have to do with your Commanded Fuel in Open Loop (B3605). Your table has you at 1.13 A/F ratio from 75kPa up which is right off idle with the cam you have....
I've been doing that Ross, but the changes to the vacuum enable/disable tables seem to be counter-intuitive. First, I changed my TSP max from 6% to 40%. Then I would raise the kPa readings of the...
Ross,
The cal file that I received from Jesse Bubb does not have near as many parameters as what is available with other programs. There are TPS and rpm hysteresis parameters plus various timing...
Ross, while the cal file that Wait4me sent me has tables I can manipulate, I'm not sure if they are doing anything. Jesse, if you can chime in, that would be great.
I've received a beta cal file from Wait4me. It's pretty cool. I've been playing with the settings. They are not very intuitive and have taken lots of trial and error. I think I'm making a difference...
Thanks Ross,
I don't want to disable mine, I want it to work more often/better. With my new tune, the fuel economy has picked up overall, but I have a feeling that GM was way too conservative...
I agree with you about a good tune improving mileage. I had a very good tune in my 2002 Suburban that improved fuel economy. But, if a regular 5.3L tune surges horribly in a newer 5.3L AFM...
I have a 2007 Suburban. I also have EFI Live with the V2 programmer and all the latest updates. Am I able to modify the Active Fuel Mgt. portion of my program? It's very difficult for the motor to...
Maybe I'm going about it the wrong way.
My long term idle trims are pretty close to 0% and my short term idle trims look good except for startups...especially hot re-starts.
My short term idle...
