Also curious on 2021/22 GM SUV's. Since the suv's also use a e90 ecm, that there is still a problem getting past the security of the new VIP architecture. Otherwise, I would be willing to bet the...

I have remove VATS(w/ write entire), starter checks, and DTC's that are not needed. Have spark, but do not have any commanded fuel injector pulse. I have also tried the same with EFI Live, still...

Doesnt matter what the BCM is, doesn't even have to be programmed to any one vehicle. BCM need to power up with CAN in a loop through the BCM and low speed to dlc.

Bringing this back from the dead again!

I have figured out the issue with the off board programming error message. The reason why efi connections harness works is because they include the low...

I used an adjustable timing set, because I was unsure where the ICL would be, but ended up at being straight up. Now im thinking about advancing the cam another 2-3* and see where the torque curve...

Well at some point in the next year, year and half it has to get fixed. have emissions to pass again

Cant use the LS7 rockers on a LS3 head, I did trunnion upgrade on the stock 1.7 rockers. Also the Intake centerline is 120* on a ls3 vs the 123* on an LS7. Crank gear is degreed different.

I was quite surprised by the power, haven't toed anything. power and torque were respectable 381tq 366hp. has 300 tq by 2500rpm, pulls to about 6300 rpm

As tittle says 2011 GMC Sierra 6.2L. Just installed LS7 and removed/ converted to LS3 front cover. I have turned off all necessary DTC's and drop downs for removing VVT. Trucks runs very well, but...

stock 97 T/A tach and cluster. I have tried so many settings hoping to get something to work. installed a Dakota digital tach adapter box, still not working properly. I can get it read very close at...

Come on, no one has had this issue?

Finishing up a 97 t/a 6 speed with 24x conversion (0411 pcm). I have been playing with the tach output high and low setting in the tune, and setting both to 3 the tach reads really high, and when I...

if you got noise in a valve cover, pull it off and take a look, also you might check to see if the noise is in the supercharger, could be the coupler

I have been playing with this VVT stuff in my 2010 escalade L94 6.2L, I am pulling in 2* increments from 2800rpm and at 6k and up rpm I am at 15* retarded on the table, which would put me about 6.5*...

I know there has been much talk about adding ABS functionality. It would at least be nice to read and erase the codes, and maybe as a bonus look at sensor data. Maybe this would pave the way for bi...

I wish I had access to a dyno, and hence I would probably not be asking my question. what I am currently running in it now is only retarded by about 3-4 degrees max, and it feels stronger above 4k...

Nobody ?

Bump

I have been playing around with the VVT tables and I am definitely seeing improvement, but I would like some input weather or not I am taking this to far. This is a 2010 Escalade L94 6.2l (VVT and...

bump as well

it is through 2.25 beta

anyone have an idea

I tried lowering the shift points and I also tried copy and pasting from the normal map with no change. It seems to be a logic in the OS as to how map a will shift.

would this change how...

I tried just lowering the speed in the lower TPS regions and it still got violent on the downshift crap, so now I copy and pasted the "normal map" to the "a map" and multiplied it by 10%.

if your having KR problems I would try a set of NGK BR7EF plugs. they are not projected tip vs. a projected tip on a tr6 or tr55. I was fighting KR on my 98 Regal GS running 11.5lbs and I was using a...
