????? - ANY transmission with excessive overlap WILL destroy itself - INCLUDING 4L60E's and 4L80E's. The allison in not special.

So..... a trans can have no "defuel" and live but if it has no...

I know....I've gone through them all and every torque limit in the trans program (including tq/throttle pos) exceeds the tq values set/produced in the engine program. Since the truck, under light...

I have removed every limit I can find in the trans AND engine program.... what parameter specifically is "defuel"?

I already have firmed up the shifts by reducing the desired shift times and we are looking at installing a TransGo JR shift kit HOWEVER, regardless of how nicely the trans shifts, there is still the...

I've got a 2007 LMM Duramax with an exhaust and a mild tune -I've turned off the tq reduction request option in the trans tune which made it shift much better HOWEVER, monitoring "driver demanded...

I would like to re-visit this post as I too have asked about this function (twice) and never received any reply. I even sent in a screen shot of the table from LS1_Edit. I have a customer that...

All of which have already been done....

Is this considered a standard way to handle this issue?.... I installed a cam (224/228-114) in a trailblazer SS LS2 with stock injectors -- to get the fuel trims where they belong, I modified the VE...

The VVE table HAS been set up properly..... this car has a cam in it w/ long tubes - the engine moves less air at low speed and low MAP pressure. It starts and drives flawlessly with computed (speed...

?????????

What about turning B8037 and B8038 up to 100? Is there an airflow model in the background and when the actual MAP exceeds the error limits in these params, it defaults to this background airflow...

Here is the tune file and data log.... note that the log was with a tune that had a 3000 RPM switch point for high speed mode. Check the beginning of the run... note the inj pw and air/cyl just...

B8034 is set to 200 kpa. All the VVE tables have had their coefficients altered to the same parameters - as I said, the scans show the ECM is seeing the correct MAP pressure and air mass entering...

What is the reason that an E38 ECM in a boosted application will not recognize higher than stock air mass at low RPM (below the "high speed mode" entry point) even though it has a 2 bar MAP and...

"Intake air system performance"..... any idea which parameter is most responsible for setting this on a Magna Charged '10 6.0 suburban?

I'll wait to upload the new software....

I am using the latest software (build 112) although I WAS using V2 firmware ver .28 ...... I have now updated to fw .33 . Paul, I just emailed you the error reports as well as the cal files.

Has anyone seen this?..... 2010 Camaro w/ E38, read ecm just fine, tried to reprogram but it keeps rejecting the bootloader. It says engine or vehicle speed not zero or flash memory error. Never...

Problem solved..... I think someone had been in the car and 'molested' the file, screwing up the checksum. I downloaded a stock cal from HoldenCrazy and it loaded just fine.

I just had this happen on a '07 'Vette w/ OS 24239353. Tried programming with both the old firmware (2.04.xx) and now the newest (2.06.28) in the V2. Keeps saying the same thing..... checksum...

Has anyone here converted an '02 6.0 truck to electric fans? What PCM pins did you use to wire the fan relays so the PCM could control them?

Thanks

Thanks..... I entered in values along the lines of the table in the other thread and it works great now; 14% enters PE at about 45% actual throttle.

I just found a thread that seems to address this same issue (http://forum.efilive.com/showthread.php?t=6461), but no fix was given. Has anything been found since then?

Has anybody had a problem getting the E38 to engage PE mode? I have a '07 Suburban w/ a magnacharger that I set the TP to engage PE mode at 44% @ 2000 RPM but it won't enter PE until about 70%...

We just went through this on a customer car.... shifted perfectly on the chassis dyno but flared and hit the limiter on the road during the 2-3 shift. Solution.... believe it or not.... we added 3/4...
