Hey Guys,

I recently read out an ECM, and it is giving me a Checksum error. Is there anyway this can be fixed other than reflashed the ECM to a stock file and starting over? It will save me a lot...

Email sent.. Thank you.

Yes it is an E38. When is the next release? (I won't hold you to an exact date) Thanks.

I believe the OS ID is 12644905. The trans is the Allison based 6 speed HD for gas vehicles. Let me know if this helps. Thank you Taz.

Hey guys,

Is there any support at the time for this? I recently tried to read the PCM, and it won't read yet, but I was wondering if there is a possible update for it. It's very similar to some of...

Check your pm. Thanks for the help man.

No one? Maybe someone can help with this problem which I believe is paralleled with the readiness. I can'r run the O2 testing in the scanner. It says it does not communicate with the ECM. Is there...

I have been tuning an E38 ecm on a Chevy Express van, and I am trying to get all readiness codes to come on and a few just aren't. Is there a way to force readiness or some kind of drive cycle anyone...

My apologies. E78 ECM on a 6.0L silverado hd. Thanks.

Perhaps someone can shed some light on this issue. If I come to a stop and let the truck idle for about 20-30 seconds the motor has a slight stumble and through the datalog I can see PCM demanding...

Hello Ross,

Is it to early to expect any updates? Thanks again.

Hello Ross,

Any updates? Thank you.

Hello Ross,

This is a 2011 truck I am doing some work on. All these tables are for a non standard tuning project. The truck has trouble starting and has some surging issues because of the cranking...

Hello Ross,

Thank you for the explanation. I wasn't even expecting the tables that are available to be as similar as they are. I need an update on cranking fuel, open loop IVT gain, open loop...

Hello again Ross. Thank you so much for the help. It seems like the links are not working. Is there somewhere else I can download these? Thank you.

Hello Ross. Can I email you a few tables that you can possible add? I know it might be asking much, but it would be nice to have the same control as we do with the E38 ECM's. I see many spark and...

no one huh?

I was hoping someone can shed some light on how I can switch some of the readiness codes to "Not Supported or N/A" on an E38 ECM. I noticed I have the option on the E78 systems but not on the E38. Is...

Thanks Ross. I got it to work last after doing some more work with it. One more question on the tuning end. I don't see a cranking fuel table defined. Is this something efi live will be adding for...

Hey guys, I am trying to Read the PCM, and I don't see the E78 listed. Do I need some sort of upgrade? Thanks again for the help.
