Loud and repetitive back firing when motorhome is under heavy load, like every time it goes up a hill. It will lose power and speed. Rarely it will back fire on flat ground. Engine starts good, idles smoothly. It accelerates great on flat ground. Had this issue for a while and it never shows a trouble code , no engine light. I have recorded many hours of data with your CRecorder and forward it to you , but nothing conclusive shows up. I have gone back to Banks to inspect exhaust and all gaskets and new muffler were installed. Catalytic converters were replaced, new fuel pump, filters.
Do you think that a factory reprograming of the TCM could help with my issue ?

Thank you, Pedro

Reprogramming the TCM will not help with the issue. Have you replaced the spark plugs and wires? Is the backfire out of the exhaust or is coming from the intake? ( Support )
I have 1999 Chevy 2500 with 7.4 vortec, can y’all look at my computer to see if someone have put a tune on it or if any of the factory tune isn’t correct? ( Dusty Parks, 10/26/2021 )
Yes, we can read out of the calibrations and compare them to stock values to see if anything is modified. ( Support )
I have a 2003 Pace Arrow/Workhorse with an 8 liter GM/Allision. The coach has a Banks performance system but best as I can tell it's only a header/cat-back system. The coach as times had gone into a disable/de-rate mode after OBD trouble codes have been set. Can you tell me if this is normal or if ECM software was modified or has a flaw? Would a reprogram do anything to help this situation? A this moment I do not have access to my vin.

Thank you!

My guess is that the code(s) you are getting have to do with the oxygen sensors. We sometimes see this issue with Banks TorqueTube headers installed and the only way we have found to cure it is to wrap the headers so that the proper amount of heat is still in the exhaust for the oxygen sensors to be happy.

I have a 2008 Safari Passage 315 on a Workhorse W18 chassis. Can you program an Electronic Brake Control Module (EBCM) for the vehicle? ( Kyle Tice, 10/12/2020 )
We only program the engine and transmission modules, the ABS module comes preprogrammed for that chassis. ( Support )
Whats the price for repair? ( Chris Clark, 10/11/2020 )
Chris, Thanks for asking, but we do not offer a repair service for this product. This is only for a factory programming of a working module. ( Support )
I bought a used TCM out of a Silverado with Allison 1000 trans. Same base part #. Can you program it for my RV?

( Dave Heinzen , 07/25/2020 )
Yes we can. ( Support )
