4BT Allison Swap Tuninng
Working on a calibration for a customer using a E38 / T-14 Allison controller to inn his 2010 Silverado 4x4 5.3. He swapped to a 3.9L 4BT Cummins engine he has been working on it for a few months when he reached out to me at YAK Performance LLC. I designed him a suitable E38 based file to mimic a 3.9L Cummins engine and keep the stock ECM & truck happy. Onn top of that he used a 2011-up Allison 1000 transmission and needed a proper calibration file as well to work inline with the E38 using GM LAN coms. So far we are on the right path and I will have some logs here soon to share. I like there are people who go the extra mile and keep their stock systems in place while doing engine & transmission swaps that don't belong in this vehicle from the factory. If anyone else is thinking of doing a similar swap let me know I'm sure I can help make it a lot easier.
