Hey all helping a freind with his th400 swap. Making the changes to his Whipple tune and running into some issues. Mostly driveline related. OSS relocated to rear abs ring via custom bracket and pulses adjusted. Trans gear ratio adjusted. Output shaft rev/rpm adjusted. Launch assist disabled. Gear hang disabled.

Does anyone have a tune they can post to compare?
Initial problems were as follows;
DTC P0833 clutch circuit b
DTC P0573 brake switch A circuit high

Toggled these to not report and now he gets a wrench with no DTC after 4-5 drive cycles. Sometimes with an airbag light on breaking.


Any ideas?
