Finishing up my LS/4l60e swap into my 1978 Ford Bronco. Ran it on the dyno and was happy with where it was at. Took it out to do some real world driving and it goes into limp mode on hard acceleration/WOT from 2nd to 3rd gear. Ive posted the tune and log. At a loss on why its going into limp mode. Never went into limp on dyno during WOT runs, but trans was locked into 3rd. Thanks78' bronco driving tune trans update 12-1 20 degree 1-22-24.hptbronco 3rd drive limp mode.hpl
