I have xHP Stage 3 tune installed in an upgraded Nizpro transmission. The transmission has performed very well launching in 1st gear at the drags but I would like to be able to launch in 2nd gear so as to eliminate the time lost with the 1st to 2nd gear change. On the 2 occasions that I have attempted a 2nd gear launch in M mode, the transmission automatically changes from 2nd into 3rd at around 3,500 rpm. Is there any way of stopping this from occurring? Log of last attempt is below. Somehow achieved a 11.159s @ 128mph on this run.
