I am looking for exactly what needs to be done to program the vette into the Camaro tcm to allow tapshift without using the Camaro bcm. I have the tapshift box from Speartech but I am told it will also need the corvette tune to work properly. How exactly do I go about getting this tune done as I am told it has to be done with GM tech ii. Any tips on this are greatly appreciated. The only reason I am even doing tapshift is to hold it in 4th gear on the dyno so unless someone knows a way to hold in gear without manual shift we are open for any and all suggestions.
