2nd gear launch
 
I have 2wd, no traction at all, I need tires bad for the track. I read an article that in manual 2nd from a stop you get more traction. Anybody tried? It seemed like it grabbed more, my jump to 40 mph was quicker, to bad I did that after I left the track.

In order to start in 2nd you will need EFI Live. Manual mode will not start out it 2 if you select 2. It will only allow it to shift up to 2nd. Starting in 2nd has worked for some and not for others...it is hell on converters.

Works well for 1 or 2 passes until you roast the converter :ouch: Haha
