odd...
we have a sk2 ecu from a previous engine that blew up due to poor building by the people they bought it from...
he has falken drag street radials too so he is getting good starts...
seems like vtec doesnt always stay in since its set around 5500 or so...needa lower that to bout 4400 and hopefully that will help
btw: tell ur buddy to sell his mugen ecu, i hear they are very good compared to other ecu reprograms...dont get me wrong tho i love mugen just not there ecu's....
were also puttin a new vtec syliniod on the engine which is mugen, it should kick real hard into vtec...
