Marsh tuning ecu help!!!
I picked up an sr20ve swapped b13 that came with a Marsh tuning ecu, since then I added n1 cams, tri y headers and excessive manifold but I can't get a hold of him and he's to far away for me to try to go get tuned by him. My question is does anyone know the software he use to chip and tune cars or what it is chipped with. My only other plan is to send my stock b13 ecu out to either nismotronic or nistune. Any help would be grateful!!
