i bought a fully Built gsr motor that my friend built. Its very high 12 5 1 compression and I havent tuned it yet. I am currently running a chipped p72 ecu but i dont know anything bout honda tunning. Can i just get a wideband and get away with using a stock p72. Or do i have to use another type ecu? Its bored out to 84.5 mm just below 2 liters do i have to get b20 map or what shpuld i do im not familar at all just want to get the motor running stochiometric when i put the cams i got for it in? anywhere like a website to learn bout honda tunning. esp do it urself
