Uggg, V1 is a dinosaure. It dosn’t matter if you use it on a OMG 2JZ with over night parts form japan flap flap… or a soybean feild drainage pump 7hp motor. Ya it “works” but have fun tuning desent sized inj’s on a boosted car on the 24x24 resolution tables. The current board has options that will pay for the added cost easily. Shift light, 2step, meth/N20 contoal in RPM or boost windows, boost controal, N20 bottle heater contaol. Tons of stuff still in beta that freewear. v3 board is a steal.
