need some help asap!
just installed ez-tcu everything is hooked up. but the car just wants to idle a little high then choke out plus it seems to be loading up. the only thing i have unhooked is the speedo and the tcc plug for the 700 r4. the car is 88 iroc 5.7l
do i need to hook the speedo output wire from the tcu to the ecm ? i can only program it down to 4000ppm. if i hook it before the buffer will it covert it to a useable signal? any help i appreciate !
