like in title. Is speed signal is important to ECU to run correct ?
I have RB25DET in S13.. As you know speed signal is from gearbox, next to speedometer and than to ECU. But speed signal from rb25det transmission is different than from s13 gearbox. So ECU don't have correct info about speed of the car. Is it possible that car don't run so good as he could when speed signal is good ?

Thanks a lot for answers

Yes, many ECU's use it for when slowing down (when car slows - mainly engine braking, it cuts the injectors to save fuel. When slow enough they cut back in)
