Hello there ....i realise that this is an old threat,but i really need som help : S
i just installed a Apexi Full Auto Turbo Timer on my S13.all wires are correctly installed but i have a problem.when i turn the ignition switch off the timer starts
the countdown and when it reaches at 0 sec the timer starts all over again.so my engine wont turn off.i've tried everything i could think of.
if anyone knows the solution!!oooh also the A/F doesnt work.the red led just keeps flashing.the 02 cable is correcly installed in the ECU.
every thing is connected as it supposed to be. btw i swapped to a RB25 dont know if thath helps..
Thanks alot
