Hi guys, I have the 16s, on a SOHC rb30. I was just wondering, can the microtech be easily set so that if the ecu is powered but ignition is on, the fuel pumps will only prime for a set amount of time? Would be much nicer to just have the computer control this than have to have a seperate relay and timer. Essentially all I want is to turn the car onto accessory, have the fuel pumps prime for 6 seconds, then stop, until the car is started. I have the book somewhere, but I cant locate it at this hour. Cheers, Jack

That's already what the Microtech should be doing - prime the pumps for 5-6s then stop

It should be doing they already. How have you wired the pump/s?

I'll have to double check, I'm currently rewiring the boot stuff now because I wasnt happy with it. Power directly off battery, goes into 30A fuse. then goes to relays in the boot.

Yeah good, then the fuel pump trigger from the Ecu triggers the relays?? If so then they should be turning off pending the relays are wired correctly/the right type. I have never looked at a microtech program but there should be a setting for how long the pumps prime for.

awesome, thats exactly what I wanted to hear. I havent had a chance to prime them up to double check will wire them up tomorrow to make sure it's all good.

I thought with the microtech it only primed the pumps when the ignition was switched to on? Not accessories?

accesories is backwards isnt it? so youd be right troyvk, my lt10's primes for like 20-25 seconds. so it does stop but primes for quite awhile

mine primed from accessories IIRC. Just not sure on the time it took, will have to double check

it depends how the microtech is powered, it's pretty simple as soon as the microtech sees 12v it will prime the pumps for a pre determined time after this it will only supply a signal via the fuel pump trigger if it sees a crank signal from memory it is the pastel green or light green for the fuel pump trigger

for the 16s I had a look at the book and there are all different things that sound like they could be what I want, does anyone know what setting it's actually under? I'm assuming the system has been wired as recommended by microtech... Mine seems to prime for as long as it feels like at the moment, but usually it's about 10 seconds.
