Hi Guys,

ok this is a tough one. ive put my GTR injectors into my r32 rb20det. i used a resistor pack and wired it in. i have attached a drawing to show you how i did it.

so i checked everything and put it all back together, turned the key and no fire. that was with the stock ecu. i thought it wouldn't anyway but it was worth a shot. anyway i connected the (power FC) and it started first try perfect!!!!!!

runs great until it starts to warm up then it gets a massive mis and the revs rise and fall in a patten. it sounds like a washing machine.

this issue wasnt there before the changover

ive played with all the wires and plugs for both the injectors and coils.

the injectors are firing cuz i can hear them tick and when i take the coils of 1 at a time i can see the sparking

when i remove a plug, injector or coil the mis becomes constant but the problem is still there

i had the car booked in for a pfc tune saterday so i drive the car 20kms to get there. it drive fine under 3k with little to 0 knock. so i get there with the hope it the tune would fix it but no go. they tried new plugs and an ignighter and tried to dyno it to get some data but as soon a it got on boost the mis was a constant droped cylinder. sounded aweful.

the tuner said that he increased a % on number 2 injector to 80% and its helped it a bit but still a problem. he said it could be a blocked injector and to get it retested. they were tested and cleaned 2 days earlier but this could be the problem as it was hard to get the rail and new injectors into position with the top intake still on and not letting the injector touch anything else.

so guys any ideas?

i need the car for a daily all week and the tuner said i could bring it in tomorrow but if i cant fix the mis it cant be tuned. the tuner has been good to me and i know they are busy so i dont want to have them spend another 4 hours trying to find a problem before the tune.

please guys im stuck
