R33 Gtr Powerfc In R33 Gtst Almost Finished

Recommended Posts

i have a r33 gtr power fc in a r33 gtst the car starts but shots right off. on the handle held controller there is only one error. the air temp sensor is not wired in yet.

I think the problem might be coming from the injectors that i have.

I'm using sard 800cc high impedance 1.60ms lag time. I'm not using a gtr resistor pack on the injectors can this be my problem.?

Or do i need low impedance injectors.?

this is the link to the injectors that i got

any thoughts would be helpful.

thanks mate.

check the AFM voltage in sensors check. it should give you a reading even with the engine not running.. if its not working it can cause this.

thanks mate checked and both are at 0.48 i guess this would be mv.

i had the car running on a gtst power fc before and it worked well i'm just checking to see if i can get it to work as good as a power fc for a gtst i will have to use a custom trigger switch for the vtc control.

has anyone done this before? is it possible paul did pritty good he shouldnt stop i'm trying to finish what he started pauls work realy helped me in this process. thank mate.

the mafia (jono) got it working and he did a video of his car driving around

when i did it on mine i had issues with the fuel pump control

as soon as the PFC had power and car was set to ON the pump pump control would constantly reset

so the pump would re-prime approx every second, so it would fire and pass diag, but reset the fuel pump and re-prime

i suspect this is what is happening with yours. cubes and the mafia are the best to speak to. cubes (joel) was pretty cluely on why the fuel pump would -re-prime constantly. check the Fuel PCM wiring etc, i think when you go from BCNR33 to ECR33 the wires are flipped etc?

yeah its quite common, we do a few.I prefer to use the d-jetro though. There are a few guys on here we did it for so you should have no dramas nutting it out.

OK i check the fuel system its seems to be working the same way with the gtst power fc is. i would turn the ignition on the on position and the pump would prime for like about 2 -3 seconds and shut off. Now when i crank the key the pump would run. to eliminate all doubt i hooked the pump up to a switch and turned it on when i wanted. and the car still starts and cuts right off.

with the engine off the sensor check shows me 0.48 for number 1 and 2 afm's this i think is working fine.

I really do think its something do do with the injectors.

Will the car run with high impedance injectors 1.60 lag. with a resistor pack from the gtr.?

does any one know the final ohms that a r33 gtr power fc will be Happy with.

444cc/800= 0.555*100= 55.5% new correction input for power fc.

1.60 - 0.772 =0.828 new latency

everything seems to be in rang here. any more thoughts would help mate.

    • The two diagrams are equivalent. The R32 one is just one sheet out of about 3 showing everything in the whole car all at once. And without knowing the functionality that occurs in the modules, they are both equally opaque.
    • 8v - 2.48ms 9v - 2.15ms 10v - 1.74ms 11v - 1.41ms 12v - 1.15ms 13v - 0.99ms 14v - 0.89ms 15v - 0.82ms 16v - 0.81ms I'm running these values on my RB20 Neo with 570cc Denso R35 stock jets and it's great. Also bought a set for my Legnum VR4, love these injectors!
    • Thanks for your reply,  Those blue/green wires running to the actuator aren't attached to anything, so I'm not sure how the central locking is still working. I will have to take a good look tomorrow, I don't have the car with me. After googling it seems like a pretty common aftermarket actuator which even uses the same green/blue wires the immobiliser required. i'll test everything tomorrow and if it's working i'll melt the solder, strip it, resolder and neaten it all up with some heat shrink. I don't have to understand it if it works hahaha I just don't want a fire/ short circuit. That R32 diagram looks more like a continuity chart? Can you make sense of this form the R34 manual? 10V is probably due to very flat battery, i'll recheck as well tomorrow, I did have to jump start it haha. Thanks again!  
    • So, COM doesn't mean comms. It means common. What common itself means will depend on the type of device. For a two directional actuator (ie, one that can push and pull on the same output rod) then the common will typically just be the earth connection. There will be at least 2 other wires. If you put 12V on one of the other wires, then the actuator will push. On the other 12V wire, it will pull. Can't quite make out what is going on with the wiring of your actuator. It appears to have several wires at the actuator plug, but there only appears to be 2 wires where its loom approaches the door control module, with at least one of the others cut off. I don't know these actuators off by heart. I'd have to look at a wiring diagram for one before knowing what the wires were about, and that's despite me having to replace one in my car not all that long ago. Just not interesting enough to have dedicated memory set aside for trivia like that any more. That actuator is an aftermarket one, not the original one, which probably died and was replaced. That might require some sort of bodge job on wiring to make it work. Although nothing should justify the bodginess of the bodge job done. As to the soldering job on the door module's loom plug. Ahhahhahaha. Yes, very nasty. Again, I cant tell you what any of those wires do. You'd need to study the R34 wiring diagram (if you can find one that shows the door module). I don't think I have any. I'd have to study the R32 diagram to start to understand what mine is doing, and again, even though I've had a problem with mine for the last 25 years (where it locks the passenger door when the driver's window reaches top or bottom of travel) I'm just not interested enough to try to to work it out. So long as it's not burning down, it's fine with me. Here's the R32 GTR diagram, which, confusingly, has rear door lock actuators and window motors on it!! As you can see, unless you understand the functions of the door lock timer and the power window amplifier, you'll never be able to work out how it works just from the diagram. I don't imagine that the R34 one is any better. Hopefully an R34 aware bod can help. FWIW, the two wires that are cut and joined look like they are both power supply - so hopefully it is not fatal to join them. The 10V you measured on the cut off free end of one of them is concerning. You'd expect 12V, and it might be the reason for the bodge job joining them together.
