Hey guys,

ive have a Apexi Afc neo lying around the house that used to be used in my soarer, question i have is it worthwhile installing into the GTR? is it even possible as the rb26 runs 2 afms?

my car is relatively stock (turbo back exhaust) and don't plan on major mods, so i don't justify shaking out a $1k for a PFC.

not looking for major power gains just a bit more response/torque maybe some economy on the way.

any input would be great?

Waste of tiime imo...

To me the gtr ecu is lean as is until very high up in the rev range so economy is probably as good as it gets with no direct control over timing, and timing is where its at if you want more response/torque..

Remember the afc affects fueling by altering the air flow signal and it changes timing indirectly....most times opposite of where you would want it to be so its a balancing act and gains if any would be minimal

Its works ok for the 25det guys with minor mods trying to get rid of r&r but on the 26 its basically worthless

With that said i have a safc2 on my 26 along side a pfc but its sole purpose is to act as a 2nd knock dectecting device...a feature the neo doesnt have

So unless if you just want a pretty colourful screen on your dash ditch it and get a pfc

sif, nistune supplied fitted and tuned for under 1k, power fc 1k to buy then tuning :)

You'd need to get 32 GTR ECU on top of that.

Unless there's Nistune board for 33 GTR available?

If any of your mates have a wideband, hook it up to your rear exhaust take it for a ride, if the A/F are decent don't bother with anything. Just enjoy the car the way it is.

    • When you crank your car, and hit it with a timing light, can you see a steady crank timing?
    • Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).    
    • Car is on factory injectors/z32 maf/ q45 throttle body/ z32 ecu with nistune 
    • Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov
    • yeah I was shocked when I checked my spare OEM on and as below that's how they come from Nissan. (side interesting note new NEO gearbox and replacement park lack the brass bush on the tips and its just all alloy) unsure about damage to the box currently back at 1110 to be pulled down/inspected and selector fork replaced as he built it previously and given the never before seen failure on his billet forks he is replacing it under warranty. He said he has used always OEM the keyway tab without issue for years so it could be an unlucky coincidence. I did talk to him about the sharp corners and stress concentration too. Re: hard shifts i got 7+ years out of the OEM one and the fork itself failed not the keyway. so could be bad luck as I said or an age thing + heat cycles in box and during fabrication of billet?
