Hi guys and gals,

just a quick question after installing an apexi pen style turbo timer and was wondering if anyone knew how to program the O2 and AFR part of the timer as the instructions with the timer aren't that clear. any help would be great. ps its for a series 1 r33 gts-t 94 model.

cheers chris

There is no programming. It's as simple as getting a pinout diagram of the ECU and then tapping into those respective outputs.

You don't need one. Uninstall it and buy something useful.

This. Listen to it. I have one and I dislike it immensely. Used to think it was cool and that everyone thought I was badass. My have even thought it served some remote purpose. But it's not, nobody does, and it doesn't. They are just annoying and they cause problems. If I could be bothered ripping it out then I would, but it's no longer working anyway so I just leave it there.

Mine is generally switched off in most cases but is mounted right up in the upper right of the windscreen, nobody see's it and its of no bother :) Most trips in the car wouldnt warrant having it on...

ok from what im gathering the af and O2 function are just wank, set the timer and be done with it! cheers thanks guys.

Martin, i spliced into the loom at the right connector just doesnt want to work. just wondering if my o2 sensor is shot because the autometer guage never reads accurately as well.

any way thanks for the info and feedback gents.

Is the Autometer a wideband? If not, then it will never read accurately. If it is, then that's why the O2 sensor function won't work, they only work with the stock narrowband signal.

martin its a narrow band guage but its never raed accuarately only maybe once or twice in its life. i also connected the apexi time directly to the o2 sensor loom in the engine bay and went for a fang never got above .5v which makes me start to think the sensor may be stufed. the motor does have over 320K on the clock. but still pulls hard and drives well. whats the average life span of an o2 sensor anyway? any help would be greatly apperciated.

Well what do you consider accurate? The only thing a narrowband gauge will ever do is flick from lean to rich. Off the top of my head, the sensors operate between 0.4v and 0.8v; but will typically be at around 0.45v. If it's not showing over 0.5v, you may have a stuffed sensor, or the gauge you are using is junk, which wouldn't surprise me.

If you are getting any semblance of decent fuel economy, then it won't be a stuffed sensor.

car still gets around 550km if nursed or around 400km if flogged per tank. only has rebuilt turbo (roller bearing and steel ex turbine and blitz nur cat back exhaust. so i guess i just got sucked in by the techno wank factor :rant:

:cheers: cheers thanks for the help

Dont install it man, just dont flog it for 10mins before you turn it off, there the biggest wank factor out and it makes your car ALOT easier to steal.

Even 10 minutes is a lot of overkill. 1 minute is plenty.

      S1 rb25/s14 starting problem

      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).

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      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?
