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 headlights?

      By Duncan 路 Posted

      It might be worth having a good look at the chassis behind the bumper then; most people prefer the series 2 look so it might have been changed to cheaper parts as part of an earlier repair

      The car itself a series 2. I was just curious about the headlights and just wanted to confirm that they were series 1. Good to know the rest of the front end is series 1. It鈥檒l be easier for me to find parts on the aftermarket side of things lol

      If you've wired up the coils & injectors properly, & have the neo CAS loom for the trigger, it should all work. The VCT works the same way so just different plugs between s1 & neo. Assuming DBW if no IAC. Don't bother with the stock boost solenoid with g4x.

      THERE IS NO IAT SENSOR ON ANY SINGLE TURBO RB. And the one on an RB26 is not for "engine control" - it's really too big and too slow and is only used for over-temp alarming (as far as I can tell). Anyway, you don't have one. You want/need one for the Link, then you need to buy one, find a spot for it, and wire it in. You do know that the stock boost solenoid is not capable of "control", right? It is merely on or off, for the low boost (5 psi) and high boost (7psi), which the ECU enforces mostly based on gear. The stock solenoid is not for PWM control and is not plumbed up in a way to provide it. If you want to control boost properly, then you need a proper MAC valve. And yes, you can wire either of them direct to the ECU. Well, I assume you can - I don't know what the boost solenoid pins on the plug and play Link are capable of. They really should be as capable as any normal Link - but seeing as it is plg and play, it might be limited to stock functionality. Read the doco.   You really do just want to plug stuff together without understanding how it works, right? I can't help you there. I don't know the plug types or pinning on half the stuff you're asking about. If I had to do it I would sit down with the wiring diagrams, the car/looms and a multimeter and work out what is what.
