why do you want one?

the gauges that wire into the standard narrowband sensors might aswell be used for drink holders, dont waste your money

proper afr gauges are hooked up to a wideband sensor through a controller, these are fairly expensive, which comes back to why do you want one?

figured it wasn't just a plug and play thing...

i want one just to make sure I'm not running lean before i get to the dyno, changed to z32 afm and gonna upsize injectors before i get a new turbo. and rather than doing it all on the day and have mechanics there working on it, i'll just install the z32 and injectors beforehand.

and yes i have a NIStune ecu so it's easy to change them in the software to get the car running OK but it won't be perfect...

This is my Noobie reasoning anyway, feel free to poke holes in my plan :cheers:

The old "Brake Dyno" is great for getting your afrs (fuel table) perfect, however to make good progress on the ignition table you'll need a dyno.. The old n00b tuner ethos of "wind up the ignition till she knocks, retard it a few degrees and she'll be right" really is very overated, although plenty of jap tuners seem to get away with decent results using this method =)

tuning myself interests me alot, I'm very new to it all and it'll be a learning experience... but without a dyno how do ya really go about it properly?

I run an AEM wideband on my gtr. Had to weld a bung into the first pipe to do it for the bosch o2.

They are reasonably priced, and the controller is integrated into the gauge itself which is good. The gauge also has a 5v output to come back into a laptop for readings.

Still probably a bit wank factor-ish, but it can never harm to know that the AFR's are good when you have the foot down.

Plus it gave me something to do on a boring weekend. :cheers:

any wideband solution is going to cost $400

if its sub $100 its junk and not wideband

if you dont know what you are doing with a wideband, then stop and dont do it

you can kill your motor if you arent careful. there is lots of documentation on wideband tuning and AFR tuning so its not something new

the consequenses if you get it very wrong howver could be burnt valves = rebuild light

    • I'm actually not sure - I think it was "Stealth Performance" (It really is near impossible to find a FEMALE 1/8BSPT to 1/8NPT male at ALL) but having the thing leveraged on a 90 degree angle on a small aluminium fitting is not too smart. Also in not too smart, I've drilled out the center of the broken fitting so there's maybe 0.00001mm of thread to bite into, so yeah. I may have to get it drilled/tapped/plugged entirely. Given I could conceivably tap a thread/adapter/pressure line in any point in the oil system I suppose it's feasible to run a line to the Nissan Sensor to keep the dash working. Do these exist in AN fittings and the like? Like an AN fitting that has a NPT (or other?) thread as well for putting a sensor in?
    • I would agree.  There will be an amount of boost you could run safely with an otherwise factory system, but it would be low enough to not be worth the cost.  And if you are reliving your 20s, you know a 'little bit' was never enough. Personally, if I didn't want to spend the money, then stick with NA bolt-ons, and maybe a tune.
    • Fuark, at least the motor survived. What brand was the fitting that snapped?
    • Wrong question. There's no point in spending the rather large sum of cash and effort to add turbo, without taking it to the "sensible" limit of the motor itself. If you have to upgrade injectors, etc, then so be it. That is a tiny fraction of what it will cost you to turbo it.
    • Measure voltage at the starter solenoid terminal when the key is at start and it has clicked. If it is really low, then the suspicion falls on the ignition switch (contacts or wiring thereof) as causing a voltage drop instead of sending enough volts to throw the solenoid all the way to engage the starter itself. If it is a decent voltage, then the suspicion is on the solenoid. Might have s horted coil, or might hva dirty contacts. Rip the starter off, dismantle, clean up contacts and inspect winding. It might not be possible to see if there is a short in the winding though. I have a spare starter here that I could measure the resistance of the coil, as a guide to about what it should be, if you need a comparison. <parts hoarder>No you cannot have it.</parts hoarder>
