lately my 33 gtr is down on power and splutters everytime i put my foot more than 1/4 throttle. it hunts up and down on idle and even stalls. So i hooked up nissan datascan and it came up with error code 12 everytime i started the car, which is bad AFM connection it says. i re-soldered the AFM'S but still doing the same thing. Anyway im about to buy a set of rb26 AFM's and hope it fixes it. However I just want to confirm the voltage an r33 GTR afm runs as nissan datascan says mine are .95 volts on idle. Also my o2 sensors seem to be buggeed as the reading just keeps goin up and down, but i dont think it would cause such eratic behaviour would it? just stupid fuel consumption.

make sure there are no air leaks after the AFMeters, it will cause the exaxt same problems

Hey mate, check my thread on here about a similar issue, I re-soldered my top AFM and it came good then started up again - I assume the AFM is shagged so testing a known working one today. I'll let you know how I go but I suspect your problem is the same as mine.

Could you PM me details of this Nissan Datascan setup you have?

Cheers

      Wiring high beams in IC7 for R32 GTR

      It's not a dumb question. I was circling this idea myself. User error is always possible!

      R32 gtst speedo out by 10kph

      Nope. The seal is in the drive. A new cable would just fill up and continue to convey oil to the speedo head. To check if this is what is happening, take the cluster out, dismantle the speedo and have a look. You probably don't even have to dismantle it. If there is oil coming up the cable, the drive into the speedo will be grossly greasy. I had to manually (and delicately) clean the gunk out of my speedo.

      Thanks for the quick response mate, and I agree Nismo 555s, Z32 and high flow 2871 in OP6 housing (run by PowerFC) would all be "period correct" and should be a simple, reliable and reasonably quick track car.

      It is normal for a speedo to read 0-10% high (unfortunately), intended by manufacturers and ADRs (although not in this case) to ensure your speedo does not read low if your tyres are worn. Speaking of which, what size tyres do you have on the rear, and what does they tyre placard say you should have? you can use this https://tiresize.com/calculator/ to determine what % difference that is causing Personally, when I buy tyres for a car I buy a size that will bring the speedo back to being more accurate; it if it reads 5% high I buy tyres that are 5% larger diameter. If you had an electronic speed sender like R33 onwards, the other option is to add a speedo adjuster but that won't work in R32. Finally, you  might be able to find a different sized gear for the speedo sender but that will be limited to what already exists (and I don't know what sizes do)

      OK...so dumb question to check....do the hi beams actually come on when the push the stalk to engage them (keeping in mind your headlight switch must be at ON as well)
