Hey guys,

My 97 C34 Stagea RS4 auto was going fine, only averaging 15L/100kms city driving but still ok. Planning on doing the O2 Sensor.

I wired in a SAFC (the first style series 1 safc) and the car now has issues with anything over 2800rpm and more than 50% throttle.

I have wired these in to various cars a heap of times with no troubles.

I used a wideband O2 sensor to check the afr and it jumps from 10.0 - 12.2 whilst surging. (this is with the Safc settings all on Zero)

I also noticed some pinging around 5000rpm.

I assume the SAFC is faulty... Anyone have other Ideas???

I guess the options are

1. Its faulty

2. Your car has coincidentally developed a new problem

3. one or more connections are incorrect or you haven't set the tabs right for the Stagea

4. one or more connections are bad (loose etc)

If you don't already have it I have the SAFC manual as a word file or the ecu pinout if you need that.

Ok just fixed the problem, but who knows how long it will last.

Re-initialise and re enter all settings etc for sensor type etc and it's fixed!!! Im guessing it is a faulty unit...

You really need to adjust your timing as well. Here's the link in case Juzzy.melb doesn't buy it:

      Pipe from Greddy FMIC to Greddy intake manifold (RB25)?

      Does anyone sell a pipe that's made to go from the Greddy FMIC kit for ECR33 (RB25DET) to the Greddy intake manifold?

      Not that I know from experience, but in theory you'd want your gate spring to be as close to target pressure as possible, so you'd go with the higher gate spring?

      Before I commit to it as I already have the wastegate off the car, would you change it to the 9psi spring instead of the 12, or whack it back on now and try your suggestion?   Edit: Actually I might just swap the spring and see what the logs say after another few pulls, as we know it's still spiking without the Mac valve in the picture so I need more data without the Mac valve trying to combat the issue.

      Sounds good Hmm suppose the main thing is, how much do you care about this car? The filler doesn't make for a very good water barrier lol. If there was a tiny little bit of rust forming now, that in 3 to 5 years time becomes obvious under the paint (starts to bubble up), would it bother you?

      Mistakes were made, my R34 Story

      I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.
