Hey guys, i am currently finishing up on a R33 RB25DE conversion on my R32 GTS-T. The only part missing now is the AFM, i've heard that people with moderate modifications use the Z32 AFM, so what does a normal, stock R33 RB25DE use? Can i get this from a wrecker or do i have to buy it new? Thanks. My uncle who is helping me with the conversion says that the R32 RB20DET airbox and AFM is different to the R33 one.

you won't get the z32 ecu to work properly without a piggyback computer of some sort (or full ecu) to change the settings. the z32 is the same size as the rb20 and rb25 afms and works between the same voltages but reads different voltages at different airflow rates to the stock afm.

you can use the rb20 afm on a series 1 rb25, but to use it on a series 2 you need to play around with the wiring (not very hard, think it is only 1 wire different)

you didn't really read what i said did you? there are 2 different types of r33 afm. if the rb25 came out of a series 1 r33 then you can use the rb20 one as it is the same. if the r33 was a series 2 then you will need to make sure you get a series 2 afm, or you can change the wiring to get the s1/rb20 one to fit.

      Diagnosing with and without is mostly the same. You need to know, as Duncan asked, and what conditions. Car hot, cold, idling, driving, if while driving what rpms, is when you're varying, or is it when held constant.   From there it's understanding what can be causing it. Starting with pretending all of the sensors are correct. Which means if it's going rich, why would it be thinking more air is going in than it is, and under what conditions. So things like if only when under boost, it could be be a loose intake piping joint. It's just understanding the system, and understanding when/how the problem occurs, and then if it's only occuring in specific scenarios, what can be causing it.   ECU specifically, if it's aftermarket, it'll have software you can use, for the Skylines on factory ECU, there is Nissan Consult you can use. Most ECUs have a way to get data from them.

      How do you go about diagnosing ecu's that don't have data logging, is it more experience at that point and just trying out things that you think will fix the issue?

      Stock O2 are basically useless beyond anything at stoich. Any misfire will also be seen as lean. The stock O2 also read a collective exhaust gas volume, not each cylinder. Sputtering and missing means not each cycle is firing, and some are. Which means even if rich, as shit, on cylinders as they miss, they'll read lean, but the cylinders that did fire will read rich, and combined, well, they can read anything from rich to lean.   Start with the basics before even going looking at sensor values.   Edit: I say the above, and that's coming from the guy with a few thousand dollars worth of scan tools sitting right beside me right now that I use frequently for my job.

      I just finished up a manual swap and I have a 1999 S2 AWD automatic in my garage, depending on where you are located. I'm in the the midwest of the US.

      I’ve heard it can be done, you need to redrill the holes where they bolt to the chassis and apart from that they are the same. I’ve never done it or know anyone personally that has, it’s just something I’ve heard
