has anyone adapted rb20 afm's?

do they do the same job as z32's, if so why the price diff?

the resolution is slightly different ie: the z32 can measure more air. For example for a given ammount of air flow the RB20 meter might measure 5V (maximum value) a Z32 meter might be reading 4.5V. Physically they are the same, electrially they are not. The slope gradient used to calculate the ammount of air flow for a given signal voltage is slightly different also, but the gradient is a value stored in the software of the ecu. Hope that answers your question.Paul...DIRTgarage.

standard but planning for a fc
your car is a r32 right? See lachlan riddel up there at chiptorque, he has the nissan emulator to rewrite a chip for your car and should have or could find the graident you need from an RB20 or Z32 ecu. Use this value in your rewritten chip and your afms will work as they should. We used the Z32 meters as it gave us more scope for tuning. On a mild tune road car RB20 meters should be sufficient, but i always like to only spend dollars once. Paul...DIRTgarage.

      R34 GT-T cycling ABS pump

      Lets say I wanted to buy this, specifically for this purpose. How do I actually perform the function. Can I still buy a Consult-1? Am I about to be burned by the fact my car is a 2000 model Series 2 R34 and thus will be some stupid other system? Do I just need this -> https://obd2australia.com.au/product/nissan-consult-14-pin-to-usb-ddl-diagnostic-interface-with-ftdi-ft232r-chip/ And with what software?

      That's probably OK. That's a face to face compression joint between two surfaces with the clamping load provided by those bolts. So.... it's unlikely that the bolts will end up feeling that load in shear, unless the clamping surfaces are not large enough, bolts not got enough tension on them, etc etc to prevent the two faces from moving wrt each other. Which... I would hope the designers have considered, seeing as it's probably one of the most important things the upright has to do apart from resist collapsing in its own right. But yes, it would definitely be worth asking them what their safety factor on that part of the design was. I tend to think that the casting, being a casting, is not necessarily the strongest bit of material in the world. It's about an inch square, and when you think about the loads that are being put into it, you have to wonder what safety factor the Nissan boys (and every other OEM engineer who has designed all the millions of other uprights that look essentially the same) used to account for defective casting, aging, severe impacts on the wheel, etc etc.

      Those bolts would be orders of magnitude stronger that cast aluminium though.  And its mainly clamping force, not shear they are dealing with?

      Except all that twisting force that is breaking a cast piece, appears to be going through 4 bolts in the picture Johnny posted of the BryPar one...

      R34 auto to manual conversion help

      By GTSBoy · Posted

      The smart approach is to use the gearbox loom from the manual car. Makes it a lot easier - just plugs into the switches on the box and plugs into the main loom up near the fusebox. Then you only need to deal with bypassing the inhibit switch. The other approach requires you to use the wiring diagram to identify those wires by colour and location, perhaps even indulging in a little multimeter action to trace them end to end to make sure, and then.... you will have the answers you need. The R34 wiring diagram is available on-line (no, I do not have a link to it myself - I would have to do a search if I wasn't able to go to the copy I have at home).
