Hey guys,

I have a series 2 R33 with an auto box. When i pull it back to second and hold it flat, then say shift it up to third say around 5000rpm, the revs suddenly climb faster, like a surge. I dont think its "slip" because the car actually surges harder. It's really weird. And no its not the cam timing kicking in cause it will do it at lower revs too.

I have a mate with an auto series 1. It does exactly the same thing. Both boxes seem to function perfectly fine otherwise, and neither slip between gears when left in drive while holding the throttle flat through all the gears. In fact mine spins the wheels a little going into second without a shift kit. both are running around the 230rwhp mark.

Any ideas what this weird charactaristic is would be great, as i'd love to know what the hell it is?

    • Hi guys my TPS voltage is reading over 2v at idle.  My Haltech ECU is reading around 40% throttle position at idle also which is really strange. Note the actual throttle position sensor is brand new…    anyone have any experience with this or know how to calibrate it on Haltech ? 
    • The OEM disk will not work on any AEM ECU, you need to use the one they made. You shouldn't have to flip the CAS or whatever you were describing, if you set the ignition sync offset correctly it can't backfire. Make sure you're using a spark plug lead on coil 1 instead of the timing loop to avoid weird issues with the timing light. Double check that your timing settings are actually correct, like is the 24 tooth configured correct or should it actually be 12 teeth for 1 crank revolution? I also found this: 305817248-AEM-Undocumented-Settings-v1-2.pdf    
    • Yeah, I don't believe the M35 uses a deadhead system.
    • Have you done your thinking backwards? 3 bar, 43.5 psi pressure drop being the presumed specification for an injector, means you need 3 bar upstream when they are firing into atmospheric pressure, and more upstream pressure than that when on boost (you add your boost to your rail pressure to maintain 3 bar across the injector) and you need..... less pressure upstream when you have vacuum in the manifold. So, presuming that you're idling at -10 psi, then you only need ~23 psi in the rail. I realise that I did not need to say all of that to you specifically Matt, once you'd realised your mistake. It's mostly there for complete clarity for others.
    • Have you reached out to the guys at Spool Imports? They are a Ross dealer, I can imagine they would have the rings just sitting on the shelf (I could be wrong).
