    Rpm / Load Cut At 3000 - 4000 On Rb25Det

    in Forced Induction Performance

    Posted · Edited by guricha

    I already change maf to Z32 and fuel pump is 044, as i mentioned boost is the standard and dyno showed somewhere 5 psi at the moment of cutting

    DTC flags i already play with :) i think disable or enable them is only giving that errors not comes up and that is all

    Really strange thing is that car runs at really lean unless i dont play with Constant , it should not be! after changing the Maf constant goes from 3xx to 560 and that value is terrible lean unless i dont go to 640 to make at idle close to 14.1 -5

    Also as soon i will go from neutral to any gear car goes to knock Map

    what about cas? if its wired right should it have this issue anyway ? maybe the signal is different voltage ?

    On S1 is mitsubishi cas system and on later one is Hitachi, i have checked cas discos and there is almost no difference, anyway some guys have succeed same swaps with no issue, but looking at google i found threads where people got this issue on stock car but couldn't find reason

    Hi guys

    I have really strange problem on my car, was searching for answers through Google but found only questions.

    Here is the deal:

    I bought R34 with RB20DE and manual gear box,

    engine was swapped with RB25DET from R33 series one

    wiring i didnot change coz i had no wiring loom from r33 with ABS so i decide to adapt R34 wiring to R33 engine, was needed some adaptation especially with cas and few more sensors

    ecu is used from R34 gtt with nistune board inside

    Car has the problem, during the acceleration with load it has fuel or load cut at 3000-4000 rpm, cut mostly looks like RPM limit

    Dont know where to find problem, change everything few sensors maf even fuel pump, took the car on dyno to measure boost and its standard, i mean car cuts at 5 psi of boost, boost leaks, spark plugs, gap and timing, all this procedure i have done but no success

    Maybe anyone had similar problem during the swapping rb?

    only thing i have left is change cas, they are different type on r34 and r33 s1, that will be hard and easiest is to change wiring to r33 and run on Z32 ECU, but am not sure that this can help, found over the net same problems and nobody writes how they fix the problem or what was the reason

    Ah and yes cuts at different rpm depending how the ignition is set

    thanks in advanced and looking for some help
