Personally, I am going with the SAFC 11 current version, for ~$400 this gives a good A/F ratio result. You can't play with ignition as the auto needs ignition retard to give smooth shifts and not overload the transmission with torque while changing gear (prolongs gearbox life). So looking at other options with ignition control capablity (EManage for example) is a waste of money.

Full ecu upgrades, Power FC for example, aren't on the cards for me as they have no programming for the auto. Sure they run the engine itself just fine, but not the auto for the reasons above.

I am looking at around 200 awkw (that's about double the standard kw) and I have seen plenty of SAFC's work perfectly well at that power level on other RB25DET's. So the decision is pretty easy for me.

Hope that helps:cheers:

do a plug in board to allow remaping a r34 rb25 neo

anyone know if its the same ecu in the neo equiped stagea's ?

what about the hardcore aftermarket ecu's like motec and autronic ? I have seen autronics control auto sr20s before .

Nope, they have no shift logic. What you can do is use one of their outputs to change gear. Stuff like at 60 kph change into second, at 120 kph change into third etc. This is OK for a drag car, but not realy "shift logic". Where you want smooth up and down changes, down hill, up hill, under load, cruising etc etc

I was told that the lines of code to get an auto to changes gears properly, all the time, was over 1,000 times more than that used to get the engine to run. That's why you can buy manual car ECU's easily, but very very few auto ECU's. In fact the only one I have seen is the Power FC for Toyota Chasers and my understanding is it has Toyota auto shift programming anyway.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.

      Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
