Hey guys, glad to become a new member of skylines australia. I have a S14 with a RB25DET series II motor. I have alot of questions about the Apexi Power FC. My mods pertaining to the Power FC are: 90mm Q45 throttle body, 90mm Ford Lightning MAF, and 740cc Tomei injectors. I saw paulR33's FAQ post and figured the values for the injectors would be as follows: 370cc/740cc = .5 * 100 = 50% and

0.66ms - 0.53ms = 0.13ms. Would these be the correct values for the injectors? Also, would I use 90mm Q45 setting for the MAF or would I need to go under options and select a voltage? I have a Ford Lightning 90mm MAF and I am currently using the setting for the 90mm Q45 MAF. Before I bought the Power FC, I was using a Jim Wolf Technology reflash as my tune. This tune required me to set my timing on the Cam Angle Sensor to 20 degrees BTDC (before top dead center). Do I need to set anything in the Power FC to correspond to this or do I need to change the timing on the CAS? I also have a Apexi SAFC installed along with the Power FC. Do I need to unhook the SAFC, in order for the Power FC to operate properly? I checked pin #58 with a test light and it is ok. I also disabled the optional boost feature on the Power FC. When I try and start the car, it tries to start but stumbles after 2-3 seconds. All I want to be able to do is get the car to crank so it can self learn the idle. After that I am going to Balanced Performance in Sugar Hill, GA to have it tuned. Anyone ever heard of them by the way? The car was running fine with the Jim Wolf Technology reflash tune. When I disconnect the Power Fc and re-install the Jim Wolf ECU it cranks right up. Please guys help me out with this. I know it is probably something simple. I called Apexi and they said that using both the SAFC and Power FC should be ok, but that I would not need the SAFC because the Power FC does everything it does and more. Anyways, I cannot think of anything else to tell you about my problem, so thanks in advance for any advice it is greatly appreciated.

Thanks,

Chad

      PRP RB26 cast block + head prototype running

      By GTSBoy · Posted

      Well, yeah, the RB26 is definitely that far off the mark. From a pure technology point of view it is closer to the engines of the 60s than it is to the engines of the last 10 years. There is absolutely nothing special about an RB26 that wasn't present in engines going all the way back to the 60s, except probably the four valve head. The bottom end is just bog standard Japanese stuff. The head is nothing special. Celicas in the 70s were the same thing, in 4cyl 2 valve form. The ITBs are nothing special when you consider that the same Celicas had twin Solexes on them, and so had throttle plates in the exact same place. There's no variable valve timing, no variable inlet manifold, which even other RBs had either before the 26 came out or shortly afterward. The ECU is pretty rude and crude. The only things it has going for it are that the physical structure was pretty bloody tough for a mass produced engine, the twin-turbos and ITBs made for a bit of uniqueness against the competition (and even Toyota were ahead on the twin turbs thing, weren't they?) and the electronic controls and measuring devices (ie, AFMs, CAS, etc) were good enough to make it run well. Oh, and it sounds better than almost anything else, ever. The VR38 is absolutely halfway between the RB generation and the current generation, so it definitely has a massive increase in the sophistication of the electronics, allowing for a lot more dynamic optimisation of mapping. Then there's things like metal treatments and other coatings on things, adoption of variable cam stuff, and a bunch of other little improvements that mean it has to be a better thing than the RB26. But I otherwise agree with you that it is approximately the same thing as a 26. But, skip forward another 10 years from that engine and then the things that I mentioned in previous post come out to play. High compression, massively sophisticated computers, direct injection, clever measuring sensors, etc etc. They are the real difference between trying to make big power with a 26 and trying to make big power with a S/B50/54 (or whatever the preferred BMW engine of the week is).

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      Is the RB26 actually that far off the mark? Honestly from where I'm sitting a VR38DETT is not actually that much more advanced than the RB26. Yes, there is a scavenge pump on the VR38, it's smarter in a number of ways but it's not actually jumping out to me as alien technology. Something like a B58 or V35A-FTS on the other hand has so many surprising little design features that add up to be something that just isn't comparable.
