    • Vi-PEC V88 plug & play E46 M3 MS54 standalone ECU available through Apex Speed Tech

      Apex Speed Tech has announced a plug and play S54 ECU kit utilizing the Vi-PEC V88 is available for $3400. This includes a complete plug and play harness. The ECU has dual map capability which means pump and race tunes at the flip of a switch. It also supports the E46 traction control. Apex Speed Tech is claiming they have used this ECU successfully in everything from road racing to 1200 whp twin turbo setups. We haven't seen these twin turbo setups personally or any details of to support that claim but this plug and play ECU should open up the S54 to some interesting custom setups as well as a variety of swaps.

        Exactly, the dme is complicated and there doesnt seem to be a lot of work arounds. Going aftermarket standalone is also costly because of the custom wiring.
        If the wire harness are the same for all s54s then the Vipec could be really helpful or at least minimize install costs.
        Obviously not sure how much other electrical functionality would be lost by ditching the dme in a z4 compared to a m3. Doubt ill be the one to test it though lol

        Thanks

        I have been an engineer in the AMA Superbike paddock for over 5 years now. I have worked with Rockwall, Erion and the Honda Factory, now I am the electronics engineer for Michael Jordan Motorsports. In my career I have handled engine tuning for Jake Zemke, Aaron Yates, Geoff May, Aaron Gobert and a variety of other riders. My current engineering staff probably has more combined AMA wins and championships than anyone in the paddock. I have worked extensively with both Geoff May (Buell) and Jake Zemke (Suzuki) ; I can say with confidence my example was relevant and the comparison is not laughable at this level.

        So from my perspective, the Buell and the Suzuki are actually quite competitive on certain tracks; I am confident that results would have been quite similar if any of the top 5 riders were on that machine. Does that mean chassis and rider wasn't some of it? Of course not. But those factors alone, in this case, do not make up for the 25%+ power difference. Without going into a lot of detail in my example, I was saying that the power characteristics of the two motors was more significant than the peak power numbers, even when taking into account chassis & riders.

        Back on topic though, I find dyno charts unreliable in evaluating an engine management system. If there is a significant difference between two systems, the one making lower power has serious installation or setup issues and should not even be considered.

        Well, all I know is Geoff May on his Buell finished 11th in the superbike standings. He is the highest Buell and his best finish is 6th @ Barber. Seven of the bikes above him in the standings are GSXR 1000's & all but one are Japanese 4 cyl. bikes. Would Josh Hayes & Tommy Hayden still be on top if they were riding Buells? You seem to think maybe, I kinda doubt it, and we will actually never know, but anything is possible & you certainly know more about it than I do. I know I would love to see the top 5 guys try each bike at each track to see how they stack up, but it's not likely to happen.

        So, I take, this unit may be a good choice for a 600 whp SC set up, yes?

        But what about for a street car?

        Our policy is we do not support OBDII compliance, and any kits we sell are for off-road use. We can (and have for other markets) built piggyback systems that work excellent for street cars. We do many pre obdII swaps that run great on the street. However, for an OBDII E46 intallation the check engine light, EML light, Rev limit lights are all on and cruise control won't work. There are people who can reflash the stock ECUs to deal with the the warning light issues.

        So for example, can an S54 swap be done as OBDI?

        Well, the only way to make something OBDI from a legal point of view is to certify them. But if by OBDI you mean the swap will integrate with the stock vehicle wiring, control the check engine light and allow the car to pass a tailpipe sniffer, yes.

        Neel, is this all? That sounds completely reasonable for street cars that won't require emissions testing.

        Yes, but when he says they won't work does that mean they will be on looking like a Christmas tree or simply not functioning?

        I think the answer depends a fair bit on the car.
        A white 335i will be far from fully functional at a self diagnostic level, but a black bnr32 will have 100% of stock look and function.

        I'm sure you are already aware of this but still worth a look for a Z4 M owner: http://www.bimmerboost.com/showthrea...5477#post65477

        The eml, check engine and rev limit lights will be illuminated on the dash.

        That was my concern, thank you.

        Hmm, well then my earlier point still stands...this would be sweet for any car not concerned with emissions testing.

        I understand the check engine light but why the EML and rev limit lights? Also if the EML light (throttle is supposed to become restricted) is on how are you guys bypassing that?
