  • E30 M3 PNP ECU actually now available - ALL stock sensors used , flywheel included

    Im not sure where to put this or if its even allowed but here we are. Ive been in the E30 / BMW game since 1997. Maybe youve seen my name (Gunni, GSTuning) around in the turbo E30 scene over the last 22 years. (E30tech, R3vlimited, E30Sport, E30Tech, E30Zone, bimmerforums, boosted groups on fb, etc etc)

    Ive just completed producing a E30 M3 specific single box solution PNP ECU that can run all stock sensors, takes in all stock inputs and operates all stock outputs
    I just tested the trigger speed to 12000rpm.

    I dont want this to sound to advertisy but I feel this is an ideal solution for most M3s over essentially any other solution in the aftermarket so far as it retains the stock loom without any modifications. It can if you want run the engine on the AFM, TPS switches, narrow band lambda sensor etc etc. It is in every way better than the stock ECU with its USB communications and error detection functions and safety features and definitely better than any piggyback option. A M50 based TPS can be plugged right into the stock loom and will work.

    Some additional features are available with a overlay loom (additional loom not meant to damage the stock loom) thanks to the extra 40pin connector. All the 35 OEM pins are accessible in the 40pin connector for fault testing or if you for instance want to use the narrowband lambda signal for wideband lambda 0-5v you can wire it in there without having to disturb the original Lambda connector in the oem harness.

    4 Internal ignition drivers , for the M5x COP, B58, S55 etc type coils
    4 Logic level ignition signals, for the R8, VAG, R35, LSx etc etc smart coils.
    4 Injector drivers for if wished sequential individual fuelling
    2 spare outputs when all injectors or ignition outputs have been used up.

    New inputs possible over OEM
    Flex fuel strategy
    Any kind of 0-5v sensor (pressures, temperatures, positions)
    Any canbus based value from any other canbus device.(wheel speeds, EGTs, analog expansions,
    Cam sensor for engine cycle phase determination for sequential injection and individual COP operation.
    400kpa map sensor onboard

    The ECU also has 8GB onboard logging with flexible logging setup such as burst mode and variable logging rates and a very flexible and complete log review program.
    Closed loop lambda with short term fuel trim as well as long term fuel trim.
    The ECU also has torque modelling just recently added.

    The ECU also has one canbus, but the ECU has been outfitted with a 16pin connector that provides 12v and gnd as well as CAN high and CAN low for 4 devices and so you dont have to do any splicing. This can be wideband controllers, loggers,, ABS units, OBDII readers etc etc, anything that is available via CANBUS. The 40pin also has a further pair of CAN high and low pins.
    The ECU has OBDII PID functionality, so any OBDII reader can retrieve any OBDII variable from it (Torque app, RaceDash, Track loggers)

    It can run any form of load input measurements for fuel and ignition independantly of eachother, Alpha-N, Speed density, Alpha-N * Speed density(most ideal for the S14 engine), AFM, MAF, Throttle mass flow. You name it it can do it.
    Fuel table can be VE based as usual or fuel mass based.

    Recap : completely new ECU, not a piggyback, no software limitations.

    Let me know if you have any questions.

    Sounds perfect. Do you have an results of this implemented on an e30 m3 with the overlay loom?

    Price? Pictures?

      Hi.

      See here - PNPECU E30 M3 PnP

      No pictures, but in general youd disconnect the stock injector connectors and tuck them away and fit a injector loom coming from the ECU. The ECU extra pins have 12V there also so it owuld be a simple loom to add.

        Seems great. would love to see it installed on someone's cars and results.

        If you need a test car in Florida...

          There is a car being tuned with it soon in the states running all stock loom, Ill post results and tuner feedback when its done.

                This sounds amazing! I'll have to read more carefully through the document, but can you actually order it now? Is there a price?

                    sounds like the LENZ, but with closed loop WBO2, flywheel RPM accuracy, and sequential injection. Oh boy, did I just date myself on how many 'things' I've tried on the S14??!! lol

                    I like it. Is there somewhere the software can be downloaded and looked at? I didn't see it on the website.

                        Is this just plug and play?
                        Are there any advantages to using this with a stock car?
                        Would it improve anything in terms of drivability/reliability?
                        Thanks.

                          For a stock car this greatly improves investigating any issues.
                          Reliability can be improved given that it can run multiple engine strategies at the same time, like if the map sensor fails or the vacuum line to it fails, the ECU can go to pure Alpha-N. This coupled with a wideband sensor can keep the engine running despite losing some input sensors.

                          Drivability can be improved via the acceleration enrichment / enleanment vs the original DME just relying on the AFM flapper position.

                            So, correct me if I'm being thick.
                            You can install this ecu, and fit a carbon airbox, and it will adjust everything automatically and the car will run fine?
                            Or just run it with stock setup (afm) and again it will adjust itself accordingly and work off the shelf?
                            Just trying to guage things before I commit.

                              I dont get where you think this is self tuning.
                              This is a standalone ecu and has all the pros and cons that comes with that. This additionally does have short term fuel trim as well as long term fuel trim so it can survive quite well without any intervention by the user. But proper tuning should be considered the normal procedure for using this as well as any other tuning solution. My free support provides you with the help to get fuelling correct in all situations.
