I´m not sure where to put this or if it´s even allowed but here we are. I´ve been in the E30 / BMW game since 1997. Maybe you´ve 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)
I´ve 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 don´t 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 it´s 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 don´t 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.
