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

[HANDBLT]

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.

When he term 'PnP' is used in this instance, it is referring mostly to the wiring aspect, but there is still wiring that is involved for the injection. When installing a stand alone EMS, there is a ton of tuning that has to be done on the Dyno, and on the street. It will come with a base file to get it started, but every aspect of it will need to be tuned to the specific engine it is installed on.

Cold start, and warm up, sitting still and while driving
Idle control
part throttle
WOT
transient throttle in all conditions (feathering, tip in, taking off, large on and off inputs while driving on street and track, etc)
engine protection strategies

Gunni, does it have the ability to add active knock control?

The base map will be as good as can be done for everyone and developed over time. So that if people have non stock injectors itīll be a matter of setting them up in the ecu and then itīll fire. Or if someone installs B58 coils , then their dwell time needs adjusting to suit. The primary design purpose of the ECU was to enable the usage of all stock sensors for general operation and then any other sensors, actuators etc via additional wiring that does not damage the original wiring. so if you do put a carbon airbox on and some wild cams, difference injectors, flex fuel sensor, there is nothing that has caused any permanent change to any of the original M3 parts.

It does not have any built in knock inputs, but it can make use of an external knock detection device. both CANBUS as well as analog / digital units and act accordingly. Such as but not exclusive

In essence, this ECU doesnīt have any software limits, if you want it to reduce ignition advance because your rear left shock damper is at 20mm compression from level standstill, it can.
Any control strategy can be adjusted via any other internal channel or any external channel.

Gunni - This sounds really interesting and thank you for bringing a new E30M3 product to market.
By any chance is the software ported for Mac?

The software is not and probably wonīt be ported for Mac supports. Most people will simply run a windows virtual machine on their macs to use a standalone ecu software. Same goes for this one.

Thanks Gunni. I figured it would not be.
I keep eternally hoping that someday someone will port their software for Mac.
I have a separate Windoze laptop for car stuff (my ECU and my ABS).
Every time I open the damn thing If one thing is out of place I have no idea what to do and I'm calling people or Googling (on my Mac).
Its the same issues with my iRacing SIM which is a Windows machine, I know enough to turn it on and drive, if anything goes sideways I'm googling.

Yes itīs just userbase numbers that controls it. Even if the developers would like to just use Linux they canīt as well 90%+ Laptops are Windows based.

Hi. Am very interested

Looking at running full sequential

Have e46 TPS and mount
VAC cam sensor kit
Need a crank sensor. Which one?
Need a Lambda sensor. Or does it come with one?

Standard engine 80 000km

Being installed
Carbon air box
Schrick 284/276 cams
LWF with motor sport trigger TTV
Bosch green injectors 430cc

Iīm not sure where to put this or if itīs even allowed but here we are. Iīve been in the E30 / BMW game since 1997. Maybe youīve 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)

Iīve 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 donīt 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 itīs 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 donīt 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.

Do you still have the stock flywheel sensors and your flywheel has the reference trigger on it? As that is all you need + cam sensor which should be a hall effect sensor to get the ecu to get to 720cycle control.

So you shouldnīt need a crank sensor or new crank trigger of any kind. If your flywheel doesnīt have those and you have bought a 60-2 or 36-1 or similar kit then you can use any crank sensor that suits the trigger wheel, VR or Hall effect the ecu detects either. I see the VAC flywheel can be bought with a 60-2, if you have that then thatīs fine.


It doesnīt come with a lambda sensor and doesnīt have built in lambda controller, so you can choose any lambda controller you want and wire it to the ecu, 0-5v or canbus based.
I hear good things about the AEM X line, without a gauge and with a gauge.

Interested and anxious to see results from the car in the US testing! Curious on the additional harness needed-do you need that to go bigger injectors or is that only if you want additional features/going with coils, etc? In other words, can you use without the additional harness and just use the stock harness? If just using the stock harness, I am assuming you can remove the AFM and run either a carbo airbox or a intake right off the plenum with no restriction?

You do not need it for bigger injectors. The extra injector wiring is for improved fuel delivery which can provide improved performance, improved mileage and throttle response, but itīs never going to be a massive change. The biggest gain is when you can time the injection events but that does require a cam signal.

Yes, you can remove the AFM and modify or do anything you want with the intake system.

Nice, please keep us posted on how the testing/setup goes on the car in the midst of tuning in the US.
