Hello everyone, I’m new to the Boxer/TR/M board and recently purchased a European-spec 512M. Would anyone happen to know if the ECU on this car is an OBD-II version? Also, is it possible to reprogram it for better performance? Thanks in advance for your assistance!
Agree, all are OBD1 even the listed 1996 model year cars (it has to do with a quirk of how European model years are assigned in certain markets) There used to be a chip available for the car but I don't know if any are currently offered.
Oh! I thought the Euro version was OBD II. If OBD I, is it possible to upgrade it for better performance?
Yea the Koenig Specials chip was what I had originally planned to get for my car but (1) not sure its still available and (2) I have found the car really responds differently to different exhaust options given the varying level of backpressure (my assumption as I can definitely feel a loss of torque with all else being equal when trying/driving with different mufflers and controlling everything else) Note in my opinion the best 'first pass' upgrade for the 512TR is: 1) Remove pre-cats (if your car came with them) 2) Muffler/silencer of your choice 3) +/- hyperflow cat vs OEM cat vs test pipe 4) Euro ECU coding (remove Pin 39 from memory to prevent the startup rich setting) < yes I realize you already have this by default With that, get a feel how you like it and then optimize with a tune/chip. Personally, once I settle on an exhaust I will likely have a custom chip/map made rather than a 'one size fits all' as even that link highlights, it can vary. I have tried Tubi (Race), Capristo Stage 3, OEM.
Thank you for your suggestions. Excellent points. I am leaning towards a Kreissig exhaust because of its harmonic F1 melody. Not sure if this is the best choice performance wise.
If you get it can you please weight it? I am pretty sure that is the heaviest of the aftermarket options.
Why would you want more performance from a 30-year car? And to be honest, its original performance is not bad at all, only the gears are long, but that's normal for the period.
It's a disease. Always wanting a little more power. I dont want to go crazy. Just wanted to know if anything could be gained by an upgraded ECU.
I reached out to Keonig-Specials to confirm my suspicion. They don’t have any 512TR chips left / offer chips any more.
This sounds very interesting. I have test pipes and a Tubi exhaust on my car and I always wondered why my car is starting a little difficult in the morning, even after the spark plugs and the injectors have been replaced.
