Are you worried about the standard electronic distributor spark energy at high rpm? I guess that could be an issue on a heavily modified engine. I think there is a derivative of the Weber Al_pha system (did that to stop the expletive filter
) that has a 2D mappable electronic distributor box for use with DCOE carbs - I'm sure such a system could be adapted to suit the boxer. I believe it uses a crank sensor, throttle position sensor and coil packs. The mapping bit basically matches the ignition advance curve to your carburettor response, so could easily cater for downdrafts but you would need to optimise on a rolling road.
I've never been a big fan of EFI but for some reason I really like the idea of direct ignition
Perhaps its to do with those long hours spent gazing at pictures of T33 V8's with dual twin-spark distributors and 4 coils... sad isn't it?
Errrmmmm.........You lost me somewhere between the expletive filter and the 2D electronic distributor box for DCOE carbs
I believe there was smoke comming out of my ears at that point and I could smell something burning
What I need to do , is run the 1.7 16v engine with carbs - so remove the whole ECU harness ( air flow meter, tp switch, idle valve, air intake valve etc etc ).
Problem is that the advance of that engine is standard to be regulated by the standard BOSCH Motronic ECU , as well as the rev limiter and the injectors delay time.
By removing the ECU I need to find a way to adjust the advanced timing from a mechanical distributor with weights in it instead of the electronic one that is now on the engine.
My worries are that it may not be enough for the car at high revs and there is no way of making it have a good mixture without an ecu present and it will be a lot of hustle adjusting the carbs not to run lean or rich .
As for the picture of the T33 V8, if you are talking about the 2.0 liter engine that was placed in the middle and produced 240 bhp in 1967, then its sad for me as well
