Hey guys
At first I am from germany and my english isn't the best. So I apologize in advance if I do not write everything correctly.
My Name is Toni and I've got a 1995 Mazda 323 (Protege) with BP engine (114hp). Its my daily driver and I want to install a VJ23 GTR Turbocharger on it. Here is a pic:
Lots of you boostet the BP Engines in their proteges. What did you do with your ECU? Piggypack? Standalone? GTR ECU?
Standalone is to much effort until de engine runs properly. I'm using a Megasquirt on my other 323, that not the solution for my daily drive 323 protege.
The original GTR ECU would not work without changing the complete engine bay harness incl engine components (air flow meter, throttlebodysensor, ...) and there it would give a lot of problems to combine the BG harness into a BA harness.
The easiest way is to use the Piggypack eManage Ultimate which I used in my other 323 before. I just had to adjust the fuel map and just had to modify the ignition table with decreasing ignition angle while boost is increasing.
When the engine is increasing boost by 0,1bar, then I have to decrease ignition timing by 1 degree. At 0,2bar then I have to decrease ignition timing by 2 degree. And so on. So its called as a rule of thumb.
But there is my problem: I dont know the actual OEM ignition angle, I only know my modification. I only can estimate it from the exhaust gas temperature. Thats not safe enough.
This ONLY works, if the ignition timing stays continuously at the same value. But what when the ignition angle from the OEM ECU is rising up with increasing RPMs? Then this would not work and I would blow my engine after a while of driving because of knocking. Or I am making the ignition timing too soft and I got EGTs like hell.
How did you solved this?
Thanks a lot, Toni
