im starting this thread as sort of a "build thread" but for my MS2. as I understand its a brainbuild and is running a modified basemap of the 1.8 turbo mazda on diyautotune.
Feel free to chime in with your thoughts on my progress and any help you may offer.
What I have:
really weird maps...
So far the car is happy where I need it, on the highway. I can cruise with a 13.7 AFR and get about 23 mpg doing it, excellent! now if only it did that everywhere.
1. it stumbles when you get on the gas. particularly in a low RPM/noboost area.
2. it PUKES fuel into the car on boost and runs about 10:1 AFR
3. VE seems to be doing an ok job of tuning the mid ranges, but as you can see, about 3/4 of the way into boost it starts piling on fuel when its already running a 10:1.
4. my exhaust is crap
Right now I'm starting on page one of the megamanual. and I think I have narrowed my stumbling issue down to too much PWM. adjusting it is where I'm going to start.
Tomorrow I will start posting results and changes, if anyone wants to look at my tune let me know.
