I'm Automotive Engineering student from Finland.

I were developing four-cylinder BMW M10 2.0 '77 turbo engine as my engineering/diploma work, but I have changed my work to Honda D16Z6 SOHC-VTEC All-Motor project. Reasons for this are too high costs for a student, and I definately need a new (and ofcourse better and more powerful) engine to my daily driver Civic.

Pure AlphaN, WBO2 etc now working excellently! Engine runs damn smooth in ~any conditions, EGO correction works etc.

That AlphaN is very easy and straightforward to tune.

I also tried AlphaN blending first, but that doesn't work for NA engine with ITBs, it's only meant for smoothing idle with aggressive cams. config13 bit 2 has to be enabled via keyboard or config.txt to get AlphaN working! MegaTune doesn't have an option for changing it! I had some serious problems trying to get engine working without it first (and blending enabled in MT; It just doesn't work at all).

Questions and answers

Q: I'm trying to drive VTEC-solenoid (it needs positive supply, and has R of 16ohms) from stepper driver IC, because it seems to be able to supply 1A. Somehow I'm not able to get it working; I use MiscOutput1 for it(S259 Q3 = stepper_A, right?). AFAIK when that is activated, output should go to +12V, but that doesn't seem to work. What should I do? I was looking for V3.2 schematics, and found S259 Q7 going for stepper enable, and added that into RPM actuator; It still doesn't work, what might be wrong? -Janne
