Question about ING_DUALOUT

Going to startup the car soon and going to start with wastedspark first. I have compiled a firmware with ign_dualout and is now setting up the config to get this work. I have a preassembled box with 6-2ign option which means ign channel 03 and 05 are set up for logical levels. Therefore i can't use conf a'la Dave as recommended the manual as i would if I had the ign channels in row 00..05. The firing order is 1-5-3-6-2-4:

Is it correct then to set up up ignchmax=05 and h[2]=04 01 07 02 06 07? If not, how should I set it up to work?


Began to calibrate the sensors today. Started with WB02.Used the config from the manual and added my pump_pw_zero:0x64. When i then tried to calibrate the O2% the values were unstable and hade a difference between 20.5-21.5. All values on mlp07 page were unstable except AFR. Any suggestion?

Then i began with EGT. Boiled it at and set the value on 100C. On ice it showed 0 C. Then i put it onto gasflame on a lighter. 880 degress just above the flame. Shouldn't this be 677C? At 15 in the garage it showed 11C. Only changed multipler, the offset didn't change anything.

The IAT and CLT:

Should i be satisfied with this or should i try a diffrent temp sensor file? The reference temp is taken by a normal thermometer

Q: The wiring is almost done, 80% done. Have made a piout table, but unsure about how to wire the knock A&B. Also unsure about the Idle Air Control Valve. It's a Bosch 0 280 140 545 1738 981. It has 3 pins. I guess one is ground, the second 12v supply and the third should be connect to injector #7 or #8?

Q: I measured the trigger angle 60 degrees before TDC.

Q: I want a tachometer signal to the stock rpm gauge. How should i set this up? Is there an output for this, and can vems handle this when I'm using COP?
