Configuration (it's not complete because I'm writing it RIGHT NOW :)
While I'm waiting to get some quotes back on having my rotor machined, I'm going to start building my config files and tables using what information I have right now. I've been reading some of your configurations and I just hope that together we can keep my engine from blowing up hehehe.
Much of this is based off of the comments in JimW's fantastic setup config. I'm going to make a lot of mistakes I'm sure and I'll make comments where I've left items as is because I didn't know if they needed to be changed and where I've put in my own values. I'll be using JimW's values where I don't know what my values should be...let me know if you object Jim. I'll then change these values over time to values that will work with my engine.
- period time 'crank_minper' is the minimum period between trigger events (that is 180 degrees for 4 cyl; 90 degrees for 8 cyl)
- When engine.tps < tps_thres
- fuel is cut if engine.rpm > 'overrun_fuel_cut'
- fuel is enabled if engine.rpm < 'overrun_fuel_resume'
- in between, fuelcut state is not altered (this provides hysteresis, so there is no fast flipping on/off when engine is around a given RPM)
- fuelcut left on if coming from higher RPM
- fuelcut not applied if coming from lower RPM (before TPS was released: since it's unlikely - though possible downhill - that RPM increases with TPS released )
- I think I'm going to use P259_4 for the idle solenoid relay. If INJFET_4 can handle a steady 5 amps (no PWM), I might use it instead.
