MicroSquit Conversion, Giving this a try Options

[Mblizzard]

I am pretty happy with my stock FI. But after seeing some of the setups at Okteenerfest, I thought this might be worth trying.

The stock system is not easy to modify and get things running correctly. I spent a lot of time making minor adjustments by trial and error. While I am not looking for huge HP gains or anything, it is pretty clear that the mods I have could potentially benefit from a bit more precise control.

Going to start with fuel only at this point to get things going and see where it leads me. Any help or suggestions for set up would be appreciated.

Since my engine is out, I'm thinking it would be a good idea to mount a 36 tooth trigger wheel in case I want to add a new injection/ignition system later.


Although I can't add to the discussion about how the injection and ignition systems work, I can comment on resistors in the system. If you place resistors in series in a circuit, they don't add linearly. They add like 1/R = (1/R1) + (1/R2).

So if you have a 2.5 and a 3 ohm in series, the total resistance will be 1.36 ohms.

Actually you have that backwards. Resistors in series DO add.
Resistors in parallel use the equation you posted above.

And having a capacitor installed across the coil will cause it to open slower because some of the current that would have gone into the solenoid (inductor) will go into the Cap instead.

And when the drive circuit removes the drive current (PWM or otherwise), the CAP will begin discharging into the inductor providing extra current which would cause the total current to drop less abruptly causing the solenoid to close more slowly.

I did not say across the coil, I said across the RESISTOR.
