Simple solution if that is a problem is a paperclip bent very carefully to ground FP and GND on the Diag port together. That will make your fuel pump run constant, its my simple solution for fuel pump control on megasquirt and has been for the last 6 months.

zoom2zoom posted while I was typing lol. connect FP+GND to make the pump stay on.

put some paint thinner in there.... aka octane booster...

yeah you're right I was thinking of closed wastegate, open piping. :crx:

We buy unleaded 115, its $55 for 5 gallons. Yes, leaded will destroy wide bands very quickly. I guess the old $600 Bosch O2s were actually very resistant, but they don't really exist anymore, for good reason.

So, what kind of AFRs could I run?

run 12:0-12.5:1 regardless of higher octane.

the extra detonation protection might be nice, but with fuel, stick to it being about fueling.

Thanks. My clutch won't take just 10psi anyways.

I did just replace my dif fluid and there was only a tiny amount of 'metal dust' (?) on the drain magnet. Seems good for 4K turbo miles, But I am still working on that 97 m-edition parts car.
