Rich AFR's when running 50% Methanol Water Injection......

[Daxcossie]

I decided on running with a 50% methanol mix and my AFR's have gone way too low.

Set-up is on Race Aquamist Pump, single .6 jet on inlet size, activates @ 40 degrees / 14psi.

I will have to go back to using distilled water only as the AFR is too rich as soon as the methanol get injected into the system.

Methanol is a fuel, you need to either re-tune the car leaner on the fuel injectors when the WI is active or go back to straight water.

If you tune for methanol, you need good safeguards to prevent a lean condtion due to any fault in the WI system.
