Yes I heared about Armadale, but that is 45min away from me :(. I'm in baldivis so I guess I'll fill two 200 litre drums every time I have to drive there. My

garage would go off with a nice bang in a fire I reckon.

Only 85% with 20psi at say 6000rpm......really.......do me a favour, crank out the xcal3 and run the following log to redline and prove me wrong. Im not trying to be a smartar$e, I'm genuinely interested in the result.

RPM

FUEL_PW_CLKTIC

MANIFOLD_ABPRES

BARO_PRESSURE

Below is my dyno sheet, United in red, e-flex in green.

Fuel system consists of a Walbro intank, Plaz surge, A1000 pump, standard rail and reg.

Have never logged with the x-cal but will give it a go as I'm now curious.

Based on what you see what do you think the IDC is roughly at toads?

Have been running e-flex for 2 years without issue but only just started using the United.

Based on your dyno chart and a few assumptions:

85% ethanol, 4 bar base, 0.85 lambda, 23psi, 4500rpm - ~92% IDC

85% ethanol, 4 bar base, 0.85 lambda, 6000rpm, 20psi - ~100% IDC

On e flex I reckon ~85% IDC at 4500rpm and ~95% at 6000rpm.

IDC = (RPM x FUEL_PW_CLKTIC) / 1200
