Reply to "EFI conversion of my Spyder"

Yeah, ship the car to St. Lucia. You'll give me the money for shipping both ways, right, Gordon?

As I mentioned on Joe Fortino's post, it was 57 today. Garage and side door open wide!

I installed some nutserts in the front trunk so I could bolt the tank in MUCH easier. It used to be a "fun" time with the wife getting those four bolts in. Got the tank install checked off the list, and re-installed the aluminum under-pan in the front.

Then moved on to more tuning. I got the start/warmup a little better and have the warm idle nailed, AFR sits at 14.1 to 14.3, cylinder head sensor is at 180F. Where the sensor is located gives about 50F LESS than the center by the plug, so idling my heads are at 230F and STAY there, no temperature creep at all.

I started playing with injector voltage correction, the fuel sprayed varies quite a bit with battery voltage. Each injector has a curve, but I didn't get a spec. sheet from CB. So you have to wing it. Mostly my voltage stays at 13.5 to 13.8, but this curve is for when your regulator dies, or your gas heater AND lights are on, which drops the voltage down to 12 or 12.5.

I started playing with the VE(volumetric efficiency or fuel load) table, changing cells and revving the motor slowly(no acceleration enrichment is programmed yet). Anyway, getting there, slowly.
