Reply to "EFI conversion of my Spyder"

I worked on the injection more today. I took a 10 mile drive after it was warmed up. I turned on Autotune and initially set it to easy(cell change resistance). Once I get it closer I'll change the setting to normal.

It seems to have MORE power than with carbs, especially down low around 2000 rpm and up. And it's smoother. I'm using MAP(manifold air pressure, or vacuum since I have no boost) for load sensing right now. At idle I have 48 kpa(kilopascals) which is about 14 and change inches of Mercury. Not what a stock motor has, since my cam is lumpy and lots of overlap, but more than enough to use for load sensing.

The cylinder head has stayed the same temp as the other day, right around 180. After I came home and shut the motor off, the intake air temp went up to over 200 F, which is an example of heat soak. It cooled right off when I restarted it. Cooling fan came on a couple times, the engine seems to warm up quicker when the AFR isn't bloody rich!

It was 55 today and sunny, no wind. It was a beautiful day to be out and about with EFI!
