Does it have an adustable MAP? Wouldn't that help?
It does not have an adjustable MAP, and I was thinking of getting one or making one.
Hmm... There may just be one hanging around close by.
Haha can I assume this is me? Well, I might not have to. I finally abandoned my first attempts at an AFR reader (see below). I tried to be fancy and actually wire something into the wiring harness.
Yes that's duct tape, and no it doesn't read any numbers but 13. I have a digital reader, but it needs a cigarette lighter that functions. Which I don't have. Time to cobble some crap together.
Yep, more duct tape.
So I finally got it all together and calibrated, and imagine my surprise to get actual data. Here's at idle, warmed up.
It's apparently right around the stoichiometric ratio.
This is as lean as I caught it consistently.
I ran it around on a pretty good test, and even running hard on the gas couldn't throw the system for long. It stayed right around here.
I'm genuinely puzzled. I thought for sure a bad air-fuel ratio was the reason for the high underhood temperatures. Guess I'll have to hunt for other culprits.
This is all assuming that I got the AFR setup working properly, but apparently it calibrated right - was reading around 20.1 in normal air. If anyone's curious, here's where I had the wideband bung installed.
At least I can stop worrying about detonation. Probably. Now to figure out cooling off the engine compartment and why my mileage is terrible.
