Re: EFI swap

I used a cloyes adjustable set. No issues besides that I need to run 89 oct and 91 oct when I'm really loaded up going through the mountains. To be honest I think it wanted 89 octane before the cam gears (probably due to carbon build up) and I thought it was a exhaust leak. The 208 should bolt right...

This program runs the cam at seat to seat or .050". So would that be 232 intake/ exhaust duration @ .050? And where would the lobe center line be? 112?

I am 99% positive that installing the cloyes set in the advanced position is "straight up". I say 99% because I did not measure it myself.

That makes sense if the computer stays in open loop. At wot the computer falls back to closed loop, ignoring the o2 sensor and runs off of a fuel table that's programmed in its memory. So if this motor makes more power at say 2,000 rpm... what is telling to computer to add more fuel at wot?
