Re: SkinnyG's '61 Apache

Nice sunny 8°C on Saturday.

Took the truck out for 45 minutes of driving. Low boost (5psi), just tuning.

This is a GM, P59 PCM, converted to boost-referenced fuel pressure and Speed-Density.

While I did, in fact, set the Injector Flow rate to be constant, I did not set the Injector Flow offset (with respect to MAP and Voltage). So.... I leveled the table (same offset column from 0kPa to 80kPa), and datalogged.

Big whoop-de-do. VE needed less than 2% correction.

Could of days and I'll add a few clicks to the boost tee and datalog some more.

REALLY nice to be on the road with it again.

Re: SkinnyG's '61 Apache



Finicky little fittings, and cheap/garbage A/C compressor adapters. Didn't quite get this one to seal I guess.

Took my sweet time tightening this one - snug the nut hand-tight, then wiggle the fitting, then tighten some more, then wiggle. Held a vacuum overnight, so I charged it up and it blows cold.

.... for now.
