Got one run in last night and then developed a valve train noise so I put it on the trailer. Lost the time slip but it was like 7.50/104mph. Peak pressure was 11psi @ 20 degrees timing. Looking at the log this morning I learned a few things.
1.) I wired a fuel pressure sensor to the Megasquirt and logged that. Learned that FP is spiking under really low pressure and aligns with the really rich AFRs. As psi increases, fuel pressure falls back into place along with AFRs.
2.) I hit the rev limiter at the end of the track and the ecu was pulling timing for almost two seconds at the end of the run. I had set the limit at 6000rpm with a 200 rpm hysteresis and my rpm was within those margins for quiet a while. So, gotta bump that up a little. 6200 next time.
3.) I really pussy-footed the pedal. I came out of the hole really soft and even still broke the tires loose. My '60 was like 2.00s but throughout the rest of the run my TPS never went over 80% and was mostly around 75%. It's like something fell behind the pedal and blocked full travel cause I always try to push the pedal through the firewall and usually get 97-100% tps. Definitely left some power on the table.
Gonna pull valve covers today and see what's going on under them. Sound is def valve train but I checked torque converter bolts while at the track just in case, 'cause that one has bit me before and can sound deceptively like a valve train noise.
