Pro Flo 4 Timing

I have no idea why you would need any other type of ignition with this efi setup.

If there is some sort of spark issue, I’d trouble shoot the system. I have higher compression too, 11.3 and make 505 hp.

The higher altitudes have less air, but the af ratio is maintained by the efi setup.

Its actually the proflo distributor and the MSD coil, just with the hyperspark EFI spark box in the middle. It was not a necessity, just wanted to add more spark in case this was an issue. Never had dirty sparkplugs due to unburned fuel or anything like that.

I installed the EFI system precisely because I was moving to another city and did not want to experience issues with the carburated setup.

I just wished the handheld had a graphing and recording feature to facilitate fine tuning. I have a tuner on another vehicle and that helps a lot to see what is going on, on the proflo you wither have to record the screen or have someone look at it while you drive.
