BPC-Base Pulse Filter
BPC-Base Pulse Filter
I reviewed one of the threads I started.

Ron,
Here's the VAFPR table I used on my motor. This was based on using the
20-60psi spring on the Aeromotive 13301. FP was set at 20psi for WOT and the values I used were based on calculations after using a MityVac to get the actual Fuel Pressure dependent on Vacuum. One other thing is that I increased the BPC Base Pulse filter Constant to .78. This appeared to have the effect of causing the ECM to react more quickly to changing vac and so change the BPC more quickly. The result was a much better throttle response.
I see in TP Filter is a %. I assume what he meant is 78% not .78%.
So a higher % allows ECM to react more quickly. stock EBL is 38%
Car coming out soon so reviewing where I left off.
