$42 tuning

[shimniok]

All my testing of BPW changes from stock without factoring fuel pressure have resulted in raising BPW and low end goes rich and high end goes lean. So I'm back to calcualting BPW from fuel pressure and not using BPW as a tuning adjustment tool.

I'm seeing the exact same thing in my first foray into tuning; up the BPW, watch low end go fat, top end lean.

My first foray into tuning has me trying to increase BPW but all I get is richer low end and leaner top end... Same behavior?

How does one calculate BPW from fuel pressure? With this spreadsheet? (Fuel InjPress Calc.xls) ?

Here's the one I use for TBI.
