BPC vs EGR in the 58 Code
Just as a FWIW, I spent some time on the ecm bench to verify that the BPC vs EGR corrections did work...
On the BBZB BCC at what I'd consider a normal idle, rpm, and temp wise I got the following data.
Using Tunercat, as the editor
and TurboLink, for scanning.
a BPC of .06 got an idle PW of 1.22
.08 was 1.56
.09 was 1.83
.10 was 2.01
.15 was 3.02

Well now that is useful! Thanks for the test bench data Bruce..
Bruce, where do I get TurboLink? website is down..
My bin has .110 for the BPC vs EGR, and it renders a PW of
2.44 @ exactly 750rpm, 175f water, 181f mat, 109 int, 128blm, 941mv 02, and black sooty spark plugs, and black exhaust..
I put it down to .060, which should yield around 1.30 - 1.40 i'd think..
