Not for Nuthin' But Close!

[Billy Nees]

I'm home from "The Grove" and have learned and remembered a lot! All from one not very good run!
Info, info, info, there can't be enough when dealing with an F.I. combo.
(Yac, you need to read this)
With the new header and cams installed, I've managed to slow the car down about 4 1/2 tenths. The HP tuners deal is a fine tool for manipulating the OEM ECU to get it to do what it needs to BUT it doesn't offer me a TRUE O2 reading.
On Thursday morning, I installed an old LM1 stand-alone O2 and Friday made one Q run. The A/F ratio was between 16-1 (starting line) and 14.5-1 (finish line)! And that was after adding 5% more fuel than the last time the car was out! After that run, Doug added 10% more fuel and......... it rained for the next 2 days.
Monday morning, I started the car up for the first time since adding more fuel and it was a different car! Here's where the remembering part comes in, remember me saying that I was having a hard time staging the car because I couldn't hold it against the converter? When this whole thing started, we could easily hold the car at 2000-2200 RPM on the line. After the header and the cams, I could barely hold it at 1500-1600. Not any more! I can hold it at 2500 if I want to now. The converter is acting that much looser. What was the old tuners trick about using the converter as an in-car dyno? I can't wait to get this thing back out again!
