First Drive Under My Belt! Lots of questions

Post by psinnis »

Project: 1988 Mustang 5.0 - B&M Roots Blower 5psi - TFI+MSD 6AL

Ok, the first run went well. :lol: Pretting Darn Cool!! This is gonna be lots of fun! Here's what I found so far.... :?

-TPS Signal is eratic. I calibrate it, but still jumps around a lot. Any suggestions?

-Ignition/Timing seems to be good.

-O2 Sensor seems to work ok until drive for 5 mins or so and then it drops off to 0.02v and doesnt move. Goes back to normal if you let the car cool down for 10 mins, then drops out again in 5 mins? Can it be overheating? What should the settings be for a stock 5.0 ford O2 sensor?

-Played with Accel Wizard - runs way better with MAP 100% (prob due to eratic TPS) What kind of ms numbers should I be trying here?

-Played a bit with the VE1 table.... tried a 1.1 scale up and down- noticed quite a change in engine. Does anyone have a table that might be a good starting point for this application?

WOW, lots to learn... but after 1st run, I am starting to understand a lot more!!

Thanks All, Paul
