Finally got AutoEnginuity and have some numbers

First off, not sure if it was just my truck, but I could not get the live data to work on AE. After changing as much settings as I could I finally switched the year of my truck to a '98 and bam...Live data, but now it doesnt read codes from all areas. So just a side note for any other e99 people who might have the issue.


So I have felt like my truck has been down on power so I can all the ICP tests. I have a graph showing the numbers and made a short video. In the video the table goes as follows...

A B C
D E F
G H I

a. Engine rpm
b. Injector Control Pressure
c. ICP Duty cycle
d. Accelerator Pedal Postition
e. Exhaust backpressure
f. ICP Volts
g. Engine Oil Temp
h. Volume Fuel Desired
I. Fuel Injector Pulse Width

Also have an excel document screenshot with info for those that dont want to watch the video. These numbers were from a stop to WOT in 3rd on a stock tune because I can't easily do 80mph in OD on a stock tune anywhere around my neighborhood. Column 25 and 26 are the last 2 records before I let off the throttle.

In the picture, add one letter to the above (a is b, b is c...etc)



My ICP pressure never averaged above 2500psi, although I did see some quick spikes to the 2520psi area. I also tried it on a PHP 120hp tune and my psi averaged 1800. Is my HPOP getting weak? Or do I have another problem

Yeah I read that, but the guy giving input is not anywhere near stock. Also i'm curious if the early 99's dont put out the PSI like the 99.5-02's because of only having a 15* pump vs 17*.
