data logging with ls1, obdx pro vt, and tunerpro rt

[bobcratchet555]

Hi All,

i'm fairly new to tuning, but so far have learned a lot from this site and others.

my motor is a '99 ls1/4l60e from a z28 camaro. right now i'm running the '00 firebird bin and used the xdf for that to disable vats, set the tire size/rear diff, and tune the shifting to the point where it's pretty good. that all works well.

the next step is actually dialing in the fueling, which will require data logging. i'm using the obdx pro vt and pcm hammer to read/write the ecm. what is everybody doing for data logging with this device? does it work with tunerpro rt? if so what is necessary? i've found a few tutorials, it seems like of course you need a definition file but what else is required?

thanks!

Hey Bob, I realize this post is a little old. I've got the same car, looking to do the same file changes you did.
Mostly trans shifts, pressures & gear change. Did you have a good xdf file you could share or point me to one.
I've got a generic xdf but dont see where to change shifts point, pressures and gears. Would the correct xdf file
Make a big difference. Thanks f oi r any info you could offer.

What OS do you have?

What OS do you have?

Thanks for responding. I'm not sure what OS, the ecu is still in the car. I picked up a spare from auto wrecker, same car (99 Camaro a4) but the spare is from a v6. Apparently it's different, it is blue & clear connectors. I can post the read file from z28
If you can see what it says. Depending on the xdf i use the fields/tables are blanc or zeros.

I see that the file you posted is OS 9373372. I don't know of any XDF files for that OS. Would you be against upgrading to a newer OS that has an XDF available?

I'd be fine with that. I want to get a second ecu to experiment with, leaving the original one unaltered. I know of an ECU in the wrecker for an s10 truck that I believe has red and blue connectors. Would that be a good candidate for an experimental ecu? Thanks for your assistance!!@
