I knew about the braked dyno and simulating various loads on the car but you also have temp compensation, both coolant and ambient, for instance that would still require road work. The OEMs with all their sophistication still rely on that. The dyno can certainly cut road time down considerably getting to the right tune however. I know that Marc uses an engine dyno for motors being shipped overseas as an example. EASE is good. Not available any longer as a personal copy as I understand it. I got mine 10 years ago. One issue with EASE is that it only records rpm to 6300. So I needed a mod to the ALDL datastream to get actual rpm in the log. For > 6000rpm work, the datastream is still a bit slow so I mostly rely on the WB
log at 35frames/sec. As long as you can get MAP, TPS, AFR, RPM WOT can be tuned.

Excellent, thanks for your input. I agree with you when you say that road work is still needed, no matter how much dyno time is needed.
I wasnt trying to re-educate you, as I know zero about OBD 1 tuning.
Thanks for your insight.

peace

Hog,

I didn't take any umbrage to what you were saying. We're cool!
