found a great tuner for the west coast guys

I use EASE for datalogging and Moates Ostrich for emulation. I've probably burned over 1500 different calibrations between the Xfire and the LT5 motor and not all had to do with just VE and Spark.

It does take a lot of time to simulate real world driving, but it can be done on a braked dyno. It allows each TPS%/load to be held longer than on the street and for each cell to be dialed for max torque. A few of the better OBD2 tuners do part throttle tuning on the chassis dyno, which is why their cost is higher. But i guess it all depends what equipement you use. As you know, emulation speeds up the process considerably.

Emulation as you know, reduces tuning time considerably. Moates' Roadrunner works well for OBD2 emulation.

I am happy to hear that you dont just tune VE and spark. There is so much more to tuning that that.

Do you like Ease? I have been eyeing Ease for a while.
Did you get your copy from John at TeamZR-1? He seems to be quite knowledgeable.

Thanks for teh response.

Hog,

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.

Hog,

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