HV ECU from Auto Enginuity

I'm getting mixed results from AE while trying to baseline system performance. It appears to be modal software without feedback of the current state. It also acts like there are race conditions between the user interface and software operation. Regardless, this is a first listing from our 2003 Prius and some of these values are obviously wrong:

I agree! For example, just getting it to connect to our NHW11 in a way that doesn't induce faults and reliably gathers data is still a mystery. Some of the data values I'm seeing, especially MG1 torque, are really catty wompus.

I'm posting these initial "healthy" tables for Derk who is working on a broke NHW11 and someone I've rented a Graham miniscanner who is interested in their traction battery health. As we figure out how to operate AE to get dependable results combined with gathering more data and analysis, it will be easier to file a trouble ticket that helps them 'fix it.' <grins>

Lessons learned

Loading the data into a spreadsheet helps but it is much easier to understand if the data is cut and transpose pasted into a second sheet. This puts all of the data labels in the first column and subsequent data values on each row. I then take out all but the first time-stamp. The resulting table is much easier to analyze.

Yet that isn't in the owner's manual. Thanks, maybe we'll have saved others from rediscovery of what should be standard operating practice.

"Get some skin in the game" and buy your own. It'll run just under $400, not counting a laptop, and then you can share your experiences with it. At least two others have and use it and TomFreed made some of the first, impressive reports.

Heck, for that matter, buy your own NHW11 and join the party. They aren't very expensive and you'll have a chance to gain practical experience.
