I got this message putting it on my second laptop. I had to install the cable driver again and my laptop made it COM7 by default so I changed it down to 3 as Datamaster would only let me choose 1-4.

I need to report that there was an error in the Scan9495-V6 zip file which is intended for use with the L32 engine V6 cars. The file contained the MALF.csv file for the V8 cars instead of the MALF-V6.csv file for the V6 cars. That has been corrected now. Renaming the file, while it would allow the L32 app to run, would render the DTC feature inoperable. It would show either no DTC's or the wrong DTC's.

Again, this is for the V6 cars, not the V8 cars.

Update:
To all users:
I have placed a beta version of this app in the Trials folder. It has added automatic transmission datalogging capability.
It produces a file similar to the type for the engine scan but with the word "trans" added. There is no capability yet to load the file into the app for viewing. So you might want to use Microsoft Excel or Apache Calc to view it effectively.
There is an added transmission data tab to the right end that has a new format for the transmission data but the old tab works as usual. Eventually the old one will be removed. The new tab uses a checkbox to select the datalogging.
If the checkbox is checked and scanning is started, a datalogging file will be created separately from the engine file. It is not necessary to run both logs or both engine and transmission scans at the same time.

I would like to ask a favor of anyone with a normally-acting transmission. It would be a great help to have a known-good log file to use in comparing results. If some users could run a short scan while driving the car a few minutes it would be a great help. Just drive normally from a stop up to about 45mph through all the gears and slow back down to a stop. It would also be helpful to make sure the TC lockup occurs even if that takes longer to scan. You can elmail the file to me at scan9495@gmail.com. ManyThanks!

By the way, this app had had over 600 free installations. Folks email me almost daily with thanks. Might want to pin this topic?

Thanks to the fine effort by "rngilliland" (Rob), we now have a known-good auto transmission scan. It is posted in the same folder as the beta version of the app. In the future, it will be inside the main zip file. Thanks Rob!

This app now supports the 93 LT1, all scan features except the early 93 SIR module. Late 93 SIR is the same as a 94. The 93 SIR may be added soon.

I've been using this program for a few months now. Haven't had a single issue with it. Works great for abs diagnostic. can also command open loop which is good for testing. That's just what I've used it for.

Tubby says com port not available? The only time I get this error is if I'm already running another program like tuner pro or winflash or if my USB is not connected to the computer.

Thanks for this great program Gary, I'll help in any way I'm able.
