[Gmecm] Re: Datalogging '94-'95 LT1 computer

[Sjödin Robert]

Will Tuner Pro RT work on Corvettes which have a CCM (90-96?)? As far as I can tell the CCM sends a $F0 poll that the ECM will respond to but when the CCM sends its poll it (I think) does not wait for an idle line. 

I've had some problem when trying to run some F-body programs on my 91 Vette, I thought one should set the CCM in mode 8 to get it to work? Sorry if this question is little off topic.  

Rob

Since Dave was kind enough to bring it up, I should mention for completeness 
that TunerPro RT will work fine for ALDL monitoring/logging the 92/93 LT1s 
(DAx), but you may run into trouble with 94/95. This is because of the 
EE/EEB masks' message schedules spewing out unsolicited data (similar to 
$58). You must first send out the mode 8 silence command at the proper time 
to get the ECM to shut up before the software can connect.

I will be re-writing the ALDL engine within TunerPro over the next 2 or 3 
months to solve this and a few other issues, as well as add a bunch of other 
features (histograms, new logging functionality, etc).

Also, TunerPro RT is also free and registration is 100% optional. If you 
like it but feel you'd rather not spend the $30, then don't. Contrary to 
popular belief (or, to quote one at least), you don't always have to pay if 
you want to play! ;-)

While I have your ear (er, eyes), the next version of TunerPro will feature 
ALDL data tracing such that you can monitor where in a table (spark, fuel, 
etc) the car is actively running. The cells in the spark table, for 
instance, will be highlighted based off of the RPM and Load information 
being gathered via the ALDL. Look for that release in another couple of 
weeks (it currently works quite nicely with my $6E '165).

Let me know if (any of) you have anything else you'd like to see TunerPro 
do.
