For the same reasons, no, TunerPro does not do well with these. After the 
re-write, yes, it will work just fine. The problem here is that the ECM is 
sending information via the scheduler to the digital dash. The scanner 
(TunerPro in this case) must listen for the chatter and send the silence 
command first before requesting the mode 1 message X data.

The current build of TunerPro will have trouble with any "chatty" Mask/BCC. 
That is soon to change. I've got a few local SyTy guys knocking on my door 
often to ask me to get these changes in as well, so the changes are 
imminent.

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.

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.
