Tim,

When you get a moment, can you grab some data for me? I need the following:

Load
Spark
MAF V
RPM

This will be extremely helpful in diagnosing what's going on with the spark. Under heavy acceleration, negative numbers are not unusual at all. However, if you're seeing less that 10-16 degrees under moderate load then something is amiss (no pun intended).

If you could go to the datalogging menu, set up the datalog to read those values, and then run a datalog session it will store up to about 6 minutes of data on the programmer. You can then use Pegasus to pull the data off the unit and send me the file for examination.

I'm curious if you may have a faulty knock sensor or if maybe the knock sensor is picking up some random noise and interpreting it as knock and yanking out timing.

Let me know if you have any questions on this.

Thanks.

If you aren't sure about the datalog feature this should help out...

Ok. I will try to get a data log but now when I connect, I am getting this error message...

Unable to determine Gryphon Model.
The Gryhpon may be in 'Run' mode, is currently set as stock writer,or memory is corrupted.

I reset back to stock before trying the updates. It still wouldnt update what it stated I needed unless I did both updates. So, updated both, then downloaded custom tunes again...

Humor an old man -

It sounds like you successfully updated both the firmware AND the calibrations on your Gryphon through Pegasus, right? And THEN, you successfully downloaded and reinstalled your custom tunes through Pegasus, right?

But now, when you connect the Gryphon to your truck, it gives you an "unable to determine Gryphon model" error message? This is most puzzling, because this error is normally only seen in Pegasus when connecting to the PC, and I can't for the life of me figure out why you'd still be mucking around with the PC, since you've done successful updates.

If you ARE seeing this message on the Gryphon's screen when connecting to the truck, you DID have the ignition key in the ON position before connecting the Gryphon, right?

If nothing I say is helping, it sounds like you will have to get Bill's help on this. I'm out of ideas.

I was prob unclear as to what happened. When it asked to reconnect... once reconnected.. this is when the error appeared. I do not get the option of hitting the 'ok' that is prompted for after a reconnect do to the error. When I go to the update for custom tunes, this option is still available.. I dont think it is finishing the update.

[tadams11201]

Yes, this is when I am trying to reconnect AFTER the download as instructed to from the prompt in Pegasus. I reconnect and get this error. So, after reconnect to Pegasus, I cannot do the ok to finish the custom download.

No, this seems to be a bit of a "bug" (or a misleading instruction), I think. I'm quite sure your tunes ARE downloaded and you can just take the Gryphon back out to your truck and plug it in.

If you see your hex code when you do so, you should be fine.

One more thing, the old "Targeted Functions" menu option that 88Racing was talking about is now called "Custom File Download". (I'll change our list of "fixes", 88).
