No, nothing like that. There are 2 tables for target boost and initial/max wgdc, but they are transmission based, so only one would be active.

That's too bad...

Target boost indirectly ends up being affected because the new X-axis is now Requested Torque.

Now that we can see the tables, it makes perfect sense when looking at some of the stock 07 datalogs.

I think I've possibly found the SI-drive related stuff. There are potentially 4 modes:
mode 1 - requested torque map A (sport?)
mode 2 - requested torque map B (sport sharp?)
mode 3 - requested torque map C (intelligent?)
mode else - either map A(sport?) or map C(intelligent?) based on some condition.

The only other use of this mode byte (that I can make sense of) is for switching between three throttle-based speed limiter tables (all have the same thresholds, though). What also lends me to believe this might be it, is that the usdm 07 STi has this logic but the mode switching is disabled (the mode is a constant). It also has three throttle based speed limiter tables, but only one is actually referenced in the code.

Do you see any logic to prevent use of Sport # mode when engine coolant temperature is below a certain value?

I was only looking at the result (guessing that it impacts the requested torque), so I'll have to dig a little deeper to see if this is the case. Any other info? Does it default to a certain mode on engine start or hard reset?

The car generally remains in the last mode you drove it in. The one exception is if the last mode was sport sharp, when you start the engine (and I'm not sure if this is temp based, but it's likely any time the engine is turned off,) it drops the profile down to Sport mode. There's also a little blue light that indicates the engine is not warm enough to put it into sport sharp mode. When the light goes out, the fun factor goes up!

One of the coolant thresholds is 181F(enable above)/176(disable below). The logic for determining the SI Drive mode (if this is it), is more complex than I would have thought it needed to be. I wish someone with an 07 LGT AT and this ROM (ECU id: 4B12525207) could log some stuff for me. I could send them a custom logger xml and determine for sure if I am barking up the right tree without wasting time on something that might not be it. Even if you have an LGT (07 or 08) with SI-Drive that doesn't match this ROM, you can still log coolant temp and see when that blue light goes out.

Ha, ha. Perhaps the flow charts in some of FHI's recent US patent applications for SI-DRIVE might be of help.

In order to view the flowcharts for each patent, you'll need to hit its "IMAGES" button and have a TIFF viewer browser plug-in. The USPTO recommends the free one available at http://www.alternatiff.com.

Thanks for links Jon. The patents describe what I thought it would look like (see SS). However, there's much more going on than is described in determining the mode from what I am seeing (assuming I am on the right path). I would really like to find someone with an 07 LGT AT with the same ROM to do some logging for me. I can monitor the modes and relevant bit checks and probably make more sense of it (or least guide me in the right direction).

For the SS, their mode descriptions are as follows:
Mode 1: normal
Mode 2: save
Mode 3: power

I'm glad to hear some progress is being made on the Canbus!!

I guess I'll be third in line to buy the new cable!!

I know it's not a LGT with Si-drive, but if you ever need some 07fxt AT logging done, i'd be glad to help!!

thanks again for the effort!!

I have an 08 STi available for dumping.

It won't help unless it's near Redmond, WA.

Colby already has access to an 08 STi. Hopefully he will have something soon.

own an 08 STI and you're correct. behaviour of SI drive is described in the owners manual.

won't go into S# until engine is warmed up. deafults to S ie shut down in S# starts in S. Any engine condition (ie temp) limits reached in S# switches to S
