I'm undergoing a full GT2RS conversion and recently installed a new gauge cluster. Have everything functioning perfectly however when I hit sport, it disables the TC+SC.

Is this something that can be changed/reprogrammed with a PIWIS tool?

I'll be taking it to my shop to know for sure, but thought if any one has done this before, I might pose the question.

 

not sure about your quesiton, what ic's are you planning to use?

 

Regarding the the engine, I'm running COBB, and Champion 68mm VTGs + Champion IC's. But that's not really my question.

My question was referring to the GT2 gauge cluster (as in behind the steering wheel, the speedometer, tachometer, etc.). I replaced it with a GT2RS one - the entire unit. Now when hitting the sport button, it auto deactivates traction control and stability control... true RACE mode :P
I'd like to have the option to switch it back on.

 

So sport normally turns PASM to the more aggressive setting however what your saying your car is now doing is when you hit the sport button it puts the PASM light on which it normally does but also turns off your PSM which is indicated by the PSM light coming on a audible sounds and the corresponding symbol on the dash lighting up?

My first question is this how the real GT2RS works? If so I'm also interested in switch the cluster. Do you have a part number?

From a logical standpoint of you have a car like the GT2rs that is RWD and has all that power when going into sport you would normally want PSM off. Every time you have a wheel loose traction your throttle plate closes with PSM on and it would be counter productive to what the car is all about.

If I were you this is the exact situation is want to achieve. Pending of course the GT2RS operates in a similar manner to a turbo.

 

That's exactly it. I hit sport mode and: "PSM light coming on a audible sounds and the corresponding symbol on the dash lighting up".

The part number is: 99764110584D07

That's exactly what I was thinking about, but I'd still rather have the option to be able to switch it back on (PSM) that is.

There are some cool things that come with this cluster that aren't available on the turbo, like a shift light and stacking of the info data (display boost and fuel range together) as an example.

I had a chat with my mechanic, they're gonna look into manually programming it - but it's the first time they will be doing it too.

 

I called my buddy he's a porsche tech and he said he will also look into it. He turned on my chronograph backlight light so it stays lit at all times for me. If he comes up with something I'll let you know

 

Awesome thanks!

 

Pureporsche, are you still AWD??? With the front diff and axles removed I cannot even switch it into Sport Mode. It fails and will not allow me because of a PTM code that can not be cleared. Also, the PTM failure has limited my boost to a max of 15psi....

 

Unlike the 996 the AWD in the 997 is electrical. I would assume you could bypass this without removing the font wheel drive components. Protomotive say they can install a switch to make the 997 RWD but I have not known anyone to have them do it. This in my opinion would be the way to go instead of removing components stated above.

 

Yes I am AWD. I landed up replacing my front diff and axle and suspension. She's running perfectly.

So latest update on the cluster. It appears that even with the PIWIS tool there is no method of flashing it such that the TC+SC doesn't disable when in sport mode. With that said, I'm curious if these are truly completely switched off in sport on a turbo (as opposed to the GT2)... you know what I mean.
The only true test is to get it on a parking lot in the wet and rip it loose and try to gauge the difference.

The other side affect of the cluster is that cruise control is no longer working (haven't fully tested). Again this is something that I believe didn't come with a GT2, and to be honest I have used maybe once in the last 6 years :P so not concerned about it.

I don't get the PTM failure at all.

In sport mode, with the TC+SC disabled, I can enable PASM (on and off) - no problem.
In regular mode, I can switch PSM on/off, no problem or the PASM on/off with out a problem.

So it's just in sport mode, that I get the "TC+SC OFF" message. But the question remains... is it really off?
If it is, I'm still undecided if it's a cool thing or not. My mechanic thinks it is And if it is - it should be just a beast when I get it on a track
...but it still would be nice to have the option to enable it.

 

How about the pressure reading. Is it still capped at 18psi?

 

Yes it is. I'm way over 18 with my build/tune.
I have been told that it's a hard max limit that's restricted external to the display.

 

So your saying it displays 18 psi but your actually building more boost that's now being correctly displayed?

 

You are correct. The factory gauge cluster will not read over 18 PSI even if you are running 30+ PSI. You will have to install an aftermarket one to truly see what your PSI levels are.

Correct'o!
