the 997 will fit

 

Everything is out and I test drove the car last night, all felt good. However, we do have some code issues.

We currently have a PTM error code. Sport Mode/Over Boost is not functioning either because of the PTM code. Also, If I try and disable PSM it will not allow it to be turned off because of the PTM error code.

We were considering re-flashing the car to making it believe it's a GT2RS. However, in doing so that would zap out my custom GIAC Champion mapping.

The shop may have a solution to trick the electronic pickup sensors from the front diff which are no longer in place. Currently we are doing a little bit of homework to see if this is a viable solution.

Still forging ahead with this mission....

 

Subscribed.

 

It should be possible to turn the code off in the program, it takes some detective work to find the right adress. The GT2rs program won´t work in the turbo, they are completely diffrent.

 

Interesting test day at Sonoma on Sunday.

Primary purpose for testing was for suspension set-up. We started off by adjusting the sway bars to full soft up front and full stiff in the rear, while leaving all my shock settings were we typically have them for Sonoma. We were getting some oversteer as well as some nervousness with the rear when exiting the higher speed turns. After the first session we opted to adjust/soften the Compression dampening. This did help to minimize some of the oversteer, however the rear end was still nervous and unsettled under hard acceleration coming out of the exit of T10. Before heading out for S3 we adjusted the rear sway bar to the middle position. This really helped smooth things out. Next up S4, Sunday's race...did okay in finished the best I could considering the circumstances. After the race and downloading feed back to my Suspension support. The car actually felt really good and now only suffering from mild turn-in under steer at T7 and T11. We feel we can dial that out by softening the compression dampening on the front shocks, which we will try on our next outing.

Now for the BIGGER ISSUES.....the electronics were not happy at all!!! Stability and Traction control were going crazy and constantly trying to control the vehicle to the point were it would cut off power to the engine (meaning, it was chopping the throttle as I was accelerating through and out of the turns)....VERY FRUSTRATING!!!

This was a test session to see how the car would behave with the removal of the differential. This info will now be passed on to the software gurus. Hopefully they can come up with a solution, or already have one.

I am not done yet with this experiment....


SPEEDFREAK:

Do you have any insight why a 2010 GT2RS program will not work?
Thanks,

Addresses in the gt2 and rs file are all mixed up compared to the turbo, I have personally looked at the two files and they have moved every thing around.

 

Any update Vid? Did the electronic issue get resolved? I might want to do this to my 997 c4.

 

Slow for now. Ran into some tranny/throw-out bearing issues when we last tested at Sonoma. Actually had to get a tow back to the pits. Currently we are waiting for the rain to stop here (San Jose, NorCal) to get the undercarriage steam cleaned (its covered in differential fluid, and it stinks!!!!). Once we get it cleaned up we will then drop the tranny and see what's going on with the throw out bearing, shaft, or release arm??? Most likely with the up coming holidays, I won't get to this until mid January.

Plan currently is to sort out the throw out bearing and then reprogram the car to a GT2/GT2RS. My GIAC tune will get zapped in the process, so I will need my ECU to be re-flashed as well. I have custom maps with GIAC, so that is a pretty simple and painless process, other than having to send it out for re-flashing.

I'll keep the thread updated as I take the next steps.

Thanks for checking in.
Cheers,

Did you try calling Todd at trophy performance? I know he has done this for some guys. I know most didnt like it after but he might have some ideas. He is the most qualified Porsche guy in the LV area and that is including the techs at the local incompetent dealer.
I think he is still the only guy in that area qualified to work on the Carrera GT based of the gold status.
Anyways he might have some ideas on how do get around the PTM issue.

 

Make your first loss your best .Sell your car and go find a GT2 .You will save in the long run and have a more valuable car that will hold value.

 

This started out so promising...

Did OP ever get this sorted out? Have been toying with the idea of going rwd but no definitive guide out there I've seen, at least for the electronics

 

WOW! Forgot all about this thread. Let's just say the plan was scrapped after deciding on a vendor who had a solution....

Since then a lot has changed. I dropped my car off with the vendor noted above on 09-11-2015....its still at their shop....
