I’m thinking on a 991.2 tune with them, but communication is difficult to say the least. I like emails to keep things in check when people “forget” what was agreed.

Besides some oddities on the exchanges, I read that the ECU gives a hard time to flash back to stock.

Bear in mind, that the ECU removal is not exactly easy or quick and it mandates a best case scenario of 3 day downtime. If you have other engine issues and you may prefer reflashing before sending the car to the stealership, it may not be readily feasible, hence my question for reviews on how the act on the post sale phase.

Most are nice when it’s time to take your money, but when issues arise, what happens?

 

Have you tried calling Tom from Champion directly?

 

That's why I will wait for Cobb. Even if their tune doesn't make quite as much power, going through this ONCE much less every time you get an updated tune just ... sucks. Then again, Cobb sure isn't showing any signs of having a 991.2 solution yet, as far as i can tell.

 

Seems they might not have for the foreseeable future

 

That’s a good article, thanks!

Although things somewhat stays the same -no OBD tune, this increases my worries about a bench tune.

Even people doing X51 upgrades are having keys recoded. Seems that they have bits of code all over...

 

Recently coming from the 997TT world, I've read countless reviews of GIAC being a very reputable company with a lot put into their products. I know they also do fantastic work on Audi tunes, etc. That being said, finding a GIAC dealer in my area was a bit weird because my preferred shop in Nashville wasn't authorized and the competitive shop already had claim to the local area. That made me decision to go with Cobb, which was an excellent experience. I know that's not first hand experience, but hopefully it helps a bit.

 

Call http://www.championmotorsport.com or PM TOM@champion here on this site he will give you all the information you need even if you don't buy from them.

 

If it’s like that before taking your money, imagine post sale support. Unless Tom is selling and uploading the tune himself, it’s irrelevant as he won’t probably be the one providing support.

It may not be on purpose, perhaps they’re understaffed, but the problem remains the same.

Cobb may take forever, but their reputation and response are notorious.

 

Call GIAC, Ive spoken with them several times. Ive always spoken with Logan who was very helpful. Those guys are really busy over there.

There's likely very little difference between the actual GIAC and COBB tunes as far the performance, its just the access via OBD2 which is proving difficult fro COBB.

If there is a way to switch maps introduced, and one would think that would be the case to stay competitive, the differences between the options would be even less.

Personally, coming from the BMW M car community, it would be nice if the Porsche community would share personal experiences and work together more for the benefit of the whole.

Perhaps, if COBB knew that there were x people waiting for a tune, or GIAC knew that x many people are waiting for switchable maps, almost like a group buy, there would be much more activity in getting us a real tune with some options. All I ever read is individuals requesting information, but no ongoing thread providing updates, etc.

Hopefully there will be an option for 991.2 GTS's soon, because I am in desperate need of a tune!

 

All I am saying it that right now the ECU has to be sent in to GIAC, but if they could locally flash the car it would allow someone to go back to stock before going into the dealer.

GIAC also has handheld flash loaders for other platforms

The hold up is that its requiring too much R&D for the size of the market for the tune. They are not going to hold up development on another platform to devote dollars and research time to the 991.2 platform. In my opinion, now that theres many more of these vehicles on the road, it seems that they can dedicate additional time and expense in development of this tune now that the market is larger.

 

Take it easy dude, no need to be so aggressive. This is just casual conversation, if I am mistaken feel free to point it out.

I never claimed to be an expert, Cobb themselves state in the article that they will be dialing up resources to overcome this last hurdle. My question is why now and not before? I'm guessing, and no more than that, that the market is larger for tunes now, not that there arent other cars running the Siemens setup.

I also understand that at this time handheld flashing is not possible, but that is what everyone is working towards if its possible.

 

Another piggyback. How do you like it? DIY?
It’s so much trouble to get it on that one can just take the ECU out and ship it

 

Hi gals & guys,

Just an update for those still interested in GIAC stage 1 ECU. I recently had it installed on my 2017 C2S (manual) and am very happy with the results. I am just an average 911 daily driver (e.g. no autocross, no legal drag racing, no drifting, etc.) that loves driving fast in the city and enjoying daily, streetable, enthusiast-driving.

Since I cannot provide any numbers and times like the experienced drivers can, I wanted to share with everyone the GIAC stage 1 performance is highly noticeable when driving. The torque DEF comes on in the low end quickly and the feeling of acceleration in the gear shifts is phenonemal. It does pull very hard, too. It drives very much faster than from stock.

As a minor comparison, I have changed out the ECU in my previous 991.1's (stock C2S) and 997's (stock C2S) and will say the "noticeable" performance difference is minor and hard to enjoy. However the GIAC on my current 991.2 is totally awesome with lots of enjoyment in streetable, daily, driving. So much more noticeable power and speed makes the ECU upgrade choice a great move on this generation.

Happy motoring!

 

You cannot compare a tune on a turbo car to a N/A car so any tune on a 991.2 will be noticeable....turn up the boost and off you go.

 

A-men to that! Considering the price, the GIAC stage 1 is definitely going to enjoyably separate one from stock C2S's. Great bang for the buck. Appreciate the tip Bob Z.!
