Got my CTT ECU flashed by Upsolute!!

Streetcrawler · 01-20-2011, 11:55 AM

But feel like a kid that got a bicycle on a snowy x-mas morning. It snowed here last night so I can't "try it out" yet.

I will get some driving impressions so and take it back to the dyno to compare to my stock run and report back.

what year and how much? Looking forward to hear the results

Was it just a flash and can you put it back to factory?

Streetcrawler · 01-23-2011, 09:09 AM

Yes. Just a flash and could be returned to stock if you really wanted to. Although I'm not sure why I would ever do it.

wcc · 01-27-2011, 04:59 PM

Anymore details on this? I would be interested in cost and the hp you were able to achieve...

Streetcrawler · 01-28-2011, 12:38 PM

Flash is about $700.

On my 04 Turbo is is supposed to give about 80 more HP and TQ. Taking it from 450 to 530 crank.

I did a stock dyno so I would have something to compare it to. I will get over to the dyno in the next few weeks and do another set of runs and see what the real difference is at the ground.

Anything to report yet?

stealthn · 02-04-2011, 04:58 AM

Yes waiting on the results. I was at a Porsche event at the dealer the other night and talking to the head tech I asked him biggest bang for the buck for the upgrades of a pepper turbo (other than the uber expensive porsche kit). He said flash it, said all the flashes were pretty much the same and they've seemed to be very reliable afterward.

I've driven about 500 miles so far. Including a trip from Denver to Copper mountain to ski. (up to almost 12,000 feet elevation fully loaded with people and gear )

Honestly the first few days it was a little hard to tell a difference.(but it was snowy here) The more I've driven it the more I can tell a difference. Runs very smooth, no hesitation at all. Seems to pull the hardest in the lower gears(duh). The verdict is out on throttle response. "Seems" better but not sure it's not my imagination right now.

stealthn · 02-04-2011, 05:39 AM

Good to hear, I would assume if it truely was 80 Trq, there would not be a "seems", it should be a hands down, no doubt about it. I can't wait to see the dyno numbers.

Thanks for sharing, and any difference in MPG?

Wheel Dynamics · 02-04-2011, 08:34 AM

Be nice if you could run the Dino and really see if it is there...

Sorry for the delay guys. Sometimes I kinda forget about my CTT. It was time to dust it off and figure out the issues since the dealer had been no help.

I ordered some APR R1 Diverter valves for the car. They did not list them on their site and had to do some "research" to make sure they would work properly with this set up.

Finally got them Friday and rushed to put them in Saturday. I wanted these over the "piston style" diverter valves simply to reduce maintenance in the future. These are an upgraded diaphram style similar to the factory units. On the CTT they are located in a very inconvient place to change so you don't want to go in every 10K miles to relube them like some piston style vlaves require.

CTT now accelerates MUCH smoother and MUCH harder than it did before. I think this is the issue that was holding me back from getting a good solid dyno run on the Upsolute chip. Think the chip just exposed the weakness of my old stock BPVs. Just to be on the safe side I also have new coils on the way. They should be here tomorrow. I will get them on and hit the dyno ASAP.

I can say already that with good working BPVs the CTT with the Upsolute chip is very fun to drive now.

Here are some pics of the APR R1 BPVs

APR R1 BPV sitting next to the factory valve. Obvioulsy with 2 turbos you need to buy two of these. Ask for the "blue" springs to be installed.

stealthn · 08-23-2011, 06:25 AM

Can I get more detail on the install, and why you chose APR?

Thanks

Streetcrawler · 08-24-2011, 05:10 AM

I had Forge BPVs on my Audi S4. They were nice but you had two service them every few months. The pistons would start to stick, you would bleed boost and get error codes.

I wanted an upgraded BPV over stock but also wanted something that is supposed to have stock like reliability. The APR valve is essentially that. It's a diaphragm style valve just like the stock ones, just with more robust parts.

These are pretty tricky to get to so you don't want to have to go service them. Unlike my Audi S4 and 951 where the BPV is right on top of the motor and it only takes 5 min to service.

As for the install. You have to pull the front skid plate off. Then you can see the drivers side valve hiding up behind the boost hose on the inside of the frame rail. The boost hose to the intercooler off and you can reach it. Simply take off the hose clamps, install new BPV and put hose clamps back on. (okay, it's a tight fit and the clamps are a *****, but it really is that simple)

On the passenger side the BPV is in between the fender liner and the intercooler on the outside of the frame rail. You need to pull the fender liner back to get to it. I just turned my wheels all the way to the right, unbolted the fender liner so I could pull it down out of place and then I could get to the BPV. I also pulled the shroud off the back of the intercooler.

Hoe that helps.

Thanks, the Champion ones are diaphragm as well but have the 90 degree vacuum inlet so the lines don't crimp.

Did you get a dyno yet?

Streetcrawler · 08-26-2011, 06:48 AM

Did not know about the champion ones. Thanks. Will keep them in mind for the future.

Coils got here Wednesday. Hve not put thein yet. Maybe tomorrow. Then I can schedule dyno time. (of course I think I hear my driveshaft starting to thump now too....grrrrr)

Streetcrawler · 08-28-2011, 06:17 PM

Good news.....got my coils in today. Old ones looks good, no cracks so it must have just been the BPV issue. Who needs some good coils?

..and the bad news......Something else to fix now first!

The most common way to 'upgrade' the ECU is using either plug in modules as mentioned above or using a specialist tuner who will use an OBD Flash tool. These devices generally plug into the diagnostic port although in some cases the reprogramming is done directly on the circuit board. Maps are supplied by tuners.
An alternative to modifying the on-board chip is adding an external device, often known as a tuning box. The abilities of the external devices generally reflect on-board chip modifications, with the advantage that they can be easily removed to restore the vehicle to standard. Adding an external tuning box is generally only possible on modern engines with external management ports.
