Thank God I am not in your head. Please learn how to spell.

Frankly if you hadn't attempted to insult me I might feel compelled to try to explain further.

 

Is it possible to distinguish between a significant change in performance and a throttle remap ala sport mode? This is a concern I have that would seem to make subjective evaluation of reflash a nightmare. Gerry

 

My Revo experience mirrors some of the other comments re. other flashes, but with the added advantage of switchable adjustability via OBD 2 port:

1) Increased mid-range torque, and improved responsiveness throughout powerband
2) Engine takes on a throatier and more agressive timbre
3) Ability to change throttle sensitivity to a more linear delivery - I changed mine so that it is less agressive and herky-jerky......I never liked the chronosport remap...
4) Ability to tweak engine timing within limits, to take advantage of race gas
5) Custom programmable for different grades of gas
6) Has data logging for different conditions, if you are so inclined.

I also would like to note that Revo HP claims are conservative @10-15 HP, which seems about right.

Overall, significant drivability improvement experienced for Revo supplied 91 and 93 octane maps, as well as my two tweaked 91 and 93 octane maps that have less throttle sensitivity....

 

Can Porsche Dealers see the Flash? Do the Territory Mangers have software that the Dealers don't to see third party software on the ECU? (I have seen a number of people claim that PCNA has technology that there dealers don't to determine Flashes and other possible engine info)

 

George is 100 % correct. While R&D'ing a specific car on a dyno, there will be numerous flashes with different files inputted to see results.

I also had someone tell me that they were told after 3 flashes that the ECU would lock up. Had a BIG chuckle when I heard that one.

The 3 flashes applies to factory programming done at a Dealership.

 

I'd go with a Softronic flash...I'm going to be switching from GIAC to Softronic shortly after having witnessed the difference between the two.

IMO, Softronic has really done it right by paying proper attention to detail to deliver superb functionality, performance, and overall convenience.

 

What is the performance difference?

 

I did my softronic flash last week. It was quick and easy and there is a very big difference in my car.

 

+1 on that question!!! Anything objective to report???
"very big difference" is a little vague... so are some of the other comments...

 

the biggest changes are throttle response. With sport mode on the response is much sharper it's a totally different car. The overall torque has really changed most of all in mid range. The car pulls hard all the way through the gears. I can snap my neck back now from acceleration. Other than that I do notice overall power and hopefully I will have all the info next week. I already have before dyno and my shop is relocating and their dyno is not installed yet. As soon as I get it done I'll post everything. Meanwhile if anyone wants to check out my car pm me I'm in bergen county N.J.

 

Not to get too geeky but the limit to flashing is primarily based on the EEPROM (Electrically Eraseable Programmable Read Only Memory) /Flash memory used. The memory contains cells that have a finite lifetime that very depending on what the ECU/DME uses.

 

Maybe I am misunderstanding what I read on another thread. I thought that you had said that the ECU can only be flashed 3 times. So are you saying that the dealer or factory or individual can only flash the software back to stock 3 times?

thanks in advance for a explaination, Mike

 

Sounds just like the changes that occurred when I had APR do my car. Unfortunately I did not do any before after real dynos just the old reliable butt version.

Again I have hard time understanding how one software could be significantly better than another.

Except maybe in the case of the GIAC which to the best of my understanding when I was first looking at software only programmed for 91 Gas.

My APR has Stock, 91,93, and 100 available at any time I want to change.

I run 93 all the time. When I do a DE I will try the 100.

 

Yes they can. If I can see it using a PIWIS for 2 minutes you can bet Porsche can. It's hard because everyday I have to tell people thinking about flashing their cars that there really is no way around it despite some of the marketing claims I see. If the dealer goes looking and wants to deny a claim they really can based on your ECU showing up as having been modified. As long as you know that up front and/or have a cool SA at the dealer you're ok though.
