I know that if you raise the stock redline the ecu it will save the number of times over stock rev. But what about the boost, if we raise it, will the ecu save any error? Same for fuel and timing.

 

No Tiago... But your dealer will be able to tell/see if they look that the ECU has been flashed/modified. It's better to leave the rev limiter stock though.

 

Thanks. I had a 986S with some engine mods (TTP headers, cat bypass pipes, evo intake, re-flashed - more 400rpm over redline) and after two years it took a new engine due to porous engine block. At that time the dealer said that the manufacturer refused to give full warranty because the ecu diagnosis had too much periods over redline. The best deal that they managed it was 50% of warranty, because in their report they said that the car didn't had any aftermaket parts and seemed all stock.

My dealer can help in some issues, but they cannot cheat some tests. I just want to prevent any type of error just in case of a ecu diagnosis. I'm glad to hear that we can play with the ecu, since we don't mess with the stock redline.

 

Not an attorney, but I thought that under the Magnuson-Moss Warranty Act there has to be a cause-effect for anybody to deny coverage. Also not a mechanic but how does over reving an engine cause a porous block? Is there a mod that can cause a non-porous block to become a porous block? I wouldn't think so - but!!!! Good luck.

 

Hi Tiago,

There are calibrations with higher rev limiters that do not store a count for ignitions over the stock revlimiter. The GIAC calibrations for the 997 Turbo do not store these unless the car revs past our rev limiter. I posted the following on other thread.

 

The problem it wasn't the cause of the porous block, because it was well know at that time (2002) that it was a comum problem in carrera and boxster engines. The problem it was that if you don't have the car stock you will lose the warranty. After the manufacturer analisys of the ecu diagnosis they realized that the ecu it wasn't stock due to the higher number of periods over rev for a stock ecu.

 

Thanks for your input. Can you tell what can i expect with your newest version for a 07 tip (stock intercoolers)?

 

Hi Tiago,

Here is the dyno plot for our latest tiptronic file revision:



We used Clay997tt's car for the revision as he also added a GMG exhaust and GT2 style intake before the flash. You can see his review here: https://www.6speedonline.com/forums/...-system-2.html

His review is post #47.

 

My understanding of the act is that since the "non-stock" ECU did not cause the block to be porous, Porsche can't use the "non-stock" ECU as a reason to deny the warranty claim.

 

I would say check Protomotive or Switzer...They made the quickest tip cars also

I know some of then ran 0-60 less than 3sec and 60-130 6.8sec!!!

 

That is true with 6.8 sec. A guy in Houston, Anthony, pulled a 6.8 at Lonestar track. It looked so smooth going down the track that it looked slow, but when you came back the time was 6.8. Very impressive.

 

Once i'm from europe and we use 98ron (your 93), i supose that the numbers will be higher for me. Can you send me a pm with the price and the things needed for the re-flash?
The mods had nothing to do with the porous issue, but in europe the manufacturers rule over the customers. You don't have only bad things in US.
Quick cars with ~10k on mods. And you don't need many things to achieve that price with 997TT aftermarket parts.

 

oops - Didn't realize you were not in USA.
