And do you know if is there the possibility to buy a software that allows me not only to read the ECU but also to modify its main values ? What i mean is if is available on the market a program/sotware to modify the ECU values depending on my daily needs ? Thnks in advance.

Thank u Loren !!!

Hi guys, i'm searching for a sotware with the relative ODB cable to read the Porsche ECU. I know that there is a tuner selling this article but i can't remember its name, can somebody help me with the link to their website ? Thank u

Yes, they should be, but for the best way look at the "K24 wastegate boost kit" in the "installation support" of the EVOMS Website. Bye

Don't worry about your new 75 mm TB, air is never too much !!! You will easily get 1,2 bar overboost playing with the gates and, sure, you will feel the difference ! 0,2 bar boost more at 6000 RPM are about 50-60 HP more and lot of torque at medium rpm! I had your same problem with the kit in the first installation, so i think you will need to make some works on the connecting rods to make them fully adjustable. I'm not sure, but i think that the EVOms kit has the connecting rods of the wastegates just a little bit too long ! Finally, the way you want to set them up, starting from zero and moving little by little, is for me the best way to go. Enjoy !!!! Bye

I don't think you have leaks! Ok, your ECU should be perfect, but the way your engine runs is not good ! My car actually runs with 1,3 bar overboost, 1,1-1,2 in the 3500-6000 RPM and 1,2-1,3 in the higher RPM, with the OEM internal parts. Sure it's not smooth as before but still must remain the possibility to control the boost from 0 to 1,2 bar with the throttle. It's not normal that it goes from 0,4 to 1,0 without having the possibility to keep it in a medium position ( 0,5-0,6-0,7...). Imho you should check with great attention if the rod of the new wastegate is able to move freely without touching any other parts. This could produce a similar problem to the one you have. The problem should be in the way the wastegates work but in my opininion should be easily solved if you check with great attention the work you have done ! At the end remember that with the basic setting ( 3 turns of preload on the spring wich is a better way to regulate them instead of the mm measurement from the end of the rod) you will not get more then 1,0 -1,1 bar, to get the best you will have to preload at least 6-7 turns but goes step by step, it's better and safer ! Let me know!

When i have made the first test at 14 mm rod setting when i say that the boost increases to 1,0-1,1 i mean this is the value i see on the gauge of my car. In other words, a 0,83 bar preload setting of the spring inside the wastegates gives a result of 1,0-1,1 on the gauge. And a 17 mm setting means a 0,93 preload setting of the wastegates and a result of 1,1-1,2 on the gauge. But to know if there's something going wrong in your car, and i don't think that you have something wrong, i need to know if your ECU is original or not. If you are starting from an original ECU i think that what you get is correct. My starting point was a reprogrammed ECU that with K16 turbos was able to give me a 0,9-1,0 bar on the gauge with a 10 mm rod setting of the wastegates giving a spring preload of 0,7 bar and when i have upgraded my car with the K24, using the same map gave me the same results. So you can see that our starting point are different: Your car starts from a rod setting of 10 mm and a gauge pressure of 0,7. My car started from the same rod setting and a gauge pressure of 0,9-1,0 gotten with a flashed ECU. My opinion is that with the programmation of the ECU we can get, no distinction between k16 and k24, max 1,0-1,1 bar pressure on the gauge but if we want to go over there's no other way that play with the OEM wastegates with all the problems that we know or change them with the wastegates boost kit which creates a new starting point for new and higher regulation. But don't forget that with K24 turbos you will never get more then 1,2-1,25 bar at 6000 RPM, this the maximum air flow that they can supply, not 1 liter of air more, but in the overboost range, i mean around 3000 RPM, you could theorically get 2,4-2,5 bar which is enough to destroy your OEM connecting rod in 2 seconds. If i can tell you my experience, when you will have 1,3 bar at 3000-3500 RPM, 1,1-1,2 from 3500 to 5000 rpm, and again 1,2 at 6000 rpm with some peaks of 1,3 in the last rpm, with original internal engine parts, your car is near to be perfect. But before you need to flash your ECU ! Bye

You have been of great help, I have on my car the K24 turbos but as you mention with the 0.9 boost setting I believe because it is the most I see pressing hard with peaks of 1,1 maybe sometimes when I take my foot off the gas. I believe that actually your real boost pressure is 0,9-1,0 bar, because tthe 1,1 you see when you take your foot off the gas is not real but only the pressure that the boost sensor sees when you close quickly the throttle before the diverter valves open. Sometimes i see 1,5-1,6 when i take off very quickly my foot off the gas. I am getting the EVO wastegates tomorrow and I plan to install them with the 1,2 setting as you mention, I also bought the EVO FPR Fuel Pressure regulator to be on the safe side with gas as the boost rises (don’t know if you did that also). Actually i have the EVO kit installed on my car set at 1,1 but not the 5 bar fuel pressure regulator. It looks like the OEM fuel regulator works good at the moment but really don't know at 1,2 setting. I think that should be still enough but sure, imho, you are not wrong installing it. Did you see a significant improvement with the new waste gates? Yes, absolutely, before no possibility to go over 1,1 overboost with 1,0 in middle range and 1,1 with peaks of 1,2 at the max power rpm. If it isn’t too much to ask , please tell me the results from the old gates to the new. Now i see, after 1 week testing, 1,2-1,3 overboost, 1,1 middle range, 1,2 always at max power rpm (6000 rpm) and 1,2-1,3 peaks from 6000 to 7000rpm. (i say 7000 rpm and not 6750 rpm because i have moved the rev limiter higher of 300 rpm). I also bought the EVO diverter valves and the new AIR system from them which I will install also at the same time. I have bought the diverter valves from Forge UK which is closer to me and work great but you will not see improvement in performance as the OEM diverter valves are still working good. But with the new diverter valves you can forget about them for ever as they will work good even with very high boost that make the OEM fail. About air system, no information, as i'm still mounting the OEM one. Bye

Hi contigo, yes, the starting point was an ECU reprogrammed to use my old k16 turbos at their maximum possibility. This means 0,9-1,0 bar which is the best a 996 TT can do with the original turbo equipment. Then i have changed the K16 with the k24 and the result was: Same map...some boost with a little bit more of turbo lag. So it was necessary to upgrade again the setting of the ECU, but as i think you have already read on this forum, i couldn't get out more and i couldn't understand why, until i have read that i had to change the wastegates too. This is the reason why, waiting from my EVO kit, i have begun to play with the OEM wastegates. So, yes, the result of a 14 mm setting is 0,83 bar setting (0,83 bar is the preload of the spring inside the wastegate). While the EVO wastegates comes with a preload of 1,0 bar with the possibility to set them at 1,2 bar and i think something more but it's better not. Now i have finally got the EVO kit and i have set them at 1,1 bar, just finished to test it ! What i see is 1,2 bar overboost and 1,1 in the medium range to increase again to 1,2 at the max power rpm which is around 6000 rpm and some peaks of 1,3 in the range 6000-7000. This happens in all the gear but i see it most in 3rd-4th-5ft while in 6th i see occasionally 1,3 overboost. I suppose i can set them without risk at 1,2 to get some extra NM in the overboost zone but nothing more at 6000 rpm. When the K24 blown 1,2 bar at 6000 rpm this means they are at the top of their performance. If you need some extra informations, just ask, hope i can help you. Regards

I'm waiting to get the wastegate boost kit from Evoms so as i didn't know how to waste my time i have played with my OEM wastegate getting some strange results. I hope that somebody can find something interesting in this test as i really got very different results. I have started from the custom setting which should be 4,2 mm from the end of the rod giving 0,50 bar setting. This is the custom setting of Borg Warner but it's not the custom setting of the 996 TT which should be 10,0 mm from the end of the rod giving 0,70 bar setting. So here begins the fun, as i already knew, with the custom setting no way to get more then 0,9-1,0 bar overboost even chipped. 1 Test: 14 mm from the end and around 0,83 bar setting. The car runs good and the boost increases to 1,0-1,1 all the range. 2 Test: 17 mm from the end and around 0,93 bar setting. The car runs better and the boost increases again to 1,1-1,2 all the range. 3 Test: 20 mm from the end and around 1,03 bar setting. DON'T DO THIS !!!! NEVER !!! :o As i begin to test the car i think... WOW, AMAZING,... the boost increased to 1,2-1,3 all the range but (and here begin the problems) probably the spring of the wastegate is too closed and starts immediately to fail. I make 3-4 test in 4th-5th gear and what i see on my gauge is overboost increasing to an incredible 1,5-1,6 bar, the car really flies but probably fuel pressure is not enough and with 1,6 overboost it really goes too bad. BETTER STOP THE TEST IMMEDIATELY !!! At the end what i can say is that it's been very funny but very dangerous too. IMHO with OEM wastegate you can stay between 14-17 mm setting but nothing more. Hope somebody find something interesting !

Ho Wross, do you know where i can buy the waste-gate kit set at 1,2 ? And if the supplier can ship to Italy ? Maybe you know where to buy the DV too ? Thanks a lot Wross

Thanks a lot Wross, now i know what's my next step!!! Bye

Hi Wross, no, not yet, the waste-gates are stock at the moment!!! I'm thinking about this because some people is telling me that upgradind waste-gates is not necessary for some reason i'm trying to understand but i'm beginning to think that it's a must do!!! Did you have experiences with this ? I mean, have you seen big differences changing from the stock waste-gates to the upgraded ones or you have installed all together with the new turbos ? Thanks a lot Wross

Hi everybody, got news in my upgrade but here i have a new problem, hope that somebody had this problem !!! I have just uploaded new program on the ECU to work with K24 turbos i have just installed. They have told me that i should have got 1,2-1,25 bar pression but my digital indicator shows pressure going from 0,9 to 1,1 that is just a little bit more then before. So we were asking the reason of this situation because they were absolutely sure that i should have get 1,2 even because the same map on a GT2 was working at 1,2 correctly!!! We have decided to check the real pressure connecting an analogic bar indicator directly with the pop-off and it shows what we think is the correct pressure which is going from 1,15 to 1,25 that would be perfect!!! And really the sensation is that the car is quite faster then before even if i was expecting more ! So my question is, does anybody have had problem with the pressure transmitter, may has it gone out of range for some strange reason showing me a pressure that is constantly 10-15% less then the real ? Or maybe i should change, with increasing pressure, the OEM pop-off with two forge pop-off, or something else? Thank you. Ciao Stefano

Thank you so much, lot of ideas ! Where can i buy clutch stage2 GT3RS ? If i ask in Italy to any supplier a clutch stage 2 this is the way they look at me ... :eek: We are 20 years behind you in upgrading cars (except Germany obviously). Thank you again. Stefano P.S. Hey, your car looks great !

Hi everybody from Italy, i have a 996 TT m.y.2001 actually step 1 ECU still with K16 turbos around 490 HP. Now it's time to upgrade but in Italy it's quite difficult and to get around 600 HP i must spend around 20.000 US$ !!!!!! :censored: Nobody supplies k24 turbos except Porsche factory but with prices out of mind, so i'm spending my time looking for new parts in USA. :notworthy: I have read all the topics concerning 996 upgrade in this great forum and now my question is if with the following changes i will get what i'm looking for, 600 HP or around them! K24 turbochargers New cooolers (40% bigger than stock) BMC air filter 5 BAR FPR Wastegate boost kit (set at 1.0 bar) 100 cells catalitic converters (in Italy almost legal) New ECU program (this will be a big problem, don't know yet where to find it !!!) <_< Stronger clutch ???? (any suggestion about the best to use?) Do you think it's enough or need something more ? Any suggestions well accepted !!! :thumbup: Thank you in advance. Stefano
