I think I'll get one of them there Dastek unichips instead of the k24s I planned to get. All you guys who upgraded to k24s got boned.

 

The Unichip is VERY old, largely obsolete technology. It was on its way out when I purchased my 996TT in 2002. The Unichip was marketed for Porsches primarily by TRG, although I think TRG dropped Unichips long ago (I'm not positive). Now, the product is marketed directly by Unichip ( http://www.unichip.us/search_results.asp?dhtmlgoodies_year=2002&dhtmlgoo dies_make=Porsche&dhtmlgoodies_model=453054888 ). The Unichip does NOTHING more than a traditional ECU tune (e.g., boost, timing, fuel, etc.). The Unichip has the downside of being a piggyback system, such that it is visible to anyone accessing the ECU.

Finally, contrary to Bass16v’s claim, the Unichip does NOT produce an additional 160 HP at 1.0 bar. In fact, Unichip itself only claims an additional 90 HP and 85 TQ: http://www.unichip.us/DynoSheet.asp?...leID=453054888 . Moreover, given that Unichip also claims an improvement of 2.6 seconds in the 1/4 mile (see above link) (12.2 - 2.6 = 9.6 = LOL), I do not put much credence in their HP claims. On the other hand, an increase of 90 HP (415 to 505) might be possible with an additional .3 bar of boost, more timing, a free flowing exhaust, and a couple of other tweaks.

Bass16v, welcome to 6Speed. Your enthusiasm is commendable. However, you are dealing with a group of guys here who have owned 996TTs for a LONG time and, over the years, we have seen and tried almost everything on the market. Therefore, you would be well served to do your homework before you make extraordinary claims and/or exaggerate performance results.

Regards,

Craig

 

Ditto Craig, It must feel harsh for the newbie, but we are only trying to help him. Bass just start over again, rip that unit out and speak to some reputable tuners on the board, (just look down the right hand side), trust us! They are here to help people, I'm sure there was someone on the board recently that had a bag of problems with the Dastek Unit, I'm not saying you are going to have same problems, but these units are of old and you could have better/reliable performance from something else.

 

It's ironic that on Unichips site in the 911 PORSCHE TURBO tuning section- The car pictured in not even a Turbo Porsche... does anyone at Unichip know the difference between NA and Turbo cars???

He could be running straight ethanol... Higher octane, more boost, etc. They run everything off ehtanol in Brazil, even planes! I know everyone's favorite piggyback tuner in the US was tuning some Evo's on E85 with good results.

Then again there was an article in Panorama several months ago which suggested ethanol is not so good for Porsche seals and such.

 

It doesn't matter I K16 turbo can only flow so much air. There is no way he is making 580 hp with the stock K16. Sorry!

 

Exactly, it is all about how many pounds of air and pounds of fuel are going thru the engine. The art of it all is how to do it without detonation. The only way around this unless you use a blast of Nitrous (Oxidizer), but I think that is cheating…

There ain’t no magic...It is all physics.

 

Bass16 don't get mad at us. We're just trying to keep things in perspective as to how much power certain mods actually make. Like Craig said there are a lot of very experienced people on this site who have tried pretty much every combination insofar as making horsepower. Welcome and please respond.

 

580 ain't happening. Maybe 480

 

Possible AWD dyno left in RWD? There's a number of explinations that could have made you think you were hitting those numbers, however if you laid down a true 580, its not from just a chip.
