GIAC/A.W.E. ecu tuning - first impressions
I just got back from the Detroit Auto Show (superb BTW) to find a magical box from UPS on my doorstep. Inside the box lay a mystery - a promise of excitement, a promise of fun that may or may not be realized.
Now at 2200 miles, the hope of the passage of factory boost restriction being gone has passed. There was no boost unlimitation being unleashed at 2000 miles. Porsche lied. There is no boost and torque plateau starting at 1950 rpm. There is no 18psi boost to be found, ever! Boost never hit until 3k rpms, no matter what gear. Why would they promise us that and deliver nothing even close?
I opened the box to find my ECU. Well packaged, and re-install was a snap. The weather outside was dreadful - 35F and freezing rain. I started up the car half expecting error messages. There were none. The startup idle was smooth, no burps, no hiccups, no surges. I let it run for 10 minutes at idle, blipping the throttle from time to time. No changes. No hint of any difference. Did I just waste $3500?
Next day it is still cold, but dry. Time to check things out. Warm up the car and head for the highway. Car is as placid as usual. No change in driveability whatsoever. Did I get the correct box back?
Started up the entrance ramp to the freeway. Let the motor rev up a little. Boost gauge showing activity way earlier than before - bar graph starts shooting up at about 2700 rpms. Boost stays pegged at 1 bar - not just a poke at 1 bar anymore, it just stays there.
Open lane, hit the sport button, and accelerate up an overpass staying in 6th. Car pulls exceptionally hard. I'm at 135 coming close to turn in on a 50mph sweeper. Boost gauge is pegged at 18. I have never seen 18 before! Are my eyes lying?
Exit the freeway and do a U-turn. Go thru the toll booth at about 10mph and firmly mash the pedal. Holy ^$%$!!! All 4 tires spin and the car fires off like a catapult. My neck has just lost 30% of its disc height from jerking. Tachmeter swings wildly like the VU meters of old tape decks. Redline hits much earlier than expected. Time to snap off shifts and stop trying to look at the boost gauge. Keep the nose straight.
Slow down, breathe. Let the car saunter home. Pulse is still high. Brain is wild with activity. The promise has been realized. My 997TT is now like the Tin Man with a new heart-soul! Forget about the X50, the Turbo S, the GT2. This is all you need. For now at least....

mine used to hit 18 psi only between 2 and 4krpm but with the chip it stays there till 7300, is your car programmed the same?
Have fun and be safe the car is a monster now.

I am keeping the factory redline for now - don't want to push things too hard. I haven't been able to observe the redline with more that a few glimpses since the car is simply flying now and I am afraid....

also, try some racing fuel and you'll feel an even bigger difference in hp/tq.
Enjoy.

ECLou,
I travel to Houston about twice a month, is there anyway we could get together? I would like to hear the AWE exhaust. I am very interested in changing the exhaust and ECU on my 997TT.

nice post and thanks for the review.
you should consider writing for excellence or pca. and definitely Mike at awe should be paying you a commission for a ll the business you are generating for them.

UPDATE:
I have a couple of hundred miles on the car - almost all city and rush hour driving - since ECU install. Absolutely no issues whatsoever. It is as tractable as stock, if not better since the "lag" is cut in half once again. No crazy throttle modulation issues or jerky tip-in, no surging or stalling. Wife still has no clue after taking it for a few runs to the mall and grocery store.
Even better, I was able to repeatedly get FULL BOOST by 2400 rpm in 6th gear, and boost initiated at 1900-2000 rpm (sport mode). I always had felt cheated seeing the boost gauge finger spike up to 16# and then rapidly retract back to 12#. Now it stays jammed right to the edge!
