Got ECU reflash today!

i found this to be the most worthless mod. you basically pay for a higher REV limit and fuel cut point. the way i see it, if your going to reflash your ECU, do the tuning at your local or a near dynameter. this should be done because it DOES matter where you live in terms of A/F. i know many people who have had to return their ECU for reprograming. does anyone know when the stand alone AEM unit is coming out? i have the AEM EMS unit on my supra and s2000 and find this to be the best bang for you buck in terms of tunability and flexability.

it could rebel riddick style

i feel for 600 bones id like to be able to say i got something for my money. i cant even hold in my hands what i bought. well maybe...but not like you would if you bought say an intake or something that REPLACES an OE part.

I have to disagree with you. I have the Technosquare reflash with the Crawford package (plenum, headers and cats) as well as an intake and exhaust. Before having my ECU reflashed my car had a very rough idle, even after my dealer raised it. After the reflash my car ran sooo smooth and had more power. I have had absolutely no problems with my reflash for almost a year. It seems to link all the mods so they work together.
Obviously individual tuning is the best way to enhance your ECU, but that is not readily available in most places.
Hmm thats strange..I know a lot of people that havent had a rough idle after all the wonderful crawford products..anyways like everyone else has said [$$$/physical improvments] ratio isnt very appealing to most.

Interesting. Nobody knows the difference. So far everything that has been posted here are speculatory and/or psychological results on the differences. Anybody have any hard evidence of the differences or is it all hearsay and assumptions?

in a race to 120 from a 35 mph roll with a stock z where i had an intake, exhaust, cats, plenum, i consistently only pulled a few feet against the other car. all the time, any time we raced.
after the AAM reflash i am now pulling ahead about 2-3 car lengths against the same aforementioned opponent consistently. all the time and any time we race.

I never had any major idle problems until after I installed my plenum although with each prior mod the idle got worse. Prior to the plenum I had an aftermarket intake, cats and an exhaust. I had been researching the reflash and then the service manager at my dealer who installed most of my mods suggested that I get the reflash because he had seen similar problems on another highly modded NA Z (with an intake, plenum, cams, headers, cats and exhaust). He has a 350Z too by the way. After that car got the reflash it ran like new again. Once I got the reflash so did mine. And it continues to run fine to this day, almost one year later. Since I have the Crawford package I got the Crawford reflash. My results with regard to the idle issues are real, not subjective.

ok...
my point was that exactly. although you may be happy, someone else could buy this and experience what others have. therefore- localized tuning is perfered; how do you know your getting every bit of power from the tune? you could potentially gain more by tuning it where you live. see what i mean, i dont pay 600 bones as to whether or not my ECU tune MIGHT work....too risky.

After the reflash my car idles better than it did when it was brand new and totally stock. Smooth and at a constant rpm.

What I am saying is that "pulling by several car lengths" isn't a viable measurement as there are too many variables introduced with the driver. I want to know what are the quantitative differences between the AAM and TechnoSquare reflash. Dyno numbers on the same car? How is the fuel map different?

What needs to happen is some friendly competition.... right now technosquare/AAM seem to have the market cornered on this.
I'm gonna call the nissan dealership later today and find out how much an additional ECU for 2003 Z's are.. I'll start there since I own an 03. I think that there were some changes iin the 2004.5 ECU's.
I know the ECU is encrypted.. but it should not take too long to crack with the right tools.
Setting a new rev limit shoud be rather easy, once I've located it.
I'll need help with the fuel maps once I have found where they are at in mem. Any takers? Also will need cheap access to a dyno.. maybe the guys at ultimate?
I am seriously considering this... and ... selling a full flash for only $100 (its true value in my eyes).. if not giving it away at meets..
I would not be doing this to make $ and I could use help from my fellow geeks out there..
should I start a new thread on this?
