i installed my utec and some wierd things have been happening. First off, my current mods are; Hks Ti-Carbon Catback, Godspeed Downpipe, Ported waste gate, UTEC
Stage 1

when i start my car and it revs down to around 1500 to 500 the car kinda jiggles, like its not a normal sort of like a stall, in all it hesitates.
my next problem is around 3500 or when im half throttle in any gear around 3200-3500 rpms it will stutter, kind of jerk around. any thoughts? i know im supposed to be running stage 2 but it didnt come with that map.

Also is there a way i can load the stock map thru my computer?
PS. NO CELS @ WOT

Jesus help us... If you own a laptop please forgive my misunderstanding:

WHY-The-F do people who dont have laptops buy Utec's????????

Welcome to part thottle hesitation... you will find tons of threads on Nasioc and WRX hackers about part thottle hesitation.... Go read your Utec manual and it will tell you how to correct that.



oh wait... i forgot,,, the manual doesnt say anything about that. Call TurboXS.

borrow a lap top with a serial port to upload the maps to utec, since most USB won't work for uploading maps to utec.

you will need to have it dyno tuned to solve all problems.
the hesitate problem is the transition point from ECU to UTEC, you have to tune it out yourself and it takes alot of time logging and editing.

i gotta laptop

i switched it to stock map everything is fine now imma get tuned saturday, thanks for your help
