If you want the short version you can stop here --> Unichip= AccessECU =



I have been running a Dyno tuned APS club spec for the past 2 years. I just had my ECU flashed with an off the shelf map from Cobb last Thursday, and all I can say is the difference is night and day. With the unichip I would have to give the car alot more throttle input before it would respond. With the AccessECU all I have to do is tease the throttle and away I go. With the Unichip the throttle was either off or on. With the AccessECU the throttle is progressive meaning more throttle = more go. With the Unichip performance was inconsistent, the car ran it's best when atmospheric conditons were close to the same as when it was intially tuned, meaning one day haul A.. the next Blah. With The AccessECU performance is the same day in and day out, at night or on a cool morning performance is a little better than it is on a warm day but, that goes with just about any car.

I could go on for days and belive me there is alot more but, I am tired of typing. Just get the AccessECU and you will not be sorry. Oh yeah Vishnu = $800 + $100 reflash. AccessECU = $400 + $20 reflash.
