I have used a few of these and I have one in my own car (1jz). It is a great ECU for the money, you get nearly all the features of the AEM, lower line Motecs, for a a great price. It has 6cyl full sequential ign/ inj, boost control closed loop 02 control, launch control etc..The new software is great and easy to use, I highly reccomend it. BTW we are a Haltech dealer and can get you what ever parts you want and great prices.
