We have a very reputable person on the site that already supports Motec in Dave Dahlgren of Engine Management Systems. Dave has done great things for many people in the LSR arena. Bike and car alike. Dave also offers good personal tech support, great pricing and an honest answer. You may not like what you hear, but his experience is priceless. He has helped me alot in my projects.
People think what they want, $2500 is cheap.... Consider the amount of time you invest in figuring out other systems, may a race or two at bonneville just to get things to work correctly, lack of technical support (as others have already suggested),
MOTEC in my mind has more of a proven track record, great technical support....
As another user has suggested in the past... "Set it and forget it...." race your machine.\
