I have read the key features quite a few times and there isn't much of a difference among the above. I drive a Mazda RX7 FD3S 20B (Triple Rotor-single turbo). Those interested, they can see my car in this video: https://www.youtube.com/watch?v=lWnsglyzAkQ
I have a Motec M84 ECU and I am actively looking to buy one of the above but I cant decide on the "Best" one.
Need help in deciding to go for one!
Cheers
Mir
