Beside the system has to be able to manage 3 trailings.
Bruno, this is my engineering based opinion and experience for you.
T&L timming split is not going to make as much power as firing them together. You can back this up by asking MASDASPEED, RACING BEAT, RE AMEMIYA, JIM DOWNING etc etc both for forced induction and n/a.
If you e-mail me I will send you scientific proof of this if these references are not enought for you.
Also here is a quote from one of my Australian counterparts 1000HP20B
"Why not run a Microtech MTX12 which has adjustable split timing for trailing every 500rpm, so not only does it have the split but you can change it from the normal 15 degree to ...lets say 5 degree up top in the revs.
Advancing the trailing timing closer to the leading is actually worth more power up top in the rev range. "
Now if firing them together is not an issue for you, then you can look at MANY good ECUs I would rate them in this order for support for you HALTECH, MOTEC, AUTRONIC, EMS (run by 20B user in Australia ROTORMASTER who is faster than all microtech injected "CARS (not rails!)" ! MAZFIX runs mechanical injection !)...All are first class units and ALL offer mucher higher tunning ability than the Microtech do currently.
You would be foolish to choose a Microtech unit as there is not the resolution you are after. PERIOD.
