Yeah good point. Mine (RB30) basically got too dodgy to tune at 6000rpm, so I fitted the Autronic trigger and that kind of worked, but not too well because of how it's mounted. This one from Ross is far superior and during development as Paul and I have different ECU's the topic came up really early about it needing to be able to be used on a range of ECU's so they made the converter box that takes the signal and puts it into a 360 signal for PFC. Any ECU can be supported, thats the beauty of dealing with a company where you can talk to the boss - ring him up and have a chat and he can send you the part (or make it) to suit
