What do you intend to do with the S1 ?

I have an aftermarket ECU fitted which easily adjusts to give me a choice of running conditions. Thats simply all done by loading in a different "map" via my laptop.

The essential base running map is very very similar, but I then have different maps to do various different things. I may turn on the "fuel on over-run" option which will give me the flames out of the back if wanted it to (very very rare). Im more likely just playing with things like at what temperature the fans cut in. If I go to an event that is tight and twisty then the fans can be called in to switch on at a lower or higher temperature as required. I have maps which wont fuel the car at all above certain revs and use this as security.

At least I dont have to keep going back to my tuner everytime I want to switch about - so thats one option worth considering if your looking at that sort of thing.

The cossie management will work and it will keep your car running well if mapped correct, but if you like learning and developing and want some toys to play with then think again.
