So if you had another aftermarket management system you wouldnt need a crank sensor setup? Of course you would, a fixed setup like the Fiesta flywheel is not ideal either.

Basic ECU's use batch firing systems which do not require a phase sensor, when trying to get the best out of your engine these types of systems do not help. A sequential management system is by far better for many reason's.

Hence the reason that the cosworth management system works so well and for such little money.

Lets compare what you said about different management systems.

Cosworth L6 ECU £50-80
Cosworth Loom £100

Aprox prices..
Omex ECU £500
Autronic £1000
Emrald £450
Pectel T6 £1000
etc etc..

Looms custom made for any of the above £450

Now lets compare maping costs.

Cosworth £150 loads of tuners around the country

Any other ECU £300 - 500

So as for value for money i dont see your point?
