Far more reliability, less maintainance required, better fuel consumption, often improved engine life and more power in many cases.

Why do people try and fault MAJOR improvements that make a Cossie much more livable with? If I had the choice between dizzy and rotor arm, and closed loop or just a decent chip ( which off someone like MSD is good in the first place) it is a no-brainer!

Yes it can work fine on the old system, but why not upgrade to a FAR superior method of doing things?

I have personal experience of it on a number of cars, including my own T4 saff with 850cc injectors, I just think you are being a bit blind thats all.! Big brakes aren't NEEDED, but are a huge improvement over the std jobbies

Think you ought to try it Pete, perhaps if you ask Stu he might do you a Daz doorstep challenge , and swap it back for free if you don't like it

I run C/L on T34, siemens 55's and Wasted Spark and so on, and I run 10.7 to 11,6 km/l doing all type's of driving from cue's, around town to doing 150 km/t .. and I'm quite happy with that...before I did around 9,2 to 9,8 km/l under same conditions ..... and no misfires
