I really do not understand the 'newer' argument as you are sticking this on a 20 year old car
I run cossie management with a brand new loom (Ryan Loom), a new coilpack, new injectors, and new sensors.. ohh and a second hand ecu,
I choose to do so as i felt the fact that the ecu was enough to power a high powered cossie it would be good enough for my CVH, and the fact that the fastest Escorts in the UK run cossie management suggests it is still up to the job
I like the fact that many people across the country can map it, if your 200 miles away from the specialist who maps your system, getting to him on a trailer can add to the costs should anything co wrong.
Another thing which effected my choice was that I wanted to run coil pack for a stronger spark rather than a worn old distributor, I also wanted to run water injection and air injectors. When you attempt to find another ECU with all these features for the price of a second hand cossie ecu you are hard pushed imho (well you were when I got mine)

But like I said, find your preferred mapper and then use what he is most experienced with
