Your right there! Who would bother using an old dated ecu like that when you can get a bang up-to-date completely mappable ecu like MS, with all the knowledge and help that the ms forum offers, that can be repaired or modified DIY if something fails or if you change spec or car, it can run any number of cylinders and has all the options of other programmable ecu's. Im guessing you have not successfully used MS? it does take a good bit of patience, knowledge and skill, so prehaps is not for everyone.
