ANy of you guys ever hear of these folks: http://unwiredtools.com/utcis.asp Seems as the WUR's for our cars get scarcer these guys have a programmable unit that goes into the stock WUR location. Although they focus on MB's, if the pressures are a known entity, I think these can be programmed for F-Cars as well Oleh
See post #9 http://www.ferrarichat.com/forum/showthread.php?t=256884&highlight=WUR I believe he rebuilds WURs for about $250 or so. About half the cost of this unit.
Looks interesting due to its tunable characteristics. I don't doubt that it would work fine as a replacement WUR. Whether it's worth the price...who knows? If a stock WUR can be rebuilt as new for 1/2 the price then perhaps not. But the tuning capabilities might make it worth the money. It would be nice to have an independent test of the unit and what improvement, if any, that it can deliver. A few minutes later...found this: http://www.youtube.com/watch?v=ETWhIaGzfUI&feature=related
