Just for the record I believe all spring-type .100 needles start with a B. So EDP needle may be BDP and be a bit worn (or BDR as you say). Beware of the automatic needle selection part of WinSU, I figure if it takes years of experience with SUs to select needles, a computer program aint gonna do it
Bearing in mind it has no selection for RE-13 cams, also thinks a 12G206 is the same as a 12G202, and also wont let you input what carburettor you have
Recommends an HIF6 for almost every engine configuration.
Other than that, the program is great for charting needles, I used to use it all the time when I ran SUs.
I'd also say if your SUs are going out of adjustment after a few weeks there is something seriously wrong that requires fixing. Never had problems with my SUs going out of tune.
BTW Kevin, you'll probably be able to knock those 800 needles down to a much smaller selection to choose from once you figure that 95% of them are wrong for your use
Anto.
