Never heard of it, didn't pull up in any google searches. It looks like whatever tach I get I need it to wrap around the coil wire as I don't know what and if anything is prewired. I settled on the Tiny-Tac, paid less than $40 including shipping. Onlything that bums me out is the 2.5 sec latency and the fact it only goes to 9990 RPM (about redline though)
My searches took me to chainsaw and cart racing forum web sites. I did find the
SenDEC Race Pro II and it looks good but it's out of my range at $300
