If you haven't purchased yet you might want to wait a few more days. I have been working on it off and on since Friday and am not impressed with the results at this point. AFR display/logging drops out, it seems at about the rpm range that the power valves operate, may be DC power-supply issue. The RPM inductive pickup is totally inoperative, on sled and another 4 stroke engine I tried it on. The wired RPM input has been very flakey (unusable) so far, am waiting for stores to open after holidays to buy a variable resistor and try and find a sweet-spot that satisfies the LM-2's RPM input requirements.
