What kind of data is available when you "Scan" a HP500 EFI with Mercury's scan tool? Will the scan tool show overheat condition, overrev, hours of operation @ WOT, etc?
Thanks,

See http://www.rinda.com/marine/marine.htm

This is the tool for reading the ECU, This does not tell you everything but it gives you an Idea. The HP500 Uses the MEFI3 ECU. I cant remember them all but here are a few:

Hours
Volts
RPM
Coolant temp
any ECU flags set
IAC position
Throttle position
Knock sensor
Manifold vac pressure

there are a few others I cannot remember



The rpm hours is logged in the ignition module you would need the adapter to read these.

Ray,
Thanks for the info.

once you plug into and communicate with the ecu-it will give you engine hours-run time -run time 1000-2000 rpms,2000-3000 and so on up the scale to rev limiter -these parameters can be found in the service mode or gen specs-i use a laptop computer to scan mine but its all in there with your scan tool.

To my knowledge you cannot get stored rpm info on the hp500efi with a rinda scan tool. I have the tool with the latest software update and cannot access that info. You can get that info with Thunderbolt V ignition and PCM 555 and PCM 038. Somebody correct me if I am wrong.
