I have a 2001 indmar 5.7L TBI engine. Can anyone tell me the baud rate that the ECM communicates at. I realize that Indmar uses there own scan tool but i am trying to communicate with a Snap on scan tool and it would be helpful to know the serial data baud rate. I have been able to get the codes out manually but i would like to look at the data as the boat is running rich
Thanks

If you end up not getting the information your looking for here to your question, Then you could also try asking the guys over at EFI University Electronic Fuel Injection Tuning Forums, Hopefully you can get Brian Macy AKA (TurboNova) to reply, as he seems to know his stuff pretty well.

But typically speaking, basic automotive scanners wil not read a Marine EFI system unless you're trying to build something special.

A good over all marine efi scanner to buy and use is from rinda technologies called the MerCruiser Scan Tool.

Good luck.

Thank You

I believe the baud rate is 8192 for MEFI 1-4 computers.
