Where is the best place to begin learning the Hydra software? I bought a car with it already installed (V2.7) and I want to learn as much as I can before I start diving into it.

It came with the FMII kit, so I'll be talking to Jeremy next week for some tuning help. Was hoping there were more resources to learn from. Youtube videos are scarce and not very good for the Hydra.

Edit: Just found the Hydra forum on their website. It is filled with spam they don't even care to delete. Is this company still in business? On their firmware page, "This page was last updated onDecember 11, 2013." Seriously?!?!

 

Jeremy and the documents he's written are the best starting point. The Hydra isn't actually all that different in concept from most other modern ECUs, though.

Thanks! Are his docs available on the web or by request only?

 

The company is still around, although they're for sale last I heard. I'm a big fan of Hydra for certain applications, and the software is fairly intuitive. Seems to be great at start up, with better idle and throttle response characteristics. For someone that likes to fiddle with their tune, MS is probably better suited. For instance, you can't use bluetooth with Hydra, and I don't think it has CAN out either.

 

I seem to recall FM talking about controlling NC CAN gauges with a Hydra, which would suggest it does have CAN out, but I don't know for certain. I used 2.5 and it had no CAN support at all.

As far as FM docs:

Just searched in ECU pinout, yup, GA03 and GA04 are CAN hi/low. Cool.
