Any updates for the Hydra Ems?

A couple of interesting things I was hoping you could point in the right direction of clearing up. Attached is a screen shot of OBD engine temp on the right and Canbus Coolant temp in the center. Any idea why they are different?

The other thing is the OBD tps shows up starting at 10% and the CanBus TPS doesnt even register. What is the preferred process for trouble shooting/editing? Also I will continue to post here what I learn, hopefully others with hydras will find it helpful.

Can mappings for the CANBUS side.

I messed around the TPS formula to get it right. For the OBD II TPS youll want RAW X 1.0 / 1.58 + -16.0

OBDII EngineTemp works well, I just switched it to F
RPM also works well as standard OBDII

I was not able to get the lua canbus logging script to work. I had the correct canbus channel enabled with the correct baud rate. I'm thinking this has to do with the ask reply style of the hydra. Can you help you with a script or an example of one I could try, given the information on the other page? Lambda would be helpful.

Hi,

Glad you got it working via OBDII.

Best bet is to find a student programmer or programmer type to help you do the request/reply custom Lua scripting for the Hydra.

Alternatively, you can ask the mfg if there are special PIDs that can be requested to get the data you want (lambda) over the OBDII interface. That might be the fastest option!
