Anyone tried the davis carchip on the HCH? It says it gives some standard data plus a couple extra channels. Well, my question is, what other channels of data are available from the HCH interface? Does it output mpg data or fuel consumption or something you could export and plot mpg with?

Also, just wondering in general how it's been useful to anyone who has used it.

 

It can only monitor 4 out of the 23 available parameters. Kinda cool though.

 

Hmmm, I didn't notice that. So what are the 23 channels then and do you get to choose which ones are monitored? I am hoping someone who's used one can chime in here.

 

I've been thinking of getting something like this too. I saw in their docs that they explicitly support 'hybrid gasoline/electric' vehicles. There's also the ScanGauge, but it doesn't do logging (although it does have a trip computer that tracks averages/max).

 

Where did you see that? In the exclusions pdf, it states:

 

I use a product similar but far more extensive on my GM products. It's called EfiLive http://www.efilive.com/ Unbelievable amount of data you can record; and adjust within your computer(s). I wish someone would come up with something like that for us HCH owners.



I’d like to adjust/control:

- The amount of battery usage before certain gas saving functions turn off.

o At 50% battery IMA is not used much at all, car goes into battery recharge mode.

- The amount of IMA used when pulling away from a light, or climbing a slight hill.

o I’d like to boost the amount used to full electric motor assist, uses less fuel to get car up to speed.

o On slight hills motor assist works, but only up to three bars, unless gas pedal is push much harder. Wastes gas, motor assist if needed should go to full scale, then fuel should be added after that.

- Control over when stop engine shuts down at traffic lights.

Don’t get me wrong I believe Honda engineers have done a great initial job setting up the program(s) in our cars. And the cars systems design is spot on for everyday drivers. But the programs appear to be very conservative. I believe more can be done to further enhance the systems our cars already have in place. Hope someone is able to come up with a product like I mentioned above.

It's for the Insight, but I'll bet it wouldn't be a big stretch to adapt it to the HCH.

 

I looked at that the other day. It really would be cool to have that for the HCH. It's a forum member that makes that unit, perhaps he can adapt if for HCH owners?

 

My goof, the sentence is under the "Non-Support Vehicles" section and I read that sentence too quickly.

 

Per website:

With CarChipE/X, though, you'll also be able to monitor any four out of 23 user-selectable engine parameters, including:


RPM
Throttle position
Engine load
Fuel pressure
Fuel system status
Short- and long-term-fuel trim
Battery voltage
Timing advance
Coolant temperature
Air flow rate
Intake air temperature
Intake manifold pressure
Oxygen sensor voltage
