Not something I am a whiz at, nor do i have the time. I'm sure it can be done, but you need to somehow figure out a programming algorithm to help sort these out. It basically records every hex communication, and you somehow have to filter and identify PIDs which ar changing(indicating a measurement of some sort) and then you have to figure out what the measurement is and what the scaling is. There is a plug-in for Torque I think which allows you to port sniff the OBD II data stream. Sometimes these are found out and can be used by folks like Palmer, but it isn't very easy from what i understand.

However, the manufacturer apparently has many more proprietary PIDs that are accessed when hooking up their diagnostic tool. Not sure how familiar you are with OBD, but essentially the EPA mandates a certain standard set of PIDs. I am only using the PIDs that Palmer Performance has identified and provided in their extended PID package for Mazda. It will back off to about 50% advance by redline. The intake cam will only stay 100% advanced from 2000-3500 or so.

In 6th gear cruise at 65, you must try to stay below 60% engine load to achieve low 30's MPG. Best BSFC is 1500-3000 RPM at 80-100% load, with virtually no penalty for reving out to 3000. While my calculation method isnt perfect due to assuming a preset torque curve, it is very near something like a Prius engine. Significant throttling with higher cam advance. Any engine temp below 160ish seems to make it behave more like an otto cycle.

Anything below 50% is throttled, anything above will be controlled by the intake cam. Once warmed up, you will achieve 90-95% MAP (virtually unthrottled) at 50% engine load. I've made some general observations using this dash. I have one error with BSFC digital readout I need to fix with the current version, but should get that done tomorrow.Īnyway, if you are interested it is available here or if you search for dashboards using the tag'cx5' within the app.Ĭustom PIDs are here, and require the Mazda extended PID package from Dashcommand. Also, I have really only focused on English units and the 2.0 engine. It requires the custom PIDs I have created in order to work correctly. Avg MPG as provided by Dashcommand (they provide a fill-up 'learning' scheme to increase accuracy) Right now I have the following displays on the Performance page If you have any aspirations of achieving the best fuel mileage, this should be a useful tool. You can look at instant BSFC to understand the most efficient way to accelerate (basically 1500-3000 RPM at 80-100% load shows a consistent minimum BSFC). You can monitor things like Fuel trim and knock retard to make sure the engine is happy with the fuel you are buying. You can monitor the Atkinson cycle behavior (90-95% MAP at anything over 50% load) of the engine and tune your driving style to take advantage of it. Since the CX-5 is all about efficiency, I have focused on gauges for monitoring the efficient performance. I've also taken the basic 'Tuexedo' Dashboard and customized the 'Performance' page for the CX-5. I've messed around a bit and created some custom PIDs to calculate fuel flow, Inst MPF, Torque, Power, and BSFC all based on extended Mazda PIDs which are more accurate than the ones in the basic app.

In addition to all of this, you can create your own custom PIDs and Dashboards. Second is that you can look at a live virtual dashboard or a custom set of gauges which you can define. First is to do the typical reading and clearing of diagnostic codes. If you are not familiar, it basically allows you to do 3 things. It is similar to Torque, which may be a bit more well known.

I've been working with Dashcommand, which is an Android app for viewing and logging OBD data.
