PLX Wiki Wi-Fi and Rocket ECU

PLX Kiwi Wi-Fi and Rocket ECU

Just got a PLX OBD-II adapter and the iPhone app DashCommand. Works great on my two Ford vehicles and wanted to do some data logging on the rocket.

Even though the box says it it compatible with KWP-2000 protocol, I can't even get the adapter to power up when I hook it into the OBD connector on the bike.

Anybody try this gadget with any luck? The Rocket OBD connector only has 3 wires and I wonder if I need to separately wire up power.

DashCommand is a great app that lets you see realtime what is going on with timing advance, fuel flow, temps, fuel rail pressure, MAF, and MAP, torque, HP, etc. You can record the data on the phone, email it to your PC, and then import it into data logger software.

I was able to log data from my truck and then play it back using the PLX logger software. Very cool stuff. This will be a great diagnostic tool if I can only get it to talk to the Rocket OBD.

Any tips appreciated.

I connect Bluetooth unit to my ECU, no problems with power.
Can you set pins on your unit?

The downside is BT (crap), I can connect and get most data from ECU, but lose connectivity while driving

Will go for WiFi as well, but I use Android

Got the plx kiwi wifi working tonight. Found out from the rat site that I had to jumper pins 4 and 5 to get the device to power up. Not all PIDs got monitored, but dascommand did detect MAF, MAP, fuel flow, rpm, ST and LT fuel trims, IAT, coolant temp, gear selected, and engine load. A/F ratio and lambda are not directly read, but it will calculate a/f from o2 trim, fuel type, fuel flow, and MAF.

By entering final drive ratios, weight, and tire size, the application will calculate HP and torque from the accelerometer on the iPhone or iPad.

You can store the data log for your ride and then import and replay using PLX logger software.

With a full list of Triumph PIDs and scaling factors, you can create custom parameters to monitor beyond the defaults.

This is potentially a very powerful tool for live dyno tuning on the road. Imagine being able to do a track run, log the data, tweak a tune in TuneECU, download, and repeat the run. With enough effort one could optimize each cell of the L and F tables for economy, power, and eliminate decel popping.

Need to do some more testing, but that's the early review for now.

Very interesting, I can not wait to read more!!!

Good work! I will get a wifi unit and try both iPad and Android, the Android app can store log data on the cloud, time to update Ironbutt's paperwork to 2011. Now we need to find the R3's OBDII complete list, like sidestand down, gear etc. Can you pls check if you can build own lists on the iPhone app.

After searching through the PLX support forums, it appears you can no longer configure your own PIDs through the iPhone app. At one time, this may have been possible, but the forum posts sound like it got scrapped in the final version of the DashCommand app.

However, you MAY be able to setup your own custom PIDs using PLX Logger or Scan XL from palmerperformance. This will only work for a laptop based datalog. Also - - To be able to get a live datalog into PLX Logger using the PLX Kiwi Wi-fi, you need to shuck out another $100 for a license. Not happenin'.

For now, I will stick with emailing the log files and importing them into PLX logger for replay.

I was able to record a short log file and successfully import it into PLX logger. Unfortunately, the jumper vibrated lose and I lost power shortly after the trip started. All I got was 3 minutes of warmup idle in the driveway. GRRR. Will try a more robust connection and do another performance run.

The application DashXL is a free skin editor for DashCommand. You may be able to configure the PID through that interface. So far, I cannot get A/F or Lambda to show on the standard skins. Need this to do some fine tuning to the fuel trims. Haven't got that far yet.

Stay tuned . . .
