Well gang...

I'm back to playing around with OBDII Data again. I'm wanting to move the ScanGauge II to the 1996 Dodge Ram and use my OBDLink LX bluetooth dongle for the 2002 Cummins. The OBDLink LX is basically plug and plug. The Android Software you can get off Google Play. Now as for setup there is a bit configuring. Make sure to fill in the easy stuff like year, make, model. Now the important stuff is the volumetric efficiency, engine displacement (liters) and select intake manifold absolute pressure. You see the 77.5% that is figured from the base line for Cummins ISB is 63% then my old ScanGauge II had a offset of 14.5% so adding together you get 77.5%.

So I took off and did a quick test run.

So the numbers look like they are close to right. I'm going to need to do a nice long haul and get some test data to verify number. As for my display I use. You can configure anything you want. I added warning zones and normal zones making easy to glance at it and see the needle in a lime green zone or not.

I dont know what is right, but my codes are there key on and after start. CEL on or not.The only other time i had something different was when the ECM crapped out. That was exciting to say the least. Another mystery of life I guess.

Hmmm I'm going to have to check now! Thanks Dripley!!

As for OBDLink. I found the Cummins ISB Volumetric number to be correct. Stock volumetric efficiency is 63% and you would "add" the percentage of offset to this number. Then as for other information, I'm working on displaying fairly accurate horsepower and torque numbers. So far its seems to be rather close. As for trip data I've ran into a snag that is rather depressing so some reason the App is failing out and shutting down. No error per say just "Sorry it's no longer working" message. So I'm working with the techs to see if I can resolve this.

LOL. I got to update nice to have your own Dyno.

 

 

I had to expand the "Torque" gauge I finally buried it at 1000 foot pounds. Also added Speed in the corner. Also expanded the GPH gauge...

 

The green zones I added to make it easy on the eyes to spot normal zones at quick glance. The HP and TQ gauges is normal stock power beyond that is extra.

Mike,

Could you easily list the ranges you set for torque, hp, coolant temp and intake air temp? I like what you did with each of them but don't know what they all should be for stock.  Also, how do you set up engine load? 

One other thing, I put teh vol. eff in and the brake spec fuel consumption. Not sure but does tq and hp gages need anything specific on set up to be sure they are reading correctly? 

Thanks,
Scott

For temperature gauges the max range is -40 to 240F. For All other gauges it's common sense. Like TPS is 0 to 100 percent. HP and torque is just run and see. Set a range you can work with.
