Is there a list of Live Data a guy should be able to read IF he has the correct reader?  I have an Innova 3160d (circa 2013), and hooked it to my truck.  I only had 6-7 pieces of data to view.  Reading the 100 page manual and visiting their website didn't help.

 

A code was set last night and I checked it this morning.  There was more data on the "snapshot" screen from when the code was set than I get when I push the Live Data button on my scan tool.

I'm willing to plunk down more money for a good gauge/tool/whatever, but first want to know what I'll actually be able to see.  No, a genuine DRBIII is not in the budget.  What can be viewed with a Scangauge II, etc.?  I seem to remember Mopar1973Man writing that he's gone away from recommending Scangauge, but I don't remember what the new preference is.

 

As a side note, should my TPS reading be at 11% when idling in the driveway, or is that an indicator I failed to calibrate the APPS after disconnecting the batteries at some point?

 

Since my signature is too long to be allowed:

2001.5 Quad Cab Long Bed, 4WD, Auto, ~275,000 miles

Almost "stock".  4" exhaust, ISSPRO fuel pressure gauge (5-12 PSIG), 200F Thermostat, 3rd 17" Gen wheels with stock-type tires.  Lucky to get 16.5 MPG, and I drive conservatively.

I'm moving back to Denver, CO in the near future and am considering starting my own business. I've been considering buying the $8k kit myself.

I'm thinking the same, nearly in a position to retire from Mobile Plant so a good light vehicle diagnostic kit and possibly earthmover/truck

I took the plunge and bought a Modis from the Snap On guy, brand new with 18.4 software, connected it to the truck to get used to it and up comes P1693, It has a seatbelt warning light on dash so this has to be why it has a 1693, no other codes so when I get time I'll check out the seatbelt system and find out what is the fault. Also includes all US content so win win. Just not the SCTM LOL

Also connected it to my work van, 2016 Ford transit, can do a lot more with that than the ram, just working on a webpage now to advertise plugins

I bought the OBDLink, as stated above.  Do second generation MAP sensors max out at 75 inches of Mercury?  That's around 8 pounds of boost here in Missouri/Kansas.  I know for the 'analog' gauge, you can set the limits of the sweep, but don't see any way of changing that for the Digital gauge.

 

Driving through the Flint Hills, the gauge was maxed out long before the steep part of each hill, and when I rolled into the throttle the turbo would whine a little more, the truck would accelerate, but the gauge stayed at 75 inches of Mercury.

 

I just want to make sure the previous owner didn't put in the wrong MAP sensor.

As a side note, I maintained 65-67 MPH for the vast majority of the 450 mile round trip and averaged 18 MPG, running empty but with camper shell.  Wind yesterday was negligible.  Intake air temp was a fairly steady 86 degrees.

MAP and boost reading through the OBDLink is not going to show correctly. Here is a video on the ScanGauge II I had.

 

 

Well watching that video just dumbfounds me.  It sure seems like once you hit over 14 pounds of boost, the MAP would read twice as high as when you were at idle, but it went from 28.3 to 37.  ?!?!?!?

I need to buy/make a boost bolt for my mechanical gauge so I can compare to the OBDLink's readout.  If the Link thinks a change in voltage is linearly related to MAP, but it's really exponential or logarithmic, I could see that making some weird readings.  But if the [PCM?] output is supposed to meet some OBDII protocol, it would be even more weird that it didn't meet that standard.  Actually, I take that back.  I have little faith that Dodge would have got all that right on the first generation of computer controls on a diesel engine!

 

Thanks for sharing, @Mopar1973Man.

MAP values read over the OBDII always look wonky like that.  The best way to read it is a mechanical gauge, because even if you plug into the data link to the ECM, you're only going to see 16 psi max.

I just used the LX on my Wife's Caddi.  I was able to chart the O2 sensor before and after the CAT.  I was able to determine that in neutral the Cat was working but when driving the downstream was tracking the upstream.  So back too it!

Newer the vehicle better the information. Like my 96 Dodge is extremely limited and most of the live data is odd. Like the 96 the MAP sensor is weird doesn't show real manifold pressures. So key on engine off it shows a weird minus pressure which should be vacuum but should be close +12.0 PSIa.

 

Like the Cummins the MAP sensor doesn't report a real number either. I've documented that long ago.

Mike, were you ever able to get the LX to offset and read the actual boost?

Yes. Not too much information with my snap on modis on 18.4 on my 98.5. 98 3500 v8 is ok too. 65 plate ford transit work van on the other hand is fine. Newer the better. Got a 04 hemi 1500 with a misfire to check, that will be fine
