OBDII Laptop Software, Alex Pepper vs Harrison R&D

[BigDan]

I can decide between these two.



http://www.ghg.net/dharrison/ vs http://www.obd-2.com



I want a system that can provide the most info on my Cummins. Fuel Pressure is a must and instant gauge readings (being to do a test drive) also.



Being able to read and reset all codes also.



and last easy to use.



Thanks

I have this one. http://www.obd-2.com It works good for me. It will clear codes and does gauge stuff.

None of them can do fuel pressure. There is no sensor for that.

 

[BigDan]

The Harrison say's fuel pressure for diesels???? right on the front page

 

[SEmerson]

Not for 12 or 24v cummins. Maybe for someother diesels.

I've been hammering Alex Pepper about this. Seems that there is a great deal of program info that Chrysler/Cummins is keeping to themselves in regards to the OBDII capabilities. Obviously I have the Alex Pepper version (obd-2.com) and I am very happy with it. I opted for the tricom so I can use it on ANY OBDII compliant vehicle.



It does not pull that much info on the Cummins, and I don't think any scanner does for under $1000. But on all the other vehicles that I have hooked it up to, tons of info.

I wish they would call me back when I call tech support. Very frustrated with Alex Pepper right now.

 

[BigDan]

Hmmmm its still a toss up, Pepper doesnt seem to have that good of customer service.....



I just might go with the cheeper of the two... .

On the fuel pressure... the HPCR fuel systems have a pressure sensor for Rail pressure... that would be about it. .



Does anyone know if those programs allow you to do a missfire, cutout and relative compression tests for the VP44 and HPCR Engines??? (These are test we can on Deere engines that run a HPCR and VP44 systems. .

Thanks

The only thing that I have seen able to do that is the Snap On or the DRB the dealers use. Most of these programs you buy for your PC or Palm are just readers, not programmers.



Partyat33 - What trouble are you having? Maybe I can help, or soemone else here can.

Don't know if this is what you're looking for, but I saw this on AutoEnginuity's site:

"Bi-directional support. You have the ability to initiate system and component tests.

Mode 6 support. If a system test fails, now you can see the results from the failing component; not just the system. Our Mode 6 data is fully translated so you don't have to waste hours looking the scale and definitions. "

Stick, I would be glad to get some help. If you could post the proper gateway settings that would be a great help. Sometime it connect sometimes it doesn't. When it does connect it often disconnects before I can get what I want. And lately the digital dash does not work. I don't know why. Anyway, the right gateway settings would be a great start- then I can go from there.



Thanks

Check here



Check that thread... ..... should answer your question and get the dash working

For hooking up to the Dodge trucks (note - this will prevent connection to other than chrysler vehicles).



On the top menu line click Options/Gateway then the Protocol tab.



Uncheck the Default [SAE ISO] box at the bottom

Uncheck ALL the boxes on the left edge EXCEPT ISO-9141-2

Increase Timeouts to 10

Now the speed box for the ISO can be can be decreased to increase connection/communication speed. I keep mine set at about 30.



This is how Alex told me to set mine up. Whenever you want to connect to other vehicles, you will have to undo the above changes.



I ahve learned that if the program does not connect within 30 seconds, it will not connect so you will have to cancel it and try again. No need to close the program, just cancel the connection.



Now you can also set the program to only start recording when you hit the space bar when you are connected by clicking Options/Homepage then in the bottom left corner under Data Collection clicking the space bar box.



As far as the dash board, you first have to be collecting data on the Data tab, and I think the above link goes through that.

Thanks, I will check it out tomorrow. I crashed my car today so I guess the truck is a daily driver now. !!!

Ouch!



Hope everyone is OK.

 

[Partyat33]

Ok, got it to connect and stay connected. THANKS. As far as the digital dash goes you need to send all data as previously stated. However all the paramaters you want to send must be listed. So how do you get paramaters in and out of the data list. Not obvious to me. Also it says I have no codes, but I do have codes, and just for kicks I tried to clear them and they are still there. Key back and forth method.

PS nobobdy was hurt in the crash !

Mine does the same, won't display codes under the Code Page. To clear them goto the Status tab and clear them through there. That should take care of it, least it does on my truck?



I have Harrison's software enroute so I can compare the two soon. See which one I like better. Next on the list is http://www.autoenginuity.com if they get the Chrysler Enhanced like they say they will. I really interested in if the Speedtracer portion works for our trucks... ... ... ... ... .

Go to the Data tab, click on the PID Possible line then click SEND.



It will take about 30 secondes to pull everything it knows to pull up, then you can either click the ALL data line and click on the OK every time a "PID Not supported" box comes up, or you can do the manual way for the ones that I know will work.



OBD_STAT

LOAD_PCT (Load Percentage - how much load is on the engine)

ECT (Engine COolant Temp)

MAP (Mass Air Pressure - Boost - in inches of mercury - there is a conversion window under equasions)

RPM

VSS (Vehicle Speed Sensor)

IAT (Intake Air Temperature)

TP (Throttle Position)



Click on each one then click SEND. You might get lucky and have more sensors that will respond, this is all that I can get to work on my truck. After you have them all sending, click on Favorites and then save it. This way the next time you hook up, all you have to do is open the favorites and select this scheme.



Ditto what was said above for the codes. Read on the code page, clear on the status page. ENGINE MUST BE OFF!



The best way to learn is to just play around with the program and the different options. The enhanced menu item is different for each car and on each tab.

Thanks. Thats good help. I have been playing with it but sometimes you just get frustrated !!!
