    Ford Cylinder Contribution Error

    Running a Cylinder Contribution test on a 2001 Ford Ranger 4.0L, VIN 1FTYR14E11PA80325. As soon as the PIDS load up Cylinder 2 glitches to -35427 and stays on that number, other cylinders show proper data. My Verdict has Bundle 11.2 Version 2.1.0.2339.

    I switched to my Solus Pro with Bundle 11.2 and the data is correct for all cylinders including 2.

    With this test with the Verdict, you have to attach the USB cable to the S3 and unit itself. Not sure if that is your problem. Try it though.

      USB cable was attached, I started using it for Cylinder Contribution before 11.2 was installed, which informs you to use the USB cable. With 10.4 and no USB cable the Verdict would lockup during the CC Test, usually within the first 10 seconds or so. Ford CC Testing has been much more reliable using my Solus Pro.

        Do they plan on making that test wireless again or is that just the way its gonna be?

          what is the rasonf for a wireless module when you have to connect a wire to do tests?

              My guess is the USB cable is required due to bandwidth limitations of Bluetooth. Bluetooth 2.0 has a maximum application bandwidth of 2.1 Mbps compared to 480Mbps for USB 2.0.

                Dave is right. This is why AE no longer offers bluetooth with newer versions which support cc tests the bandwith is to slow. And I called aircable about making my usb scope wireless with bluetooth and he said the throughput would never support a scope so it makes me wonder how much data we might be loosing with the M2 module unless it is buffered and we aren't really seening real time on the display device which would make the zoom feature that much more important and is probably why no ignition scope or 4 channels.

                  Good thoughts, but if the Fords in question with Cylinder Contribution are using the CAN network, then the transmission rate caps at 1Mbps. I don't know, as I am not a Ford tech.

                    The M2 doesn't lose any data and works a lot like the Modis/V Pro/Verus as far as the scope data collection goes and what you see on the display when the scope is live. In the case of the Modis/V Pro/Verus, the scope hardware captures the data and only a portion is sent to the display for viewing when live. For example, if using a 20 ms sweep, there are 50 screens captured per second. If the screen is updated 5 times per second, the data is captured much faster than it can be viewed on the display live. Only a fraction of it is viewed live (1 of every 10 screens in this example).
                    When paused, all of the data that was continuously captured by the hardware is available for review.
                    The M2 is basically the same in this respect. The meter captures the data, but only a portion is sent to the display via the bluetooth connection when live. When paused, all the data can be sent to the display for viewing.

                      The problem with all these bandwidth specs is that they are all the theoritical limits, good luck achieving that in the real world, especially over wireless.

                      For instance I have several computers at my house, my laptop runs wireless N and is connected at a theoritical 300 Mbps, yet I can transfer files faster hardwired then wireless even though the identical solid state drives in each computer bottleneck the transfer rate under 300 Mbps.

                      Top that off with the hardware in a Verdict/Verus(mainly to keep the package smaller/lighter and battery life longer) and you run into even more bandwidth limitations. So far only the Ford CC requires the use of USB and it doesn't really bother me as it's not something I use everyday.

                        Wireless with Ford

                        Well as much as I hate to pour salt in the wound... my IDS to VCM wireless card has no issues, I even get a colored graph that is much more useful to use than what I get on my Verus 1, SO has a way to go to catch up in this area, I havent tried to use the new verus with wireless as yet, We just recieved two units at the college, I just opened them and set up wireless network but havent had time to test them due to being in the middle of finals this last week, would be so nice if SO could provide more tests like factory tools do
