Guest |591| Posted February 11, 2011 Report Share Posted February 11, 2011 ok so i have my laptop connected, device manager recognized the vipec, drivers installed but now vipec software wont recognize it. i've manually set it to the correct com port to. the only thing that has changed from the last time i had it connected was its now installed into the car and i updated the software. the vipec has a blue light on btw and i double checked the connection on the vipec to usb.

rayhall Posted February 11, 2011 Report Share Posted February 11, 2011 I recommend you not select the com port number and set it to Auto. I would unplug the ECU from the harness and the USB cable from the PC. Then shut down the Vipec software. Plug in the USB cable and look at the device manager and see of the Vipec driver is listed. Run software again and press F3 to go online. I would also disable the AutoConnect for the communications. Ray. Quote Link to comment Share on other sites More sharing options...
Guest |591| Posted February 11, 2011 Report Share Posted February 11, 2011 so wait dissconect the harness then check device manager while the harness is still unplugged? can vipec be connected without power? Quote Link to comment Share on other sites More sharing options...
rayhall Posted February 11, 2011 Report Share Posted February 11, 2011 The ECU does not need to have power to check the USB is found. It is like all USB devices it will be recognized without power being on. I missed the bit about connecting the harness again and turning on the ignition before you try to go online again. Ray.

rayhall Posted February 11, 2011 Report Share Posted February 11, 2011 In the software read these to pages which cover possible comm problems. Help -> Contents -> Vi-Pec Tuning Software VX Tuning Software manual -> FIFO Setting Help -> Contents -> Vi-Pec Tuning Software VX Tuning Software manual -> Solving Communication Problems Ray.

Guest |491| Posted February 14, 2011 Report Share Posted February 14, 2011 lol sooooooo i just checked my battery and found out that i had 5V and now being on the charger it works and i got communication. ill slap myself with a fish later What was the problem here? I still havent figured mine out! (Was your battery flat?) Quote Link to comment Share on other sites More sharing options...
Guest |591| Posted February 18, 2011 Report Share Posted February 18, 2011 The battery voltage was to low for my vi-pec to work. So I tossed it on the charger and it worked fine. Quote Link to comment Share on other sites More sharing options...
Guest |491| Posted February 18, 2011 Report Share Posted February 18, 2011 Ok figured it out, since upgrading from 4.4.3 to 4.7.1 you cannot have both RS232 and USB cables attached. Even though the RS232 cable is not being used, it will stop the USB port from connecting. Quote Link to comment Share on other sites More sharing options...
rayhall Posted February 19, 2011 Report Share Posted February 19, 2011 That happened to me the other day. I had a dash plugged into the CAN/RS232 port. Rather then remove the cable at the ECU I disconnected if from the dash and found I could not get the software to go online. This is very odd. Now you have had the same thing happen, it is repeatable and not just me. I will get it fixed. Ray. Quote Link to comment Share on other sites More sharing options...
Guest |491| Posted May 1, 2011 Report Share Posted May 1, 2011 Hey ray this is still a problem in 4.8.0, can we fix this soonish please Quote Link to comment Share on other sites More sharing options...
rayhall Posted May 1, 2011 Report Share Posted May 1, 2011 Nothing to fix....anything (including just a cable) connected to the CAN/RS232 port will cause the USB to not work. The cable acts as a big aerial to pick up noise. Ray. Quote Link to comment Share on other sites More sharing options...
Guest |491| Posted May 1, 2011 Report Share Posted May 1, 2011 You are saying, you cannot have a dash connected via CAN/RS232 and tune the car with USB. real great! Quote Link to comment Share on other sites More sharing options...
rayhall Posted May 1, 2011 Report Share Posted May 1, 2011 It has always been the case that you cannot have the PC and a dash connected at the same time. I did at one time think you could unplug the dash cable at the dash end, but this cannot be done. The dash must be disconnected at the ECU before connecting the PC. There is only one communication channel from the main processor. The goes to the USB and RS232 components on the PCB. This is why you cannot have two devices talking to the processor at the same time. When CAN communication becomes available you can have a dash and PC connected at the same time.

Guest |491| Posted May 2, 2011 Report Share Posted May 2, 2011 Thanks Ray Only reason I asked, is previously with 4.3 I could disconnect the rs232 cable at the dash, but since upgrading. It now has to be disconnected at the ViPEC due to this noise issue. Which is a pain when its mounted somewhere not easily accessible, anyway bring on CAN.

Guest |518| Posted May 8, 2011 Report Share Posted May 8, 2011 Hey Ray I hope you can help me out with a USB issue as well. When logging, the time between samples is rather large (around .6 to 1.2 seconds). I'm quite sure the sample rate was much faster when I first got this ECU. I am logging to my laptop and using COM port #1. Any help with this? Quote Link to comment Share on other sites More sharing options...
