Jamez Posted September 7, 2022 Report Share Posted September 7, 2022 This started randomly happening a few weeks ago. I'd lose connection then after a few attempts at pressing F3 it would reconnect. Now I'm having difficulty connecting at all. I tried reinstalling PCLINK, drivers, uninstalling drivers via device manager, and using the driver folder to install drivers. I'm on Windows 11 using a GTRLink with PCLink version 6.22.38. Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 7, 2022 Report Share Posted September 7, 2022 Hmm, thats a very odd one. Im suspicious there maybe a hardware issue here. Can you try removing the ecu from the car and powering up on the bench, then trying to connect - just to eliminate power supply issues. You can power the ecu up on the bench by clipping power on to the big TVS diode like so: Quote Link to comment Share on other sites More sharing options...
Jamez Posted September 7, 2022 Author Report Share Posted September 7, 2022 Ok, before condemning the ECU I decided to go get a friend's laptop, downloaded PCLink and what I found was: KOEO, the ecu connection is totally fine and stable. However, KOER I noticed it would disconnect and reconnect every 1-2 minutes. I took the laptop outside of the car and placed it on the roof and from then on, the connection was stable with no drop-offs. This was strange as I never had drop-off issues back when my laptop worked, and I've never had an issue with EMI. As for the initial issue, I'm going to try a factory reset on my laptop with a fresh install of PCLink. Hopefully the drop offs were related to his PC?

koracing Posted September 7, 2022 Report Share Posted September 7, 2022 This is actually pretty common on the G4x. I often have to run the USB cables outside the car (MR2 where ecu is in the trunk) in order to get a stable connection. I've also found a powered (active) usb cable does improve signal integrity and retains connection better. After trying a couple I prefer the Belkin 5m active usb extension cable. This has better connection than just the link cable in most cases I've found. Quote Link to comment Share on other sites More sharing options...
