Zeine89 Posted May 19, 2022 Report Share Posted May 19, 2022 Hi guys My ecu was connecting properly for the past 6 months I’m running e85 on my evo so I had to check ethanol content in my fuel but I get the following notification on my laptop unknown usb device I tried everything there is to connect no luck keep getting error 43 on my device manager my question is: is it possible to connect to my ecu in any other way? is it possible fixing it at a computer store ? and how long would it take shipping it from UAE to NZ and back cuz I have a speed event in a week, I believe my usb chip is gone bad and I can’t send it to NZ at the moment I’m running out of time pls help Thank you best regards zen Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 19, 2022 Report Share Posted May 19, 2022 Yeah I would be suspicious there is a hardware problem in this case, I don’t remember seeing this type of error message before. It would be a good idea to try plugging in to another pc however, just in case it is a windows issue. What ecu do you have? Some of the G4+ ecu’s can be tuned with a serial port connection - you would need a usb to serial adapter tho and probably make your own cable Quote Link to comment Share on other sites More sharing options...
Zeine89 Posted May 19, 2022 Author Report Share Posted May 19, 2022 Hi Adam I tried connecting to my tuner pc same thing if you have a pic or a link to that cable please let me know my ecu is the g4+ (evo8+) thank you so much Quote Link to comment Share on other sites More sharing options...
koracing Posted May 19, 2022 Report Share Posted May 19, 2022 You would need the CANSER cable and then move your USB connection 5 pin cable from the top board to the CAN1/RS232 plug on the bottom board inside the ecu case.https://dealers.linkecu.com/CANSER_2 Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 19, 2022 Report Share Posted May 19, 2022 If you cant get a CANSER locally then you could make your own as below. Quote Link to comment Share on other sites More sharing options...

Adamw Posted June 2, 2022 Report Share Posted June 2, 2022 Sorry I cant really see the wiring connection well enough. Do you have 3 wires connected? And the connection is to the CAN1/RS232 port on the bottom PCB? Are you using a USB > serial adapter? Can you give us a picture of the windows device manager Com port section.
