Manes Posted February 9, 2023 Report Share Posted February 9, 2023 hi, I am starting to work on the link ecu in a professional capacity and I need information for the knock sensor on the HC92X version. I need to connect a bosch sensor and I see that the output is not wired which is a real shame. Can you tell me which card outputs correspond to the knock outputs? I suppose I could find the output by following the printed track of the HC96X but I prefer to have the information here. Thx for your help Quote Link to comment Share on other sites More sharing options...
RyanG Posted February 10, 2023 Report Share Posted February 10, 2023 I'm also looking for info on this. I just replaced the OEM knock sensor with a Bosch wideband sensor (factory is pin D3), before realising it's NC in the ecu. Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 10, 2023 Report Share Posted February 10, 2023 I can give some info if you are well experienced with PCB soldering, ESD practices and have a reasonably powerful soldering iron - say 60W or so. The stubs that you need to solder to are highly conductive copper/gold and set in plastic so you need to get the heat in and out fast before things go soggy. Note modifying the ecu may void its lifetime warranty. Quote Link to comment Share on other sites More sharing options...

I'm definitely not, but I was going to run through the instructions with a local guy who has done ecu work for me previously and see if he was comfortable with it. Alternatively if you are able to provide details to return to Link for this process and I can evaluate/plan for the downtime. Quote Link to comment Share on other sites More sharing options...
Manes Posted February 10, 2023 Author Report Share Posted February 10, 2023 I have experience and am equipped for micro welding (100w precision soldering iron). I can have the matches to add the option ? If is fitted properly can I retain the warranty? I will not damage the card by making a simple bridge between 2 pins. It would be a shame to have to install the hc96x with harness everywhere because of that... Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 10, 2023 Report Share Posted February 10, 2023 I will PM you guys both some instructions. If you want it done by Link you can contact [email protected] to get more info. Quote Link to comment Share on other sites More sharing options...
Manes Posted February 15, 2023 Author Report Share Posted February 15, 2023 Perfect thx! But I can keep the guarantee of the material as long as the work is well done? Quote Link to comment Share on other sites More sharing options...

Would really like to hookup my Bosch wideband knock sensor. Have 7 years SMD soldering experience and got all the right tools for this process.

ECU will be arriving tomorrow. Can't wait to set everything up! Quote Link to comment Share on other sites More sharing options...
