My question seems somewhat basic compared to some of the other things I have read but it is still kicking my a** so I need help. I have a G4+ PnP in my Evo 8. It is running the Link CAN Lambda module and I am also running a PLEX SDM-300 screen. Ever since I had the car tuned, I have had dramas with it missing and stuff and we've logged data and found little bits and pieces but now we are seeing random spikes in the RPM between 10,000 & 20,000 which is causing it cut ignition and pull timing etc. Trying to be thorough I decided to check my Cam and Crank sensors, I pulled the connectors apart, cleaned them, made sure the wiring was ok etc.
After reconnecting the sensors, I put the key back in the car and fired it up but no data was streaming to my PLEX dash although it was powering on and I was getting nothing registering from my lambda sensor. I took the car around the block just to make sure everything else was still working and it is, all my other sensors are working.
I went into CAN settings in PC-link and noticed that both channels were turned off, I turned them back on and then went to scan for the devices but it keeps telling nothing can be found
I have tried the following steps to resolve it
1. Reload the most current tune
2. Reload the previous tune file
3. Reload firmware
4. Revert to default tune as supplied with the ECU and reload current tune
5. Pull out wiring and confirm everything is still plugged in
Nothing has worked so far, the fact it is powering the dash is what confuses me, obviously there is power being transmitted but just no data.
Pretty open to suggestions at this point
