Hey guys.

Installed the S300 and all the jumpers and sockets in the the right locations. Problem im having is 1 Im getting a solid red light and the car will not run.

I can see the ECU online in the left corner of the HD screen. I can upload maps onto the ecu.

But the ecu is still in red and i can not see any sensors when i log into the HD screens. Anyone????

This is a EG coupe and a PR4 Ecu and S300

It's the socketing. Double check each pin for cold joints, bridged joints or any lifted tracks.

Yeah i did that already checked each sodered joint. im gonna re do them this weekend any try it again. Cause we plugged the ECU in and went for a drive and it ran fine.

Red lights means what tho exactly?

Red light means that the s300 cannot communicate with the ECU. If the car runs ok, then check that J1 is in place.

Im having the same problem. I tought it was the ecu, i took my s300 out and put it in another ecu, same problem. I then installed a friends s300 in my ecu and it worked perfectly. Something is wrong i just cant figure out what it is any suggestions?

What versio of software are you using? What happens when you go to File, New and upload a new calibration to the ecu?

For me, it does the same thing. Im not 100% sure what version im running,but i will install the new one this week and see if it works.
But i know we put the s300 in another ecu and car and tried to get tuned and it wouldnt work then eighter, any suggestions?
