S300 red flashing light, and cant upload

Post by jnoll6740 »

Hi, I am having the same issue. ECU with S300 installed is plugged into the vehicle, laptop is connected to S300, ignition is in on position, and the light at the top right corner of S300 is solid green. D1 is not illuminated and D2 is flashing red rapidly. S-Manager software will not give me any real time info on things like RPM, A/F, engine temp, ECT. I think it accepted a base map, but I'm not sure. Please help!

What is the serial number that is on the s300 board inside the ECU?

From Help, About, what is the version of software you are using?

I just tried setting the rev limiter to 1700 rpm. I uploaded the tune to the ecu and it was ineffective. The laptop is not communicating with the ecu and the ecu is not communicating with the laptop.

Also, The car is throwing a code but when I try to jump the connector down by the passenger footwell, the cel on the dash does not flash... Could I have damaged the ecu?

The S300 light sequence is as follows: Plug in usb cable to laptop, then to s300 -> D4 in top right corner lights up solid green -> D2 illuminated green for about 1 second -> then D2 turns red and begins flashing rapidly.
