Megasquirt Info Thread

I have a DIYAutoTune built MS unit. I thinks its an MS2. I am also using a USB to serial adapter (eek).

I have the FIFO off so there is no buffer. I have tried both sets of rates (matching on each end). Com ports should be correct as well. I still wont rule out the cable but i have no access at the moment to anthing else.

Getting "no response".

When i turn the key to "on" i get a quick flash from the LEDs but none of them stay on. Should any of them remain on without the engine running? I have the wiring in the rear as per the mega manual with only the one voltage source from a switched ignition.

So...any thoughts? I have heard of having to flash the ECU with firmware (this has never been used prior nor have i had it communicated). But i can't connect to begin with.
