At this point I'm at my wits end. A couple weeks ago my K-tuner was working fine, we installed a new throttle body and fuel injectors and now it doesn't work. It's the in ecu board, and is showing a steady red and blinking green light. Battery has 12.7 volts, every single fuse is good to go, every ground that I know of is good. Check engine light doesn't turn on then off when I key the vehicle on, and the immobilizer light is flashing. I have no clue what could be wrong, at this point I'm considering undoing 6 months of work just to have a running car.
Car is a 2005 Honda Accord, running a k24k20 build with skunk2 cams, springs and retainers, and throttle body; k24a4 block, crank, oil pan, oil pump and con rods; k24a2 pistons and rings.
Please help, K-Tuner not working
Re: Please help, K-Tuner not working
The LEDs actually mean the unit is working. You should check that the ECU is working by keying on without USB connected.
