I recently purchased a link g4+ plugin ecu for my r33 rb25. Got it tuned and running perfectly for the past 3 weeks. Yesterday my wideband suddenly registered rich 10.0:1 afr ( dead time went up bcoz of low voltage ) and voltage on +12v internal shows 8.9x volts. Ignition on the check engine light is dimmed and the Motorsport functions are all no working. Upon checking the ecu is outputting around 9v on pin 49 & pin 59 with the eccs relay unplugged and ignition on. Any ideas?
