Hi All,
I just added a turbo to my car and I'm using a wideband O2 sensor from Innovate Motorsport (the MTX-L). Every time I crank the engine I get an E9 error which is a low voltage error. Then the unit re-starts and enters heater mode for 20-30 seconds during which time it doesn't output AFR data. I've tried replacing the battery, better grounding, better power connection but nothing works. The voltage is dropping only down to 11V during cranking which I think is normal, but enough to error out the sensor. Has anyone else run into this? Any ideas on what to try next? Help from the company hasn't been very useful.
