It is possible that the regulator and fuel pressure is fine, but there is a problem in the fuel enrichment settings based on temperature sensors. I have found that the engine coolant sensor is for short term enrichment. It has to do with enrichments for starting and warm up. The fuel map should only be tuned when at normal operating temperature.

This thing is stupid simple. The only sensor it has is the TPS, the coolant sensor, and pressure regulator. You can buy an optional O2 harness, and I in fact found one fer cheap on 'th bay

For now, I temporarily wired the temp sensor to ground through 200 ohms, a warm sensor. There is no charge temp sensor.



By the way, how do you insure the lack of a ground loop problem on a one wire (Bosch) O2 sensor? I was thinking of welding a steel tab onto the tail of the collector, silver-brazing a chuck of copper to that, and grounding it to the frame rail, and then pull a shielded O2 wire from there.
