If you are running dual throttle bodies...where can you put a "fifth" injector for cold start enrichment or is there a setting in the software I'm missing? My 2.2 runs like crap until 210F.....which is about 5 miles at cruising speed.

Are you familiar with the sreen that has the Warmup Wizzard. If you have the WBO2 running into MS, it will show O2 on a bar graph. After the sensor heats up (~ 20 sec) you should see values for O2. it sounds like you haven't got enough enrichment. Enrichment can be increased in the bins to the left. It is in percent so 100% is no enrichment. On my rig I start at about 150% and taper down. Temp values end at 160 degrees. Dave |

Dave Wouldn't it be better to have the warmup run off of the oil temp sender? I checked my values...way low, 120% and down as temp goes up....I'll dial in some more enrichment and see how that works. |
