For those of you that are running 4 CHT sensors under the plugs, what differences do you see between the cylinders?
Whats your typical temps for each cylinder with: A: Engine warmed up sitting at idle for a minute or two. B: Engine warmed up, cruising at 50-55 mph in fifth gear. |

Had a 40 minute drive today, starting with slower traffic and then a bit of 55 mph freeway in 4th gear before refueling after the winter and then a few minutes of 3200 rpm in fifth gear. CHT temps were around 285-290 for all cylinders except #2 that still reads in the 245-250 range.
Adjusting the throttle linkage and idle air seems to have smoothed out the temps over cylinders 1, 3 and 4 so at least a partial success. Hopefully I'll get some cruising tuning done in the next weeks and then enjoy a summer of more driving and less wrenching. On the way home we stopped at a local landmark over some 17th century field marshal and snapped a few photos. Its been so cold this spring that the grass has barlely turned green yet. First day this year with temps above 70 F. |
