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. |

Target lambda is around 0,92 (8% more fuel than lambda 1.0) But at the moment I'm not using the lambda control function since thats not been fully mapped. Running off the VE and Ignition tables only. Screen shots below. This is only the map from the dyno. We still need to get some street fine tuning done especially when cruising.
My injectors were flowchecked and the results were at 3 bar of static pressure: 369, 369, 369 and 377 cc/minute. I'm not sure which injector is on what cylinder but if the 377 one has ended up on cylinder 2 that could contribute to the lower temp but its still a mystery why it would flow less air. I did set all the valves during the winter when I had the engine out. I can try and swap the #1 and #2 cylinder injectors and see if that affects anything. |
