Just got back from the Dyno. We were able to tune the mps reasonably well. Still have a little leanness at wot and lower rpms and richness at wot at high rpms but overall pretty smooth. Waiting to get the figures from the shop. If I remember right it was 77 horsepower and 105 lbs of torque at the wheels. I am running big 225/50r16s so I suspect I would pick up some more with lighter stock rims and tires....
I will post the graphs as soon as I get them. |

Finally got the graphs! I am color blind but at least I can figure out the last run was the best. I am now thinking about maybe spark issues up high. I am still running the ancient coil (123dizzy) and perhaps that is too weak and worn to keep up? It's got a little over 3ohms but I don't know if that means anything about spark strength at rpm.

If you could get the AFRs stabilized and dialed in there are a couple more horses hiding in there. Every one of those runs is lean down low, a couple lean enough that I would be worried about head temps, then all runs but the red one go overly rich above 4k rpm |
