I've been talking to McMark for some time about the MS/ignition upgrade. I decided to to take the plunge a few weeks ago and asked Mark to put it on his schedule.
Jeff (JSConst) had bought a kit from Mark and decided not to use it, so I bought it from him. All of the pieces are together and Mark has time starting on Sunday. Unfortunately, my time is limited so I may not participate much. I will add updates as I learn of them, or Mark may do that if he has the time. |

Here is the tune file that I'm using and a log file from a recent test run. The log file starts out idling, accelerates in low gear and shifts to 2nd.
Then the fun begins, you can see the bucking. It's interesting that the throttle position closes, but I have't taken my foot off the gas pedal. Is the TPS causing the problem or is it the effect. The engine is a 2056 type IV with a 9.5:1 compression ratio and Raby's heads. Has Raby's 9530 cam (Web's Cam #494), lightened flywheel and other lighter components. https://www.dropbox.com/sh/p593bw6iyebgwjn/bANp3X25ic Any help figuring this out will be appreciated by me and by those who will follow. |
