I hear you Lou. In my case, I was willing to take things in small steps, take my time to absorb and study the results before making the next change and do my final real world tuning at the track, in the process, making myself look like a nut case until the major pieces of the puzzle fell into place. It's not like I had a lot of people to bounce ideas off of with the setup I was trying to make work. But man, it feels mighty good to be over the hump now.
I played with the idea of renting a chassis dyno for a day. Got some offers from friends with dynos to use it for a day or two, but decided that it would not be the proper atmosphere for me to be productive, being under the gun to get it done. I had to revamp the fuel slope so many times, re-building the entire fuel map each time I did that. That in itself is very time consuming. I would have been burning money and not getting use out of the dyno. Besides, there is nothing like a tuneup done in the circumstances the engine will be used in. From what I have gathered from other tuners that use chassis dynos, you always will need to make final adjustments on the road. If that was going to be the case anyway, I just bypassed a step that would have made things a little quicker for me. Maybe.
