I'm installing the beta KitCarlson FI and I'm turning my attention to tuning. I have access to a wide band O2 sensor setup for tuning in the FI part of the setup, but I'm not exactly sure how to optimize the ignition. My initial assumption is to install an EGT gauge. I would think this coupled with knowing the AFR would clue me into the ignition. There are so many factors I can modify that I'm having trouble keeping it all straight. Help me figure out what I need to do to get it well tuned. (IMG:style_emoticons/default/pray.gif)

I'm starting with the stock plenum. The only changes on the intake side are the throttle body is enlarged to 50 mm and I cut the snout off of the airbox and ran a 3" flex tube to the area above the relay board as a cool air intake. I'll look at manifold pressure and swap some things around later if it looks like I need to change things. Tim It's hard to resist changing things as conditions change especially when its so easy to punch a couple of keys and its done. The dyno I used before we used steady load and varied the RPM. After 2 months of seat of the pants tuning a little more than a hour cleaned up the AFR and I gained 1 and a half HP. Dave |
