Here is an update on the Fuel Injection changeover. It ran great on initial startup and it's first short trial run. The next day I fired it up and took it for a longer ride to start the self learning process. The more you drive it, the more it learns about how the engine responds to changing conditions based on the input from all the various sensors and it begins adjusting itself to run better. The more you drive it, the more it learns. You can also fine tune it yourself with the handheld device or a laptop computer. I took it over to Auto XTC and John put it up on his lift so we could inspect the fuel lines on the undercarriage, and everything was fine, better than fine.
Then I went to start it and it acted like it was flooded. Had to do the pedal to the metal trick to get it to start, and boy did it blow black smoke. It was really flooded. Took it back out on the road, and it was not running right at all. Idle was at 1100 rpm and in some cases higher, exhaust popping on decelleration and a lot of hesitation. It appeared the self learning process did not go so well on the first extended drive from my house over to Auto XTC.
Got it home and let it sit for a while. Went out to start it and look at the computer numbers, and it was flooded again.
Contacted FiTech Tech Support and they asked me the version of software it was running. I told them and they said it was not the correct software. They emailed me the newest version of the software and the instructions on how to installed. It was real easy. Plugged the hand held unit into my computer with a USB cord, deleted all the files in the handheld, copy and pasted the new files into the handheld and it was back to the original setup using the newest software.
I had to input all the setup information like engine size, cam, idle rpm, etc. There was also a setup procedure to adjust the IAC (Idle Air Control) to the correct initial value for my engine. I did that and it started right up. After that, the computer did the fine tuning on the IAC.
Today I took it out for a test ride and it ran GREAT. No hesitation, no exhaust popping, no fast idle, everything was great. When I stepped on it, boy did it respond. MUCH more than the carburator ever did. I drove it for about 5-6 miles around the neighborhood and back home, as it is suppose to rain today and I did not want it out in the rain (no door window seals, no drivers side window, etc.) Amazing what a difference the updated software made. My guess is that it left the factory to the distributor with the older software and they upgraded things after that.
The only adjustment it needs, and there are instructions for it that are real easy to follow is for decelleration. When you take your foot off the gas pedal, it does not return to idle quickly, but drops to an idle slowly. Not bad at a stop light, but really noticeable shifting gears. Once I adjust for that I will take it out again.
Funny when I was test driving it how many heads turned as I went by. The C2 really gets attention!
Well, that brings things up to date so far.
