C400 JB4 QUARTER MILE TiMES
Spoiler
Filled the car up with Shell 93 octane and one can of VP Racing Octane Booster (so should be in the 96ish octane range)
last Friday and selected map 3 on the JB4. Used about half a tank of fuel over the last week. I did several hard pulls, both merging onto the interstate and from a dead stop over the last week trying to get the fuel tables to adjust (green wire is connected).
Best E/T: 12.692
Best trap speed: 113.86

Nice.
You were able to get the green wire connector to fit under the stock intake? I couldn’t get the intake back on with the additional connectors in the way. Not a lot of real estate there to fit everything.

Yes, it is very tight, I was able to just barely lay the pigtail flat beside the fuel rail, and when I put the air box back on it took quite a bit of convincing and adjusting. I just kept trying to turn, adjust the pigtail until I could get it "close enough."
