CJ-Howell install finished, impressions.
I got the Howell TBI fuel injection system all buttoned up on my CJ-7 last night and got to take it for a drive. For those who didn't know, this was a replacement for the Carter BBD on my '83 with a 258, auto.
The kit was pretty easy to install, the scary part was reading the instructions where it said "cutting" and "Splicing", but this was just to run the electronic ignition outside of the factory computer (the Howell computer does not read or adjust spark). Almost all of the vaccum lines were deleted and all vaccum switches except for the CTO valve (to operate EGR and charcoal canister purge) were eliminated. It's sooooo clean under there now!
The instructions were perfect! One spot where it said to "Cut the rest of the computer harness from the main trunk", all that was needed was to unplug the harness. At the end of the weekend, the fuel pump running all the time was the only flaw (see service impresions).
I sent and E-mail to Howell about the fuel pump problem, and then called them on monday to rectify it. They didn't get back to me on tuesday, but wednesday they had a call back to me. It turned out to be two wires switched around in the supplied wiring harness. Very easy fix once it was diagnosed.
WOW! The Jeep has never run this good. It starts cold and runs IN GEAR without my foot mashed halfway to the floor on the gas pedal to keep the BBD chugging away. The motor feels new, and has not had this much smooth power since I owned it. After the computer settles in, I will do a fuel mileage test.
I would recomend this to anyone struggling with that old Carter on their CJ/YJ. It was a fairly easy upgrade that will be a joy for years on my Jeep. I do not regret spending the money. If anyone has any questions please feel free to post here or send me an e-mail.
