OOPS, I guess this one hung up in the filter somewhere! sent it out a day or two ago. Must of needed a moderator to release it. Probably the wrong forwarding format? I checkd the numbers with google search and found the top three as valid ecu numbers form a rebuilder, but they showed them as "federal". That make sme think they crossed them over to state side ecu's that use O2 sensors? The bottom two numbers don't come up on a Google search at all. I'm only mildly curious about this so I didn't take it any farther. I'd be interested in having one to play with should it be economicaly feasible. I don't really see much point to it unless you wanted to run your enegine on leaded additives and things that clog up O2 sensors. For the most part O2 sensors do a good job of keeping OBD I in line. Putting one in is not that much of an issue. -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 -------------- Original message ---------------------- From: Wrambler242@xxxxxxxxxxx > -------------- Forwarded Message: -------------- > From: "Dino Savva" > To: Wrambler242@xxxxxxxxxxx > Subject: RE: Jeep Ecu > Date: Tue, 3 Apr 2007 19:40:43 +0000 > > Unfortunately the sticky label with the part no. disappeared a long time ago > > so I don't know what it is, but I've found part nos. of other '91-'93 4.0 XJ > > computers for a manual tranny that are suitable for leaded fuel so obviously > > they don't have O2 sensor feedback control.
