Eproms, ECUs, need data
My 110 is about to turn 100K on the clock, and is now 11 years old. I'm becoming more and more convinced that I have ECU issues. Hard starting, high rpm missfire at altitude, fade in power curve very noticable at 3200 rpm -- the latter two are intermittent. I've had these issues for quite some time now, and can't seem to totally debug them. Done fault tests, been through the whole disty thing, etc.
Please see the following I just found on a Google search:
"Re the power chip, you should check out the Unichip offering from APS. They fit a programmable chip and then put the vehicle on the dyno to program the chip to suit your engine perfectly. Also, there's enough eprom space for a 2nd set of parameters, for example, if you have LPG. So they can get a 2nd "map" to suit the two different fuels, and you just toggle the chip to
I'm afraid because of the calendar age of the vehicle I may be heading into a zone few of us have encountered -- aging computer chips and circuitboards. Maybe the UK folks have already encountered the problem and solved it -- haven't been able to determine that yet. This is one of the reasons I've been looking for clues about where to find a used back-up ECU. BritPac says that the 93 ecu and 94 are not interchangeable.
Has anyone found a good source, anywhere world-wide, for data about Defender ecus?
