I've fitted both a 14CUX injection system and later a thor injection sytem V8 to my LR 90 and in both cases used a 3.9 in tank fuel pump within the LR90 fuel tank. The 14cux is similar to the GEMs in terms of the both have a inlet manifold pressure controlled fuel pressure regulator and a spill...

Input from engine ecu via becm: Engine speed 12v square wave. H gate is only for displaying the gear position or for switching to sport mode. It does not switch the high/low, so you can get away with no h gate and use a simple switch for sport/manual mode. The torque convertor lockup is...

Have a look in the P38A workshop manual, there is a lot more info in there.

To have it working as a full automatic, then you need the g/box ecu, but it requires an engine speed signal from the engine ecu and if you loose this signal it defaults to 3rd gear. You also need a throttle angle signal from the engine ecu to get the kickdown to work properly. It would probably...

I presume that you are only thinking of fitting the short engine from the 3.9

Yes, no oil in the dashpot will make it run weak, so do that first. Have you got none std air cleaners fitted as higher flow aircleaners will result in the engine running weak when the engine is underload?. Make sure that you have the correct needles fitted (they have 3 letters stamped on them...

Can't help you with that question. I originally removed the old mechanical fan and shroud and fitted 2 condensor fans (hoping that they would suffice for engine cooling), but they did not pull enough air through to keep engine cool on a hot day. So I then bought another mechanical fan but could...

I used to work at a Landrover dealership as an electrician many years ago and have changed many becms, so know the pitfalls of changing a becm. I also remember (and this ties in with what you heard) and that is the service becms were all high lines. High lines will work in a low line vehicle...

Had a quick look through the previous comments and could not see if your vehicle had a hi-line or lo-line becm. Does it have a H or L on the white label above the becm fusebox. Changing becms can be a nightmare, so would recommend that if your becm is working fine, then leave it alone. A becm...

The vehicle was designed to be driven around in 50C ambients, so cooling system will cope with that, therefore its overkill for UK (if rad is not blocked), so making it less efficient by removing the shroud should not be a big issue in the UK. I have a 4.8 V8 with a std mechanical fan & rad with...

The factory fit Lo-line becms did not support front fog lamps. If anyone has fog lamps working via the becm, it's a hi-line becm (even if its labeled as a lo-line). Activating the front fogs via the becm programming will switch on the bulb failure monitoring for the fog lamps, but as Johnnycash...

I would get the connector issued sorted on the front passenger door before trying to diagnose problems with the drivers door. The latches aer prone to having water get in to them and you can have numerous differnt problems with them. I've never reworked them but there are numerous threads on...

Ooops yes, you are correct the CAN-bus did not come out untill 99MY with the thor engine. There is an diesel engine ecu multiplex signal output for the gearbox , but I don't know what the signals that it carries are. If you think that the engine temperature sensor is causing the problem then...

The Low line becm was a cost down version compared with the high line version and supported fewer features eg front fog lamps. A high line becm will work correctly in a low line becm vehicle but not the other way around.

. Correct, the engine's ecu coolant sensor signal is sent to the gearbox ecu from the engine ecu via the CAN-bus. This sensor has nothing to do with the temperature gauge, so a flickering temp gauge is not related to the gearbox problem, so don't waste your money on another temp gauge sensor...

I fitted a 2" lift kit to my 90 and scared myself a couple of times with the poor straight line stability (nearly had the vehicle drive off the motorway into a ditch). Without modified trailing arms, the castor angle changes with a lifting kit. I had to correct the castor angle by rotating the...

Make sure the becm has a "H" (for High line) written on the becm label (on top of the becm fusebox). The Low line becm does not support front fog lights.

Remove the connector from the back of the centre console switch pack and check that with the ignition on there is ~12v on the power feed which comes from the becm. The illumination also comes from the becm, but on a separate feed wire. Dry everything out as suggested by the other guys. Ref...

When you say you want to fit your own remote alarm to it, I assume that you want get the cdl system working again. If you actually want to get the alarm system working again then my advice would be to leave the alarm as it is now ie with the passive immobilization disabled (the immobilization...

The police spec setting allows the becm to flash the main beam lamps.
