Bump. How's this coming Andrew?

Oh hey! I've just been waiting for the engine mounts to arrive. I bought a new set of SS brake lines from Classic Tube, so I'll be installing those soon. I uncovered holes in the chassis behind where the gearbox crossmember mounts, so I've been trying to decide whether to fix those or replace the whole chassis because the rear crossmember needs attention as well. I guess I'll just take some pix and get some quotes from local welders.

Also, I was able to track down a second-hand rear bell housing piece off a Defender 2.8i from a shop in South Africa. It's looking like its NLA new from Land Rover. When I get it I'll take detailed photos and measurements of it along with the engine mounts. Maybe I can find someone local who can make CAD files I can share online. The same outfit also has a set of air intake ducts that go to the side wing, so I ordered a new left side outer wing with the intake hole. I already have a set of new door bottoms so I'll have it painted with those. Also, I looked into if my existing tachometer or a new VDO Vision tachometer would work with the BMW engine. I decided that those would not, so today I ordered a new Defender 2.8i tachometer (YAE100760) from Paddocks (their price was lower than britcar, but I don't know what the postage is yet). I guess I'll find out tomorrow if it's NLA. Hopefully not.

My new Defender 2.8i tachometer arrived today from the UK. It even says M52 on it.

I got gas pedal brackets for a BMW i3. I think they're gonna work out well!

Shaking my head in disbelief at the commitment necessary to see this through. It was hard enough with a "generic" Rover V8 rebuild. You just take it to a whole new level.

It's fun. The new left side wing just arrived from SP Landrovers. Callie had to inspect it. It seems to be good quality.

Is that the same as a Tdi fender?

I've decided to go a different direction with the gas pedal. I'm going to keep the original Defender gas pedal in the truck and simply replace the cable with a potentiometer. Once I get it mounted correctly I think it should work out very nicely. The potentiometer was used on later Z3's and also on the 1999 540i & 740i. BMW used this to adapt the regular cable-actuating gas pedal to drive-by-wire before they started replacing the pedal with the electronic version.

Thanks to everyone for your suggestions!

That's a great way to keep electronics compatible with your ECU but maintain the robustness of the stock pedal!

After a little more digging I discovered the Freelander uses the same Bosch potentiometer (Bosch part # 0281002291 & Land Rover part # SLD100061) so I'm getting one of those with the gas pedal. Hopefully that'll work out pretty good!

I noticed the potentiometer for a Porsche uses the same type of potentiometer as for BMW/Freelander but it's cable actuated so that gave me another idea. If the Freelander pedal doesn't work out then I could put a throttle pulley on the potentiometer so I could keep the Defender pedal as it is.

I still don't understand the aversion to the td5 pedal! Send me this freelancer pedal or the potentiometer and I'll compare their output to the td5 pedal for you. I have a hard time believing the output will be any different.

I don't know the output of the Freelander potentiometer, but I think you're right. Doesn't the Td5 pedal have 7 wires coming from it and 5 going to the computer? I think I am going to try the Puma TDCi pedal which has 6 wires. I was a little stubborn about not trying it before, but I found 4 variations of the pedal diagram for the LR4 that shows what the wires are and I compared that to the TDCi pedal so I know how to wire it now. So I'll try that and the Freelander pedal will be my backup option.

I found these specs here for the Freelander potentiometer.

One of the sensors has an output of 0.7V closed to 3.7V open and the other has an output of 0.35V closed to 1.85V open.

What I'm posting below is what the MS43 ECU is expecting from the accelerator pedal according to BMW. I haven't yet been able to find specific information for the accelerator pedal position sensor for either the Land Rover TD5 or TDCi. Do you think the ECU's in those Land Rovers are expecting the same? It's interesting that the voltages Land Rover lists for the MS43 (Freelander) don't exactly match what BMW shows even though they are using the same Bosch potentiometer, so if the TD5 or TDCi pedal provide a similar range then I figure one of those would probably be okay to use.

These both have one pot having half the value of the other. The td5 pedal has one pot that is the inverse of the other. At any point the sum of the two is the reference voltage. So different for sure.

Oh, interesting. So to be safe then I'll use the Freelander pedal. Since the Freelander with the 2.5 KV6 uses the MS43 ECU just like the BMW M54 then that must be why they use the same potentiometer.

Very cool!

Weld in or bolt? Doesn't look like much to them - should be straight forward to replicate if needed.
