Why not ditch the drive by wire altogether?? You have spent a lot on keeping in, I don't understand why, when I think you could do away with it altogether and have more control over the engine performance. The only benefits it would offer are for traction control, which obviously you are not going to have with this setup.

Where are you going to put the BMW ECU?

No, I've only the spent the cost of the electronic accelerator pedal. It doesn't change the cost of the ECU & tune. The M54 engine and ECU are designed for drive-by-wire operation. I would have to change a lot of parts on the engine including the throttle body to allow the utilization of a cable throttle. When I put the S54 into my E30 I was hesitant switching it to drive-by-wire so I originally bought an expensive cable throttle mechanism only to discover that it was very difficult to modulate because the S54's throttle bodies were not designed to be operated with a throttle cable. So I put the electronic throttle motor back on and installed an electronic pedal and everything was grand. :)

I'm going to put the BMW ECU in the upper right foot well where the old ECU was. I bought a wiring harness for a Z3 that should be plenty long to reach there.

I just called the Transmission Exchange Co. that's swapping out the input shaft on the R380 to get an update. They originally told me it would probably take about 2 hours to swap it out. Now they said according to their books that transmission isn't serviceable (okay...) and it's going to take 5 hours as long as everything goes as planned. So I'm looking at $560 now. I guess I should have tried doing it myself since I have the overhaul manual here and apparently they don't... Does that sound reasonable?

I was thinking of a M52tu throttle body, which is cable actuated. You would have to change the tune at the very least, if not use a M52tu DME, to use a throttle position sensor instead of a pedal sensor.
Personal preference here, but I would never put a sensor that I depended on for driving my Defender, in the floorboard. I'm sure you are aware, those pedal units aren't very robust even in a road going car, they get broken all the time by nothing more than a loose floor mat.

No, that's way too much work just to keep the cable throttle. Besides, the M52TU intake etc aren't even the same size. I'm not going to downgrade performance and technology. I'm not buying a new ECU and paying for a new tune either. I'm committed at this point. I've been thinking about how to mount the new pedal. Perhaps I can make sort of an L shaped bracket to mount it on that bolts on up above to the original pedal mounting points. I'll figure it out. :thumb:

You are going to get lost in the minutia of this project.

I applaud your efforts though. Good luck.

(Is it time to start taking side bets on if this gets finished?)

Hmm, I guess I won't ask for any more opinions and I'm going to do whatever I want. This is my project. I'll let you know when it's finished. :)

Do what you want, have fun, and be happy, but don't let us get you down! Ask away and take the responses with a grain of salt and you'll be fine.

Oh and show us some more pics of that dashing smile and it'll settle the natives.

Okay. I was a little irritated the transmission shop was charging me much more than their original quote, but it's all good now. They just called me and it is ready to be picked up! I think this calls for a toast! :)

IDK - the kid seems to have done his research, has experience with these Bimmer engines and has gotten a lot of big things done already. I'd wager he'll have his done way before my OM617 fires up (although that is not saying much).

Andrew - definitely don't discount what some people have said. There is certainly a solid KB on this board. I have had concrete plans with my build change after rethinking what others have said. But on the flip side - I have done some things that people have said "why??" to and been perfectly happy with the results. Keep it rolling and posting - this is one of the more interesting builds on here in a while.

Oh HAI!

Had to join up to watch this evolve since it migrated here from r3v. Please more pictures!

The world needs more 24v Rovers.

Hey welcome to the Defender Source! I agree!

My new air cleaner assembly arrived from John Deere today. It turns out it is exactly the same air cleaner used in the Defender 2.8i! John Deere part # RE58919. It comes with a new filter element too so that's nice.

Proof that we drive Tractors?
Indeed! lol

I don't know what's more expensive....
OEM John Deere parts or OEM Land Rover parts!!!!
they are both $$$$
Yeah, I surprised I could get it for less from John Deere than from a Donaldson distributor. I ordered it from www.greenfarmparts.com. It came out to $132.79 after a 2% off promo code plus free shipping.
