1 of 1 BMW 840CI M5 Engine Swap

[Garageaholic]

Full EWS delete brain.. meaning everything gets whipped out of the brain and literallty just left with engine functionality.. its crazy what the ecu controls and all its functions.. it will have error codes one example ( rear doors are open, and tht is because swapping into an e31 which is a coupe the brain automatically believes since its not closed shut there is a problem) so we get the entire ecu flashed and zero out every funtion that is not needed into the swap car to prevent any error code that can cause a limp mode or engine to not start. Its crazy now how these guys learned the flash game so well on swap builds for BMW. It has trully evolved since a couple years ago, and guys just get better and better with it. They made the impossible very easy now with what they have learned !! This will be the same as you s85 swap

Yup that’s what I was thinking! I thought I could give it a shot to try to reprogram it myself. What software do you use for these types of ecu downloads?

yes sir ! Will let you guys know how that one will be in the making. Hope to start soon on the build as of now getting a couple things together for my next e31 which will be shown soon in another forum. Next build will have another s62 put in her but this time will be bone stock to factory and will look just about original ! Will be CA legal to smog and donor s62 comes from a vehicle i found in a yard with 10k miles !

While I personally have no interest in an engine swap for my 8(but I hope you can change my mind), I think your work is brilliant. I know the "Purists" will look down their noses on these threads, but to take a vehicle of any sort, and finish it to your particular taste, and driving experience, is far more interesting to see than a stock vehicle, in my humble opinion. I am in the process of a back seat delete, and am looking forward to seeing your roll bar design. I wish I had not seen the E36 seats in your 8, since I prefer them to the stock seats, so now I am looking.

Keep up the great work, as threads like this will keep this forum alive.

It is deleted at the moment! Jsut no roll cage yet. I will share a phot tomro of the set up and how it looks! I personally love the way it looks, and beside who ever sits int he back seat?!? Lol

I have had fx child seats in the back and sometimes you take friends with you.
I would keep the rear seats.

[G8nightman]

You must have some small friends not alot of room back there LOL.

[Fatandre]

Í have had my bro back there and he is 194 cm
We are though rather fit here in Europe 😱😙

It’s good to have the seats just in case

I will post the progress. I am not planning to do anything that is not reversable. I have gotten side tracked into clearing out the "junk in Eva's trunk". The amp and telephone junk, the trap door, ski boot, first aid kit doors etc. I am going to put a speaker grill over the opening and center mount a sub in the trunk. Also going to dye the trunk carpets and panels black.

That is exactly why you take out the back seats, so you can't take your friends with you. Child seats?!?!?! You might as well take a goat in your car, far less mess and fewer foot prints on everything.

I am needing an update please. The roll bar/back seat delete is of interest to me.

[TheRecyclers]

Waiting on ym roll bar to be finsihed up. they are charing me $2000 for the custom bar will send photos over soon !

The swap is very clean, any car enthusiast can appreciate this.
It's good to see that there are more of these swaps being done.
When I did my swap there was very little to almost no information about performing this kind of surgery on an E31.

Great job Doctor

There is an S62 conversion running around here in Australia. I know a guy in Sydney who does these sort of conversions. They're time consuming but straight forward. Quality build results come from patience.
