No Kill switch as I will not be racing this thing anytime soon.

Just chasing issues and correcting them trying to get the car to a good base before continuing the modifying.

On the same car, related project. The car drives well. Still need to tune out some lean spots on cruise.

On to the good stuff.

What you see in the middle is a Tesla model S Media Control unit.

I was just doing a test fit to get an idea on what will need a saw put to it.

I have been in the middle of reading CanBus messages from MCU to other Tesla parts along with mapping out the file structure (it is a linux based OS).

Time will tell if this pans out. :)

Here we go..details in the video.

Idle is low. That is good and also bad.

1150cc/min injectors idling at 650 on E85. Not to bad.

Even cold start is at 650. Should be 1200-1400rpm cold start. Iacv is still shot.

Standalone is an AEMV1.

Not too bad. I like that Tesla screen concept you are working on. When are you going going to attach the Tesla batteries and electric drive motor to the mk3 Supra as I really would like to see someone make a electric mk3 Supra?

That will be another under taking.

The mcu is a beast to figure out but this is the hub intelligence of the car.

So for the Tesla conversion. Complicated but not impossible.

Someone is working on an electric Delorean project name: Teslorean
http://www.teslorean.com/
).

I will be using a couple parts from a tesla.

Electric power steering rack (already aquired).
Electric brake booster
Parts off the model S A/c box to integrate into MCU.

All this stuff talks over CanBus and specifically, the Tesla model S has lots of CanBus channels that all talk with one another over what they call, the gateway.

This will be a long term project except power steering. That is next in line.

What's involved in the power steering? You just have to figure out the canbus control for variable boost?

Is the brake booster just a vacuum pump system?

Just curious why you would be doing these conversions, if there are advantages, or just something neat to do?

The conversions are to free up the mechanical system (ie no more power steering pump spinning all the time) and unrelated, lose some weight.

The power steering under the OEM style is constantly getting fluid circulated through it. Regardless if you are turning or straight line.

The brake system for the Tesla is totally electric. No vacuum at all. Most new cars are hence why active braking works. :)

Add to that, with the correct programming, both steering and braking effort can be adjusted for a true progressive power steering and braking AND if I really want to. Can make self driving a possibility.

The funny thing is that the Tesla rack is really a land rover steering rack.

In the end, it is also a neat thing to do.

The hot rods guys call this a resto-mod.
Chip Foose lead the way in that department.

Old tech with new controls (motec m1 will be controlling it now that the motor is solid).

A/c, NAV w GPS, sat radio, digital control of windows and selection for steering and braking feel. :D

If you want some information on how many amps the Tesla Model S steering rack pulls I can give you some data.

I investigated both the Model S and 3 - 12V electrical systems.

Looks like you have some cool things in store for this Supra!

If they pan out, indeed!


Were you digging for some information on the parts (model S and 3)?

I know the Electric power steering is up to 60 Amps for the EPS. The real question, what canbus ID sets steering assist rates.

Might pick your brain if you have anything on the ibooster master brake.

No, I perform whole vehicle powernet investigations. (Primarily 12V & 48V systems)
Unfortunately I won't be able to help much on the canbus ID's, didn't look at that much.

I will send you a couple logs one of these days if you are interested.
Might help you size any fuses/relays/wiring ect... in the EPS system you are designing.

The iboosters are pretty cool units, nice gearing inside.
Teslorean might be a good source for information on scavenging all these Tesla parts.

I am a fluid type guy only reason i would get rid of it is for dry sump pump


simple wins race's and keeps more hair on your head instead of pulling ti all out lol


ps electronic brakes feel awful can't feel the road hell it's hard to feel a warpped rotor some times

Funny enough, this whole idea came from the teslorean build. I have been on both the Tesla and BMW boards (I can fill you in offline) scouring for CanBus info.

Are you keeping the speakers in the back once you get all the bugs fixed? I love riding with my targa out, but you don't have any targa holders and I'm not sure it'll fit behind your seats. Just curious as to what you are going to do. I take my top out and put my weezl wings in. I don't drive mine if there's chance of rain anyways since I'm on MT ET streets.

Well i dislike the feel of the wet noodle once i take the targa off.

With that said, when the time comes, i will have to source the interior trim that has the targa top mounts on it but that is low priority.

The car has been running fine on a steady E85 diet. I still have to tune some spots but it is almost there. I am not sure but I have this feeling that one of the injectors is not behaving correctly. if i swap them out, i am going back to ID's for sure!

the other high priority item is to replace the AEMv1 with something a lot more modern. Direction is the MoteC M1 series..

then fuel pump as i am eager to either go brushless or cam driven mecahnical fuel pump...

on a related note, I have the Tesla MCU on my bench and i have a power supply that i used for powering RC Car LiPo charging that can supply up to 1300 watts over 12vdc (and i can switch the voltage from 12v to 24v).

Electric brake is different than the tried and true master brake booster setup in that now a motor provides the assist and not vacuum. Other than that there is still a direct connection to the piston that influences the brake pressure in case there is a failure of the electrical system, you go back to full mechanical brake without assist (no different than when the engine stalls out).

Most high perf car uses that Bosch Ibooster for brake duties (all that auto brake stuff or collision avoidance has to be done electro-mechanically).
