Computer for MFI motors?
« on: November 11, 2024, 03:44:17 »
Do some of you understand what this guy has created?  He seems to have designed and built automotive computers that he can adapt to Mechanical Fuel Injection motors like our in addition to carburetor motors.  Take a look at the 1960’s w111 at about 2 min.  Worth watching the whole short video. 

Those of you who understand tech, can explain to us (me) how he’s able get this performance.

He's converted the car from mechanical to fully electronic fuel injection and ignition. It's fairly common, here for example on a seventies Lancia Fulvia that was originally designed and built using carburetors and conventional ignition. A hobbyist engineer in North Carolina, building fuel rail, throttle bodies, air intake and using an off-the-shelf ECU that can be programmed to engine and injection/ignition system specifics:

Someone should develop a system for Pagodas, maybe someone already has.

Here is a company that makes 'generic' user programmable ECU's for conversions like this:

I've talked to a few companies that have developed similar systems for Pagodas but they like to talk about how hard it is and refuse to divulge any more details.

I sure love the minimalistic look of the post-conversion engine bays.

I’d never heard of an Arduino until yesterday when it popped up in the latest episode of Project Binky
https://www.youtube.com/watch?v=Fy2_CUBz40A . An arduino drives the dash.

(If you have the time and inclination, it’s a (now 10 year) tale of two blokes obsession with putting a 4wd Toyota Celica drivetrain into a classic mini)

Another one to look at: http://notronig.com/

I was thinking of getting my 190Sl there.

Thanks much !

I guess I’ve been under a rock and had never realized that our motors could be adapted to work with modern systems including fuel delivery. 

Appreciated

As the Kenyan gentleman explains, it's actually easier and less expensive to convert a mechanical fuel injected engine to the fully electronic one than an originally carburetted engine - because it's sort of already 'halfway there.' He seems to be saying he can put together a system fit for our W113 and send it to the customer anywhere in the world, estimating a cost of less than $2K for the setup. Worth a try someone?

If one’s w113 injection pump needed a full rebuild, and if one was thinking about 123 ignition, it might make sense to try this system instead. 

If I was in that situation, I might consider it.
