[info] VW Aircooled 1641CC engine

[mikedjames]

I am setting off on the aircooled EFI path choosing a MicroRusEFI ECU.


At the moment my 1975 VW T2 camper van runs a wasted spark crank fire ignition system with a 36-1 trigger wheel driving an EDIS-4 module.

The ECU is an STM32F103RB Blue Pill. It runs custom firmware that I wrote in C/C++

It relies on other software modules I wrote over the years.

In fact it began life as a rev counter add- on for a PLX Devices MFD..

I have rebuilt two engines so far, a VW aircooled for the camper van and a Yanmar single cylinder diesel.

I did start assembling a Bosch CIS mechanical FI for the engine but realised that there is increasing trouble getting spares. I had it all running on the bench but every time I went to fit it in the camper, some huge rust repair project would take over..

At the moment I am hoping to keep costs down, using ITBs off a Honda VFR800 , and manifolds intended for IDF carburettors.

Nice custom ECU!
