Dear Readers:

There are at least two reasons that I can think of, for getting inside the Digijet ROM:

1. We could remap the rom so as to tune engine performance to better match our individual local conditions (maybe a different torque curve for different geography?);

2. We could make modify and then make use of other non-vanagon ECU's (more about this later).

Now, there are products that allow you to get into the map rom for ECU's (www.3wad.com/ew/ is a link to such a product) and remap the rom as per your requirements.

Now, I may certainly be wrong, but I have been led to believe that the Digijet Fuel Injection System is an implementation of the Bosch L-Jetronic system, which was very widely used, even by domestic automakers.

So, my idea is to save money when we need to replace our ecu, by using any L-Jetronic ecu, and then remap the ROM to match our Vanagon engines specific map.

Can anybody comment on the feasability of my ideas? Am I correct regarding the digijet and L-Jetronic similarities? Has this ever been tried?
