Hello Everyone,

Im a new member based in Austin Tx. Im also new to wiki page editing so bear with me for a while. VEMs attracted me because it had integrated ignition control. I soon realized though that it was far more capable than any other system in a working mans price range that Ive ever seen.

Here is a short description of the project I have in mind.

The target is a 1988 Alfa Romeo Milano 3.0 v6. This is a Bosch L-jet overhead cam 2 valve per cylinder 60 degree alloy v6 with removeable (wet) cylinder sleeves. The combustion chamber shape is very good for a 2 valve design as are the ports. This engine has somewhat restricted intake design since its shared with its smaller 2.5l sibling so Im strongly considering a rework of the intake to go along with the VEMs installation. A big project for sure.

Some VEMs features Id like to include initially:

Q. A new software feature Id like to see is a Temperature based Rev Limiter . On motors with light flywheels this can protect the engine while cold. How feasible would this be to implement?

Q. What about VEMs and ITB ? Ive heard ITBs sometimes need multiple maps based on throttle position but have no experience with this. How do you accurately montitor MAP/MAT?

Q. I did a CVS checkout of the firmware and did a test build on a linux platform as an excercise. Looks like the compile worked ok (avr-gcc) but in the boot subdir make fails because ioinit.c is missing. Is CVS the wrong way to retrieve firmware source?

-Tom.
