Hello fuel-saver forum again,
I've finaly found the problem with the not working wideband efie, in fact its it who found me with its delectable burning plastic smell... So I guess you already know what's happening, according to the email you sent to people who bought wideband efies.

So from there, I guess I should contact bruce and arrange with him to get another efie...

Ahhh yes. We've fixed that problem. I'd send you a new one based on this post, but I don't know your real name and address.

Just contact support@fuelsaver-mpg.com. We'll get you a new one out right away.

All right, big thanks!!
