Another big sigh.
Passed emissions today.
Even better than last year. Probably because it was tuned properly on the dyno.

HC ppm =23 ...................144

NOx ppm 86 ...................1014

Wanted to post contact info for my dyno tuner.

His name is Ed Senf EMS, Inc. and he lives here in metro Atlanta.
He is a Georgia Tech Engineering school graduate and has been tuning for 18+ years.
There was a story about him and dyno tuning in Grassroots Motorsports Magazine a while back.
The two main teams he tuned professionally this year won their respective championships.
Rum Bum Racing GS division of the Grand Am Series and
Fall Line Racing in Chicago.
Ed tunes other makes beside BMW.

Ed travels around the country so if you interested just send him an email and see what you can work out.
Please don't bug him with questions about your tune as I know he is to busy for that and he simply won't answer.

Updated some info on first page.

Took the guys at United BMW in Alpharetta GA for a ride.
Four men in the car and it still chirped the tire into second.
They all had big grins on their faces when they got out.

Hey Mark, did you ever get that MM stroker on the dyno? As you know, there are some who question the hp claims they make. It would be great to see a real world result.

thanks

It's amazing what you can find here - an absolute wealth of information even for guys like me that have no idea what they are doing. That was super educational as I think about refreshing or upgrading my motor. Thanks!
