I bought the Mefi Burn software and in order to get the most accurate fine tune, I need to log O2 mixtures.

Where can I buy a set of spacers/O2 bung for my EMI Thunder setup ?

Call emi and talk to chris,,send the riserd to them and they will weld the bung's in..then polish them back up..

ill do that today....thx

all I can say it lots of luck getting 02's to live....

Mine have been working for four years. Installation error?

Jeff

only need em long enough to tune it one time.

My bungs are being welded in the Stainless Marine risers this week. I guess we are going down the same road. My impression is lot's of people have had success with doing this.

I have the aluminum risers. didnt get a chance to call em today, but will tomorrow.

Ive got my tune pretty close, but the time it will take me to learn everything, I could make 20x what it will cost someone to build me a MAP once I have all the data.

3 plus years on mine and still working great.

depends on exhaust, even in factory bung location water kills them quick..so no not install error...
