AFR sniffer for easier jetting

Postby Areomyst » Sat May 06, 2017 9:58 pm

Recently I decided to take the plunge and build my own AFR sniffer for use on my dyno. I used a 14point7 Spartan II lambda controller with a Bosch 4.9 LSU wideband sensor. The sniffer is built from local hardware store supplies. I already had the vacuum pump, and the dyno software (Performance Trends's Dyno Datamite) was easy to setup and use with my home made AFR setup.

I built my sniffer based on the information found herehttp://daytona-twintec.com/download ... h_Note.pdf

So far it is working great! I will update this thread with more information soon.

I am trying to figure out weather or not I can upload photos from my phone. I will reply to this thread with photos when I can
.

At the moment everything is fairly unorganized as I was primarily getting everything up and running. I will tidy up soon.

I'm glad you know what you are doing. I am clueless with that stuff :D Hope it all works out.
