I've got one installed and ready to go, I'm wondering if anyone's tunned one on an NA before ? ( streetport and I/E mods, B&M fuel press regulator set to 40 spi)

 

You'll need to get on a dyno and use the air/fuel ratio sensor that they have. That is the only way to really know what you are doing is either good or bad. I have one but I'm using it on my '89 T2 with a hi-flo turbo and a few other goodies helping the engine come alive.

Wow, I'm glad to see I'm not the only guy with a HKS Super-AFR. They are easy to use and work great. The Apex units are as flexible and have way too many other gadgets built into them. The HKS unit works great. Just use a dyno to tune it.

 

yep, just looking for a basic base line to strat with. no problems.. it will run bypass till I set it. Oh and 4cyl is the setting for the S-afr when used in a roatary ? I thought I read that somewhere but couldn't find it again..
