Lean Cruse How To?

[whenmunkysfly]

Any way we could get a write up on how a lean cruse setup would work and be setup. I'm really interested to find out how to get it setup because I make alot of roadtrips. thanks ether way.

1. get a good tune down- safe WOT AFR and Vf satisfied.

2. connect a WB to the MAFT pro

3. disconnect stock O2 sensor

4. enable part-throttle AFR tracking

5. set desired PT AFR tracking target (16:1? 17:1? you'll have to experiment).

be careful to have it drop out of PT AFR tracking fairly quickly...the last thing you want to do is run 17:1 in boost....

To be safe would it be a good idea to set your lean cruse on your aux. setting so you can switch to it when needed, and run normal AFR any other time, or does it not matter.

you need to unplug the stock O2 sensor or the ECU will work against the Pro.....
