EEC-IV Tip on Adaptive Control

Dale McPeters · 12-29-2005, 01:18 PM

In a street/strip car setup with an EEC-IV.
When trying to extend the range of adaptive control for upgrades such as bigger injectors etc. etc. the adaptive min & max control may need to be adjusted. Below is an example of an A9L stock setup under scalars >

Adaptive Control Maximum -- 0.621094 = Lambda
Adaptive Control Minimum --- 0.378906 = Lambda

To extend the range for adaptive the numbers would look kind of like the
examples below >

Adaptive Control Maximum -- 0.900000 = Lambda
Adaptive Control Minimum --- 0.100000 = Lambda

This helped in a case that I have been working on... YMMV.

Is this from a little dyno session?

Just curious, Dale, why was it necessary to do that? We all know about getting the maf curve as close as possible, etc, so the adaptive range is only needed if you don't get the curve real close.

Yep and some other related issues.

But what if your A/F is flat and steady but too lean or too rich?
