using an Abaco meter & WB to tune Closed loop?

[87coupe50]

I just purchased an Abaco 97mm DBX and a Zeitronix ZT-2 WB. I got the Abaco mostly because of the size to match my boostmaster pipe (thinking that my current 75mm bullet might be a restriction) and the ZT-2 to monitor A/F, datalog RPM, TPS, MAF voltage and boost.

Then I got to thinking, maybe I could adjust the lower RPM MAF values (via the ABACO software) to fine tune closed loop operation (closely monitoring A/F ratio's) to increase MPG while just crusing around. I do have a supercharger with SCT tune. Would it work and not cause other potential issues? Or are there A/F settings in the tune (dependant on 02 sensor readings) for CL which would over ride any MAF changes? I'm thinking it's the later and "adaptive strategy(?)" would eventually make the changes pointless.

Figured I would ask the experts first before I start jacking things up.

Thanks,
Dan

If I'm understanding you right.... the adaptive strategy would push the AFR back toward stoich.

yeah, kinda hard for me to make an accurate statement or question when I dont know the "tuning" languange, yet.

Basically, you can change values of the Abaco meter internally; changing the voltages that it sends to the computer based on the air flow it is monitoring.

Been looking into the Quarterhourse and downloaded BE/EA, trying to learn what I can in order to tune my own car and not have to pay $300-500 for an SCT tune each time. Figure I can learn and play with the software now while I'm stuck in Iraq.

Don't worry, the terminology comes...
The QH is the route I would recommend.

The Abaco meters are very good, but tuning a car via the MAF voltage output is still less than ideal...
