did this air-fuel tuner ever catch on ?

looks like a neat economical SAFC alternative
anybody know anything about them in use ? thanks

0-5v AFM or MAP, is fine for what I want it for.
Gonna look into sourcing a pre-assembled unit
also ame accross this laptop adjusted one http://www.14point7.com/UAFC.php

They dont really work well on a map, as with an afm, they are sort of 3d tuning, wheras map they are only 2dquest wrote:0-5v AFM or MAP, is fine for what I want it for.

Basically a map reading 2 psi has the same output at 2000rpm and 5000rpm, wheras an AFM will read more voltage, as the voltage increases with airflow. The main drawback on these voltage benders is as you lean out the mixtures, the ignition timing is increased, so you usually get preignition before you get the mixtures you would like.
hmmmmm.... but a MAP wouldn't be able to fuel a motor properly if that were a problem, won't it ?Basically a map reading 2 psi has the same output at 2000rpm and 5000rpm, wheras an AFM will read more voltage, as the voltage increases with airflow.
Aren't cells adjustable for specific RPMs ?
A SAFC II works excelent on both MAP and AFM... trying to grasp why this particular gadget wouldn't

yep, understanding what the device is actually doing, is the key to amazing results.simply retard teh base timing 3 deg, and you can run almost optimal fuel and ignition for a highflow turbo up to around 220rwkw
DSMs monitor knock and ignition timing via cheap dataloggers. Big part of why they're so quick, even as heavy as they are.
