turbotweak had the first beta chips of the 6.0 wideband chips that worked without modding the ecm (MEr needed modding for inputs) and didnt need powerlogger
it allowed input of a wideband signal through the IAT using a simple adapter module he had made up.
with that you were able to run WOT and PE under closed loop with wideband correction , and still kept open loop idle , closed loop cruise and part throttle under the maf/02 sensor control
the chip allowed you to set the A/F target in 1st-2nd gear and 3rd-4th gear and could correct up to 20% , it also had lockup control and timing control +/- 10*
as for working with alky it made things easier
i ran that chip and logged old school ...directscan
today there is the Turbotweak 6.1 and Sd chips that require the powerlogger
or the bailey products ..
gen 2 translator or maft pro can do wideband control available at fullthrottlespeed.com or turbotweak.com ..theres a forum at
www.fullthrottletech.com and eric(turbotweak) has a forum if you need more details than the product description.
you dont need a powerlogger with the bailey stuff but logging makes tuning so much easier
