here is the deal with street tuning. hondata now has a autotune that allows you to set a targeted lambda, with a true wideband the system sets the actual lambda to or as close as possiable to the target it takes aprox. 2 hours and can be done at the dyno with the dyno set in dynotrack. witch allows a load be applied to the car. just food for thought. as far as base programs go dont trust them because every motor is different and requires a different tune. ie. no two cars will run the same exact fuel pres., cam timing, exaust?, etc. all witch play a roll in how the car respones to a tune.
