From what I've seen, there are 2 ways to allow a wideband to control A/F ratio at WOT. 1) Purchase the TurboTweak 6.0 chip and powerlogger or 2) Go with the Gen 2 MAF translator and Extender chip.

My preference would be to use the GEN 2 translator with the 5.6 TurboTweak chip that I already own. Unfortunately the wide band tracking feature of the GEN 2 translator is not compatable with any other chips aside from the extender chip.

The overall cost would be a little lower with the GEN 2 translator because I already have an LS1 MAF, and it would allow me to sell the 2 stock MAF's that I own to recoup some of the investment. Also, I would need to purchase a laptop if I bought a powerlogger, but I do like the features of the powerlogger aside from enabling wideband control.

So for those that are using either system for wideband control of A/F; what are some of the advantages and disadvantages?.....and have you noticed any performance gains?
 
I'm running the Gen 2 and Extender Extreme chip. After getting the fuel parameters dialed in, the WB tracking is amazing as it will lock onto the programmed air/fuel reading during WOT. This made my transition to alky very quick and without much of a learning curve. I've picked up better than .4 and 3 mph since adding the Gen 2 and Alky Control kit, over running 110 race gas with the Commander chip on the same tune (timing 23/21, 22# boost). With the wideband set at 10.5 there still is more left the car at those settings. My experience with the Gen 2 has been wonderful, the car idles great and runs out like a top.
 
I'm going with option 1. Power logger gives me a window into the computer and I'm going to connect an A/F meter on the second WB lead from the LC-1. That and Eric is the man for chips.
 
I've read a little on Eric's speed density chip, but it sounds a little advanced for me.....more for the hardcore tuners. I want something simple and easy to use. If I do go with turbotweak, I'd upgrade to the 6.0 chip that features wideband control.



TT speed density and wide band tracking?

Switching from the extender to the tt on my blue limited = no more dying after a burnout and horrible idle quality.

A huge thanks to him for making my cars run what they do.
