That upgrade will allow you to read your AFR down to 2.9 on the methanol scale. The sensor that comes with the standard system will go to 4.0.jim. they email me a price 2000.00 for the wb02 sensor up grade. thats has much has the big stuff. do i really need it?
a $1200 used classic fast box works just fine too ,lolIf you get the O-2 upgrade and the 24 injector upgrade it's about 4 k more but it does work!!!!!!
I still can't beleive you let out of that thing last nite!Spend the money and get the real deal!!! you will never look back!!!!
You cannot doubt data (and anyone can read it), no mater what! Reading plugs is ok but why rely on so many varyables when you get the facts instantly for the entire burnout, stage, launch, half track and top end???
One more thing... the time it will take you to get to optimum will be like the progress the world has had in the last 100 years vs the last 1000.....
