Yep. You should definately give it a try. I highly reccomend it!
With a few mods to the code, this pcm can controll electric cooling fans, and datalog a wideband 02. The wideband cant be used to controll the fuel, but it can be displayed in the datastream right along with all the other data. I plan on added one for just cause sake..lol.
And to answer your question, I forgot. Yes, it datalogs at a much faster rate. Its pretty mutch instantly. I can turn the key on, and move the throttle and watch the needle on the tps guage move with my foot.
If your using tunerpro rt, just go over there and download the defination and datastream files and check them out. Make sure you get the tunerpro 5 versions. The two most common ones are 0E and 0D.
0D is for light duty vans and trucks with the 4L60E trans, and 0E is for heavyer duty trucks and vans with the 4L80E trans.
I am using a 454 bin, so mine is 0E, but they are both pretty much identical when displayed on tunerpro.
