    Weekend Cruiser= 2009 Pontiac G8 GT (Vararam, TSP LS3 N/A Stage 1, OBX, CTS-V converter, MagnaFlows w/ J-Pipes, 160 t-stat)
    Project Car= 1991 Chevrolet Camaro RS (LQ4 w/ Gen 4 Rods, LS3 heads, turbo...)

    this is the closest thing iv found to the issue im having. im also running the 30-0300 via serial adapter usb converter i know i need the pro link going to order it soon. i had no issues running the car on 91 it would register perfect for 14.7 converted to eq ratio. but now iv added the flex fuel kit my readings are way off in every direction commanded afr on 50% ethanol is 11.90 but the 30-0300 is reading 15.80-16.80 my eq seems ok when i base it off 14.7 afr but thats the wrong afr to begin with and no option to add a 11.90 afr in the transform settings. threw the manual i added the math but it gave me a 100 reading instead of 1.00 i did some messing to get it better but it causes the wideband to read incredibly rich on decel and fluctuates a lot. when ever i try to reset the peramiters in hp tuners the eq and afr both go to afr 14.7 so i have to mess with it a bunch and i feel like its messing with me a bit haha

    use lambda for WB and EQratio when on flex it will be much easier

    Correct thats what I'm trying to do but my wideband seems to default to 14.7 no matter what and thats what it reads even in lambda and eq ratio. Iv rattled my brain all day on this i just ordered the pro for my mpvi2 so I can run CAN or analog and hopefully that fixes my issues i actually have the 30-0310 so there is no Guage or anything to adjust the output so serial is probably not the best way to use it. I don't have another car atm so hopefully the tune is dialed in enough to handle the e85 thats in it. My stft and ltft stayed relatively good hit +10 -10 a few times today driving home but mostly stayed around single digits

    I have the 30-0334. I couldn't get the odb2 CAN BUS to work with any regularity. Even tho my vehicle is 2017. So I got the pro link, cut the odb2 plug off and wired the link analog. It works great that way. When you transform it, there is a 30.xx0 option that has good values.
