    Can someone check out my base file?

    Just wanted to have everything looked over to make sure I have the correct data for the injectors, map sensor, etc. Any additional help would be greatly appreciated.

    Looks like you cut the IFR in half then only added 50% to the flow rate multipler x volts table..

    Put both of the flow rate mult tables back to 1, then double the stoich value across the board, so 18.something if you're using E85

    Enable fuel trims. They can at least do some adjusting for you.

    Why is the wideband showing an absolutely flat 12.92? There's no way it's that stable

    It wasn't connected at the time. I saw that yesterday when I was looking at the map, the injector data was done by the previous tuner, not sure how it ran so well when it was na now haha thanks for the response!

    Yeah they must have messed the MAF or VE table up to make it work. People have done worse..

    Get fuel trims turned on and the wideband working and then you'll have a much better idea what's going on. Kind of flying blind without those.

    I think I may just start from scratch instead of trying to modify what was on there. Got the wideband working right after that log, its within .1 of the gauge. Thanks again for the help.

    Yeah that's probably easier

    After going to ID injectors big chunks of my VE table ended up surprisingly close to stock, so it should be fine to start from scratch.

    Did you go SD or still using a maf?

    I've done both, still playing around with it. I'm trying to keep the MAF because my fuel trims fluctuate a whole lot less from cold mornings to hot afternoon traffic when I'm using it, but I've had trouble getting the signal to be smooth enough to maintain steady AFR's. I added a honeycomb to help straighten out the air and that helped but it still bounces around a lot and the AFR's jump around with it

    I'm trying a new MAF this weekend so we'll see how it goes
