    You have to be logging the exact data that the histogram uses, or you will get that error. At a minimum to use my histogram, you have to be logging ETC%, MAF in Hz, STFTs, and Fuel Trim Cell. Post...

    Just did some logging last night with LTFTs off. Came up with this histogram so you can directly paste right into your MAF table. Did multiply by % half and my trims are even closer...Thanks for...

    No, I'm definitely not tuning WOT with trims, just part throttle. I have a wideband for WOT tuning. The tune is pretty close, just wanted to clean up a few spots where the LTFTs were getting close...

    So you guys always start out tuning with just the short terms? I know I've heard of some doing it that way, just never tried. Guess I'm the type that sticks to what I've always done...I'll have to...

    Good point that I forgot to mention. So, to use the above Histogram, you have to be logging RPM, MAP, LTFT, and MAF Hz. Also, the above histogram filters out decel, and WOT trim cells, so they...

    This is one of the histograms I use to tune the LTFTs. I'd tune those first, get them close, then if you want, you can tune the STFTs. I don't usually go that far, if I can get my LTFTs within a...

    Yes, it is common to raise the PE enable MAP, but at the same time, the PE enable TPS is lowered...this basically allows PE to be enabled via MAP pressure and not TPS. Boosted applications are...

    Have you checked the commanded duty cycle for the cooling fan when A/C temps rise? I would expect to see it at 90%. The PCM will raise the duty cycle when A/C demands rise, based on system...

    The reason why you have to run lower timing in DoD is due to the excessive load on each cylinder...You now have four cylinders moving the car, not eight, so the load is essentially doubled. Add more...

    You need to use the "flow rate vs. volts" as a multiplier. Setup your IFR as if they were 50# injectors. Use the spreadsheet from EC Tune to get your curve correct. Then set all of the values in...

    The TBSS will allow WOT lockup...its locks up around 95 mph stock. You don't want to go locking up a high stall converter at WOT, unless it is designed to do so, otherwise you'll end up nuking your...

    You will end up with negative LTFTs...thats about it. Its easy to get the right IFR though, so I suggest setting it up correctly.

    You won't be able to directly cut and paste the tables, since they are on a different scale. You can subtract 400 from all of the LS2 table kPa scale, and it will get you close to the LS1 scaling,...

    My issue with the large offset between commanded and actual A/F is due to the relocation of my MAF for the ProCharger setup. It was previously on a bend, right near a neckdown section in the stock...

    The best way is probably going to be to go inside the transmission and make changes there. I have found that lots of trans builders install a spring that is too stiff on the 2nd accumulator. ...
