    How are you tackling that issue? Injector latency or air flow?

    Re: Anyone use DHP tuning software

    Im MAF tuning. I don't know what im doing but theres a spreadsheet/program I can upload a scan into along with the MAF table from my current .bin and it automatically adjusts the table. Its pretty slick and if your interested in taking a look at it let me know, its a pretty small program. You load your scan then the maf table then export the new maf table and put it in the bin. Im pretty close though. Im anywhere from 0 to -2.7 under any throttle but at cruise speeds and low rpm im seeing +3.9 max but mainly +3.12

    Nope I have used an auto adjust maf signal deal....you end up manually adjusting it at the end.


    Ok so when reading maf signals you'll need to increase the value where you have negative numbers on your soft and decrease where you have positive numbers. Don't worry too much about long term fuel.

    Re: Anyone use DHP tuning software

    From what ive been looking at the adjustments are fairly small as in +-0.2 does that seem normal. Im getting great numbers @ most throttle positions and wot @ 0 or close to. But low range rpm and cruising im seeing +3 and 4 at some intervals.

    Sooby I have good read but its related to a grand prix, the tuning is still somewhat the same across the board. Also youtube EFI tuning.
