    Ah kk, obviously wasnt sure but thanks for the clarification!

    Yeah, I looked again and wasnt able to find those unfortunately - guessing thats something id need to ask support to look into or .. ?

    And ive read a tiny amount on the HPFP but i was under the impression a stage tune 2 (so like low 20 peak, high teens carry over) was obtainable if the current FP is still in good condition?

    Seems like LPFP duty was too low, try this

    also when you make logs you need to do a 3rd gear 2-7 that would be much better than what youre doing

    And that was evident just in the tune or you have an idea as to what the typical pressures are and mine are just low?

    Ill upload the new tune in the morning and take her for a drive. Most pulls are done in 3rd, but ill try and get a little more rev range out of them!

    As an FYI Ive gone and ordered a new cam follower that ill install this upcoming week just to be on the safe side - the HPFP upgrades kits are definitely more money than i thought theyd be hah

    As far as I can see from the logs and file the requested low pressure system is around .8bar short of what it should be

    Hey, so just got back from a drive with the tune you did last night - can definitely see more fuel! I also noticed that after logging a different IAT that theres a good degree of separation between it and ambient when you start getting into the upper rpm band, perhaps thats the correct one to be using?

    everything looks much better! I added a little bit of LPFP DC% as well as upped the rail pressure request slightly to get some more fuel into her

    timing was a bit too retarded at peak so i scaled the axis a bit higher, this should give us some positive timing values on spool up and added a tiny bit of fuel earlier on in the RPM range

    load was tapering off at the end of the pull pretty hard so i added a little bit of WGDC to the last column of maximum I-Term

    looking forward to seeing logs from this one it should go pretty good haha

    Have to say, its sincerely impressive how well you know these cars - I was making changes here and there for a month and youve done far more in a day lol. Honestly cant thank you enough

    Car seemed to have less initial lag and felt strong in the mid, upper is hard to tell as the roads around here are very windy and im more focused on that unfortunately

    haha thanks man, I Try. Just trying to learn and expand my knowledge like the rest of us

    still have that lean spot.... if my next attempt doesnt fix it i recommend looking at a fuel filter or maybe we lower the boost a tad

    i decided to ditch trying to maintain the 4.5Bar request from the LPFP and went ahead and put the duty values back to stock but requesting 5.25 bar now
