    Take a 20 minute log, see if you can get rpm into 4000-5000 range (just a few times), let's see what we get.
    New-CalcVE.pid
    Log_1.efi

    Attached are the PIDs and log. The tune is a MAF tune at least for now. I hit the default max frames, so it got cut off and I still have not ran the ext.AD wire to the WBO2. However I still think its of value, and I can get another tomorrow if needed. Thanks!

    Ok, I'm looking at your log...

    opcode,

    Good log

    ( sorry, in my previous reply I got crossed between you and Mean Green Z28 )

    remove these pids:
    - CALC.INJ1DC and CALC.INJ2DC, these are the wrong ones for E38 (you already are logging the right ones CALC.INJDCB1 and CALC.INJDCB2).
    - GM.MAF, this is static I don't know why (you already are logging the right one SAE.MAF).
    - GM.ENGLOAD.

    Get wideband going... and then take some logs where you briefly go to 4000-5000 rpm.

    Depending on whether SAE.LAMBDA works prooperly, we'll drop these pids:
    - E38.AFRATIO if SAE.LAMBDA works ok, or SAE.LAMBDA if it does not,
    - GM.ACCEP,
    - SAE.SHRTFT1,
    - SAE.SHRTFT2,
    - SAE.VSS,
    - SAE.ECT,
    this should bring the pid channel count down to 24.

    Yeah I did modify the pid file but didn't get to do much before I had travel for work. Sorry, will get some good runs in when I get back.

    Spoke to Bob at Injector Connection and got a pretty decent understanding on how to set up the tune with the new injectors. Leaving the stock IFR table as is and modify the iat modifier with a factor to match the different injectors (3.147 in this case), then change the small pulse and voltage tables etc to match.

    No worries, take your time.

    Can you post your injector data.

    Here's the before and after. Made the changes on the Stock tune.

    Basically, we looked at what the injectors flowed in the stock tune at 408kPa (29.653826 lb/hr) .. then looked at how much his injectors flowed at 408kPa (93.331 lb/hr) ... then divided to get the factor (3.147) ... then put that in the IAT vs. Fuel Flow table ... then modified the voltage/min pulse etc. to match the injectors as built.

    I'm on Malta time right now, haha so I'll probably reply at weird times

    Does your rail pressure measure 4-bar (58 psi)...?

    Ok, in your tune file I see that B4001 is sloped (goes as sqrt of pressure), this is correct for un-referenced FPR (I wanted to confirm that it matched realty).

    Ok, your scaling looks correct (I sanity checked the maths).

    No problem, I'm in So.Cal. but I usually stay up most of the night.

    Configured the my innovate MTX-L WB as below.
    • Stoich @ 14.13 (E10 Gas)
    • 10:1AFR@ 0v
    • 16.8:1AFR@ 5v


    github repo makes this a little easier for me, I hope thats ok.
    I made some changes to the posted calc_pids.txt for the above WBO2 config, and to read lambda from my new CALC.WBV
    I've also double the max frames to log in the scanner. However my laptop was not charged very much so I was only able to get a short log. please take a look an let me know if this is correct and useful.

    log2.efi

    p.s
    I think this config was getting ~40 frames/second, up from I think ~9

    not sure, I've never really checked recently. All he had me do was compare the values at 408kPa and add the multiplier and said that's all I need in addition to the other tables
