    So here is the raw MAF Hz reading compared:
    97945

    Looking at this data it basically looks like the Rotofab doesn't do as much, although it still seems like it helps a little at higher rpms, so...

    Taking a quick look at a log I took before the cam and heads were put on and I am seeing 0.89 g at 4000 rpms, this is just with the same stock ported intake and TB and Rotofab minus the cam and...

    So barometric pressure is 14.1-14.2 psi here (for some reason barometer readings on the logs fluctuate and they fluctuate badly when you go WOT they tend to increase although not that much, no idea...

    Here is the airmass values I just grabbed from my logs in excel for comparison:

    97842

    228/236 Intake/Exhaust Duration
    111-ICL
    114-LSA
    0.635/0.635 Intake/Exhaust Lift

    Ported Stock LT1...

    I really hope we can end up using the C8 LT2 intake manifold, from what I am seeing it should help a lot. Apparently the LT1 intake manifold is extremely limited just due to how crowded the runners...

    I know there are some common rules of thumb for RPM shift points and peak power, but is there one for decreasing airmass? I would think the optimization would not just be at the inflection point/peak...

    Not to defer from the topic, but are we leaving good usable power out if I am shifting at 6800-7000 (7200 extreme rev limit cut off) with sub 236 duration cams? I have Johnson lifters and the PAC...

    So you are saying you have completely stock heads? I was thinking you had ported stock ones. TSP ported mine also and milled them 15 thousands. I also have a stock ported intake and stock ported TB....

    From my experiences with "Torque Management Advance", which it seems like its always a positive number that always pulls timing and not adds timing, is the most reliable indicator we have for...

    It seems like I wasn't really getting anywhere using my wideband to try to get VVE right, it would be rich one run the lean the next, I was only correcting multiply by half each time so I wasn't...

    We really need access to this as it would be very useful, but first we need a better understanding of the torque based system, which unfortunately most knowledge is kept a secret. I know you can...

    I've been trying so long to get consistent readings from my wideband and I am not getting anywhere trying different filters. The VVE or MAF tables just don't converge from feedback, the moment you...

    Does anyone know how much a bigger cam with more overlap effects the stock narrowband's feedback accuracy. I notice the same thing you are talking about with it swinging way too much in closed loop....
  15. How does everyone stabilize Idle Torque and/or Timing at Idle?

    I have been through over 100 logs trying to get VVE and MAF correlated to what my wideband tells me, although I doubt my wideband sometimes. I thought the issue was I just didn't have VVE good enough...

    My 2017 LT1 Camaro does the same thing always shows "Torque" for the throttle control source no matter what. I have a feeling we are missing a lot of the PIDs and a lot of them may be wrong or named...

    Mine has a lockout too, it is possible to put the block thing in backwards, I'm not sure if that will let it move more though.

    So I compared our airmasses from a log I just took. I have a TSP 228/236 111-ICL 114-LSA .635/.635in with PRC ported heads, ported stock intake, ported stock TB, and Rotofab CAI.
    So yes it looks...

    Here is one log where I have some higher rpm data. I also often find I will let it idle a little before I stop logging and I will think I will be lean then I let it idle and within a few min the...

    You can take a look at mine. I have a 228/236 114-111 .635/.635 cam with ported heads, TB, and intake in a Camaro LT1. VVE is still off since I still have a rough idle and it pulls way to much torque...

    What problems are you having with the AEM? I got the 30-334 X Series and maybe I am having the same problem because I am going in circles trying to tune VVE because I feel like my wideband is picking...

    I still have a problem that makes no sense to me.

    Here is my VVE histogram and I circled my idle region:

    So you can see I am almost right on and like you said this is what made my idle...

    So I apologize for doubting you. I kept thinking there is no way my VVE could be off that much since just looking at my wideband gage at idle I am seeing .97-1.03. I decided to put my wideband back...

    Long term trims are usually in the 3-5% range, sometimes a few cells get out in the 10% range, and then randomly sometimes you will see a short term trim go out to like 23% just for a second.
