    It will be September before I can go again. I’d like to see what your truck gained, if any.
  2. Random thought thread

    Going to the track tonight?
  3. Random thought thread

    I’m still good for today.
  4. Try this, open in your graphs. LTFT + STFT vve.Table.xml
  5. Read post below. My phone is retarded That should get you going. 6310 is your fuel trim cell which will filter the Deceleration fuel cut off from the logs. 50090.156 is throttle position, filtering by position greater than 25%, less than a 5% movement over 200 millisecond, 50010.242 is Engine coolant greater than 170 to filter warmup fuel adders, and 50118.238 is your commanded eq ratio, filtering pe data. You will notice that you won’t get any data, your commanded eq ratio never goes higher than .987 so you will need to fix that. Your car never goes into closed loop.
  6. Garbage in=garbage out. Use filters, you don’t need transient fueling, dfco, or pe giving you false data.
  7. Yes you have to calculate coefficients every time you make a change. Make sure you are making changes to the correct map, manifold switch closed.
  8. I haven’t watched the video. What I’m telling you to do will fail it however. Your car will run terrible, expect it to. And make sure the channel units in the graph are the same unit, ie mg and mg or gram and gram. Vve will be in mg.

    Gotta get past me first sucka! I see reduced power mode in your future lol.
  10. I’m in class right now
  11. It’s going to run like absolute crap until you get it dialed in, that’s to be expected. If it only logged the “10” cell then you are missing a input in your channels. Bear in mind that ve tuning is very very time consuming and requires you to be able to interpret the data and predict trends. Filters in your graph will be your best friend or you will end up chasing your tail.
  12. Under engine diagnostics, airflow
  13. That just disabled your ltft’s. Nothing to do with speed density. Set maf fail hertz to 1, and set dtc p101, 102 and 103 to report error on first error with check engine light enabled. Reenable ltft and use stft+ltft as your math parameter.
  14. Engine diagnostic under airflow
  15. Yes, make a graph to copy your vve table after you adjust it to your predicted airflow. I would set it to around 1,000mg. Use the ltft+stft math to get your error percentages. On your logs add predicted engine torque and delivered engine torque.

    Anytime after 10am.

    Bring it by next Sunday.
  18. Random thought thread

    I’m not sure what direction I’m going with it yet. I’ve got a spare 6.0 or 5.3, 799 with tbss intake or 823 heads with a l92 intake, s475,s480,gt45, or a 7875 turbo. I do know I’m going to lower it 4/6, coilovers up front and big brakes with a hydroboost conversion.

    My best time. Ran almost the exact same time twice.
  20. Random thought thread

    It’s got a small cam and a tune now. I didn’t run it completely stock.
  21. Random thought thread

    Yeah I bought another one, I still have my white truck. Turnout for the race was pretty weak but I got to run a lot.
  22. Random thought thread

    Rcsb 4x4 4.8 truck and it ended up running a 10.90 at 67.27. First run was a 11.36 at 64.53.

    @tino truck racing at the hill. Bring your junk out and race my Sierra! (It’s pretty much stock and a 4.8 truck)
