Thread: VE Table for 2Bar OS

  1. #1

    VE Table for 2Bar OS

    I am trying to find a VE table populated with at least numbers that will get me started on the SD tune, I have downloaded an HP Tuner Custom OS for a 2011 Camaro (12639279)
    I have previously worked with a Custom OS for a Gen 3 where I had a VE table to start with but not on the newer LS3 OS that comes with no values.

    I am unable to understand Bluecats VE progarm as well as the associated coefficients, One of the reasons in trying a Custom OS.
    Any help would be greatly appeciated

    I could give you mine, but it's not very accurate however it was converted using the EQ program from my stock 2010 tables, then it was smoothed to look like another guy's on here that I believe would me more accurate.. however do not trust it.. but it may run the car if it's a stock LS3.

    I don't currently use the VE tables as I am 100% MAF, but my car starts and runs fine in MAF mode... it's a 2010 LS3 manual trans stock, however now I have a whipple on it.

    Thanks, I am far from stock as you can see in my sig. Just trying to obtain one that may be close. I am going to tune SD and see if it will help with my transiet fueling problems. Can you tell me where to find "the other guys" ?

    Do this if you can, if not here use my VE table.

    Not sure if it will run your car, but definitely try tuning it. I DO NOT have anything higher than 95kpa and 2000rpm tested on this, so you need to tune it.

    It does start and drive my car under light load pretty good, pure SD (no MAF).

    Can you attach the actual tune (.hpt file) I am not able to do anything with the txt file. Thanks

    You can try mine. It's a stock LS3 08 Vette with intake, exhaust and long tubes. Nothing like what your motor will need, but it's a good starting point from scratch.

    Use your MAF and your wideband to build a SD table as a base. You can build an entire SD table without even being in SD.

    Solid advice. Yes you can, in fact, assuming your MAF is accurately modelled it is quite a quick task to build a useable VE table/coefficients.

    You don't even need your MAF to be accurate! It could be miles off.

    Agreed, yes, if you're using your wide band as part of the equation, but I find it easier to dial the MAF in as I'm going to be using it anyways, and then use the modelled air mass from the MAF to create a good model for the airflow in speed density. But, yes, you don't need an accurate MAF model, I just prefer to do that. Horses for courses I suppose. I certainly see the value in what you've said as it is using measured lambda straight up. In fact, it is probably the easier method.

    I used to use the MAF, but found that using lambda directly cuts the MAF error out of the equation. There's instances where using the MAF is easier though, for sure.

    When it comes to me and coefficients, "nothing is quite a quick task"
    For one, I do not understand how to build or find a PID in scanner that coincides with RPM vs MAP afr error or actual VE numbers to log with

    My current list of PID's for MAP vs AFR does not indicated the same data or orientation as in the Custom OS in HP Tuner Edit.

    I have coipied the VE table from "bbrooks98" above into my 2Bar OS but have yet tried to download. Even if it will start, trying to log info will be impossible without the correct tables in scanner. I know I must be missing something but I just don't know what.

    You have to define it all yourself. It isn't too hard.

    please share. I have GM VE plotted against my VE table, do you just copy the gmve table into hpt, then apply the lambda error to the tune?

    If I told you how to do it, you wouldn't learn anything!

    I'm going to have to ponder Dave's comments to figure out what he said.... Initail pondering has given me a headache.

    At any rate, I used the Bluecat tool to pull the data out of my tune file and built the VE table from those coefficients. After I had the table in the BC application, it was pretty simple to just copy/paste that data into the 2 bar VE table. I am NA, so I did not need to run MAP about 105, so I was able to increase resolution with the extra cells the 2 bar VE table had by interpolating between columns.

    After this rough' VE table was built, I used my wide band and VE / AFR error histo's to polish it up a bit.

    My VE table above 5000 rpm however is way off. I got a bit nervous trying to dial that area of the VE table in with PE disabled and all the SD multipliers set to 1.
    When arguing with an idiot, make sure he isn't doing the same thing....

    That link will get you the MAF based version... but the wideband version is slightly more complicated (and not outlined completely in that thread).
