    What?

    Where is the disconnect here?

    You are only using that other file to copy data from. You are not flashing someone else's file into yours.

    Kevin's file has the data to copy from.

    Which generation 6.0 are the injectors from?

    GEN 3 would be from a LQ4 pre 2007, those are only 24lb/hr. GEN 4 would be from a LY6/L96. The later GEN 4 injectors can flow up to 50lb/hr if they are...

    Fair warning here too, being that they are stock LQ4 6.0 just injectors they will support maybe half the horsepower that this new engine can give out.

    So you will have to get much larger ones if...

    Slow down a little bit and re-read my post.

    I'm trying to tell you that if you DO NOT have the stock file WITHOUT the 2 bar OS applied you have to do what I typed above.

    For sure that larger engine is going to need more base running airflow and likely more fuel too.

    Get a wideband in the exhaust or take your best guesstimate based on what your fuel trims are...

    If you can't return to stock then you will have to download a stock tune from the tune repository to get the information you need. Or take the file that Kevin gave you in post 2 for this data you...

    What did you do about the crank trigger differences?

    The LS3 is a GEN 4 engine.

    Is VATS turned off?

    Are you talking LY6/L96 MAP sensor and injectors settings because the LS3 uses square port...

    I said you have to flash back to the tune before the 2 bar OS. So I would hope you have been saving each tune under new names so that you can revert back to older tunes in case you do something...

    It will for sure throw your data logs off because the MAP values aren't accurate.

    I think you have the wrong MAP sensor settings for the MAP you are running.

    When you KOEO the MAP is reading 120kpa, it should only read around 100kpa depending on where you live. It also goes up...

    I think it's better if you don't post this stuff in 4-5 different threads when all you gotta do it start a thread and keep with it. More threads is normally just more dead ends.

    Paste the VE from your 1 bar tune into the 3 bar VE table. So copy from 15-105kpa over.

    I don't know why you applied the 3 bar speed density OS though. That is for someone wanting to run up to...

    Couldn't really tell ya because you don't have enough in the log to help you know what is going on.

    You do it the other way around. Because it runs on only the secondary VE table you need to make a chart in the scanner that matches that table. Log the data and with your results you paste that to...

    Why did you apply the 2 bar speed density OS to your truck??

    Are you going to run boost or not?

    This 2 bar OS gave you 3 new VE tables that come with zero data in them. So because these tables...

    If you think in lambda, everything is going to stay the same.

    If you pick a PE 1.180 with a stoich of 14.68 it's going to spit out the same commanded EQ ratio with the stoich at 9.78.

    Try some of things I said in your other thread, it's all stuff you will have to play with.

    The open loop EQ ratio should probably resemble something similar to the stock settings but maybe not as...

    Yeah, they are for sure overkill.

    FIC had 130 lb/hr injector that would have done 1,300hp on pump gas and about 1,000hp on true E85 fuel. Those would have been $600 less and they had 180lb/hrs...

    Finding a new computer may be a good option. Have it flashed with the VIN of the vehicle with a GM tool, then license that and go on your way.

    I'd be a tad hesitant at finding a stock file and...

    The L99 would have come with AFM/DoD and VVT. If L99, it's got a camshaft installed because the VVT has been turned off and same with all the DoD settings and trouble...

    I guess you could leave the stoich the same if you wish to keep it on the "gas scale", you'll still be tuning the airflow model the same way. With my widebands if it's setup for AFR, I don't bother...

    Did the dots line up when installed the camshaft?

    They did not add VVT on the 5.3 until 2010.
