    I am sure if we can prove the table over all the LS1 OS's they will look at implementing it. However since .cax files will still be supported with V8 there is probably no need.

    Just to let you guys know - this helped me with the 95#ers! But, they are still having issues with the cooling system on the car - trying to stuff a 100mm turbo in between the engine and radiator has proven to not work well... At least I was able to learn something and get it to idle right. Thanks again for all the help!

    Thanks for the update.
    Any ideas on how you will get around the cooling issues?

    Not really - the guy basically built a racecar and is trying to drive it on the street... The only thing I see that they could do would be to cut the core support and move the radiator out farther to make room and then switch the fans to pullers vice the pushers they currently are. I'm not involved with the build from that aspect (thankfully), so I told them to let me know when they get it right... It will drive around okay now, but as soon as you start hitting boost, even a little, the turbo heat shoots ECT up quickly... It has a blanket, which helped, but not enough... Just too tight putting all that in the front of an F-Body...

    I havent tested B9021 on a stock standard engine as yet. I know it was active in mine & a few of the cammed cars that have had this issue. But it could be something to do with a not fully stable idle triggering a transient condition. Hopefully the stock engined car coming in tomorrow will bring some insight into this.
    Cheers Mick
    Thanks, Mick! I'll try and get you a copy of my stock OS file this week and read up on what I need to do to make this work.

    Bringing this back to the top now that I am gettin back in the game.

    1) Please confirm that when I download the .cax file from Joe's March 27th post for OS 12212156 and place it into C:\Program Files\EFILive\V7.5\Calibrations, that I do or don't need to do a full flash for the change to take effect.

    2) Can we get the same transient min PW table done up for the OS in the attached stock file?

    I've got a cam'd car with SVO 30's and need to drop the minimums down to 1.08 to get rid of a rich decel issue. I'd also like to be able to try this out on my '99 as I'm 99% certain this is one of the major issues I coming across with it's rich decel as well.

    Hi Jeff.
    A full flash is only necessary when changes are made in the code section of the file, like when adding a COS. Since the changes made for min transient PW are in the calibration section of the file, a cal only flash will suffice.
    I will have a look at that OS & see if I can make something up for you.

    Jeff, What floor are you seeing for IBPW in the 99 Camaro?
    The 99 code is a lot different address wise to the later 2000+ so will take a bit of digging.

    I'm having the same problem with my turbo truck. I have the motron 60's and my ve table has always been screwed up from having the wrong injector settings. I would like to get the injector tables set up correctly so I can retune it the right way and not have the rich decel problem. Any help would be appreciated.
