    Yeah, if an OS upgrade is available is may be worth while to use it.

    It would remove the sec VE table and give you just one primary table that matches the stock one or if only a 2 bar table was...

    You need to wire in a separate IAT sensor or plug the MAF back in and just use it for the IAT sensor. You can not run this engine when it thinks the air temps are -38 degrees.

    Too much timing in the upper rpms if you ask me. I'd bet that it would make the same power on 25-27 degrees than it does at 28-30.

    If you have timing adders, remember to take those into account if...

    Yes.

    Look up the wideband through the EGR circuit on the web, this forum and youtube video's. It's one of the most common ways to log it other than the pro version or an analog input.

    Should be very straight forward. You are only going to change like 4-5 different tables.

    Injector flow rate vs KPA

    Min Injector pulse

    Offset vs volts vs vac

    Short pulse adder limit

    Tuner locking isn't available for everything. So without knowing what you are working with, it's tough to say if you can do it.

    And to be honest, locking the tune is kinda dumb if you ask me. What...

    It may be worth emailing support directly to ask them there as well.

    What's your parts list though?

    So far I can only tell you that you need to change the cylinder volume to match the 403 cubic inches and that you need to set the MAF fail high under the engine diag...

    Without some way for us or you to see the wideband data in the logs, it's not possible to see what the fueling in doing compared to what it's commanding.

    You never set the MAF dtc's to MIL on first error. Second error could be a cause for it not starting on the first try in some cases. It needs to display the fault...

    Try removing the non working channels. Then connect to the car, re-poll for supported parameters under the vehicle tab and try adding the channels back in. Start and log and see what happens.

    My point was that if nothing is available on that file, you are shit outta luck.

    There are other work arounds if you so choose.

    Why do you want it to have such extreme timing swing in drive?

    The load on the engine is going to tame it down a bunch.

    Older versions of the software moved it to a folder.
