    Can you post your stock read as well to compare them? I don't know what the stock shift points/pressures/etc are, so comparing will be helpful.

    I'll take a look through the modified file tonight.

    Pull and swap the crank reluctor. Unfortunately, that's going to be your best bet as there currently isn't (to my knowledge) a commercially available 24x -> 58x converter box.

    To echo 07GTS, do not write a different file to a different ECM. You MUST use the same ECM OS, do not try to Write Entire a different OS than the ECM currently has, it will brick and you will need to...

    Post your tune up so we can see what tables are available. I do see a note on the Supported Vehicles page that the Impala 3.5s are only supported from 07+, are you able to successfully read your...

    Yes. Worst case the Colorado isn't looking for the ISS signal the 70E's outputting and carries on. The 60E family is pretty simple, the only time you can get hung up is on 09+ transmissions where GM...

    Check the seller will actually use TDS and flash the ECM, not simply change the VIN. If they do the latter, you won't have the correct main and slave OS' in the ECM. Make sure it's the correct p/n...

    5.3 vs 6.0 is dead simple to adjust for. The different CAN/VPW protocol and comms is not, that's baked into the OS. So, pick the piece you can't adjust and start with that as the base (comms), then...

    Easiest thing to do will be to use a factory Colorado 5.3 V8 ECM and OS, as blindsquirrel said, you HAVE to use TDS/SPS to flash the entire ECM. HPT only flashes the main CPU, not the slave CPU...

    Use the 07 Burb TCM file, it'll work with 06 and 07 TBSS T42s, control the 80E, and play nice with both E40 and E67 ECM OSs. For 06 TBSS, it's the same TCM OS as the factory one so you can just...

    Reduce shift times by 50%.
    Reduce transmission TM by 50%.
    Increase line pressure by 5%.

    I used the repo file to come up with the 07 Suburban ECM + TCM OS pairing I mentioned in post 9 and yes, it's a unicorn, but very helpful for swap purposes!

    I'll be the broken record here, this is the reason why I've suggested trying to get your original 09 ECM working again. If it powers up and you can connect to it, you should be able to flash it back...

    The new 07 Vette ECM will brick if you try to flash it with HPTuners to a different OS not compatible with the ECM hardware.

    Can you Write entire the ECM? The T42 is pretty robust and usually takes any OS you throw at it.

    If you can get the 09 Express van ECM working, use the corresponding T42 OS so you have a matched...

    Ok what codes are showing up? Limp mode for the trans can be caused by a handful of things, including issues with the ECM side.

    If it's truly an issue with the TCM OS and 80E swap, you have 2...

    Glad to hear it!

    FWIW, you can go up to 22-24psi on the stock turbo, but it's not efficient up there and service life is severely diminished. I've been running ~20-21psi on my Sonic for over a...

    Post your tune up. Sounds like you're heading in the right direction, when you tune these you have to up driver demand. Also make sure you're not hitting one of the TQ limits.

    Go through and make sure the upshift and downshifts don't cross one another (e.g. 2->3 should always be higher than 3->2). The BlueCat tool helps generate that up front.

    Yep good advice, there are some rare exceptions where years cross over, but it's definitely oddball edge cases. Keep it simple and only look at your vehicle's year, going for an 80E swap I always...

    Ok that's an 04 P59 OS, go into the tune repo and download a 6L file for a 2004 Silverado. I did and it has OS 12585950 with an 80E.
