    while we are waiting...

    will the software eliminate the need for 02 sim and will the software be able to data-log an on-board wide-band 02 for a/f tuning. is it possible to replace the stock primary 02s with aftermarket wide-bands?

    For those wondering if this is worth doing I'll say yes. I'm very pleased with how my truck changed. It all around runs better. Cant wait for additional tuning!

    Was adjusting speedo added? Currently have a hand held and it doesn't do that. Just curious. Would like to change it at the ecu instead of the hypertech inline.

    @OVTune anyway to know what has changed between updates. Just checked and updated from version 1.49 to 1.52. Curious if and what changes were made.

    no idea. if it's not supported by this software, it would be sad to have to buy a hyper-tech programmer in addition to this software for that feature.

    I've been talking with Matt about the O2 Sim, and he's said that he can eliminate the 0420/0430 codes related to that. I'm tuned and looking to eliminate the need of the urd sim. He's working on an updated file for that.

    Can't find it at the moment, but I believe Matt said the speedo calibration can't be corrected by the tune as it's not directly controlled by the ECU.

    So by running long tubes they’ll be no need to run o2 sims as the software will eliminate the codes

    That's what I'm understanding. Not sure if the rear sensors will be able to be completely removed, or if they will still be required to be installed.

    My truck now has only 2 sensors because I eliminated 2 senosors when I installed the urd y-pipe. That eliminated the rear cats and rear sensors....
    I’m running shorty headers and high flow cats now

    thats what I thought on the speedo. I already had a hypertech which corrects the speedo but if yo plug any obdc into, the computer still reads the stock speed calibration so seems the ECU has something related to the speed. If it did would be cool but seems only the inline setup does it so far.

    Hey everyone

    Closer to the end of this month we will have a big update to our TRD SC calibrations including new updates for shift improvements and much more.

    We are still working on adding the last few ecus that are left. I believe it is only 3 N/A ECUs. And then we are all good to go.
    After that we will finally have more. Rafael will be taking over all handheld base communications so once we do go back online it will be a smooth process!
