Apologies if this has been covered and I missed it in my search. It's been awhile since I used MPPS. The machine I used to use has long been decommissioned, and I can't find my install files from way back when. Can someone recommend a good (***SAFE***) place to download V13.02? Every site I'm finding either only has V12, or is totally suspect.

I have found a couple videos showing how to install V13 (and V13.02) on a Win10 or 11 machine, but they don't have links for the software.

Any help is greatly appreciated. I just had Josh Seyfert perform a major overhaul (all the stuff that happens at 190k miles; my third timing belt (etc.) change by Josh), and I'm excited to get my EGR delete bins running.

Thanks, all. Glad to still you're still here and cookin'!!!

Sent you an email & a PM with link to download v13.02 MPPS software from Dropbox. :wink:

If anyone else needs a copy of the MPPS v13.02 software, let me know, I can send you a link to download a compressed .rar file from DropBox. :wink:

Much appreciated. I downloaded it this morning, and I'm looking forward to getting my bin updated after work!

Thanks again.

Has anyone tried MPPS v21 or v18 yet to flash their KJ ECU?

Hi, could you please send me the link?

Thank you.

Sent you a link to the file in DropBox in an email and a PM.
It is a .rar file and must be extracted/decompressed to view.
To open a RAR file, you need to use an extraction tool like WinRAR (the native software), 7-Zip (a free alternative), or a similar third-party application to decompress and extract the contents. On Windows, you can typically right-click the file and select an extraction option, or double-click to open it in the program and then select which files to extract

Thank you very much, received and installed.

So I've got the Yeti 808 stock EGR/FCV delete installed with a physical EGR delete, but I keep getting the P0403 code. Not other codes are being registered. I've been searching the internet for about an hour, but I can't find anything on this issue (Yeti tune still showing Fault Code with physical delete). Anyone have any recommendations?

You should reach out to Yeti and ask him about this problem.
message him or email him.
