Re: Universal Patcher
Another advantage to having the PCM drive the fuel pump is if the car stalls it'll cut the pump. That is a great safety feature if there is an accident where a fuel hose may be broken and potentially a fire. I learnt that from motorsport scrutineering but the logic works anywhere.

Re: Universal Patcher
I never even considered that. Thanks for the info. I should be up and running in the next month or so. I need to pick a cam. L96 or LS2??? I may add boost later on, not sure. The L96 shares the same specs as the LQ9 in the in the article but is a single bot cam.antus wrote: ↑Mon Jun 09, 2025 10:06 am Another advantage to having the PCM drive the fuel pump is if the car stalls it'll cut the pump.

Re: Universal Patcher
Personally, I'd put it in bone stock and work out any swap related issues/bugs without also having to wonder if the cam/tune is contributing. Then consider doing cam/boost/etc once there's some miles on the swap with everything working as expected in stock form.
Re: Universal Patcher
Hi zach4200. Thanks for your reply. I plan on running it on the stand, first with the stock cam, then the upgraded cam. I plan on putting it in a Mustang, I know it will fit, butt tight. I use to own a 95 5.0L when it was new, was a fun car to drive in my 20's. Had it 10yrs. Ya I'm old as dirt LOL. I'm actively searching for a donor. They pop up from time to time. Have to be fast. I missed a nice 1 a couple months ago. Would of been perfect. Was mint, but the engine was dead. Basically I'm looking for a 94 and up, mint or VG condition mustang with a blown motor or tranny.
I want to get everything worked out on the stand. At least a good idle. Once it's in a car everything will be tight and would have to probably partially pull the engine to replace the cam.
Thanks again.

Re: Universal Patcher
Hi again guys. I have been trying to create a patch using the same bin, in Universal Patcher. The original and modified GM E38 12614088 bins. Gives errors. I finally noticed it loads a P01/P59 configuration file to create the patch. I'm guessing the E38 is not supported to create patches??? Does anyone know for sure??? Thanks for looking.

Re: Universal Patcher
It is supported. Looking at the xml files in the repo here https://github.com/joukoy/UniversalPatc ... er/Patches
There is a e38 vats patch v2 xml file. It's just pattern matching, if you are trying to make a new one you should base it on that to see how it works. I am not sure but I suspect universal patcher is looking for patterns for all platforms on all platforms which is why you see it mention the P01/P59 files. But it should try all of them. I think its looking for CompatibleOS where * is a wildcard, and if it finds it, then it replaces data over the top, the skips the *. So that patch is written in such a way that the replacement code will run, do whats needed, and not crash.

Re: Universal Patcher
Hi Antus, thanks for your reply. I guess I should of explained what I'm trying to do. I want to create a Patch to disable the DTC's for a standalone engine, using the list I came up with. This is what I have tried. The 1st bin I'm using is my original bin with the Vats delete patched to it. The 2nd bin is my original bin with Vats delete, and I have disabled the DTC's from my list.
I have looked for some way to choose the correct configuration file but it eludes me. It make me think Universal Patcher does not support creating patches with anything but P01/P59???? I am thinking the E38 Vats delete patch in Universal Patcher was created manually, but I really have no idea.
Universal Patcher is a good program, I just wish it was better documented, or had its own forum.
Any help is greatly appreciated. Thank for looking and have a great day!!!

Re: Universal Patcher
That really isn't a patch required type thing. You open the tuner portion of the software to see the list of DTC's and other defined maps to edit and manually disable what ones you want to get rid of.
Re: Universal Patcher
Hi veee8. Thanks for your reply. I know it's not needed, but it would be nice. It should be possible I thought. It says it creates a patch but I can't find it and no option to save. Thanks again. The attachment is using the patcher, when I tried in the tuner, is when I noticed the P01/P59 configuration.
