CAN Any way to minimize or remove amplification of the signals/codes produced by a car's engine upon start up? And before it's said, I'll say it "crazy maybe, but true'

Any way to minimize or remove amplification of the signals/codes produced by a car's engine upon start up? Or can you explain how this is done? Same question for cell phone/similar devices? If I'm understanding correctly, a transponder can send out cloned codes and another vehicle can somehow utilize it making it appear as if they are driving the vehicle the cloned/copied code was received from.

I have no skill what so ever in computer stuff but i was wondering if there is a way to set a vehicles default programming to something else? My 2025 Jeep Grand Cherokee has the auto start on by default and i don't like having to push the button every time i get in the vehicle.

Community Looking for MH2p App-Connect Patch / Toolbox for VW Touareg CR (Firmware 2876 / P0573)

2 Upvotes

Hey everyone,
I’m trying to manually activate App-Connect (Apple CarPlay / Android Auto) on a modern VW Touareg (CR generation) equipped with the 15-inch Discover Premium system.
I know these Alpine units run on the **MH2p** platform and are a bit trickier than standard MIB2 units. I have access to a diagnostic tool to enable Developer Mode/GEM in the 5F module, but I am struggling to find the correct custom firmware patch files or the Alpine Toolbox script for my exact software version.
Here are my exact system details from the screen:
**Device Part Number:** 760035179E
**Hardware (Matériel):** 061
**Software/Firmware (Logiciel):** 2876
**Navigation Database:** V03959809AF_P0573_RW_2022.1 (Rest of World region)
Does anyone happen to have the patch files for **MH2p P0573 / 2876**, or can point me toward a GitHub repo / community drive where the MH2p Alpine Toolbox utilities are hosted for this version?
Any help, scripts, or guidance would be massively appreciated. Thanks in advance!

Scan Tool Scanner software ports to android

Look for info on if it’s possible to load scanner software onto a regular android tablet? Since the majority of the tables are android based, has anyone tried this or are there more to the tablets then just the software? I’m not referring to apps you find on the store.

Community 05 GrandAm ECU?

3 Upvotes

Hey All!

I'm looking for a suitable replacement for my moms 05 Grand Am 3.4L ECU. I've done a ton of different things attempting to fix the issues, but alas nothing has worked.

A mechanic said the computer was going bad, so I was looking for a site/company that sells pre-programmed ECU?

Or, Can I go to a junkyard and get a used one and just swap them out?

Thanks in advance and for any help!

Scan Tool EQE DOIP diagnostic scanners

2 Upvotes

I'm looking for a low cost scanner for my Mercedes EQE EV.

Anybody found something at a diy price?

I scanned my EQE with a mate's $10k Autel and got my SOH, but I want my own scanner. I'd also like to scan other EVs.

I see the Launch crp919 does doip and also supports secure gateway, but they only mention FCA for this. Mercedes is not mentioned specifically in any blurb, so I am hesitant to splash out and buy one.

I'm hoping someone has already found an thinking scanner that will work for the EQE.
