This guy is not someone I can watch much (no offense), but I accidently came across this:


Has anyone heard or tried anything like this? It sounds like Justin White will be featured on dude's channel later today...

Overwriting the tune every time you get out of and into the car? Having the thief crank the engine for minutes? I'm not a fan to be honest.

So if it's just a fuel cut-off tune, there's much easier ways to do it, though I will say this method is probably the most secure for the inconvenience. This method will only be accessible through your HPT account, so unless they've specifically targeted you and gone to great lengths to hack your account, get their hands on your device, then anything short of towing the vehicle is not going to work. It certainly wouldn't be used in a street takeover, and strictly stripped for parts as the ECU will be worthless locked up.

As far as fuel washout, maybe on the initial crank there will be a splash of fuel in the cylinders, we're talking measurable in milliliter's, it's not going to wash out the cylinders, not even close. After that initial squirt, there isn't enough vacuum draw against the injectors to syphon fuel out of the rail, and the mechanical pump won't build pressure if there isn't fuel being fed to it. That initial squirt at first crank is all that will be there. If there is spark present, it will get a little crap burn stumble out of that squirt and then you're just dry cranking. But if the fuel pump is feeding, then this is not the way to go. Maybe your car will still be there in the morning, but if they crank the shit out of it, before that battery dies you'll have enough fuel in your crank case that the cylinders are completely washed out. Provided you drop that oil before actually starting the car again, the car will likely turn over and run again, but there's going to be wear damage.

My method, given enough time or if I was followed and seen activating my kill switch, a thief could eventually find my kill switch. But I have also re-wired and relocated my OBDII port. So simply breaking my window and plugging in will yield disappointment. And have fun completely removing my dash trying to find the port, lol.

I think the OBDII relocation and a physical fuel cut-off switch makes things difficult enough for most theft events, most will give up and move on. Hell half or more will give up as soon as they reach down and find there isn't an OBDII port where there should be. Even if they had 10 minutes to spend finding the OBDII port while the alarm blares, then they would find the car doesn't turn over and have to find the kill switch. If they have my key and know where the kill switch is, I guess I'll be getting an insurance payout and a Shelby GT350

For people who park outside overnight, I do think this is a great alternative and very secure provided the fuel feed is actually off.

Aside from damaging the starter and battery, the engine would be fine turning a couple hundred RPM. It's still being fed oil. It's just kicking the shit out of the starter and battery. Provided it's not still being fed fuel as I talked about in my reply.

A no-crank scenario would be better, but that'll be a more elaborate and expensive anti-theft setup.

I didn't watch the video, but you have to load a tune each time? If so, it's the repeated loading of the tune that bothers me.

I've had an ECU brick before when tuning 14 years back. Hasn't stopped me from loading revisions on multiple platforms since, but I do have enough PTSD to not take the risk over and over for no gain.

Not really. $109 - https://www.mobilistics.com/nostart-...p-immobilizer/

With that you can immobilize the starter or fuel pump.

That's pretty slick, gonna have to do some digging on that and see if there's any reviews for it. Might have to add another layer of deterrent to my setup. I only use my fuel kill switch if I'm leaving the vehicle unattended for a prolonged period. If that relay is legit, that's a nice cheap layer of protection.

Search on this forum. It’s legit, many people use it.

I was thinking of the starter and the battery too, should've worded that more carefully The starter is not the most sturdy as it is, heh. But, to be honest, this would only happen if someone is actually trying to steal the car, ie pretty rarely.

I have mixed feelings about it. Pressing the button on the remote needs to be timed carefully after waking the car (say by opening the door), otherwise the start button remains inop (power to the starter is cut).

Now, while you can start the car anyway if this happens by going to the remote again, it seems the ECM/BCM tend to log various codes, which I'm not too happy about, especially since a few times this code was for invalid baro sensor data, which lit up the CEL, too. Never happens once I swap the stock relay back in, so I know it isn't the MAF sensor or anything else, the only culprit I can think of is the protection unit.

Plenty of reviews right here on this forum. I have it and love it.

Yeah read a bunch, looks like a good deal. It's a cheap layer of protection in my book. I ordered one and a hardwire transmitter. It's like buying guns. Excited to get it, praying it never has to save my ass.

I hid the original relay in the car, so it's always on hand in case something goes wrong with the Mobilistics relay.

Will probably do the same. With this added layer, I'm feeling pretty good that the car won't be going anywhere short of being towed. Even with a programmed key, it'll kill 'em for time.

I will say this, in his video he shows armature thieves take 2 minutes and 19 seconds to steal one of these cars.

I've seen videos of how long it takes a real pro to steal these cars. And I assure you it is less than 30 seconds.

How long do you think it will take these pros to setup a bypass or re-flash the system to remove the lock out? And it is a lock out that can cause damage to the engine. Its not a lock out if the engine cranks over.

My 2 cents.
