Using FiTech ECU as Anti-Theft Device - Questions

Hi All,
First off, this is not a post to rant about how my FiTech has made my car impossible to steal because it never starts! Mine is actually running very well...now. But there were MANY times along the path to having it run well when my, yes my way off CALs loaded to the ECU kept it from coming anywhere close to starting. And that got me thinking...well, it actually got me swearing, but after I finished swearing and it was running, I starting thinking that maybe I should create a CAL load specifically as an anti-theft measure.


For the FiTech (using GoEFI 600) there's one setting change that would keep the engine from starting, and a new CAL would not be required, just use the handheld to navigate to Go-EFI Initial Setup/Engine Setup/07-Tach or 2Wire+Coil. If set to "TACH" just change to "VRCOIL" or reverse those setting and presto, no starting that engine no matter how long you crank it. I've proven that works by mistake. The problem with that solution is the system still dumps fuel in the engine. The longer you try cranking it the more fuel that gets dumped, and that's not good at all. Do that too long and you'll have fouled plugs and it might be hard to start even when you correct the ignition issue...yep, proven that also.


I want to create a CAL, change it's name to "Security Locked" and have settings that disable both the ignition and the fuel. The ignition part is easy (read above), it's the fuel part for which I'm seeking assistance. I'm thinking if I set the Prime Fuel Mul to -100 and all the Crank Fuel settings to -70, that should keep any fuel from being delivered even if someone bypasses both my ignition and fuel pump kill switches. Anything else to change? Or is there one setting that would ensure no fuel would be delivered if someone is able to crank the engine?


To use this Security CAL I would first write the current CAL from ECU to the handheld to make sure all the learned data would be saved; then write the Security CAL to the ECU. When I want to use the car, I would just write the "good" CAL back to the ECU. If I forgot to load the good CAL it would be evident, but also, I would not have been causing any harm because no fuel would get dumped into the manifold. You might be thinking two kill switches would be enough, but I live in Albuquerque, NM...the auto theft capital of America! I want to make it so painful that even if the car was towed, and they found both switches, it still would not start...and there would be nothing physical for them to find to fix. This isn't a CAL I would use very often, but if I was leaving the car in a public place for a long time, such as for a show, or parking at a hotel when taking trips, I would use it as extra security.


And for anyone that came to this thread because their FiTech is serving as a non-intended, swear inducing security device...good luck getting it running!


Cheers!
Rick

Good idea, maybe easier to change something like cylinder count, or cid to something so far off it won't run, but it will draw attention as it almost does.

Re: Using FiTech ECU as Anti-Theft Device - Questions

I have been having the same thoughts in the back of my mind, I was thinking about setting the redline as low as it will go, but always forget to see what is. IF it can be set to zero, that would be a no start situation.

But regardless, if they want it, there are no amount of security measures that will trump a determined thief. Sometimes itís best to insure for replacement value and hope for the best.

Re: Using FiTech ECU as Anti-Theft Device - Questions

A small FiTech sticker in the corner of a window might also work.

I worry more about asshats in parking lots in big trucks swinging their doors out hard and dinging my body panels than anyone jacking my sled. I don't keep the handheld in the car that much, and although a good idea, I'd forget to do what you are talking about anyway.

I agree with John. If they really want it and know how to take it, they are going to take it.

Re: Using FiTech ECU as Anti-Theft Device - Questions

If they are going to steal it, they will have a tow truck. They are not gonna try to start it. Unlock the door with a slim jim (ridiculously easy on our cars), throw it in neutral, roll it around the corner where tow truck awaits. I witnessed this from my friends video footage when they stole his Charger, car was gone in less than 3 minutes.

Exactly. In another life as a young welder, I fixed many a repo truck.

Such a simple setup, regular looking pickup, nothing to see here kind of thing.

In the bed was a hydraulic extendable arm with hooks on it. The whole thing was mounted on a large swivel.

He gave a demo to us at the shop first time he came in, back up to the rear of the car in question while extending the arm, hook the car, and drive off while retracting the arm.

IIRC, there were about 5-6 buttons on the remote in the cab. I'm talking a huge remote, like one off an industrial 100 ton crane, but specifically made for the tow rig. It was awesome.

Whole thing took about 10 seconds.

Well those are depressing stories...no wonder so many folks trailer their rides! So for those that love to drive their cars on long trips...I guess the answer is to spend the night curled up in the back seat with Ms. Smith and Ms. Wesson!

Re: Using FiTech ECU as Anti-Theft Device - Questions

Actually, the sticker idea is great! "Warning: This car is protected by FiTech EFI; don't even try to start it!" Could serve dual purposes...provides a laugh for those in the know...and...if a thief does try to steal it and it doesn't start...and they come back and sue your ass for mental anguish (this is America after all!); you can explain you had posted a warning!

Re: Using FiTech ECU as Anti-Theft Device - Questions

The previous owner of my 67 Chevelle (350 ZZ4 crate engine) had a Fi-Tech professionally installed and it has been problem free for the last two years. When I took it on the initial test drive it wouldn't start and we quickly discovered one of the fuse holders near the Fi-Tech unit wasn't latching onto the fuse tightly enough. A simple fix. This gives me an idea for this thread... remove the fuse. Then when the key is turned on the fuel pump doesn't even run. Yeah I know it could be towed away anyway.

Most thefts are via roll back or tow truck. If they want it bad enough they are going to get it no matter what you do so just ensure you have it insured right.

That is the million dollar statement there. There are usually lots of restrictions and limitations on classic car policies. One a lot of people miss is if you are in a state that offers 'special' plates and those plates have restrictions all the insurance company has to say in their policy is that the car has to be legally operated and registered. Lets say you state has classic plates that are only good for weekends and something happens on a weekday? Insurance is off the hook because the car wasn't being operated legally based on the type of registration.



My state the classic plates (which I don't have) don't really mean much so the insurance company doesn't require them. Some states some insurance companies require the classic plates so you can really be limited to how and when you use the car.

Pull the ECU fuse and the fuel pump relay.
