Question Anti theft map on UTEC

noob question...

Is it possible to have a map on the UTEC, that acts like the accessport Anti Theft B map?

Anti-Theft B: Anti-Theft mode, option B. Allow vehicle to start and idle (if warm). Vehicle dies instantly once RPMs increase over 1000. ALL Injectors.

For long term security I use both + viper starter kill.

Now delete this thread.

Don't delete just yet. Reason why I ask if it is possible to make "anti theft B map" because I have remote start. I want to be able to remote start the car, but just incase it does get stolen, I don't want it to disappear.

Sorry, I should have stated that in the first post.

hmmm. might be possible...but ive never tried it, and if you want to try it, its up to you...attempt at your own risk.

but just make a map where in the 0 column of the fuel map, you have 0's up to 1000rpms and then make the rest of the map the biggest negative fuel value. might be enough to kill the car. beats me. but keep in mind when you first start the car, it will stay above 1000 for a while.

Can't be done.

It really can be, but you won't find anyone who can do it. Does the UTEC anti-theft feature shut down the fuel pump or the injectors or spark? If it's the fuel pump, the alarm can easily redirect power to the pump that's been cut by the utec. It has a couple of outputs that can be used. If the injectors or plugs don't fire, then it's a lot harder to bypass.

Get a paging alarm like the viper 791 and lay your remote near your pistol like I do.

Another option is to put a hidden kill switch on the starter wire "upstream" from the remote start. Any decent remote start, installed properly, will shut down when the brake pedal is pressed, or the parking brake is released. With the kill switch between the ignition switch and the poinrt where the remote start triggered the starter, opening the connection, the thieves attempts to restart will be futile... hopefully. If the crook is good enough though, he'll still get your car.

What remote start do you have? And does anyone know the function of the UTEC antitheft feature? Hell, I'll run out and look at my fuel pressure right now to see if it can be done easilly.

Nope. It's not the fuel pump. Pressure stays up on that map. It's either injectors or coils that are shut down. Most remote starts have a "ground when activated" output. Thosecan be used to trigger 4 relays, which, when activated, would jump past the UTEC from the stock ECU to the stock wiring coming out of the UTEC to reconnect the coils or the injectors....

Or perhaps the UTEC shuts down the cam sensor, which, deactivated, wouldn't fire anything.

Anyone know what the UTEC uses to kill the engine? Anything it does can be bypassed, carefully, with relays. With that info, bring it to me. I'll wire it up.

Running a remote start anti-theft map would be feasable I guess. Run ECU in the 0 column for fuel and timing, then pull fuel, and retard the timing a rediculous amount across the rest of the board. What would be safer for the engine? Retarded or advanced? Either way I'd rather do it mechanicly.

Something i'm playing with. I have hooked up the UTEC's BCD switch to a 7 segment LED display so I can see what map is selected in the dark. A thought crossed my mind to wire the car's alarm alarm to another circuit which would select map 7 upon arming, then jump back to the umarmed map again upon disarming the alarm........kinda tricky but i'm trying to do it.

I believe the UTEC kills the injectors on map 7, the engine cranks but does not light up. You can also use this feature to prime a new turbo or even after an oil change, making sure the oil pressure is built up through turbo / engine before the car actually starts for real. IMHO.

If it's the injectors then there are 4 negative pulses coming out of the ECU that don't make it past the UTEC. 4 relays, with the normally open terminals connecting the corresponding ECU/UTEC wires to each other. Half of each relay coil conected to IGN and the other to the "ground when activated" output from the remote start would let the engine run normally during remote start.

When a crook jumps in to take the car, hit the brake pedal, the remote start function will shut down. The ground (and the ign + ) to each realy coil will be gone and the connection bypassing the UTEC will be gone. The security map will still be activated so even if the crook forces the ignition switch, it won't start.

At this point your big worry is to try not to get his blood on the hard to clean uphostry.

EDIT: If Gethin is right, then you can also use that feature to clear fuel out of the chambers if you just finished removing leaky/bad injectors. Set the security map, pull the plugs, and blast the raw fuel off your pistons.

I have the compustar FM alarm btw...

great insight guys... a little to technical for my noob brain.
I'll show my alarm guy this, and maybe he can figure something out.

Main reason why I wanted a setup like this because I wanted a kill switch like the one I had before [that kill switch saved my car last attempted theft]. But now, I have a two way pager alarm, with remote start. I just wanted the idea that if someone broke into her, the kill switch wouldn't let the car start. But, if I hit the remote start button on the pager, the car would start right up, and not rev pass 2K just incase some crackhead jumped in.

Maybe i'm just asking for to much... oh well.

I'd bet the remote start part of the alarm reads the tach and will turn off over a certain RPM already. I'm not familiar with the brand though. We only do Viper and Alpine alarms. Used to do Clifford, Excalibur and invisbeam (the one that rapped when the microwave sensor pick up motion... "Yo! I know you wanna look inside, but I suggest you step away from the ride!... and instead of "disarmd" it'd say "break it down" )

Back to the point, we only kept the most reliable lines. I hope that Compustar thing has the features you need. You might need to press anoter button first to bypass the UTEC, then press the start sequence button...
