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!
