Tuning a spare computer?

Does it make sense to get a spare Ecu to install and then tune / delete your truck? Anyone ever do this to a vehical? Not sure if it would hide everything from a dealer if/when you take it in for warranty work. or if this idea would work in general. Seems like you could return it completely back to stock.

I just had the ring and pinion replaced in my truck under warranty. Brought the truck in tuned and deleted, the dealer couldnt have cared less. Unless you melt a piston or burn up a transmission I cant see the warranty being voided.

much easier and cheaper to simply return it to stock before taking it to the dealer

It will not work, the ECU is programmed to the truck and multiple other computers as they all communicate together. You can not swap ECUs without reprogramming all the other modules to work together.. your truck will not start. No point in doing this any more.

thanks for clearing that up, figured with all the computers on the new trucks something wouldn’t line up. Probably just gonna delete and keep all stock parts.

VQ2Fast, would you mind sharing your delete/tune solution?

93notch, not meaning to hijack your thread. Solid question though.

I just run an ezlynk tuner with all the common hardware that goes along with a delete, nothing out of the ordinary. Im just waiting on ezlynk to release all the baseline parameters so I can write my own tune, im not a fan of the currant files offered by the techs.

Sounds like fraud to me.

Returning the computer to stock won't get rid of all the evidence that there was a tuner installed. There is software in the truck (no, I won't say where) that can detect when the engine makes more power than stock. When it sees this it sets a code that is stored away from the engine computer. If you can find this code you'll also find that you can't delete it. The dealers can find the code and if they do, they can deny a warranty claim that could be due to more power than stock.

I know about this because I was at Ford when it was developed. I worked with the people that created this software. I won't argue whether it exists or not, nor will I describe how it works. I really don't care if anyone believes me or not, I post this for the benefit of those that are concerned about keeping their warranty intact.

Sounds like it's in the transmission from your signature..............

Part of it is in the transmission and built in to the torque management. If you have the money and access to IDS its not hard to create a second ECU. You just have to have access to the as built data and you can link everything including all modules. I don't advocate doing this but I also don't see it as a problem. It's so cost prohibitive for most people that it would never become a widespread issue. Look up the cost for the ECU and the core charge.
