HAHA this is stupid even if the devices could send data to the PCM they would have to pull the current tune as there could be 20 different versions of based on gears updates injectors or just a different program layout. Thats all for the same engine trans combo.

If it did that it would have to locate the address of what it wants to change know the offset if it is 8bit or 16bit. After it is changed correct the checksum then have the car in the run position with the engine off for 1-5min depending on PCM speed.

If that happens to fix it all you need to do is reburn the stock tune.

Burning out the injector drivers LOL I think people would know something is up when the car is smoking or the exhaust starts dripping gas from running a max fueling the whole time.
