hemi wireharness cut/splice ?

The last two new cars I've owned have been drive by wire. In the first case, I didn't know until the check engine light came on and I began to do some research. In both cases throttle response was excellent and the system responded well and immediately to my input.

The only downside is that in most cases you can't power brake a drive by wire setup. The computer sees both the brake and gas being applied and will close the throttle plate regardless of the fact that your foot is on the floor.

This is a safety devise, if the computer thinks that the gas pedal might be stuck and the driver is putting on the brake is shuts the throttle. Toyotas DID NOT have this feature until AFTER the throttle scare (which was probably 99.9% driver error).

There are pros and cons to both the factory ecu and MS3. If you can pick up the correct harness and computer for a couple of hundred bucks total, it would be well worth your time to try to figure out how to do it. MS3 is pretty cheap, but in the long run it is comparable in price to a Hot Wire harness and one of their reprogrammed units.

Best of luck,
