Drive By Wire - Haltech How-To

"Here are total costs associated with this upgrade I just did.
- Bosch Throttle body $150 (Amazon)
- Billet throttle body flange $90
- Bosch wiring plug $12
- Pedal from a 4G eclipse $15 (Junkyard)
- Vibrant cast elbow $35 (local shop)
- Torque Solution clamp $85
- Fab work, piping & Labor $200
- Tuner adjusting the Haltech $125
: $712 no tax.

Now take into consideration that I did the fab work and welding myself, but I would charge someone $200 to do all this fab work if they brought me their car. Other people may charge less or more. These are straight costs for how I did it. You can save money by not using a cast elbow and boost clamp. Straight couplers are cheaper. Also if you tune the ecu yourself obviously no cost for a re tune


- Adding Cruise control
- Better idle
- Better cold start (especially w/E85)
- Traction control
- Throttle activated Exhaust bypass valve
- Eliminating Idle Motor, TPS and FIAV
- Safety. Nothing can jam the throttle open
- Better pedal travel/feel

Now someone mentioned that there is throttle delay when using Drive by Wire. I recently drove a friends car with Drive by Wire and I didn't notice any delay so I cannot confirm that it is an issue at this time. I will advise later on once I drive it around for a few miles.
Hope this was informative."

I was just reading into this a few days ago.

The throttle body from the Evo X, 4G69, 4B11, etc can be used as well. It's a 60mm piece that bolts to the stock manifold and would save most of the costs on the TB and fabrication (making this a $250ish proposition if you do your own work).

Is there any info on the wiring of the pedal and throttle body?

Looks like last update in Mar 2020, however I'd also be interested to know how it worked out.

A picture of the pedal installation would be nice ^^

I plan on mounting mine this weekend with rivnuts. If it works out I'll post some pictures

Anything happen to work out?

I ended up cutting the mounts off the pedal so it would sit flush on the firewall. I used one of the factory studs and a rivnut on the bottom. Worked out pretty good.

So cool

I really want to do this to my GVR4 with the Evo X TB and the 4g Eclipse gas pedal!
