DBW vs cable throttle body
 

Hello all,

Since my turbo BP needs a rebuild again im thinking about going LS1 V8. Found a nice kit wich sells a complete kit including gearbox and ECU and wiring loom. But they sell both cable driven throttle bodie and Drive by wire throttle bodies engines.

I believe the cable driven one is found in a Camaro wich has about 315hp and the DBW is from the corvette and has about 350hp? Any downsides going DBW. Obviously need a corvette pedal and wiring. Also cruisecontrol is easy to wire up from what i found so far.

What is your preferred engine?

greetings,
Vincent

The GM DBW OEM setup gets cruise control commands from the BCM which is not included with your kit. Trying to add a BCM adds all kinds of problems with anti theft systems, etc. However, there is an aftermarket substitute. I needed one to activate the shift paddles for my 6L50 transmission. Got the ABS and cruise control as a side benefit. Company is first rate and I highly recommend them.

I know this is an old post but there is always the option of using the stock Miata cruise control system. Just need to attach a second throttle cable to the DBC throttle body. Also need to figure out a speed input if you are not using the factory speedometer. Stock instrument cluster uses a reed switch to send a 4 pulse/revolution signal to the Cruise Control Module.

I know you said you want to go cable throttle but, especially if you are going to install an aggresive cam, you should consider DBW. Its a lot better to tune on a cam than a cable throttle with ISC. I used to be a DBW hater, but after getting my hands into my first DBW tune, I decided to convert my 99 silverado to DBW just so much easier, and flat out better unless you are on a mild cam or stock cam.
