View Full Version : Is there any way to run two DBW TBs on an E67 ECU?

Just as the topic states. V6 Application.

I understand the MAF can be eliminated and tuned on speed density without a CEL (that is correct, right?)

But I'd like to know if there is anyway to run two throttle bodies? I'm not sure how the wiring would work. It would essentially running twin stock TB's.

Thoughts?

Google around. There is a few people doing this with different approaches.

I have tried web searching. I've found nothing at relavent.

This is one thread on another forum that google found. :) There are other posts there about dual TB setups. One mechanical another running the motor in parallel IIRC. Be interesting to know whether the slave suffers from drift. :)

Wow thanks, not sure how I missed that. What were your search parameters?

IIRC "dual throttle body LS1" :)

Ahh, as I thought. I've come across this. It's just someone using the stock motor and sensor, and putting a couple of throttles side by side. Which might work out, but for this particular option, these throttle bodies will be about 3 feet apart...

I'm looking for trying to run two separate units.
