EBP influence on tuning.

Just crossed my mind, I've had my exhaust back pressure sensor disconnected almost forever to keep the EBPV from closing. Is this having any effect on my tuning? Thanks.

Is the EBP sensor disconnected, or the EBPV solenoid disconnected?

The EBP sensor itself is disconnected, its easier to reach than the connector on the pedestal.

I think that the EBP can effect alot of things with the shifting, but with the connector completely disconnected the computer will ignore this sensor and revert to the MAP sensor to alter shifting/ firmness, etc.

I dont know if it will be enough to make a noticeable difference.

FWIW I have had my sensor remove from exhaust system (still hooked up electrically just no pressure reference) for quite awhile and had not notice any changes.

I appreciate the quick reply. I'd like Bill to confirm that there is no negative effect with the sensor disconnected. If I didnt have a 5" stack, the ebpv would still be operative.

See this thread here: http://forum.gopowerhungry.com/minot...706-boost.html

Light discussion about the EBP sensor, notice Bill doesn't say anything bad about having it disconnected. The PCM is able to use the MAP sensor in place, although not designed, because in an ideal world, EBP=Boost, although not so typically. So it is the next best thing when the computer can't "see" the EBP sensor. I've read of people trying to achieve a 1:1 ratio between drive pressure and boost. I'm guessing this would be for reaching peak efficiency. Feel free to correct me if I'm wrong.
