a well known tuner help me set up my tune here in el paso (around 4k) and the car runs perfect. a few weeks ago i trailered the car to houston to run at hrp. i took it cruising around for a day to get used to the elevation change but it had trouble idleing when i would come to a stop. i had a chance to look at the wb and it would go rich. the car ran fine running part and wot. any ideas?

 

it was dipping into the 11s until it found the idle at 800. the file is on my laptop at work so ill post it tomorrow.

 

It probably just needs to relearn Idle Trims.

It should do a BARO update along with Trims in the first 50 miles.

Somewhat of a unique problem. Trailering it down to lower elevations, it probably never did a BARO update till you restarted and met the min RPMS to initiate a relearn.

Hope that makes sense. It 'should' adjust itself in short time.

here is a log. notice i have to bump the accelerator when she goes rich.

 

The baro sensor probably isnt adjusting to the new elevation. Let it run in the new elevation and it should be ok. The car is ment to adjust as u drive to new elevation when u tralior the car it never gets that chance.
