Dyno/Tune Issue help please

[was619]

Hey C5er's!
I went to the local dyno today for a group dyno day (24 cars total!)
I have had my car tuned with HPTuners from a well known local tuner(street tune)
The observations:
SES light Codes
P0161 - Heater Condition (Oxygen Sensor Bank 2)
P0056 - Oxygen Sensor
Speed Limited to 155mph (this is normal for a car on a dyno, 4th gear pull)

Previously the tune deactivated the speed limiter and the 02 is tuned out along with the A/F and other things normally done with a tune.

The Mods on My car are in my Sig the main ones here being
Intake, Headers(full exhaust) and Ported TB.
Also its the LS3

Is is possible that my car went back to the stock tune? The SES light came up shortly after filling up my gas tank but I filed it with 93 just not from the same station that I normally fill at.

Any help would be appreciated
Thanks

When your new tune was flashed to the ECM, your old tune ceased to exist. I know you don't want to hear this, but it sounds like some of the things that were supposed to be done in your tune were not.

Okay yea I figured he just didn't get ALL of the Code needed to keep the SES coming on for the o2s
The speed thing is still a big downer being that I am planning on some private road (closed airport) high speed runs. I will be sure to have him look everything over.
Thanks for the input guys!

It's all fixed now.
Had to set a few code to does not report other wise the message In the center display says "service engine soon" instead of the actual SES light.

Thanks guys!

This is why I wouldn't want to go as a group dyno day. As much fun as it would be, I would rather have them take their time with the car and get it done right than to rush all 24 of you on the dyno.

Dyno day should not be tuning day. If your going to set up to dyno day, then do it.

When guys try to make a couple extra bucks and throw something into your computer for a quick turn around, usually get a problem because all of the discractions around you.

If you see something wrong with your car on dyno day, then make an appointment with your favorate tuner to have to car calibrated properly.

When I see shops setting up 5-10 cars for a dyno tune day, run from those. Great money for the tuner, but no time to detail tune each of the car properly low end and WOT.

Each vehicle should take about 3 hours to properly, but ive seen guys tie them down, do a pull or two, change the fueling, and charge $400. in 30 minutes
