2012 Charger 3.6 with SRT4 3bar map and 65lb injectors

[Chris5.0]

Has any one done combo like this?

2012 Dodge Charger 3.6 v6
65lb DW Injectors
SRT4 3 bar map (stock map used to get injector data right)

I got the injector data pretty good with the stock 2 bar setup. When installing the 3bar, and changing the Map sensor Linear data to match that of the SRT4 map sensor I get a baro low p0129 code and the car will not fire up. Baro reads 20psi.

If I let the car sit for 10min, go to fire it up but floor it, it fires up and reads the map sensor perfectly fine, but the baro PID still reads high and I have the p0129 code and will not start every time.

I tried looking in all data for a baro sensor or tip sensor but I think this setup might be all inferred?

Is baro learn still on? Could be learning a bad value

I think Iv tried it with every combo of Baro learn on/off, Sensed Map on/off.

The more Im looking it seems its an inferred reading. I could be wrong

[mbray01]

baro learn off would prevent the inferred learn

Does your car have both a MAP sensor and a TIP sensor?

I dont think so.

This is a customers car, I cant find many people that do a power adder on the 3.6 and go with a new map sensor.

These should do it IF it's MAP sensor matches your tune's MAP Linear and Offset.

Sensed MAP ON
Baro Learn OFF
Baro Fine Tune OFF

What are you calling "Stock 2bar"? The Stock 3.6L or Stock Neon Srt-4?

Exactly what "3bar" are you using? The Caliber Srt-4 3bar 5149056AA?

I ask because a 20psi Baro is EXACTLY what you should be getting if using a Stock Neon Srt 2.25Bar MAP sensor with a Caliber Srt-4 3bar MAP tune settings.
