fuel cut

At what boost does an 04 dodge neon srt-4 hit fuel cut on stage 2.

i currently have stage 2 with toys and i'd like to know what the tuned ecu is currently tuned to for boost levels


thanks!!!!

 

you're not gonna hit any sort of "fuel cut" you will run into timing issues above 18 psi on the stock turbo

 

The fuel cut is how the car tries to rev limit when you hit redline.


I thought the s2 was tuned a bit higher since you are not out of the turbo's efficiency till about 21psi which is also why they give you the 2 bar map so they can nudge it up a few psi.

 

Renelle,

Being that your S2 w/toys your probably still running the S2 wga. I recommend if you want to increase boost to get the Forward Motion wga. As you can still keep it on PCM controlled boost like stock and keep the drivability as well increase power. The benefits also is that it will hold more boost then the S2 wga unit will. You will want to get a wideband first if your going to increase the boost though to monitor AFR's and make sure your in a safe range.

Not neccessarily true. The car is S2 w/toys. So its got the 3bar map/tip sensors in which case there wouldn't be an issue of timing being pulled at anything past 18.25 like you would with stock/S1 on the 2.25 map sensor.

The stock turbo's effiency is around 21psi. Some run more with water/meth injection. 21psi spike will be perfectly safe with S2 if the afr's are monitored. S2's run pig rich.

Not 2 bar map sensor.

Stock/S1 uses 2.25 bar map sensor
S2/S3 uses 3 bar map sensor

 

even with the 3 bar sensor the car will begin to pull timing around 18 psi

 

Wrong and where is your facts to back that up... Proof?

I have (2) S3 SRT-4's in my driveway that says otherwise.

There is a reason for 3 bar map sensor. There is a reason why they came on S2 and S3 kits. There is a reason why those running SCT or DSP get the 3 bar map sensor inorder to yes run MORE boost. There is a reason for stock and S1 2.25 map sensor is limited to 18.25psi and anything past that it will pull timing. That is 2.25 map sensor not 3 bar map sensor.

If your statement were true no one would bother with 3 bar map sensors. Not the mopar ones, not the PTP ones, not the GM ones.

 

i'm not talking about the car pulling timing from being out of pressure sensor range, but intake temperatures forcing the car to pull timing due to predetionation.
