If you have access to an IDS tool you can load them via it and just pull the tune down after its loaded. Although it will change the vin in the ECU. The way HP does it they vin stays the same.

I...

Post the tune with the updated injector info.

You can lower the maf value but there shouldnt be a 28% swing if the injector data is right.

I am in the process of tuning my 2012 GT500. I know there are a few other guys on here that have them as well. Is there something specific your looking for help with?

I am trying to make sure my SD tables are closer/correct. Reading through this thread I feel like I have a decent handle on it however I wanted to double check to make sure I am thinking about this...

That makes sense. You would be able to see the large swings on on the graphs. I have been following your threads just trying to soak up information.

What table setup for logging did you settle on to finally help? I need to start playing with my throttle body tables to get them closer.

I think I figured it out. I left the stock fuel pressure sensor still hooked up to the vac as I just pulled it off the regulator. I believe it is showing the delta between the pressure in the...

I am setting the pressure on my return style system in my 2012 GT500 and I notice that the fuel pressure that I am logging is 8-10 psi higher than the pressure shown on the fore fuel pressure gauge...

Try changing use VID block to disable.

Are you flashing with the Ngauge or the MVPI?

If your using the Ngauge you should reach out to Jim Ferraro as it might be locked to the old calibration and it thinks you are trying to flash more...

Find a tuner that you want to use and ask them what device they want you to buy.

That is the "hand held" that the end user uses, it just loads the file from the tuner on to the vehicle. The MVPi is the tuning device.

Can...

The MPVi2 allows you to pull the stock file from your truck, make the changes you want and reload it back on the car. HP tuners does not send out base files or do custom tuning. If you are looking...

As far as I have seen on the mustang side, most shops won?t send you a tune to load on via your mpvi. You would need an n-gauge to load one of the tunes. Now if you had an ngauge and loaded said tune...

Sorry I missed that the first go around. Thought you said you added it to the bottom connector.

crap i cant read.

only thing I can think is the 9 v is too much as its normally 0-5v?

I don?t the the coyotes have a coolant temp sensor. It?s listed as 5.4/5.8 only on the ecu pinout.

Forgot to mention that the fuel rail temp is pin 26, the fuel rail pressure is pin 23 on the PCM side of the engine harness and listed as 5.4/5.8 only. I am guessing the 5.0 does not have an actual...

GT500s actually have a temp sensor built into the pressure sensor. Its pin 3 on the FRPT connector C106.

The coyotes (atleast 2013/14 in the shop manual I am looking up) shows .5 hours to replace...

Didnt think about it being an absolute and converting it. I am normally sitting at 17-19 in-hg on the n-gauge with the boost box. Yes I can log voltage for the SIP and the MAP.

It takes its pressure reading from the side of the supercharger post throttle body but before the rotors. the fuel pressure sensor on the rail is connected to the lower intake manifold post rotors...

Both are from the same sensor, which is odd since they are off slightly. I added all the channels with "pressure" in the name, except for AC pressure.

That is using the stock SIP sensor (EGR) on the GT500, I have a 2012 GT500.

I believe on the ECU the top connector is the Engine harness, middle is trans harness, and bottom is the body harness.

Here is the pin outs for a 2011/2012 and 2013/2014.

Your looking for PIN 40 on the 11-14 ECU.

On the GT500 there is a pressure sensor built into the EGR valve. I dont think its a true map...

When I had this issue I had to revert the ecu back to stock with the ford IDS. Where are you located? Someone might be close enough to help?
