I caused a power steering code in my mustang by turning the key on with the power steering electrical plug disconnected. The code would not show up with VCM scanner. I had to use forscan to clear...

16 or 17 degrees is about the limit. I would leave your cylinder pressure limit where its at and only add more timing above 5000. Your probably making alot of torque down low, adding timing above...

2020 file

How are you adding timing based on ethanol content? Post a tune for help.

Has it previously been tuned? If so the file could be encrypted, unable to be read. You would have to have a ford dealer flash back to stock, then you can read it.

My E50 tune is a little older, it will not let me compare to yours. Have your entire last row of driver demand 600 ft lbs. Use LSPI high to limit boost. When you hit that it will show popcorn in...

How did you get the AEM to read boost in VCM scanner?

I figured out how do do it with user defined math, GT500 map sensor and used the ac pressure sensor as my input.

Where can I find a 2020 GT 500 map sensor pin out? Part number K2GZ-9F479-A. I am trying to build a temporary harness to measure and log boost on my GT 350 using the AC pressure sensor wiring. I...

Has anyone successfully added a temporary map sensor to data log boost on a Mustang? When I added a wideband on my Silverado I disconnected the AC pressure sensor and used that as my input, then...

Your not going into power enrichment. Not good. You have it set to go into power enrichment at 90%, you were at 80% during that pull. Log fuel pressure and fuel pump duty cycle to see what your...

13-14 GT500 are also 56 LB. I saw these on the VMP website. They are 48mm tall, 2020+ are 60mm tall.

Do they have a ford part # on them? A 2020+ GT500 has 56 lb/hr injectors.

have you called your ford dealer? They should be able to do that for you. My work truck has a speed limiter of 66 MPH.

I can help fix all your problems. Turn off flex fuel. Set AFR to 13. Put all cold start settings back to stock. E30 in the tank. Run 93 if you want, LSPI will reduce boost automatically. Same...

I believe you can do it with forscan for free. With HPT you would have to license every truck.

What is your plan for the DI injectors? Brian tooley was doing dyno tests PI vs DI. When he turned off the DI and did a dyno run it melted the tips of the DI injectors, the fuel was cooling the...

Check to see that your have the latest version of VCM scanner. You can get some weird readings from an older version or try beta. The one time that I saw you get into power enrichment briefly you...

your not picking up what I'm putting down. If you follow my suggestion you can run up to E30 or 93 on the same tune. This is exactly what I do with my explorer ST. My wife can fill up with 93 or...

Would you consider turning off flex fuel and setting your AFR for pump gas? That would fix all your cold start problems. You can add up to 30% ethanol and your fuel trims will add the 10% extra...

What is going to happen when you go back to pump gas? Will you have 25% too much fuel?

Thats how my car starts on E85

I had Lund tune my GT350 on E85. It stumbles on every cold start even in the summer. I mentioned it to them and their reply was "thats how it goes with E85, I added fuel when its cold" It might...

I modified my stock file so it was using the stock OS
