Hesitation in boost and high rpm

[polskifacet]

You didn't happen to see what your torque output was on that dyno did you?

Still havent given me the dyno sheet.
Here is brads tune with voltage. Tried everything to reproduce trans issue, cant. Will post 3rd gear shortly.

Ajp 3rd gear

Unfortunate that there is no pid for HPFP voltage or something with how the solenoid is working. I was hoping that LMS might do some advanced troubleshooting but that obviously didn't happen. I am still having trouble believing its a hardware issue since with AJP tune the fuel rail pressure is smooth enough & strong. Yes the throttle angle decreases in lower RPM but it opens up towards the higher rpm where the pump has more cycles to keep desired. It is also troubling that the LMS tune is making my trans puke while AJP tune does nothing even close to puking. I'm more frustrated after the LMS visit but I won't give up even though it would be easier to just go with AJPs' tune. I do not wish to shed a bad light on LMS but I have been reaching out to them every day since the visit and still don't have any answers or a game plan on next steps.

You are on another thread about the trans issue with the LMS tune, similar to the trans issue I was having... I went ahead and talked to Anthony about the issues I was having... he sent me back another tune for the 4+X (about a week later...) that is labeled softer shift... loaded it today and drove around.. so far so good.. but it usually took until the trans adapted before I started having issues... so we will see.. if it fixed my issue with their tune might fix yours??

And Brad said he thinks there is a hardware problem with yours in this thread.. he can control how aggressive the throttle steps in to keep your load under control... I have a winter and summer setup through him and the difference is how much the throttle steps in....  in any event... I would trust Brad.. he probably spent 10X if not more time than LMS going through the data he got off your car... if he thinks there is an issue outside of the tune, he is probably right....

Have you datalogged the car stock to see what things look like?

I am not trying to be a  **** really, and I understand your frustrated... but you have two well respected tuners telling you the same thing...

I would wait for LMS.. are they even responding to your inquiries? If not, maybe take it back to Ford and have them take a look at it... they did the motor swap right?

Be nice to have access to the Ford Parts bin right now, for test & toss day.

I have a spare LPFP, FPDM, and HPFP... if you need one to test, please feel free to let me know. I will even cover shipping there and back...

Great discussion so far but let's keep the vulgar words at Bay,thanks. Z

My apologies, however, I must say... I was referring to my self with the profanity... so it doesn't count...

Nothing against Brad or LMS but saying something is broken without being able to back that statement up with what is broken, isn't good enough. Stock logs attached, wow the car feels different. Just from what I could quickly see, throttle plate is aggressively controling load and wastegates never open all the way up, I forget which log but there was a 36 psi spike on the sensor before the throttle body on one of the tunes, that just doesn't seem efficient. Open to all suggestions, thanks guys.

Retract my statement about wastegates never opening completely and boost spike after looking at all 3 stock logs.

I feel your frustration...wish i could give give a better explanation to "back up" the statement with what is broken...im not saying something is broken necessarily. But something is amiss

Even in all the strategies ive seen none of the changes are in the fuel pump sections..often its really small insignificant things

What i do see is a fuel system that stuggles at a boost level where nobody else's does..ive never had to use the throttle that aggressively to control boost at that boost level.

Ill look but i dont think i have tuned anyone else with your strategy but i bet LMS and unleashed have so if there is a duplicate strategy out there that is tuned we should get them to post a log then we could rule out the strategy being the problem

Its just i have seen enough logs to know that that boost should not tax the fuel system and show the symptoms yours does so i have to say its a hardware problem....could i be wrong, sure...actually hope i am

Looks like a completely normal stock log to me.... geeze...

Can you post a log of your latest LMS tune? It's crazy that our cars are so similar all the way down to the transmission.

I have been driving the car on the stock tune for the second day and it feels healthier. Throughout the RPM band its obviously slower but it has like a harmony to it, I can feel there is no monkey business going on with it even though from the logs, you can see its heavily closing the throttle.

There was also sometimes a drop in rpm on the LMS tune when i would be coming to a complete stop which would cause a bit of a vibration (rpm dropped) and the rpm would then jump a bit past idle and calm down to a regular steady idle. I can't reproduce that on the stock tune.

Mine does that goofy idle drop as well.

Yea, I can get another one... might take a bit as I have a heavy E20 mix right now so the rail pressure is lower than normal with the LMS tune since they run pretty rich....not a good comparison until I get standard 93 in it...

Lol... I just loaded Brads tune back on it since I verified the LMS tune was ok... which they missed turning of the rear O2s.... again...
