TDStuart Tuning Adventure

[Pistol_91]

Welcome to self tuning. You opened up a can of worms here. Would be easier on you if your car was closer to stock. Messing with SD will take you down a massive rabbit hole. I have spent months and multiple different processes trying to perfect SD and it's not something I think you'd wanna dive into. I would take advice from the guys here and do the easiest changes and methods first. Either change your air box to stock or change your MAF sensor, or both.
When I was choosing my injectors, the first thing I did was buy from a company that had proven and correct data because that's a head ache dealing with bad data.

I would rather put the stock injectors in then do the cai to be honest.

Swapping the maf sensor shouldn’t be too much of a headache.

Hopefully not. Just make sure you face it the right way LOL

Haha ya. There might be a bracket that wraps around the maf which means I need to unbolt some stuff but hopefully I don’t have to pull the whole filter element out.

Not exaggerating that the PMAS cai is a pain. It’s like why am I spending this much effort for an air intake

Did you try changing the WOT start stop?

Naw I went gokarting today and am at a concert lmao.

Tuning will resume tomorrow. I think I’ll swap the maf sensor, see if the iat issue of it rising when I floor it is present.

Then I’ll try the injector settings you sent me.

Then I’ll try the things @markmurfie mentioned.

Then we can see what you guys think about the injector logs and maybe I can throw my stock ones in to see how off the maf is. Then maybe I could calibrate the maf with stock injectors and switch to my lu47 injectors and calibrate the injector data. I wonder if I called ford performance if they could give me a clear answer

 

[K4fxd]

You are going at it backward. Start with what Mark suggested. If changing that parameter fixes it it tells us a lot.

Problem is there are 5 or 6 sets of official data for LU47's and none work all the time.

Does PCMtec have a free editor software you can download like HPT or do you have to buy the product before you get access?

that's the data Lund uses. Alex has stated that many times.

IAT’s rise when flooring it ?

Just looking at his latest log they stay at 108-109 the whole pull

Lots of people say not to use that data. It’s very confusing haha. They claim it’s for 39.15 psi systems and the coyote is like 55

Ya I think you mentioned it too early in this thread or someone else did. For some reason instead of dropping they usually climb several degrees
