I decided to drive my car a little and jb4 threw me on map4, the reason was afr lean. I made a few logs then at the first 3 the boost was about 13-16 psi, and everything seemed normal ... but the last log went over 19 psi, trims went on 49, afr to 15.3 ... ign to 0 ... . strange is that jb4 did not throw me on map4 ... can anyone help and say what should i change so that this does not happen .. thank you. I use a translator so I apologize in advance.

I decided to try raising FOL at 70 because trims are maxed out, afr is lean and have bad ign timing ... but my FPL goes pretty low ... FOL is it a reason for this? Or do I have another problem, adjusting logs. No codes and jb4 do not throw me at map4

Looks much better from a trims / HPFP standpoint.

It does look like you are at about the limit on the low end...might want to look into an upgrade.

i want to ask if it's normal after 4500 rpm the boost drops so sharply or i have boost leak. I know the turbo's capabilities aren't great either, so is that normal? It looks like the car doesn't follow the targets of the map6 ,hope you are healthy

Normal for stock turbo to run out of air up top

You can do whatever you please.

Just remember upping boost to a certain point is just diminishing returns.

The stock turbo is pretty inefficient up top, which is why boost falls off, you can try adding more, but its still not going to hit certain target & is just working the turbo too hard.

A turbo upgrade is what most do if wanting more power, especially up top

Turbo is definitely working hard to try & achieve target (still way under, but that’s again a function of the stock turbo).

Cyl 4-6 don’t look very happy, timing corrections throughout.

What fuel?

I’d try and throw a splash of ethanol in there maybe 1-2 gal see if that helps with the timing corrections.

Also, I’d mirror your map 6 settings to the boost actually being achieved up top- wgdc is pretty much tapped & you are just movin a lot of hot air.

Any advice from you is important to me , what you would advise me about map6. I have pure etanol e100,does it make sense from map6 without upgrade turbo, jb4 is a great product and gives so many options for that i try to use at least some of them

Your stock turbo is pretty much maxed up top.

More ethanol may help timing a bit, but youd really need to watch your hpfp / trims as that taxes the fuel system
