I have come across these tables.
Axes is mg/str vs rpm = crank degrees IMHO.

7500x5000 is typical mg vs rpm axes.

They looked like some kind of SOI as many of the values are whole degrees factor 0.023437

I wasnt 100% sure about these 3 tables, although all three are identical.
So left them out.

I am not convinced they have anything at all to do with boost. :wtf:

So I Think is correct only change egr table setting to 1500, without touching egr duty map. 9% should be closed (parzialized) more than 15%.

I have never got mine below 20%.
I wil investigate when I get more time.
:thumbup:

Looking at N75.
Will look at egr hysterisis soon.

I think that driver of ecm titanium wrong name this should be injection timing (advancess injection timing) :think:

You're an electronic angel :angel: :thumbup:

Any news about Hysterisis :) ?

I would like to know something, If you know...why my car seems to slow at full load and at half throttle I feel more power?
100% throttle my car is more slow than 50% ...where is the problem?

Squeeze the throttle instead of stamping or recalibrate VNT.

1. 100% pedal the turbo accelerates too quick in gears 1/2/3 and overshoots.
PID cuts the boost.
MAF drops.
IQ is cut.

2. EGR sticks.
EGR remains part opens when you go full boost dumping some of the pressure through the EGR valve.

3. VNT sticks.
Delay in the VNT closing makes the turbo accelerate later and more aggressively.
Turbo overshoots badly and is cut [see 1]

4. Drive by wire isnt particular brilliant.

Hysterisis....no for a few weeks

Been recalibrating the VNT for 3 weeks.
Managed to do 55mg ~ 75mg.
75mg was erratic.
Turns out the silicon bend to the manifold had persished and degraded.
oil was dripping under the joint where the boost was leaking.
So I have to calibrate the VNT from scratch again.
But not until I get an alloy bend welded where the spigot is :wtf:

Thanks for the replies! :?

So it is not easy to find a simple solution.
I think this problem is also present on a car not remapped but it's just less obvious.
Honda release an update (for civic DPF) ecu it is have been retouched a few turns on the management turbo,
I dont know' if you can help it, maybe to solve this problem. :think:
They have changed the brake point in turbo table :o see EE1F8 table 75 mg max from old b.p. to 70 mg max new bp.
Can you made XDF only to compare this new management with the old? :geek:

I don't know why the other 2 table of turbo map EE43c no value :shock: and the last was the same :?
