Opinions Map Megane 1.5 dc1 101 hp (Delphi)

[franco75]

hi guys, just to learn how to do something I have tried to modify the mapping of this car with the ECM.
I have rebuilt the driver of the ECM on the basis of information found in the network going for the similarities of the curves.
Unfortunately, the delphi is a little, does anyone know how you calculate it on the Breakpoint of the maps of these units?

Please find enclosed the comments of both the files that the driver, in particular, could you tell me if (as per my usual) I overdid it with the turbo?

Thanks a lot

according to me, no ? as bad as the map, but there are a couple of things to fix it, as I think I

the pi? important ? that you have definitely increased too much the pressure of the turbo, 3 bar for the turbine are too many, alzala of 150/180 points to the maximum
I would have increased a bit more? the wide choice in acceleration, but this does not mean that as you did is wrong
ditto for torque limiters, and especially you modificto 1 only on two

[franco75]

In the meantime, thanks for the reply, why? you say 3 bars?
I will follow your advice with regard to the enrichment and acceleration,

The torque limiter that I have not changed (see image) it seems I was wrong and you are not able to understand how it should be.

if you look at the values of the pressure turbo you have values type 3092, 3164, etc
that value corresponds to 3092 mbar, i.e. 3.092 bar

in my driver, the torque limiter ? cos?:

I know that ? better to use the ecm titanium, and not ecm2001

[franco75]

I got the error that the map turbo, from damos, it should be a relief map of smoke

[franco75]

the map turbo for me starts from c61a, I am attaching the image


1749

[magi1984]

you're right, now that I've pointed out, would seem a map turbo lifes to c61a

[franco75]

I hope I get something good reinviandoti drivers ricorretti (thanks to you) in the torque limiter and some other details.
In the meantime, I continue to look at me the damos to be able to exclude the EGR, but I know that it will be? capable of.

[magi1984]

for the egr I have ever worked with....then I wouldn't know how to exclude it
however, I believe that the egr map in your car is to b5c0

[franco75]

I tried the map, everything is ok apart from that in an out-of-revs not wanted (asphalt pitiful and wet) ? released the message "error regulator".
I tried to search for ricausare the error but have not succeeded.

The turbo pressure stabilizes 225.5 kpa absolute, then 1,22 bar but with peaks of 1.5.
How could I do to get to 1,3 - 1,4 constant without increasing the peaks?
There is a map that limits the maximum pressure?

[magi1984]

I believe that there is the svbl, the single is worth the boost limiter which limits the maximum peak pressure... On the bosch ? easy to find, on delphi I don't know. Usually ? the last value of the pressure limiter

[franco75]

I can't find I'm limiter, the car is fine but I would like to make the next step after the coupon that far? in these days.
According to you as long as I can climb the press. turbo? Consider that I do a lot of motorway at high speed because of the 5? a little short

[cinqueturbo]

Inalzare too the press can? to break through both the engine and the turbo, so be careful!

apprate that the pressure increase navigational safety, the temperature of the air turbo!!

intercooler front in the first place...

[James]

if you do a 1.5 peak you are ok, for the constant pressure control on the highway at a high rpm and make sure that no salt but you keep it under 1.5.

[franco75]

thanks for the advice, aumentero diesel only to see how it behaves the pressure of the turbo

[James]

remember, that by increasing the diesel, you will come sooner or later to a point of stalling of the turbo... and what? on the highway does not succeed? more to download the turbo pressure.... then tries to give the diesel with the very policy... c'? also to say that this happens on the machines you want to push a lot. the council ? as long as you're in the norm of increases in diesel, you should not have any problems with the turbo when you start to push ? a good rule is to check the turbo pressure at all rpm's of the motor, but I repeat, the defect does on the highway the turbo fails to download all the smoke and inertia loads more pressure than that determined in the map. I for this problem to fight continuously with the jtd and mjtd which are the ones that I practice more as the car pushes.

[franco75]

ok, if I see increases in the pressure abnormal back-to-back with the diesel

[franco75]

guys I exaggerated a bit the map, in a first step, I exaggerated with the turbo and it was a fault, strangely not at full load but at the met? accelerator.
With the current map occurs the problem that the ta three-quarters and the maximum of the accelerator, the car loses power, but up to three-quarters is really strong (1500)

I think you were wrong to interpret the breakpoints of these accursed delphi, does anyone know how they work?
