Hello,
Realy good discussion here. I also learn alot from the last 3 pages, but I have a small question.
I got Peugeot 2.0 hdi (2002) with SID801. I removed the CAT few weeks ago and I changed few times the N75 maps to get the engine runing ok, but the question is: what I'm going to achieve if I disable and remove the EGRs? Also, that Peugeot have 2 EGRs. Normal one and Butterfly. What's the difference if I disable both of them or one of them? Please give me some tips what's the point of disabling them. All i know about EGR till now (because I'm still a newbie and learning everyday) is that they put back some of the unburned fuel back to the cylinders.

Thanks in advance

2 EGR ???
Normally you have swirl valve to create swirl in the combusiton chamber and increase the burn rate...and the EGR to put exhaust back in the combustion chamber to reduce oxygen content and combustion temps which create nox.

It was a mess for me to understand why I got 2 EGRs, but finaly I found info about it:

EGR valve is on the rear of the engine and allows exhaust gasses to be recirculated into the intake. This primarily reduces NOx.
Butterfly solenoid is often called a 'dosser'. On this engine it allows air from the intercooler to mix with 'warm' air thus affecting air density

- that's a quote from another forum

On Peugeot Planet they call Butterfly solenoid (dosser) as a Butterfly EGR, so that was my problem, but now all is clear.

Its normally 4 valve per cylinder engines.
One air path goes past the EGR and into one valve when shut.
When open the air can go past both channels and into both valves.
The idea is to set up a tangent airflow in the cylinder walls to spin the air as a column.
The mixes the fuel better so that it burns faster.
Hence 'swirl' valve.

Also referred to as Inlet manifold runner control valve.

That means it has found a potential map there. I've not found it very useful tho, really.

You have to set the reading to 16 bit, decimal mode and then set the number of columns. Then you'll be able to "see" the maps and you'll learn how to recognize them. A map usually starts with:
MARKER (this usually is something like 50xyz)
NUMBER OF COLUMNS (for example 16)
00000
16-1=15 numbers which are the values on the X axis
NUMBER OF ROWS (for example 10)
00000
10-1=9 number which are the values on the Y axis
16*10=160 values, these are the ones you must select and press K to let Winols know it is a map and let it show you the text table and 3d graph. It'll recognize the number of columns and rows automatically, but you'll have to put in the axes label and unit, the offsets, the factor and the the precision. This you have to do looking at the numbers and understanding what they do.

That is one of the best explanations I have seen for map spotting!

Thanks.
