Hi all!

I want to remap and defap my lovely 406. I own a Galletto and Peugeot's own diagnostic equipment, PP2000. Here is the original file:
peugeot-406-2-2hdi-2001-pre-multiplex-t6

and here is the defapped file (with ECUSafe):
de-fapping-peugeot-406-2-2hdi-4hx-2001-pre-multiplex-t10

This is what I'd lie to achieve:
- the engine life must not be diminished by the remap and all components must be safe
- better overall engine response and a more pleasurable drive
- better fuel consumption, especially at steady 120km/h since I do a lot of motorway (is it possible to reach 20km/l? I do 18/l now.)
- less turbo-lag
- more torque especially at low revs
- I'm not particoularly interested in huge horsepower gains (torque is more important for the driving style I have), but they are welcome
- slight idle speed increase
- anything else? :shock:

I do not see any particular reason to remove the EGR. Can I do it by software only? Why should I do it? Does it lead to any improvement?

I know it's a lot of stuff. Is it possible to achieve all this?

Depending on the remap you can achive some of things you like, but not all of them.

- the engine life must not be diminished by the remap and all components must be safe - Good remap will never destroy or diminish a good working engine.

- better overall engine response and a more pleasurable drive - It is expected by the remap.

- better fuel consumption, especially at steady 120km/h since I do a lot of motorway (is it possible to reach 20km/l? I do 18/l now.) - It can be done with moderate remap.

- more torque especially at low revs - depends how low do you like to have more torque. To low and to much can hurt the clutch.

- I'm not particoularly interested in huge horsepower gains (torque is more important for the driving style I have), but they are welcome - A remap will bring torque and horsepower. They go together.

- slight idle speed increase - Only one map needs to be changed to increase idle speed.

I do not see any particular reason to remove the EGR. Can I do it by software only? Why should I do it? Does it lead to any improvement? - EGR is clogging the engine. When you block the EGR your engine will use only clean air and not gases from the exaust. EGR can be turnd off by software. You need to change only one bit in the hex dump.

First of all, thanks for the reply!

Perfect!

More good news! This is one of my most important goals 'cause as a student I do not have much money to throw away in diesel!

It is rumored that the common 2.2HDi remap leads to almost 400Nm of torque. The clutch is holding fine to that. However, I have heard that that remap is not done very well. Would 400Nm be obtainable?

I knw, but one could ask the engine for more torque low down and leave almost unaltered the high rev response (and thus the max power). Am I wrong? :?:

Good!

Is it needed to deactivate the EGR in the BSI too? Do I need blanking plates? Would blocking the EGR lead to better fuel consumption/more power?

How should I proceed? I do not even know what kind of software I should use and how to do it. The admin (ecuedit) once mentioned something called winols? From the net i gather it can modify maps. Is this the only software I'll need?


Thanks, and sorry for all the questions!

You can achieve a lot of power and torque from 2.2HDI. 400Nm is obtainable with some hardware modifications. 380Nm is more realistic for stock engine.

I knw, but one could ask the engine for more torque low down and leave almost unaltered the high rev response (and thus the max power). Am I wrong?

No you are not wrong. It can be done that way.

EGR is deactivated only in the hex file. You can use blanking plate if you like, but the easyest way is to just block the vacuum hose from egr solenoide to the egr valve. There will be no vacuum and the egr valve will be always closed. It is hard to notice more power or better consumption with blocked egr.

How should I proceed? I do not even know what kind of software I should use and how to do it. The admin (ecuedit) once mentioned something called winols? From the net i gather it can modify maps. Is this the only software I'll need?

It is the best software for remaping, but is very hard to use for a begginers. You will need some time to learn to use the software and then you can try to do a remap.

380Nm is plenty for me. Out of curiosity, which kind of "hardware modifications" are you talking about?
I'm usually very good with computer and software stuff, I had the passion for informatics since I was young. However, from what I read and see it seems pretty difficult to use. Is there a guide anywhere?

Another problem is the fact that I do not have the software. Could one obtain a free/trial version, or something like that, just to try it out?
Is there any easier software to use?

hi there,
you can take a look at this manual.

thanks, I'll have a look at that

The hardware modifications are: bigger turbo, bigger intercooler, deFAP, deCat (replaced by pipe), bigger injector nozzles and a remap to control the new hardware. With all of that you can brake 200hp and 400Nm.
With stock hardware you can get to 180hp and around 380Nm.

Well then apart from defap I'm doing nothing of it. Did you ever do those modifications o a 406?

you should get rid of your EGR to.
