Dual map ECU?

[ToddM]

Any time is a fun time behind the wheel of a 406 Especially with 180 bhp doggy-style

Now if that quote doesn't appear in someone's signature (Discopol or Puggy), then I don't know what will...

Now then Graeme you didn't check any of my posts before seeing that did you?

it was done in a flash, sadly i have a mental image "Doggy-style" featuring our very own Doggy which im having difficulty shifting, it seems i will have to take my mind out and bleach the bugger to shift that one.

Should've copyrighted that so badly..

Well the chip doesn't look to hard to solder in place and I reckon you could get away with that cheaper, I for one, however have ABSOLUTELY NO IDEA whatsoever how he would be able to make the maps switchable while the engine is working, and as doggy himself said what happens while the switch is taking place? Surely it'd be safer to have two seperate ECUs and just swap them over? What I mean is, get another one (it'd most definitely cost less than 200), download the current map off yours (ebay Galetto or just go in the mapping thread), give it to Doggy for some looney style de-fappery and BHP on one and ECO map on the other, Label them with a black marker pen and stick one in the glovebox. Then introduce that chisel to DAT FAP and depending on what you want to and how you intend on driving swap between the two ECUs while the engine is off. For some reason I don't trust people who are as helpful as that guy sometimes..

This way has some disadvantages. You can not just change ECU, as it contains more info that those in the EPROM. For example mileage. By installing a double eprom all other infos are exactly the same for the two maps.
I do not intend to spend 200€ on a double map with doubtful fuel economy increase capabilities and risking to lock my ECU. I just want to understand what this guy does and copy it

Perhaps the way to do it would be to have both chips actually running but only using the outputs from one, in this way switching between the two wouldn't be such a shock on the system. I reckon you'd soon end up with neither running though...

[OdinEidolon]

the chips are 90ns latency so as long as the switch s faster than that there should be no problem I suppose tho.

[steve_earwig]

So it only takes it 90ns to work out what's going on and act accordingly? I dunno what the problem is then Be one hell of a changeover relay though...

[Doggy]

Let's be 'aving you!

You talking to me?

Say - what?

Yes!

Does he mean me?

No idea

After you then, old chap

No, no, after you

Too late again! B0ll0cks to you lot!

Hello, have you missed me?

[highlander]

Doggy, you don't work for Peugeot's R&D department, do you?

Ah your only real error here Doggy is that you are attaching English manners to the map files

Yes!

No, no, after you

all this part could be removed if they were anything but English, in fact if they were Polish they would have started a fight between themselves by now, fought, hugged and and drank a bottle of vodka to make up before the Crankshaft sensor even knew what was going on

From what I understand as long as the switch is faster than that it shouldn't be a problem, anyone can identify what kind of switch is in the pic i posted before?

How much would you guys think I could gain from a custom map in terms of fuel consumption?
Guesses:

• Stock 133hp = ca 48mpg (this is what I get with half country driving and half motorway)
• Normal 180hp with fap = ca 48mpg
• Normal 180hp no fap = ca 50mpg
• Low fuel consumption ca 130-140hp = ca ???mpg

I have to find out how long would it take to repay the dual mapping.

There's this http://www.celtictuning.co.uk/ct-switchable-system

But it's not "switchable" instantly....

I don't know if you can get improved fuel consumption in return for less power in practical terms. I had the joyous experience of driving mine in permanent limp mode, (where injection volume is limited to 30 ml / cycle), before getting rid of the FAP.

It was S - - L - - O - - W!, but no better on fuel.

[highlander]

Forget the dual mapping! DeFAP your car, remap using Doggy's 180HP map file (assuming your car can support it) and it will cost you practically nothing at all.

Then, you can enjoy your engine as it's meant to be, and you will still be getting better fuel economy. Even better, you will never need to get the cerene additive tank refilled at the main dealer, and therefore do not need to sell either of your kidneys.

Well limp mode isn't actually anything more than limiting the amount of fuel, and honestly I would not expect it to be anything better on fuel economy than the stock mode. I'd expect it to be worse, especially since something should be wrong with the car. A custom map optimizes the timings based on your own engine and, you know that, CAN improve fuel economy, since factory specs are fitted to be common to all engines.

I will of course buy a Galletto and apply doggy's method, but I wanted something more.
I will not remove the FAP since I discovered that the car would probably fail the MOT-like test here. Since this test can be carried over by most authorized mechanics many of them will offer you to pay a little fee and they'll (ahem...) modify the readings to make you pass, but I absolutely do not want to do that as it does not seem fair to me.

[highlander]

OK, so don't destroy the FAP - remove it and replace it with a section of pipe - if it fails the next MOT on emissions, then you can put the FAP back in. Then swap over again as soon as you get home from the test centre
