Loading on different maps
Discussion
Looking into options for the two stinkwheels in the family (not the 911, lol) I've been talking to a mate who reckons maps can be found on the web (I'm specifically looking at Doblo 1.9jtd and Peugeot 207 1.6HDI)
I have the cable and laptop software, and am thinking of dicking around with the fuelling/boost/whatever maps but wondered if there were guides/examples/etc and better still forums where I can research it for myself.
Things I don't want to be told:
1. It'll blow up because I don't know what I'm doing.
2. I must tell my insurance company.
3. ANYTHING about emmissions/CO2.
Thanks in anticipation!

I do not know about them specific ECU but most modern ECUs need to be hacked into. This will allow you to add any map you like.
And I think you need certain software to create the map in the first place. This is normally expensive unless you find it on the internet.
What i am trying to say is that the mapping is the easy part relative to actually changing the map.
I know you can get them 'Plug in Remap' devices, similar to blue-fin. That may be the way into the ECU, although i suspect they are more resistors than anything in the form of an altered map.
I think I may have gone abit wrong with your question. You wanting to know how to map?

No you've not. Most useful thanks. Yes I want to know how to map. Not sure yet if the software allows me to copy out/preserve my existing to allow me to dick around with it and reprogram it.Do you know anything about adjusting the map?

Mapping is very much a dark art. Theory is relatively simple but in practice its quite hard. Sorry if I sound patronising but I am going to start from the beginning. SM
A map is simply a collection of data spread-sheets. Fueling and Ignition Advance against a Load Site [revs] and Throttle Position.
The general theory is to get as much combustion as you can out of the map. This means you need to burn the most fuel. This is achieved by adding fuel and advancing the timing although if the engine starts to pink you have gone too far. Too lean and you may blow the engine up.
adopting this method also means you will end up with a Kangaroo-like ride. I know my ECU interpolates between load sites which goes a great length the stop this but unless you have experience then as I said before; getting a good map is very much a dark art.
Your best bet is to buy this book -

Its by Dave Walker aka Mr Emerald. That will tell you everything you need to know
You want the bottom software off this page. This is Emerald. Just play around and get to grips with everything.

Mapping & Flashing a modern ECU and modern car is hard. If you are serious about mapping then find on old snotter with a fairly simple engine and go from there

Very interesting thanks. I've been to Dave's place in Watton before, thoroughly decent chap -- he ran my E36 M3 on his dyno and three of us had to get in the back for traction, lol. Not that it was very powerful.
I'll get Dave's book I think, I'm only interested in Diesel though...

There must be a few diesel books out there. Although I am yet to master simple Straight 4 8v engine so I have never branched out to diesel so I cant recommend a book.I'll get Dave's book I think, I'm only interested in Diesel though...

And also melted pistons make a great ash-tray

Mapping diesels is pretty easy really, once you get the hang of what is going on. It's not like a petrol which you'd want to dyno under varying loads to get the AFR's spot on etc... diesels as you will know will run (pretty much) from 0:1 afr to 1:1 afr with complete shed loads of smoke or flooding the engine
The Alfa common rails and the Peugeot common rails in question are fairly logical in how they work inside...
Plenty of good reading material on that site. Work your way through and then ask questions that are clearly not already answered, and people will be happy to help!
Personally I wouldn't pay for random maps off the internet. If you insist on buying maps get them from someone recommended...
PS, I use TunerPro which is free, and you can donate. WinOLS demo is handy for defining/finding your maps, then create the 'interpreter' XDF file in TunerPro to actually edit/save your binary files.
Anyway, that forum will help oodles, so best to continue the help if needed on there
