I think possibly an MPPS or a Galetto2 could do it, not looked for a while as we changed our mind about a 407 for now

For your information, gents.

I hadn't appreciated that the egr controls not only let some exhaust gas back into the inlet, but also close the air doser throttle to ensure 'enough' gas gets recirculated.

Now, if I remember the basics, the inherent efficiency improvement a diesel delivers compared to a petrol is because it doesn't have a throttle. :roll:

Since installing the no-egr map, I have noticed a further mpg improvement. Early days, but the first 100-odd miles on this tankful are giving me an average of 50.5 mpg, which I think is amazing. The previous average of 48 mpg over 1500 miles was achieved after removing the air dosers, therefore the latest improvent has to be due to the ecu not compromising efficienct operation for the sake of the egr strategy. (I am conscious that downloading an ecu file resets the 'adaptives', which could also temporarily affect the car's behaviour).

In short, getting your ecu map modified is likely to save you as much or more than simply blanking the egr.

My 406 is now delivering better fuel economy than the HDi 90 Xsara estate I had from 2004-8. :shock:

Indeed.
Is doser operation removed as part of the standard 'EGR delete' mapping process?

Do you know if there's a way to EGR-off my existing (136bhp) map? For the purposes of a true like for like comparison I'd quite like to start off with the standard bhp map but de-EGR'ed...

I think you'd need Winols and some know how, or a study of ecuedit forums. Strongly suspect Nico can do it, (i think he 'doctored' the '180' to become the '200 no-fap').

From what I've read, it's only a case of flipping one bit, (as with the de-FAP), but you have to do it manually. Looky here http://www.ecuedit.com/egr-switch-edc15c2-t31

From memory i think Nico had a tuning company in the Netherlands make the modifications, I've had a look through WinOLS before but have never actually saved a map and tried it, i do have a couple of space ECU's so i could try at somepoint....

I can't seem to find much detail on getting hold of WinOLS, and I'm not entirely sure I'd trust myself to make the modification. I realise it's just flipping one bit, but the checksum issue is slightly concerning. I wonder if I'd do better by asking a couple of tuning companies for a quote to just EGR-off my map, it can't be that expensive to change one bit right? :cheesy:

I'll send Nico a PM and ask for his advice too.

The EDC15 in the 406 is quite easy to work with any very easy to recover from a bricking.

Boot mode is the key, built in (mask rom) that is activated by grounding one of the CPU pins at start up. As it is a function of the CPU you need to burn out the CPU to lose boot mode.
Remember - it only takes a few inches of water to drown a 406 don't make the same mistake I made! The V6 Exec is no more.

So how does it work -- if the checksums don't match on the new map, or something else is somehow wrong, it uses a default map?

I'm aware we're going a bit off topic here, sorry Rich :oops:

There must be some code that operates the air doser's 'EGR position copy', and you'd want to take this out too.
But you don't want to prevent closing the doser on shutdown, or interfere with the intercooler bypass (if you're unfortunate enough to have one)

FWIW, not having the air dosers has made no discernable difference to how mine shuts down.
I reckon it's lack of diesel that stops it, rather than anything else.

Best to think of the "boot mode" as the equivalent of booting from a recovery disk, you can do no more than recover the error.

If checksums do not match, you need to flash with a known good copy. Recovery allows you to do that if nothing else works.

...and now for something completely different...

I've been busy waxing the fish faced frog. Twice, actually.

Had a big go at it on 22nd and 23rd March: washed (sorry, but it was 1 bucket and a wash mitt), dried, then applied korrosol
Image
I was very surprised how much muck this pulled off.
Rinsed, dried, then wiped down with tardis. Not sure how much good this did.
Rinsed again, dried again, then applied Poorboys Black Hole. This is a complete miracle product!
Image
Below is before, above is after. Not a terribly good photo compared to what it actually looks like -- so glossy!
Finally, a layer of Bouncers Fortify... applied in three sessions between showers ](*,)
Image

The next day I set about the wheels. I'm sure they've never been cleaned on the insides. Took me three hours to do all four: wash, dry, korrosol, rinse, dry, tardis, rinse, dry, then Poorboys wheel wax.
Image
After the korrosol it was really clear how much tar was stuck to the wheels, and even with the tardis it was tough to get off.
I was expecting the wheel wax to be much thicker. Anyway, it got dawbed on and buffed off. Wasn't sure how much good it would do.
And here are the wheels after 250 miles :shock:
Image

I had another go at it over the bank holiday weekend, and I'm sold on the wheel wax. The wheels washed up really easily. The wax was clearly still there on the paintwork, so it got a wash, glaze, and another layer of wax. This wax is really difficult to buff off, is this because it's quite hard? On the other hand, it's clearly good for at least a month: is that the pay off?

Glossy!
Image
The picture really doesn't do it justice.
That's Meguiars tyre gel on the tyres, applied with a paint brush. Anther product I'm really happy with.

And here's some beading from this morning
