mapping question.

[Snoopy]

Do the mapping company write out the part that allows the ecu to adapt to different grades of fuel?

APR and Revo do

Why would they remove a safety feature?

I misread the suitablty of the op as they clearly do not

they do provide maps which can be switched between to suit the different grades of fuel

[Snoopy]

Now I'm confused.
The reason I'm asking is for example quite a few years back revo did a map for the 1.8t but it was for 98 Ron only.
Nowadays they seem to use there switching device to select for 95ron 98ron etc etc.
But modern oem maps can adapt for both 95 and 98 or protect from poor fuel.
Do these comanys therefore remove this feature the standard cars ecu map has.
Or does there map have the capability to change for different fuel grades.

I have Bluefin on mine, the other day I had no option but to put in standard unleaded.  Since adding it there's been no issues whatsoever.

I think with REVO you have to change the settings using the SPS switch if you put in lower RON fuel.

you're confusing maps with adaptations, the former is set in stone while the latter will do what it says on the tin "adapts". But then i wonder if you're talking about knock control.. which is something else again.
Your original question is rather expansive, can you be a little more specific about exactly what it is you want to know?

[Snoopy]

Basically I was wanting to know what features were effected when a mk6 is mapped.
What features of the standard ecu programming are effected.
Are as you say the adaptation and knock control effected etc.

[topher]

knock control is left well alone as far as i'm aware, as nick said above it's a safety feature. Adaptations aren't really going to be changed but from the point of view you're asking the ignition mapping will be altered so the starting point is going to be offset to suit.
I still don't really know what you're getting at so not sure how to answer Are you asking if your car will suffer damage if its mapped for v-power and you put cheap fuel in?

[RTechUK]

From what I have see on on a stock map on the ED35 cheap fuel pulling timing of -6.8CF a super fuel at 0CF and over 10bhp between them, I would never run a tuned on on cheap fuel.

The ecus have apaption ranges it learns to an extent, but if you do run cheap fuel the ecu will see the timing pull and reduce the power until the knock clears, but as soon as the knock clear the ecu will start to add timing again.  On a tuned LCR this way of correction for the timing eats way at around 35-40bhp on a tuned engine
