hi im looking through my file for my ecu on edcsuite and looking at the map and maf files in it,
across the whole board its flat showing 60.00mg on both question is does my car read theses maps?
or does it only use the smoke limiter map by temp?
its a skoda fabia vrs ASZ 130PD

Hi man these are only limiters. if you go higher on the Iq but you do not change these, they will limit your injection, so be sure to change them when you modify a file. if you look at the in the Iq by Map map you will see that there are different values, they are not the same as the Iq by Maf where the whole Map is 60.00 mg/s. this is because most of the Tdi's run a Map based file when they are stock.

Hi mate, i used to have the same question, someone help me so i will return the help :D

So your ECU choose the IQ that will use on this way;

First - Drivers Wish - This refers the IQ to the throttle % that you are using.
Second - Smoke limiter - Your question is here, there is two types of Smoke limiters;
1 - IQ by MAF - This map relates the amount of air that you have (Air Flow) with Rpm and gives a IQ value (lower that Drivers Wish)
2 - IQ by MAP - This map relates the boost you request with Rpm and gives a IQ value (also lower that DW)

The ECU only uses one of those and is possible to you to choose between one or another. The ECU use the one you choose in a map that is called MAF/MAP switch, if you use edcsuite you will find it easily, is a map with just one value, this value refers the map you choose to use. It should be 0 if you want to use IQ by MAF or it should be 257 if you want to use IQ by MAP.

After you switch for the type of smoke limiter that you want to use, you can blank the other MAP.

For example: You put 257 on the switch, ECU will use IQ by MAP, now you put the max value of IQ on every single cell of IQ by MAF.

EDCSuite also shows a "Smoke Map" on the tuning tag, this Smoke Map is the same os IQ by MAF if you look it probably has the same values at the axis and in the middle.

The third and final Step ECU takes on choosing IQ is looking at Torque limiter map, this should be the map with the lowest IQ of them all.

A correct tune is limited like this: DW -> SL (Smoke limiter by MAF or MAP) and then Torque limiter.

**If you dont want to blank the values on the IQ by MAF smoke limiter dont do it, ECU will only use the map you refer on the Switch.

Hope to help, i tried to be as clear as i can by reminding of the questions that i had.

Cheers!

Hi friend does this work on edc15c5 too ;) ?
Best regards

I think that Edc15 have the same build, but you should confirm that with someone with a bit more knowledge.

That's the thing no one with knowledgeably in this wants to give a help

Wee need an expert or a pro knowledge for this so pro tunners help us out

Hey people in edc15 to make more rich mixture you change y axis in smoke limiter reducing the afr for example 16.9 afr to 16.5 or maybe 16? I know that make more smoke but i dont want a lot of smoke, my car runs good but i think probably if the mixture more rich i have more power....

When people says smoke free this is hole map in max values?

I understand correctly that the driverwish values ​​should be a little more than in the smokelimiter, and in the smoklimiter more than in the torquelimiter?

I know this post is old but I'm answering for someone else who may find this. Yes, this is how it should be.
