Renault Master EDC16C36 EGR and MAF OFF

[goyodesanctis]

Hi to all!!!
I have a problem with a friend's garage Renault Master.
When you unplug maf car goes well and egr is blocked by my friend.
I have deleted DTC's above EGR but I don't Know if there are good.

1CC820 16 bit HiLo is dtc table for egr errors P2425, P0404, P0409, P0487 and P0488.
1CD25A in 8 bit is dtc switches for 1CC820.

At the end of file there are some temp maps.
I will share both files.Original and trying EGR OFF I don't know if this is well or not.
Could anyone rate this???

We have errors in maf
P0100, P0101, P0110.

Could anyone check it for delete MAF and EGR and if my work over EGR is good???
Where are hysteresis maps in EDC16C36???

I can't find temp tables like in EDC16C34 PSA.

I hope if someone download file could understand this dtc table and dtc switches.
I haven't find everything.

Regards!!!

DTCs about EGR are deleted well.
Those temp. maps are not EGR related.
You zeroed one 19X1 map... why?

If the car goes well with blanked EGR and unpluged MAF, without limp mode, just delete and the MAF DTCs...

Hello mate!!!
I have applied this temp solution seeing another works but I don't know why.
Perhaps they won't be a solution part.
19x1 I thought it was hysteresis. I don't know if there are some maps of hysteresis and how to zero it.

I have trying to find how to delete P0100 P0101 and P0110 and sequence of bytes and start of directions for dtc tables and dtc maps I don't know.
I saw the correct sequence for egr bytes but no for any dtc's more.

And when maf is disconected car runs well no black smoking and my friend has tested two new mafs and similar result.

For this reason we needed to delete this dtc and I don't know how cause converting 16 bit HiLo to 8 bit I can't see similar sectors.

Sorry for my english if anything can be understood.

Thank you for your reply.

Regards!!!

After 10 min you will have a new file with MAF DTCs deleted...
Here you go... it is your file with P0100 and P0110 off in addition.
No checksum.

I will take a look I will take a deep look to understand, how tables work in this ECU. It has been difficult for me, that I am focusing on this, and I publish, in order to be able to help my colleagues in the forum with file, but I still have not understood how EDC16C36 works.
For me, it's all a pride, that someone like you can help me, and spend your time to resolve this doubt.
Really, thank you very much, I do not know how to thank all this that you are doing for us.
Greetings from Spain!!!
