View Full Version : Zafira PSG16 EGR off and tune

7th July, 2017, 11:41 AM
I need EGR off solution with disconnected plug because EGR is broken and if possible some power increase or mappack because I didn't found smoke limiter, boost limiter and SVBL.

Thank you!!!!

Here your file egr disconnected. Guess the tune maps you look for are @

0x16E50 (10x12)
0x16F40 (2x1)
0x16F44 (16x9)

Those turbo related, about smoke can't help.

I want to make an EGR and DTC Off. And at the same time I want to increase torque.
I have winols, Ecm titanium. And I know someone ho can lean me MPPS V18 clone.

I don't know the way to disable EGR.
I search someone ho can explain me the how to.

If you want i could send file where is EGR off and Tuning Stage 2 original and modify there you see how it workes! (With disconnect egr plug)

That is very nice from you.
What do you mean to stage 2? I have a Zafi, stock, with 125 Ps. (HW: 0470504202)
How much Ps and Nm with your file?
How can I do to compare your files?

Thank you very much for your help.

Hello Mariobozze,

Can you send me your files?

I lost previous EGR off files and pass. Can you make EGR off in this file again with disconnected EGR connector and DTCs off (P0400) without limp mode.
Attached same file. If someone give me a hint about smoke limiter that would be great.
IQ limiters are correct?
0D0E0 8x8
0D17C 6x6
0D228 8x8
0D2C4 6x6

EGR solved.

I'me back again. I have finally bought a MPPS. And I have extracted file today.
I need to know how to make EGR Off.
Water-cooling intake is broken and now I have sometimes P0400 DTC.
I also want to increase power.

In attachment the Original file.

Here are the specs of my car:
Bosch Hardware Number: BOSCH0100Bosch Software Number: 24451343 KB
Opel Software Number: 0470504202
ECU Type: PSG16
Engine Type: Y22DTR

I have tried to open it with winols. It found me 97 potential maps.
I don't know on which maps I have to work for power increase.
And I don't find where are located the values to change for the EGR Off by hysteresis.

Really need help.

You want only EGR off or also Tuning?

Here is file!

I need to blank EGR at first. But in the same time I want to increase power. Especially the torque.

16th June, 2019, 02:03 PM
Thank you. I will take a look a little bit later.
For the rest I only need the maps adresses and there fonctions.

Hello Mariobozze,

Thank you very much for the file.
I am glad to see that you went to my rescue.

For the next state, I want to increase the power.
Can you tell me on which maps I have to work?
Or can you edit the file for me?

I have read this section for a while. My file contains other map tables identifications.
I think the structure of my file was used only for a short time (vehicle production).
If you tip the Bosch or the Opel serial numbers on the web, you will find nothing.

18th June, 2019, 09:21 PM

Here is Tuning file!
Pass = same like EGR off

Please push also thanks on this file

greetins :-)

Hello Mario the Boss,

I have written the ECU with your file this morning and tested the car with Egr unplugged on mountain roads for about 20 Kms.

You have made really a very good job.

My first impressions are:
The torque is really present, in some cases I can put a higher gear at same speed.
The accelerations are more progressive. Before I had impression that they where steps in accelerations. This results to a smoother drive.
There is a lot of lesser smoke. I think that is the result of EGR Off
The car stereo works better. I'me joking.

I will let another report after long test drive (flat and high roads) and after I emptied 2 or 3 full tanks. With fuel consumptions.

You're really a great guy. Without you I was totally lost.
Thank a lot.
