Help figuring out changes in free Stage 1 file

by **tecnical** » Fri Jul 16, 2021 3:55 am

In the past months I heve been learning a lot about ECUs and how to make thing happen.

So far I managed to disable the EGR (blanked) and Flaps (they were previously removed from the inlet manifold).

I wanto to learn more and I found online a free stage 1 file for my car (fiat bravo 1.9 jtdm 16v 150).

I compared the original to my original file and it matches perfectly.

Im not going to flash it, im using it to learn. I managed to identify most of the changes, but not all.

In the file, the section $02014 to $0217C have a lot of changes that I cant figure out.

Can help me figure out these changes?

Thanks!

$02014 to $0217C no need to push
1C1A2 - bad, you can change the last fuel axis.
1f27e, ... - don't need to lift like that

$02014 to $0217C is boost.

I agree with Deman.

If EGR is blanked you should do logs to check overboost at low-med revs, then tune VNT.

I know its been some time since last post in this thread, but I need some help figuring out the boot map.

I dont know if its right, but I belive its a 16x16 map (starting on 01F86 and ending on 02184 ). Is this right?
Also, i cant figure ou where both the axis start.

Any help appreciated.

I think you are meaning the boost maps.

The boost maps start from 1F280 in the maps you added.
Even in the original OLS i can't find a reference to the changes you are refering to (starting on 01F86 and ending on 02184)

Leave this stock!!!

Check the mappack i'm adding.
Those should have all the maps that need's changes for a tuning

i would not run this mod on my car...
I hope you are not doing this.
Good example of why you should not use free tunings you find online.

Thanks. Im not runing it, and also not planning to do it.
I'm trying to make sense for all the modifications that are present in the file.

I also didn't find any references to these addresses I mentioned. That's why I asked for help.

Thanks for the help and the mappack. That's very useful.
