Not sarcasm, I've taken an interest and you do seem to be getting somewhere. What's next then? Have you compared the other maps in T5 cars? KFZWOP and KFZW are detuned if ur starting on an LPT, then maybe revisit PED IOP and IRL to get the power delivery you want if your boost limits are now high enough.

I don`t have a proper defined file for a T5. I have tried comparing with WinOls but it does not seem to work. Maybe you can help?
My understanding is that WOP does not need to be modified?
KFZW- My understanding is that I would need to LOWER timing at higher loads and rpm? Or keep same and use 94 Octane? I know that without a proper dyno and logging its impossible to get timing right so I would rather not play with it except to make sure not to melt the block.
What do I need to do for PED?
IOP and IRL have been modified. No interventions.
Fuel injectors have been tuned.

If you've defined your car and have bins for others you've got it all. Look at what Volvo did. Make changes and see what happens, it won't let you melt the block.

I modified hpa axis in IMX to 1000 on the last colomn, and the 2 before that respectfully. Kept the map data the same. Took the car for a drive and after 2 days boost builds to 14 psi and tapers off to 10psi towards 6000rpm.

Not sure I follow here, but if you've left the map-data the same for that table then you will not see any positive changes by just changing the axis. If your max axis value is for example 800 mbar, but you request 1000 mbar of boost then the ECU will use the values in the 800 mbar column. Now if you change only the axis, then you will get the same I-input in the 1000 mbar column as you previously did in the 800 mbar column, but if the boost request is now 800 mbar you will get less I-input than you did before, since you've left the map-data unchanged. You need to scale the whole map (or area in which you changed the axis) so that it now fits with the new axis. Hope that makes sense.

this is what I did. I am still experimenting with it. (KFLDIMX)
My LDRXN will look like this now.
Dont mind Y axis in LDRXN. Its not defined.

You should move the map-data for the 800 column so that you can tune the I-part in the 1000 column if you do not see the expected boost for that boost request. See illustration.

Do I keep map data the same for 1000? or does it make sense to increase, even if its above 100%

great thread, I've read through a few times and I saw it was requested but never posted. Does anyone have an 04 S60R or V70R auto ECU bin file?

There are quite a few different 50WRHJ variants.
