I'm not sure who's version of XDF files you were using prior, but it looks as if the version you were using was not correct which is why you are now finding this issue.

I was using my own XDF and the labels were coming from external manual just as you have them for some of the axis points. It looks to me like it may have been one address off the starting point as it started with 1500 (second label) and ended with a 0 after 7000 rpm?

I don't want to discount your concern, but please remember the published XDFs have been reviewed by the team and the brake points in our XDFs are correct. Please do not just make comparison to your old XDFs and assume that the old XDF is correct. If you truly find something, provide proof that it's not accurate to include the HEX address if it's a table. I have personally corrected hundreds of mistakes in the old XDFs originally provided by VISHNU. Thanks for your input, please use PM or email me WedgePerformance@gmail.com if you still have concerns.

It's excellent that there are finally some verified good XDFs.

Can we get Metric versions?

jyamona added several IJE0S tables related to knock sensitivity and I ported them to I8A/INA/IKM. The first new tables N54 added since a long time
That said, this is dangerous stuff so use with caution!

+1. Modifying those tables without knowing exactly what you are doing is a risky move.

Other than that, more updates coming soon

The cold start max duration has been added to the xdfs.

Please specify in the first post to download them from Githibas .zip, otherwise Tuner Pro cannot load them.

Its typically 60s isn't it?
So if you set it to zero then there would be no cold start at all (raised rpm, ignition etc)?

65s, 60s on old software. I think the behavior is crystal clear.

Is there a list of all the new tables that have been discovered and mapped? I haven't been watching that much as my Cobb does what was needed for the backend but looks like I'll have to switch soon with all the advancements.

This is a question for everyone..

With PPK1 it's just a flash tune. Most people say that the best part of it is the sound. Is it possible for us to figure out what BMW has done with that PPK1 flash tune and apply it to these backend flashes if someone wants?

on 2 different bin for my MSD80 I8A0S I found with tunerpro differences between address 73C3E and 73C5D

These are undefined in the last XDF.
Could you tell me what it is? and add it to the XDF?

The xdfs cover like 5-10% of the map area. The rest is yet either unknown for now, or not needed for tuning purposes. There are many many OEM maps, 100+ just for i8a0s.

I'll defer to Martial regarding this as it could be a conflict of interest doing a PPK option due to the fact it's a BMW product which is sold by the BMW dealerships.

I can tell you the stage 1 was loosely based on the PPK mapping with some minor changes to hold a few psi more in the upper RPM range.

The stage 1 FMIC is not based off the PPK.

So what do these tables do? Are they car specific (depending on MY and model)?

Sounds like these are the tables we can add/delete features in our ECU, such as making the cold start ups last shorter amount of time?

TIA

All cars are covered through the 4 ROMs. Knock tables allow you to adjust the timing corrections. Yes you can adjust the cold start amount of time from the default 65 seconds.
