I just wish by now all the info was public ie xdfs. Too many things unknown for the oddball ECU versions, still hard to find but easy to verify if one enters the xdfs with better knowledge

Figure of speech.

I'm just trying to say, from experience, that it's not as easy as just 'restore a backup'. All sorts of stuff is still missing and the EWS would not re-align with INPA, it just spat out errors, I needed an autologic to get it started again.

be careful using it is all i'm saying.

Itís actually easy to make a working XDF from the posts in this forum, at least with the basics for tuning. Mine is basicly made up from basic functions that I used over time and Iím slowly adding more as I see the need for it.

A complete XDF would be nice though since itís really hard to identify the other variables that make it all work, like switch over points to open loop, the maps that control torque change and settings etc. But they are not necessarily needed. Itís also only used for advanced stuff you donít need any of that to do basic tuning on a daily.

The thing is though that without having guidance from a A2L for example itís near impossible as many tables and scalars have a conversion value to them, if you donít have any info it would be impossible to identify them. Or having used a decompile to see the actual functions, all that stuff is over my head really.

And by the way.

There is other ways to construct a XDF. Like the programs the user Schlandt wrote, chipfile browser. It includes a MSS54 tuning suite. You can use this program but if youíre looking for the map locations, fill them with garbage, save them and compare the files with a hex editor, and voila. You have to put in a few hours of your time but who here hasnít?

I just downloaded chip file browser and Windows defender doesn't like it:

Trojan:Win32/Vigorf.A
Alert level: Severe

This program is dangerous and executes commands from an attacker.

Affected items:
file: C:\Users\Mark\Downloads\ChipFileBrowserInstaller_0 .7.8_WinXP.exe

Did anyone else see a similar message?

Hi guys, have been trying to eliminate what I'm calling a "kick" at around 1800 rpm while in coast-off. Basically when in coast-off I'm reading "Free Air" or maximum lean AFR on my Innovate 02, then at 1800 rpms the 02 starts reading in the 14s and I get that "kick" like I just jabbed the throttle. This is really fun when in tight stop and go traffic and have to leave lots of space ahead of me.

So I'm thinking that either the idle motor is swinging open at 1800 or the ECU is disregarding the 02 signal above 1800 with a closed TPS and then starts reading the 02 again at 1800. Either way I'm looking for where I can find the tables to adjust the idle motor opening point and the table for when the ECU reads the 02 when in closed throttle. Most of my tables are in German.

I've tried leaning and enriching the 1800/low load ranges on the main fuel table, no improvement.

Thanks in advance.

Phil.

This is called over run. Ecu cuts fuel until reaching 1800 rpm.

Thank you, can the over run be adjusted, if so do you know which table controls this ? If it's not adjustable how do you guys blend this transition point ? I'm getting a really bad "kick" at 1800.

I'm familiar with aftermarket systems where this is possible but know that with our ECUs it's a bit more difficult.

Thanks for the help, really appreciate it.
