What maps did you copy over exactly?

Today I redid the tune by swapping in only the ignition map and the reengage ignition advance maps, left the VE and the TCV stuff alone. I also figured out the datalogging process and recorded a bit of data. Initial impression is it runs ok and avoids the CEL till the upper end now. I was curious how much boost it would build and it was less than 10psi for the little testing I did so far. I will hook up the boost and wbo2 soon.

I did notice in replaying the live trace data that we are already hitting the upper load cells by 3900 rpm, so I rescaled the load axes to 12.24 using the downloadable rescaling tool but I'm not sure if that was required really or makes a difference without touching the other maps that use that axes. Honestly I need to catch up a bit on tuning procedure as I am in new territory with this project for me, this is the farthest I've been able to get and need to keep learning. I am trying to review the data to determine if the CEL was lit for knock at the upper end of the two pulls I did and if so, where to make adjustments to ignition timing of it would help.

Another thought Im having is that the VE tables are quite a bit different and  would think I should use the LPT map. But then I started to think my motor is even different than the LPT map, I mean wouldn't the VE be different between N series LPT and RN series LPT? Or is the difference likely not enough to matter?

Anyway I will attach my bin and log if I can figure out how to do so.

I compared the VE and ignition maps (Were slightly different) also the turbo maps (duty cycle and load set point). 
I liked how the car accelerated with the -459 vs the -936 turbo maps (I liked the duty cycle map of the -459 more, but kept the -936 set point as a start and modified a bit). The -459 is an LPT bin, but more suited as a starting point, I think.

I I originally had the car on blues (same as your whites) but changed to greens when I was chasing down another problem as a diagnostic (and just left them in).

Ok good to know. The ECU from my car originally was a 460, I don't see 460 bin listed, I did see 459 but I opted for the 609 as turboforslund had the xdf already. I may poke around the 459 or other LPT bins to see if they display right with the 609 xdf. I just want to see other examples.

I also really want to view the .bin from my current tuned ECU and am looking at EEPROM reader for that. Can anyone confirm if this Willem programmer would do the job?

I think the rev5.xdf works fine for the -459. I've also used Motronic Suite to view/compare, but the maps/axes are laid out differently.

Hi,

Had a look at an old post of mine from 2015:

Hi All,

I did check the matching of my previous "609" LPT xdf towards the original bins from Motronic suite. 

It did match all bins except 606, 607, 608, and 612. (note: STD rev5b works with these except the code specific features)

Compability list (please correct me if i'm wrong):  

0261204442, 0261204443, 0261204444, 0261204446, 0261204446, 0261204448, 0261204449,

0261204450, 0261204451, 0261204456, 0261204457, 0261204459, 0261204609, 0261204765 + more unknown.

General XDF for these bins: https://www.dropbox.com/s/mx1hfr3xlcfp3dn/Turboforslund_General_XDF_v1.xdf?dl=0

0261204305 seems to need a 3rd type of xdf...

So, I'm not sure why this didn't come up when I was looking at the AC issues with our 97 GLT, but maybe the XDF you put together for me for the -936 will work for what is discussed in this even older post (I swear that I NEVER was able to find it 2-3 years ago).

After researching EEPROM reading and writing, hot air rework stations, etc .....I have hired a electronics guy to help me obtain the .bin contents of my current ECU. My goal is to first compare the .bins to see what my old tuner actually changed. I am very pleased with how my car currently runs on the tune but given the tuner has long since gone out of business I am unable to have my tune updated for the new turbo, MAF, injectors and pending manual transmission swap. Once I have the tuned .bin I can make sure it's setup right and import the maps to my rev5.bin complete with WB02 and Boost logging, giving me an established base to start from for changing injector settings for Greens, rescale MAF tables for 3.25 ID housing and then tune for the K24. Been reading more and more thread, trying to digest, only a couple hundred more pages of awesome information to go.

Some pics of my current tuned ECU for RN LPT, whites and 18T.

I was able to recover my old tuned .bin file I have been running for years. I have manually identified the major changes in VE, timing and target load maps....but I am having difficulty using the compare functions, to show the difference table values between the two maps while editing. I think it might be due to the .bins having different xdf? All I did was take the standard rev5 607 .bin and swap in the LPT timing map. My extracted tuned .bin wouldn't display correctly with the 607 xdf but it shows correctly with the 609 xdf. When I load the two bins and click compare buttons I get values but they don't seem to make sense but I can't recall exactly how it's messed up and I didn't get photos of that, I will have to follow up after watching YouTube tuner pro compare and reading a bit more on the thread here....

I also attempted to rescale my load axis last time to 12.24 but honestly I only did that because I saw the trace bottom out at max stock load +8ms pretty much right away. However I don't actually understand how that scaling affects things, do I need to change the table values as well after rescaling the load axes? I noticed my tuned .bin still has stock load axes.....

Did you use Piet's "Load Rescaler" program when you changed it? It'll convert the map up to your old load value, and then anything above that you're going to have to manual tune/adjust yourself. It just duplicates the last values for any cells over the old max load.

I haven't used it personally yet, but I do plan on it when I do some more in-depth tuning.

No I didn't, I need to read more on that but that makes sense. For now the axis has been changed back to stock. What's interesting is that my tuned bin shows target load values up to almost 12 but the load axis is still stock 8. So I understand the ECU will use the upper most values for conditions that exceed the tables, mostly by rescaling and refilling the values in the table give you higher definition and finer tuning for the load range you are actually using. A bit confused when I read that the lower half of the axis should remain stock since many tables reference them ....soo mostly rescale and tweak the upper ranges where it exceeds stock values? Is this close to the idea for rescaling load axis?

 Also have been able to move over the maps that were different from my tuned bin to a base rev5 607one bins and flashed to one of my other ECUs. Car is down with a cracked radiator, aluminum unit en route, will test soon.

Was able to use the compare function on different .bins using same xfd, but I couldn't compare between different xdf, the axis get messed up and values don't display correctly in the compare data.....maybe I'm missing something. If I copy the maps to a bin using same xdf then I can compare but that's not as streamlined. So for now I just sorta manually compare, good enough for my purposes but would like to understand what I'm doing wrong.

Here the upper window displays the compare bin data , below is the actual compare bin data. You can see the messed up table data in the upper instance, if you look at the file info the upper instance is viewing my tuned .bin using 609 xdf, lower instance is a slightly modded 607 rev 5 bin using it's matching xdf.

Also received some photos from my partner doing the ECU hardware work. Here is the flash EEPROM being reinstalled on the board of my tuned ECU. Should be good as new which lets me still use it while I get the tune ready for the manual trans swap and K24, etc....

 

Anyway photos of computer parts, simple maybe for some but this was just a bit out of my comfort zone.

1. Cleaning the pads with flux & IPA
2. Tacking down opposite corners with little solder
3. Applying solder paste
4. Heating solder paste to complete the chip
5. Final cleanup with IPA & inspection
