Ignition Dwell - New Definitions

elevenpoint7five · **Posted:** Tue Dec 15, 2009 2:57 pm

Hey everyone, I have been working with JSarv doing some disassembly of the 16bit ROMs. We recently found the ignition dwell times and I have defined them for every ROM that I had available to me. There are still some ROMs that weren't hosted anywhere for download, if you have one of them, please get in contact with me so that I may define this for you as well.

I did some testing tonight with an oscope and the tables for my car match my test results.

Once you download this file you have 2 options:
1.)Load it into the RR definitions manager and move it to the top of the list. From there you can open your ROM and have just that table visible. You can then make changes and save it, close the ROM, move the official defs back to the top of the list, and re-open the ROM. You won't see the dwell table anymore, but the changes you made will be saved.
2.)Copy the part of this def file that applies to your ROM into the official ecu_defs file.

Sweet! How do you copy it into the definitions?

You need to find your ROM in the new defs and your ROM in the official defs. Then you would need to copy everything between the <table> and </table> tags, including those tags, for the new defs to the official ones. If your ROM is inherited then use what is between the same tags just on the ROM it's inherited from. You also need to copy what is between the <table> and </table> tags, including those tags, in the "16BITBASE" section at the very top of both sets of defs. I recommend that you save a backup copy of the official defs before you make any changes. This can get a little tricky which is why I included the 1st option for those of you that are less familiar with the xml format and the def files.

Is It only applicable for 16bits ROM?
How about 32bits ROM(the DBW one)?

Just 16bit for right now, sorry!

Hey Andy,

I went to copy defs over, but I couldn't figure it out. Could you provide a little better instruction?

Make sure to add the file, NOT a shortcut to the 'def' file. Open ECU editor, open ECU definition (top left), open 'def' manager. Press add .... locate file... Press save... From there you can move the file up or down then press apply/save to use the top 'def' file. This is with Vista.. I haven't tried with XP yet but they should be similar. No need to add to the main 'def' files unless you plan to spend a lot of time changing ignition dwell.

This is the correct method for XP as well. You can also do the copy/paste thing, which way are you having trouble with?

Is updating the dwell defs a requirement for running the Group N ROM?

No, you need to determine which coil packs you have, that's the deciding factor.

Yes. The SD rom ignition dwell settings are identical to 05 USDM settings. The 05' models use grey coil packs.

I used the 02' USDM rom dwell settings and raised it .62ms across the board and it feels incredible.

is it possible to find a knock vs volts or knock treshold table base on volts ....i think that table should be a Must for Built Engines and to actually filter real knock.....it has to be in there somewhere.

finding a knock sensor sensitivity table would be epic.
