8859XX15 patch to log IPW contributions
Updates
Dec 1, 2009 - Moved this patch from the "advanced fuel control options" thread to its own thread to make room in the "advanced fuel control options" thread for greater detail on how IPW is determined.
Oct 31, 2009 - 1) I have fixed a mistake in the Async Accel scaling in the EvoScan definitions. 2) I have now tested the patch on my own Evo. Works fine.
Oct 28, 2009 - Revised patch and instructions for 8859XX15. Revisions are only to change the logging order of the fuel pulse contributions.
Oct 23, 2009 - Initial post with instructions for 8859XX15
Introduction
As a tool to understand and learn how to better control fueling with the stock ECU, I've created a patch that allows each of the IPW components for an 8859XX15 ROM to be logged. It s very simple patch because it turns out that all the fuel pulse width components except one already get written to a RAM address, so the patch deals with just the one component that does not get written to RAM. The patch is compatible with v5 thru v7 tephra ROMs. I'll be adding instructions for other ROMs later.
Instructions
There are three basic steps:
1) Copy some definitions to your ECUFlash 88590015.xml file. The definitions are below.
2) Launch ECUFlash and copy table data from the base ROM to your ROM. The base ROM can be downloaded here.
3) Add some entries to your EvoScan Data.xml file. The entries are below.
