Digifant-1: DIY custom mapping using Tunerpro.

*DISCLAIMER: This is by no means a definitive tuning guide, and specific equipment is required to do any

tuning. The level of commitment is up to the end user. Many of the maps listed in the XDF file are

ÒunknownÓ elements, and there is very little need to play with them in order to do any custom mapping. Do

so at your own risk, I assume no responsibility for accidents incurred while ÒtuningÓ.

SECTION 1: Getting Started

Step #1: Download TunerPro v.5 from http://www.tunerpro.net/beta/Builds/SetupTunerProRT_v500.exe .

The XDF (template) file that is used is only workable in V.5 due to the majority of the development having

taken place with that version of the software. There are many different ways of working with Digi-1, but I

prefer to tune with TunerPro and do any hex editing with the demo version of WinOLS. Hex editing is rarely

required though, since the XDF file allows you to tune many of the available maps hidden in the Digi-1 hex

code.

Step #2: This assumes you have downloaded and installed the above software package. Download the

XDF file required to make sense of the Digifant-1 hex code. It is contained here:

http://www.ecuconnections.com/forum/viewtopic.php?f=25&t=49 . Also download the stock Digifant-1 hex

code (referred to as a Ò bin Ó file from this point on) from here:

http://www.ecuconnections.com/forum/viewtopic.php?f=41&t=45

There are multiple types of digifant-1 bin file to choose from, but the one with the most development is the

one posted above, hereafter referred to as the Ò single-mapÓ bin file. All bin files will work in all ECUs, since

the differences between ECUs are purely code-based, not hardware.

Step #3: Open TunerPro

Step #4: Open the Digifant-1 single-map XDF

file

Step #5: Open the Digifant-1 single-map BIN file

Step #6: Once you have done both steps 5 and 6, youÓll see that in the left-hand frame there are two

selections: ÐScalarsÑ and ÐTablesÑ. Click on the plus sign beside each item and it will expand to reveal the

tuning tools available. The rev limiter, fuel map, and ignition map are the important ones, and the easiest to

start with. For the time being, ignore Òrev limit #2Ó, as it is for the triple-map BIN files, which are not well

known (nor needed, in the authorÓs opinion). The main fuel map is populated in Òduty cycleÓ of the injectors,

so changes to the map should NEVER exceed 95%, and it is a very good idea to never go any higher than

the uppermost maximum currently on the table (91.8%).
