Fine tuning with an Ostrich & Tunerpro

[soldave]

Have currently got an aftermarket chip made by a guy called Marcus from HS Engineering in Jamaica in my Evo. He is highly thought of among Evo circles and has made me a great chip. Since then I have made some performance changes to my car (Comp Cams, new injectors to go in, and much higher boost). He has said that he can make me another custom-made chip using my setup and logs I send him from Pocketlogger. But he said I might want to consider the Ostrich emulator and Tunerpro software to fine-tune the chip to my car. Was wondering how tough that is to do.

My friend does all my tuning, and while he knows more about the early Evos than I could ever dream of doing, I'm not sure he's used laptop tuning software like Tunerpro before. Any ideas on whether something like this would be easy to fine tune?

Thanks for any info in advance

If Marcus was to provide you with the XDF file for your chip then you could learn what to change in the binary and use Tunerpro to do so then upload the new binary chip image into the ostrich connected to your ECU.

Tunerpro is a generic program for modifying ECU software. It needs a configuration file for each ECU software version that tells it where the things are and what they are so that the user can modify them. It doesn't have any tuning knowledge built in.

The Ostrich is a EPROM emulator. It replaces the EPROM in your ECU with battery backed up RAM and a USB interface to load the RAM. You upload binary files containing the image of a EPROM to it and the ECU runs that software.

As long as Marcus provides the XDF file for Tunerpro that tells where the things like fuel and timing maps are you would be able to change them, reload the ECU and run with them.

Thanks Steve. That's a big help and something I'll talk to Marcus about. Is an XDF file native to Tunerpro or is it a file used with other programs too?

XDF is specific to Tunerpro
