In the last time I’ve got more and more interested in modifying my ecu to suite various engine modifications. I was wondering that there is not much know how to find in the www. For Japanese cars you can find everything, from hardware like cables and loggers, to free software to make modifications to the bin files. And there is a huge community sharing information about this topic. For Renault ecu such as the Siemens Sirius 34 you can hardly find anything. I already spent hours on investigation to find equipment to do the ecu mapping by myself. I know that for you guys in the UK it is not that a problem, because you have plenty of good mapers next door. But here it’s not that easy.
To start a discussion a made a collection of hopefully useful links.
Software
http://www.tunerpro.net/; nice piece of software that has a lot of functionality. Unfortunately there is no definition file for the Sirius34 available.
http://www.openecu.org/index.php?title=Main_Page; super good software for Mitsu and Subaru. No definitions for Renaults available.
http://www.evc.de/de/download/down_winols.asp; WinOLS. Only the demo version is for free. Can open the Sirius34 bin.
Loggers:
http://www.innovatemotorsports.com/products/lm2.php; nice little logger to log from a wide band sensor and from OBD2 as well. Not sure if it can read the k-line data stream.
Flasher
http://www.autocardoctors.com/new-g...obd-ecu-remap-flasher-tool-p-107.html?cPath=9; Galletto 1260
http://www.fastchip.nl/; tool can also be used to log engine data via OBD2. The guys provide custom tailored files. Software license reveres to a specific ecu.
O2 Wideband sensors

Disassembling:
http://clio2rs.blogspot.ch/; it seem that this Russian guy has disassembled the code and understands the basic functionalities. Unfortunately in Russian…:dapprove:
http://www.keil.com/c166/; disassembler for the C167 Infineon processor
http://mh-nexus.de/en/downloads.php?product=HxD; hex editor

I have no answers for you but I do wanna say; that Russian blog looks interesting! Especially when it's having pics like this knocking about:

I've used Tunerpro for years with 16bit ECU's (eprom flashing) it's a very good piece of software. I've not kept up with it for a couple of years so I'm not sure how well supported it still is.
It's always frustrated me that with more modern ECU's, you can't emulate for live editing in the same way you could using an Ostrich2 (www.moates.net) on old out dated systems.

Definition files are tricky, there are multiple versions of the Sirius34, and all with slightly different locations and file sizes. Location files have usually been written by tuners that have spent hundreds of hours on decompiling, so they're not going to just share. Learn to decompile (I can't do it) or find someone who can do it for you.

Only knock detection kit worth using: http://www.phormula.co.uk/KnockAnalyserPro.aspx
Reccomend this wideband kit: http://www.ebay.co.uk/itm/NGK-NTK-W...070343?pt=Car_Audio_Video&hash=item2ec3e52687
Might be some useful bits on here for you http://www.moates.net/

Thank you Dan for the useful links. The phormula knock analyzer locks like a good tool, even it is pricy. What do you think about the innovate motorsports O2 sensors?
Yes, in the Sirius32 days things where a lot easier. TunerPro for example provided a definition file. I guess with the S34 the problem is not only to find the maps in the hex dump, but also to know what kind of data they show. And then you need to know how to convert the values to real world values that make any sense. And then there is whole story with the checksum…
To be honest, I’m not a software guy and I don’t understand assembler. I come from the “mechanic” side. Building a motor or a gearbox, that is what I can do. But it’s a pity that the whole process of doing everything by myself stops when it comes to that stupid little box called ecu.
It would be great to have at least a hack from the bin file. Why is it working in the evo and Subaru world, but not in the Renault world?

If you want to tune your ECU yourself, get a mappable ECU. It's just better

Was also thinking about that. The KTR Sport GEN90 looks like an alternative. Plug and play and no new harness needed. But before I do the step I will try a bit harder with the fuzzy S34. I don’t like it to give up so fast. By the way, has anybody experiences with fastchip from the Nederland?
