You will have to do your own reading and download some software from the wiki and elsewhere, buy a $20 cable and set it all up. I just want to spread the word and get a local discussion going. Note: This is just a brief introduction, and isn’t standalone. If you get hooked (like I did) and want to do more substantial changes to your car, I suggest buying a wideband 02 sensor (so you can adjust your fuelling properly) and a pressure sensor. But you can record a trip on your car and play it back later. Note that the engine is started, so the values are way off. Logging is one of the best parts of a DIY flash in my opinion. More boost at a particular RPM generally correlates to more load at that RPM (in very simply terms). Load is related to fuel and air going through the engine. You will notice most tables have a load axis. When you want to play a little more, you might want to adjust the fuelling (particularly if you have a wideband), timing, and boost. I would suggest getting a basic tune running on your car before you change timing or up the boost. You will probably need to change the injector constant to match your injectors. There are heaps of parameters that you can change. I just soldered a switch between the two and installed it in the top of the ECU, but if you are just going to flash once, just solder a wire directly between the pins and remove it later.ĭownload the 607 or 608 binary from the wikia, and open it in tunerpro (together with associated filed). You will have to bend the pins around A12 to get to them. Identify the pins that you are going to join, namely A12 and B8. This is not as hard as it seems, all you need to do is be able to temporarily join two pins (to activate flash mode).Īnd fold the lever arm around over the heat sink formations.
I just wanted to create a thread to give some local help on the forum, and to spread the word! Especially when many seem overwhelmed by the hundreds of pages on VolvoSpeed.įirst you need to mod your ECU. Also, I suggest that these be your primary source of information. These both have all the information that you need to flash your own ECU, and I do not take any credit for any of the work.
There is a really good thread (albeit large) here and a great Wiki (relate to the site) here I have learnt a lot about my car this way, and had heaps of fun doing it. One of the things I love doing on my C70 is modifying the ECU.
