ECU Remap on Open Source (STi)
 

Hi just would like to know anyone that has mapped there STi using OPen source software. Note this is not a debate on open source vs others or DIY vs a subaru specialist. Just after some people that have done it using open source, etc I will probably then private for more discussion.

Thanks ...

I use OpenECU for my Evo IX, great user friendly interface just very time consuming. Make sure you log log and log some more and only ever make incremental increases in any of the parameters. Get a wideband and have some fun learning and reading and taking the enjoyment of your car to a new level!

Thanks a lot Im in the learning phase at mo and will be on a live tune course with real time rolling road and road mapping thrown in too later this year after that I'll be doing my own.

Just getting to the point now where I will be doing too much mapping and I don't find access to 'Any' Subaru specialist even those that have mapped my car (for basic queries), available. Whether via phone, email or whatever so best to do it on my own going forward.

I will have access to a rolling road from various garages so will log/save map, save, etc. Nothing exotic will be done but enough to get a good drive/eco.

Any sites and info you got please send me all welcomed.

To be honest with you i haven't seen a lot of subaru specific stuff to learn from. However i should imagine that the basics and stages you go through are very much the same. To get a good basic grounding on the system and parameters etc. i would have a look over here. Lots of useful general information if not Subaru specific, at least a good place to start from EcuFlash - evolutionm.net


There are a lot of critics about self mapping, i think if your methodical in your approach and never get ahead of yourself its a reliable, economical and enjoyable way of learning more about your motor and coaxing some more performance out of it. At the end of the day its not rocket science so have a read and get a sound knowledge of the basics of mapping.

To be honest Im not really a believer in self mapping as such as I think the cost of learning far outways the cost of a few maps but if you find or think that you are going to require a lot of maps over the life of a car or several cars then it becomes worth it. Hey maybe we can start to put some things out there for those that may find themselves in the same boat.

I do find (unlike a lot of other industries) that the customer service is lacking in 'a lot' of specialists don't get me wrong while your cash is being taken there is no problem but I find the general overall service not as good as other service providers. We are not talking about hundreds of pounds here but thousands.........<---- Just imho.

I've used open source to remap my 2004 STi, it is currently running about 300bhp and over 300 ft/lbs, my MPG has got better by about 20-30 miles per tank running around and on a run the best I ever got was 330 miles without the fuel light coming on.

Have you joined the Romraider forum? there is allot of very usefull info available.
