    He can do the 07 as well. It's mail order but will be self based via a cable if you prefer.

    Hi
    I flashed my 300c using a flash loader I bought from celtictuning.co.uk ( see website for full description) I loaded my ECM into the loader and sent the file to them, they inturn sent a flash to me via email file which I loaded into the loader , I attached the loader to my OBD II port and followed the on screen instruction and presto a flashed ECM. Do I need EFI software to do what you mention loading via cable. Is this a Canadian shop that flashes the ECM? Have they come up with something as simple as Celtictuning?

    He provides software to burn your module. Just need the cable and a laptop.

    OK, is he independent or has he a web site for this? a email so he can explain the process. My 300C was the same, I had to download the software to my laptop, but I had to load the flash into a device which connected to the OBD II. Need complete info, so if you can PM me or post it here how to contact him.

    I was going to do this , but the more I drive the SRX the more problems come out of the woodwork so to speak. For now I need to save for up and surely comming repairs. He wrote to me and sounds professional, but if you can get a dyno before doing the tune and after you will see if any changes have been made.Its OK to sell a tune but without a before and after result, its just a placebo effect, and the fact its a always "up to" gain so it could be a gain of 1 HP to the advertised "up to" gain. The dyno will show.

    ^I know that feel. In the back of my head I want to turbo this thing. But every few weeks something new goes wrong. I have no idea how the transmission would handle extra power, seems pretty poor as it is.

    IMO I would avoid the transmission tune, but the ECM tune should be no problem. I am giving the car another 5000 km(after intial repairs) and if nothing goes wrong and I can sort out this electrical drain, I will go for the tune
