Lightspeed,
I looked in my files that came with my M3W lastnight. The ECU was purchased from G56. I did the programming. The ecu is albe to self learn or, you are able to tune manually by downloading Protune II software from S&S's webiste for free and tune your own engine. It will also self tune in a learning mode. This makes a corrective map as you drive. When you are happy with how it is running you can use this adaptive map to correct the ECU and make the changes it made permanent all via the software. It was very easy to work with. In addition you are able to read trouble codes and everything else that the computer is able to monitor. timing, temps, rpm, speed, idel settings, knock senor settings, O2 lambda voltage, more then you would want to know really. If you are just changing pipes you may not need the new ECU. But i dont know for sure. Mine has pipes, aircleaner and cams. I live in Atlanta and couldnt find a dealer here that would tune it for me. I downloaded the program, read the simple instructions, and let the software do the heavy lifting. If you are thinking about going with a set of cams I have some advise. There are several options available from S&S. Theirs highest performace cams are interferance cams. Meaning that if the timing belt brakes, which it is prone to do, you will hit the pistons against the valves. Their middle of the road cams are non-interferance like the stock ones and will clear the piston if your valve train stops. Hope that my novel here was helpful.

That was helpful indeed. Thank you.

Scott,
Which cams are you using?

The 569 cams give an extra 10 bhp and 10 lbs ft torque over standard and are a popular road modification. You will need the unlocked ECU, air filter and free flowing exhausts to make the best of these cams. The 618 cams are more for competition use than road and you loose the non-interferance feature if the cam belt fails, probably not a good idea to fit these for road use. A set up on a rolling road dyno is a good idea and dyno operators will usually disable the adaptive mapping facility when the ECU is correctly set up.

I have the 569 cams in mine. I dont leave the ECU in adaptive mode all the time. Once it was running nice i took it out of open loop and switch to closed. letting it run on the map it created. I also smooth out any dips and spike in the map with the protune software. You will find that the ECU will do a good job but you may have a wierd spike somewhere for no reason. This map is shown as a 3D graph and you can manipulate it easily with the software.

Boy would I love to attend a tech session on the S&S software and it’s usage.

Scott, Did you put the cams in yourself?

" ......the noise is just fantastic. The sound now matches the look!"

You are so right Scott and I cant understand why anyone would want to pay so much more!! Magnaflow........ the name says it all!!!

High Noon

Is the Magnaflow exhaust custom made or a standard Magnaflow exhaust?

I believe it is custom made. Someone with great welding skills, High Noon, put brackets on the Magnaflow muffler and put the stingers and head pipes back in place. Good job too!

Somewhere in the vast quantity of information on this website is the Magnaflow part number.
