Can you Swap ECU

[Frewsky]

My ecu shorted out, can you replace it with a different symbol circle,triangle or square or do you have to match them.

From what I understand the symbols need to be matched up with the injectors. Different symbol, different injectors.

I might be wrong on this though

 

[hatchers]

that symbol is the product of each injector flow rate test, these injectors are mass produced and not all the same, so each one is flow tested with either liquid or air, for arguments sake lets say the square is ideal with the circle testing at slightly more flow and the triangle testing less flow than ideal, get it

but with a turbo kit, im not so sure it matters too much or will matter with every kit as each kit adds fuel with X amount of boost, i would try it, but thats just me

I second that. If it was stock you probably could not do it. You should be able to tune it back in with the control box and your gauges.

I've swapped them on stockers as well with no issues.

Since we're talk'n ecu's..... I have a 2010 m8 and have heard the 2011 map is leaner on the bottom. My A/c dealer thinks If I update it that it will get the 2012 mapping. He didn't think he had a choice.
So how's the 2012 mapping?
I can't seem to tune out a slight rich just off idle but before boost.
It's really not that bad but would be nice if it was gone.
