PCV & Autotune
PCV & Autotune
I'm thinking about installing an Autotune on my 2010 SG, I'm currently usning a PCV. According to the PC web-site it seems as if 2 Autotune modules are needed, 1 for the front cylinder and 1 for the rear. Is this correct?

you need the at-100b the reason is the 2010 came with smaller o2 bungs. you can buy which ever version you want if you found a good deal but you might have to weld in the right size bung. Standard size is M18 x 1.5. 2010 SG models have 12x1.25mm(much smaller)

AT
I have AT on my bike and yes, I have 2 modules, 1 for cyl 1 and the 1 for cyl 2. Be careful to make sure you get AT1 on cyl1 and AT2 on cyl2.
I did look at the FM site to see if there were AT changes since I bought mine, but it looks the same.

The older version of the Auto-tune setup was using two modules. One each for front and rear cylinder. The new version now only requires one module and it services both front and rear cylinder. I just replaced my two module setup i bought 3 years ago with the new single module kit from FM. I presented this same question to Jamie at FM before purchasing.
Hope this helps.

I was referring to the difference between the at-100 and the at-100b. I only knew of the system running two separate modules ,one per cylinder. I was speaking cause I had bought the at-100 and it would not fit without welding new bungs.
