Hi!

I just got my MC21 and opened her up when I found that the previous owner had a M-Max box installed...

So I searched the forums and found that the M-Max box didn't do the 2nd wire splice to the GPS...so "rip out the box like everyone says and do the 2 wire splices " is what i thought...

however, the "Tuning section" says this in regards to the top gears and the GPS splice:

G.P.S. splices have already been performed to 1st gear to utilise the PGM-III's most aggressive ignition curve, but NSR-WORLD.COM strongly advises against this. The advanced ignition in the top gears is seriously likely to cause detonation, the quickest killer of 2-stroke engines!!

Now I'm confused...if I perform the 2nd splice to get the advanced ignition curve to the top gears would be at risk of detonating my engine faster? Or is this just a disclaimer...where all I have to do is keep the bike properly oiled and I'll be ok?

My bike is going to be mainly on the street as a daily commuter...

Thanks!

I think the GPS wire splice uses the 3rd gear ignition mapping on the top gears, hence splicing the wires to the 3rd gear wire. The disclaimer is for those considering splicing the top gear wires to either the 1st or 2nd gear wires, in order to obtain an even more aggressive ignition mapping for the top gears.

ah...that makes sense now...thanks!
must be my preschool level reading comprehension...
