The m42 has a rev limiter. Its set at 6500rpm.
If you want to go higher just but an aftermarket chip that can make it rev to whatever limiter you want, just dont be surprised when you have valve flotation past 7000 rpm

The standard one works fine, I wouldn't be so hell bent on this launch control either. You will never use it

Contact speedtouch on here. But there are no gains to be had on a standard m42 by raising the limiter by 500rpm.

Chips for an iS are also a bit of a minefield because of apparently non compatible software used on the production run of the iS. I.E. A 'chip' that works on one iS will give poor engine running on another iS.
