Knock, what to do?

Knock, what to do?
Today I noticed my knock warning light flash on for second (engine management light as I have a simtek) whilst going in to the higher rev band. The car is a 04 WRX running 346bhp.
Question is what can I do to prevent further possible damage? Talk to a mapper?
Any help appreciated
Cheers

O really? I can't say without going out and trying it but its the higher rev band which I rarely use. Just happen to come across a nice bit of Tarmac whilst on the B roads. It's definitely just one flash and not multiple ones. I'll give the mapper a call on Monday and see if he set it up for shifting, I thought it was only for knock...

When you say Simtek is this the "old" Simtek which is now AlcaTek?
If so then as mentioned the check engine light has two functions.
One is as a det alarm, if its triggered in that mode it will flash repeatedly whilst the ecu is recording excessive knock sensor readings and will be "on" when this is present and off when not.
the second use is for a shift light, if this feature is enabled then a then it will come on as a solid light not flashing and typically be on between 6000 and 6500 rpm depending on your mapper.
