Where can I get ignition map sample ?

[RD1林台生]

There is no big holes in the top of piston.
But the pistion rings melt into a mass.
In other words, the flank of piston is damaged.

How much timing is safe under boost ?

Regards,
Tyson.

That much timing under boost is probably what blew your engine. You need
the timing to drop under boost. Most of the people I know of running the
Haltech are also using the J&S knockguard, the new version even allows
you to modify the timing curve while under boost

What was the failure mode of the engine? Big holes in the top of the
pistons?
