Hi, has anyone got a new 08 model sti, we've just encountered major problems with ours, resulting in the lower block being replaced. Apparently its a CPU fault subaru know about but are keeping hush hush. Anybody else have this problem?

Hi, sorry I'm a total newbie to this. I've searched the net and not found any info on this problem. Where do you get your know how? Thought that if there was a problem we would have been contacted. Thanks for the update though

i know someone who had the same problem, supposedly is only present in older models, the software update is already preinstalled on "newer" engines..

as for what ive heard from the stealers, its a problem with the engine going lean when being prolonged to the limiter.

I heard of one UK car that has gone *** melty piston*** and lost compression - got a new short end now - due to this issue.

Scoobyboy - what do you know of the PPP for STi 08 cars ?

I believe the problem is in the ecu map on the standard car not the ppp.. as that map is different and the mistake is not in it.

they didn't set the knock load threshold high enough from what I have been told.. and therefore the ecu is not monitoring for det at full throttle and pulling the timing back as it should etc and therefore damaging pistons..

Not concrete but from a couple of sources and imho disclaimer etc

The best solution is to get it mapped sorry couldn't resist
