only slight issues, no biggie.. :wink: lol...


:lol:

My rule is if it costs under $400 to fix then its not a big deal. :P

Hardly worth mentioning really. Maybe a little less psi's next time though.

Nup, I didnt get a chance to get it on the dyno. It was booked in a few days after I melted my throttle cable and I couldnt get another one in time and missed my appointment. :(

A few weeks back the car was leaning out coming onto boost and it was pinging.

I previously had all those cells in the VE table maxed out and it still ran lean coming onto boost. Jason from TI performance set me straight and told me about the stabilized table but then I had to retune the lot.

Last saturday I was road tuning it in hopes of getting to Heathcote on Sunday but I broke it.

Either too much timing (13 degrees at 17psi), too much boost or the pinging earlier on did some damage and it couldnt cope.

When it was pinging earlier on it was really audible but I didnt hear a peep the day it broke so Im not sure what it is. We think its a damaged bearing though.

The engine is coming out tomorrow for a look.

I only just found the specs for the intake air temp sensor. I'll have it hooked up to the logger before I push the new motor.

yep, au engines are cheap enough now to treat them like disposable nappies,
once they get soiled, throw them away and fit another one... :lol: :lol:
