I was under the impression that in softwares that modify the oem code were limited at a max redline of 9999rpm due to the rpm spot in the code being only 4 digits?Quote:

erm...noQuote:

can you post up a dyno plot of the original run without the malpasi?Quote:

ouch, talk about trying to fix a band aid with a band aid.Quote:

lets see the a/f plot before we make any comments.
I have a feeling the a/f after 9200 is fine as peak torque would've been hit before then...
I'm not commenting on the a/f, I'm commenting on trying to fix it with a fuel pressure regulator, and then trying to fix the over compensation with a vafc.Quote:

149kw? Engine Dyno or at the wheels?
If you have a 149kw B18C motor, that has been fully rebuilt then lucky you - But it will last about 10,000kms before needing a rebuild due to cylinders going oval (if consistently kept at high rpm's).
If that is at the wheels, then you have got one of the more / most powerful B18's I have seen / heard of that isn't a drag racing motor (i.e. still streetable, and when I say streetable, able to drive under 4000rpm).
My B18C is stock and with I/H/E modifications I got 121kw@wheels. The extra 28kw being achieved at like 9200rpm is nearly unheard of (You need a 10,000+rpm motor with an AGGRESSIVE cam to make useable power above 9500rpm). I suspect you would need:
12.5:1 Compression (Unlikely since the car runs fine on a modified ECU with essentially the same ignition maps)
HARDCORE Porting / Polishing to the point where the car nearly becomes unstreetable. Plus all the valvetrain upgrades in the world (as you said you have already seen in the head).
Top of Range Headers / Exhaust / Intake combination - Almost need ITB's.
I don't know man. Show me a Dyno sheet for this monster - If you truly have bought a sleeper then congrats, otherwise something smells fishy.
Pro-ECU - Have you come across a B18C putting out 149kw@wheels?? Cost of build would be more than $20k.
On another note - I want an ECU :P
ewen....you're a fool.
I know it hard, but stop talking shit.
Riiight .. Let me know a B18 with 149kw@wheels at 9200rpm.
The knowledge on australian forums is pathetic at times. Attitudes even worse.
EDIT
ok ok -- Sorry. May be possible at 9200rpm. Would represent about 250-260 flywheel horsepower which is still massive for these motors on the street.
