Hey guys,

Huge difference in power at the top end. It took the ecu a few runs to figure out how much timing was needed, and it pulled timing pretty aggressively the first few runs before coming to a perfect place, and the car smells as though it has a much healthier burn. My ECU definetly had issues learning in the proper amount of advance and functions much better with a full advance and retard. No knock during the proccess. I need to get to the track.

I do not want to tell you how much faster the car feels as you would not believe me. It should have no problem breaking the 12 second barrier. I thought that Mike had removed the rev limiter because I kept hitting fuel cut at 7K in first gear. Turns out that the car is accelerating faster than the Tach keeps up and I am actually up around 7600rpm when the tac reads 7.

That sounds awesome

Oh man, I cannot wait...

I am not too familiar with your car, so if I may ask, what powertrain upgrades and mods do you have? I am curious because you say it will break the 12 second mark. That would make it the fastest SVX I have heard of.

I remember LAN saying he was building a sub 10-second car that was breathing methane but I never heard anything else about it.

If only I knew how much power to expect from my build, but I am in somewhat uncharted territory. Hopefully similar though!

All the excitement is gonna make me...hold on....

Video review. Pig rich on the new stage 2 aggressive software, 9lbs on pump gas.

Been a while since this thread was updated!

Any long-term updates? Especially those with forced induction.

One 4.44 SVX with a blower and Stage2,
one 5 speed SVX with cams Stage2, and no blower.
They both run fine.

Nice. I'm actually going AEM FIC8.
What kinda boost are you pushing? Stock internals? Stock cams?

I'm looking to run 10ish lbs, 420top feed injectors.

Mine is not intercooled, running @ around 5 PSI turbo charged. Around 280hp. Performance is effortless - not explosive .

AFR is around 11,5 when open loop, into which it goes rather easily. Stock cat and central muffler - low restriction rear mufflers, but very, very low sound level.

Engine otherwise all stock. JDM driveline with torque biasing diffs at both ends.

I think it is a well balanced package.

The only real glitch is a very low idle speed when the radiator fans are not running..... for example in deep snow the engine may stall if I lift the accelerator off too quickly. Also, the AFR fluctuates quite dramatically when either depressing or releasing the throttle when in closed loop. It goes way up to 15-16 for a second when depressing and way down to 10-11 when releasing. May have something to do with the (change in) recirculation of the compressor air thru the by pass valve - dumping warm air back into the compressor inlet will have an effect on the MAF signal. This is not a driveability issue, just an observation.

Funny thing I have noticed is that the transmisison temp light flickers at extremely low revs (at almost engine stall)..... the TCU loses the erev - signal, I guess

Turbo? gt30 or 35r?
