Forced Induction on a DI 3.6L V6

-The Pcm does backup airflow calculations by measuring the pressure drop across the TB.THis is the only way to accomplish backup in case of MAF fail due to the widely fluctuating VE's effected by VVT.
-System is Wideband feedback equipped
-Fuel injectors flow 122lbs/hr @ 2200psi (it's rumored that the LLT's are ~96lbs/hr)
-On demand pump has never lost pressure on me, even at 200hp more than stock.
-Pump control could potentially unleash 3000psi and a bit more breathing room on the stock injector.
-System is "torque demand" based. Meaning that your right foot is commanding 0-100% torque. The pcm then calculates the optimum throttle angle, cam angle, and in the LNF's case boost pressure to achieve the torque being requested.
- Is very protective of the engine and will go into halfpower mode when it doesnt like what it sees.
-Individual cyl knock detection.

Wow nice ECU !

I really hope someone confirms those fuel ratings... I'd be a happy camper

You still need pics of the engine bay?

Yessir. Wont be buying one until the "craze" is over and I can just pay MSRP/Gm option2.

Even at 96/lbs/hr they are probably "only" capable of 100hp/hole due to the 1/4 cycle injection window.

its almost like gm knew what they were doing when they built this thing.

The problem with the 3.6L will be head sealing they are pretty much at their
limit N/A................

Do you have a source for this information? Heard the same thing with the 4.0L mustang yet I know a lot of FI 4.0L guys and no issues...
