well i have a link in my gtr makes 430kw at the wheels, and some of the previous tunes where very average,so its vital that the tuner knows what he's doing,the last tune i had was at advan and its quite awesome to drive with no issues at all,starts first time everytime

Does the link run utilize the O2 sensor?

PFC is a damn good no frills ECU.

6 inj drivers - Sequential inj.

6 coil drivers

Boost control

Injector Warning

Air-flow warning

Knock Warning

O2 Feedback (Closed loop)

VCT Control

fuel cut (rpm, overboost etc)

Perfect cold and warm start

Excellent idle control that rocks ign. timing and utilizes the AAC valve to hold flat idle.

Water Temp Compensation

Accelerator Pump

Airflow (load) and RPM scale is able to be modified

Ign. vs water temp correction

Ign vs air temp correction

Cold start ign. retard correction table to aid in engine warm up and drivability, emissions blah blah

Ign vs boost correction

Ign vs battery volts correction

Ign Dwell vs RPM correction

Anti-Lag

PFC versions are available that have launch control, ign cut instead of fuel and MAP.

What are the tech. specs on the Link? O2 control, inj. and ign. drivers, total load and rpm points available etc?

full ecu or standalone is a complete engine management system

piggy back is exactly that, it piggy backs onto the standard computer.

so parts of the car run through the piggy back and get changed and the rest runs to the normal. you can also get a remap which is the stock computer but with some values changed.

normally with a piggy back you have some limits in the system as you rely on the stock ecu still and you cant change the majority of stuff that a full replacement ecu has support to do

a piggy back is usually a air / fuel computer or ignition computer

a full ecu is a standalone engine management

piggy back usualy around $400 ish

stand alone $1000 +

    • Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!
    • Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.
    • Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 馃槂
    • You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position. 
    • You talking about the ones in the photo above? I guess that could make sense. Fixed (but flexible) line from the point up above down to the hubcap thingo, with a rotating air seal thingo. Then fixed (but also still likely flexible) line from the "other side" of the transfer in the hub cap thingo up to the valve stem on the rim. A horrible cludge, but something that could be done. I'd bet on the Unimog version being fed through from the back, as part of the axle assembly, without the need for the vulnerable lines out to the sides. It's amazing what you can do when you have an idea that is not quite impossible. Nearly impossible, but not quite.
