VF Tuner now supports '16 -'18 ECU/TCU stock file remaps

Good point. He swapped down to a smaller pulley to drive it harder in an attempt to get the same boost as others get at sea level.The TRD blower is a Magnuson TVS1900 which would pair fine with those injectors. He has a smaller pulley to spin the blower harder which is why the OEM injectors are too small.

That’s a strategy if you plan to never descend to sea level. Standard air pressure at 8000 feet is about 4 psi less than sea level, so to get sea level max boost up there you’d have to spool the charger 60% or more over stock- assuming baseline boost was 6psi.

The ECM delivered to OV Tuners in Korea on Monday but radio silence from my contact there when I ask about it now. Hoping I haven’t flushed $1100 down the jacks.

There are several others running the same smaller custom pulley at sea level and there isn't much concern for making too much boost or power. I was searching for an air density calculator to compare higher elevation/lower atmospheric pressure & lower air temp to low elevation & higher air temp.

Standard lapse rate is 2 degrees C per 1000 feet and about 1/2 psi per 1000 feet in the range we’re discussing. The density recovery from standard temperature drop doesn’t nearly outweigh the contribution from air pressure.

Example -
At sea level on a standard day (15 C air temp, 29.92 in Hg), air density is 1.16 kg/m3

Climb to 10000 feet with the same air temp, the density becomes 0.86 kg/m3

Reduce the air temp by the standard lapse rate to -5 C, and the air density is 0.93 kg/m3.

They found it. Was delivered to their next door neighbors. They are working on unlocking it.

Probably should have, but it’s the same part number as mine (I pulled mine to confirm before ordering) so it should work- but might need an initial dealer flash, that I do not know.

at a minimum youll need to reflash the vin into it if they arent when their cracking. hopefully its the same calibration files and itll just be plug and play

Are there any installers/tuners in the milwaukee/Chicago area? I'm interested in the stage 1 on my 16 lx570. Thanks

Any installers in the Gulf Coast Region--Ala/Miss/Fla?
