NEW Lingenfelter MAF for FI... from e-mail newsletter:
several pics on website... more details as well
any thoughts?
New - Lingenfelter 100 MM Mass Air Flow Meter
The Lingenfelter high flow mass airflow sensor was designed as a replacement sensor for GM frequency type mass airflow sensor applications for LT1, LS1, C5 ZO6 and LS2 vehicles. This sensor also fits 1999-2006 Silverado, Sierra, Tahoe, Yukon, Escalade, H2 plus many other GM vehicles that use the frequency type MAF sensors
This is the same mass air flow sensor used in the LPE 600 hp and 725 hp 2005 -2006 C6 Corvette twin turbocharged engine packages. The LPE MAF solves the mass airflow signal drop out problem found on 2005-2006 C6 Corvettes that occurs under high airflow conditions. The large diameter, low restriction LPE 100 mm MAF sensor assembly provides accurate airflow measurement while producing very little restriction,
even at very high power levels. $299.95

It doesn't. It's still limited to 512g/s. The benefit is less pressure drop for high psi apps. Once you get up to 15psi, the stock screened maf shows 1.5 to 2.0 psi drop, this one doesn't.

from the website:
This MAF sensor will NOT work with stock engine programming and requires recalibration of the factory PCM or ECM. The proper starting MAF sensor curve for most GM applications is supplied with the sensor but you will need EFILive, HPTuners, LS1/LT1/LS2 Edit, TunerCat or other similar software programs to recalibrate the MAF curve or have it done for you by a tuning shop or custom calibration company. The proper curves can be downloaded from the Lingenfelter web site under >store>product instructions.
This MAF sensor is recommended for supercharged, turbocharged and other high output engine applications. This MAF sensor is 4.00" in outer diameter. Custom ductwork will be needed to install this in most vehicle applications and is not included.
Sensor is sold under two part numbers be sure to select on or the other. LN4231 is for applications where the connector is at the 12:00 position and LN4232 is for connectors that are located at the 3:00 position.

RPM vs PE for everybody using a maf over 512g/s. Which is roughly 650-670 engine hp so it's barely a stretch over the limit.

It will work with ANY LSX ECM, as long as you can program your own tables.
btw, I just put one on my race car, and it won't run. I think their tables are off, but haven't had time to play with it yet. I'll log some data and dial it up/down in the next day or two.

Does it have a rough idle? AF ratio lean?

won't idle, no throttle response. Threw it on late yesterday, and haven't had time to log yet. Sorry to leave you hanging, but hope to log some data tomorrow, and see
1 If I'm getting a signal at all
2 If it is rich/lean.
