well i found my problem, i went to a local dealer yesterday and talked to the parts guy and one of the mechanics and he told me that the WS6, SS, and Z06 use a larger MAF, a 1.5 airflow and the standard models use the 1.0 so i'm guessing the MAF i picked up off of ebay is a standard 1.0.

Jan 1, 2021 · LS1 to LS3 - Card MAF Tune Help I have been working on a new tune for my 99 Camaro 6.0 and decided to change from the LS1 MAF to the LS3/7 Card MAF with a 4 inch tube. After start up, the throttle response on low end is less than desired, breaking up and having a …

LS1 and newer engines use a "coldwire" MAF system where by the air passing over a tiny sensor causes inductance, this inductance is converted to a frequency which is then fed to the car's ECU. This frequency is related to the amount of air (CFM) passing over the unit, these MAF units have 3 pins, +, - and F, the F contains the square-wave ...

Even better you can eliminate your MAF and go Speed Density and have the smallest point be your 90mm TB (or 78mm if you're stock). Cliff's Notes of Calculations: - Stock Flow (78mm Lid, 78mm MAF, and 78mm Intake/TB): 4778.36 Square Millimeters - Aftermarket (95mm Lid, 85mm MAF, and 90mm Intake/TB): 5674.50 Square Millimeters

Apr 6, 2007 · SD Tuning, LTFT’s and MAF Table Scaling Once the MAFless (SD) VE table is correct and the mass air flow sensor is reconnected, the LTFT’s will go positive. Now scale the VCM Editor>Edit>Engine>Airflow>MAF Calibration>MAF Airflow vs. Output Frequency table positive to get the LTFT’s back to where they were when it was MAFless (SD).

Aug 25, 2008 · One thing I noticed between the two scans is that the factory MAF shows a value of 1.26 lb/min at idle, while the LS7 set up shows 0.58 lb/min. At WOT I see 34 on the factory MAF and 23 on the LS7 MAF. I'm attaching my tune, along with a couple of scans, one with the factory MAF, and one with the LS7 MAF. Do the two MAfs use different refernces?

Aug 19, 2011 · Speed density fuel management default (MAF sensor failure). Location of the LS1/LS6 MAP sensor is located on rear of the intake manifold. Mass Air Flow (MAF) sensor The MAF sensor is used to measure the amount of air entering the engine. Idle conditions equal a low air flow, and engine under acceleration indicates a high air flow.
