Wanna bet your paycheck on that .

It was even easier to tell what it was if you got an early one before the fancy aluminum covers were done!

You can make your own MAF now using the stock GM element. You are still bound by the output range of the element but the bigger more efficient tube it is inserted into the more readable airflow range you will have.

Not trying to be a smartass, but do you know this for a fact or are you guessing based on appearance? Is it the exact same P/N sensor, and which is it, the LN4231 or LN4232 used on the C6?

"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."

Dave, if the c6 sensor was just "droped" into a 100mm alum. tube the readings from the maf would be way off due to the sensor reading the flow velocity and still figuring that the sensor was sitting in a smaller intake tube, so no you couldn't just easily make one yourself even if this maf is made how you say it is (which i am not doubting as i have not seen it).

LPE does give a recommended baseline MAF value scale that is listed on their Ebay ads. This could support the claim that it is the same electronics in a larger pipe. You would have to rescale the MAF to make it work right. Heck... even descreening a stock MAF needs a rescale in most cases. The MAF reads or reports a frequency. Your vehicle tuning file tells it what the frequency means.

its the same GM racing Stalk Insert Element thats used on the Caddy CTS V Race cars. The MAF scales work well, and its just as good as a speed density tune in regards to HP. I spent 3 days on the dyno with one, and the results rock.

because the back side of the hotwire is shielded from the back, reversion is not an issue like a standard MAF.

Louis,
Is the electric plug connector the same as a 2003 Z06 MAF?

Vehicle: 2001 Z06
Short Block: Sleeved LS6 4.125x4.000, 11:1CR
Heads: LS7 ported
Cam: Katech torquer LS7
Intake: Production LS7
Throttle body: Production LS7


I think the restriction now is the crossover. There are probably more gains to be made with a better crossover and maybe airbox. I don't know what brand this customer has.

No, Its actually larger. LPE provides a harness for splicing/adapting what ever maf/IAT setup you have.

Can you just buy the housing and use it with a stock LS7 MAF cartridge?

The stock LS7 MAF cartridge is very sensative to the housing it is in. It might take some time.

does the MAF comes programed i mean already set and only needs to alter while tuning.

No, It comes with a new MAF scale that you must enter with HP tuners or EFI Live or Ls1Edit, ect. That gets you 99% close, and then you can fine tune the rest.

I've noticed that. I've got the stock ZO6 element in a 4" pipe on a ZO6 that I TT'd. Having a hell of a time getting it to run worth a crap with the MAF plugged in and noone offers a 2BAR speed density for it yet so I'm not sure what to do. Car is going back to the dyno Fri so I'm hoping by some miracle that I figured it out. I'm wondering if I should just buy the LPE unit and tune for that.

So what I want to know is has anyone used this on a C6 ZO6? The transfer function That LPE provides doesn't show LS7 - just C6 LS2 or can the same numbers be used?
