Anyone have EFI Live? I am trying to install a Z06 MAF, but the guy who sold it to me said I needed to change these tables:
{C2901} MAF High Frequency Fail 1
{C2903} MAF High Frequency Fail Limit
{C2904} MAF Low Frequency Fail 1
{C2906} MAF Low Frequency Fail Limit
{C2907} MAF Test Min Engine Speed
{C2908} MAF Test Min Run Time
{C2909} MAF Test Min Batt Voltage
{C2910} MAF Test Max TPS
MAF Rationality test
The actual maf scale
"All those tables have to be changed in order for the maf to work on your car"
I am trying to find these tables in my Tuner file, but cannot find them. I really have to change all this?
Thanks!

idk about changing those....
scale the MAF to whatever the stock Z06 MAF is

That's the problem...I installed the maf, made the changes to my file, and the MAF reads 0 when I try to scan it. This guy is saying I need change all those things in order to make it work???

Yeah, thats what I thought. It runs fine when it's plugged in, but reads 0. This seller insists I need to make those changes for the MAF to work...he also tells me he is a professional tuner. So he must be right...

the tables you are looking for are in the MAF Parametres Tab. Perhaps C2907 is set to high. Do what the guy recomends and then see how it goes. Alternatively ditch the MAF entirely and run SD. MAF's are overated.

What he is showing me is in EFI live...I have HP Tuners and cannot find them. I would like to try to get this working, but as stated before, the MAF should still read...the car will not run good, but it should still read something.
It's strange, the IAT is built into the MAF sensor. I can read the IAT but not the MAF???
the IAT is just like a variable resistor...the car reads it straight up for what its value is.
the MAF however has parameters and values to it. they essentially work in a similar way, both 'read' the air. the MAF tables should be in HPTuners and should be easy to find...i don't have hptuners so i can't help. hit up HPTuners.com
ask and see what MAF settings you need to use. I would think that your STOCK values for everything but the actual airflow values for the MAF would work. so you just need to find those Z06 MAF airflow values. its not making sense why it doesn't work to me
is the MAF messed up? how are you reading the MAF values? through a PID in hptuners? just take a look at the DATA if you can from HPTuners and see if the MAF values are changing.

I know where the MAF settings are, and I changed them to match a Z06. The MAF just doesn't work, I have tried two connectors, it has power. I am reading the MAF through tuners scan tool, every time the MAF reads a big fat 0...
Just got an email from the seller, he said he would refund my money when I ship it back too him...sounds like a stand up guy...

What paramater are you logging with the scanner that is showing 0? Even dead MAFs don't read 0. What adapter are you using to convert the 5 pin MAF to your 3 pin wiring harness? Post your log file here with the MAF reading 0.
I'm not sure what's going on with that gauge display shot because your MAP is showing 0 too with the rpms at 862. Can you attach your .hpt file here so I can see what you did to the MAF tables. In the table display it is reading 0.19 lb/min. What is the dynamic cyl air showing on the scanner and also log MAF Hz. Do those change at all when you rev the engine? do the lb/min change with revs?

No nothing changes when I rev. I scanned all the MAF perimeters that tuners has...still reads 0.
Here you go...I changed the MAF cal, MAF fail freq set it to 13500, mine was 12250 stock.
Thanks!

It's not working....
Here are some pics of the stock MAF
Like we talked about before...I will be shipping it back to you.
Thanks,

This is how you set the MAF to fail in order to get into SD mode. You should not have to do any of that in order for this MAF to work in your car.
