Im sorry, at 8200hz it maxes out at 4063.5 lb/h

I have calibrated the MAF as much as i can but anything over 6000 rpm or 8200hz is maxed out. Its an open pipe between filter and tb.

In MAF calibration high, at 6000 rpm, it flatlines. The MAF is in a 4" aluminum pipe.

05 corvette
13:1 ls2
Full port 243 heads
102mm mid ram intake and throttle body
ss4 GPI cam
TSP log tube headers with x pipe, SLP loudmouth mufflers

I switched to ls3 maf due to intake size....

I got it. It was fuel pump cot coming on.

Yes the throttle petal works with the throttle body. Base idle is set to 900.

Build before had same heads, tsp stage 4 cam, same exhaust, intake and throttle body.

set up on car.
102mm intake and throttle body
GPI SS4 cam morel link bar lifters
12cc dome pistons should be 12.5:1

I sent you a private message 2xLS1.

Should I do the code modification for the speed density 2 bar? If I don't have too I wont do it so I don't accidently brick the ECM.

The patch worked link a charm. My injector duty cycle is hitting 100% at WOT so now I will get a new set of injectors. Thank you for your help 2xLS1.

Thank you sir. I will write entire when I get off work at 1am. I will let you know.

Right now it shows unpatched 1, so I need to set it to patched 15000 hz correct? I havnt messed with anything in the OS. What will that do?

I have a wide band in the car but not hooked up to the tuner. It quit working 2 weeks after I installed it. I'm adjusting the AFR by reading my narrowbands at WOT to 890-900mv. The plugs look good...

Ok, I see that now. Its the factory MAF sensor. I was told with my mods my factory injectors and MAF sensor will work. Do I need to get a aftermarket MAF?

That's when the limiter hits. Its not a smooth action. The rpms bounce 500-600 rpm. If I fail the MAF sensor in the tune, turn off the PE and DFCO off it will rev up but it affects the traction...

This is the current tune and the log about 30 minutes ago. The rpms still are limited to around 5500 with the airflow max vs rpm not exceeding the setpoint.

yours is set to lb/min I changed mine to lb/min. I will keep adjusting my max airflow vs rpm. at 5300 rpm my air flow on the scanner is 52 lb/min and max is set to 47 lb/min. Thank you for your help....

Adjusting my max airflow vs rpm by 1.25 didn't change anything. Still wont rev past 5500. I do see that the max airflow vs rpm in the tune is at 2817 lb/h and in the log at 5500rpm it is 3063 lb/h. I...

This may sound dumb but how do I post my file? I just changed the max airflow vs rpm x 1.25 and I will try it when I get off work at 1am.

I have been tuning my 05 ls2 corvette for a couple months now. It has an SLP CAI, SLP loudmouth mufflers, 1 7/8" long tube headers with no cats. I just put the HPE megadeath cam in it. (615 600 lift...
