there a limit in Hz for 1g mas?

The ECU has an embedded airflow cap designed to protect the motor in the event of a failure, such as the wastegate not opening. If the airflow seen by the ECU exceeds this value, it imposes fuel cut. For example, the 2g ECU's airflow cap is 2.55g/rev.

A boost leak bleeds airflow from the system, causes the turbo to work harder and flow more air to compensate for the leak. Because of this additional airflow, it's now much easier to hit the ECU's airflow cap. Fix the leak, the airflow numbers return to normal and you no longer hit fuel cut.

I love that this turned from a 1G mas discussion to a 2G mas discussion :P

yeah, but I get the idea... around 2000 is about what you can do, I used to pull over 2200hz on my old AWD 1g, but It started being funky, i assumed it was just too much air for that sensor. Sounds like I need a 2g one soon.

This is all kinda new to me too. I never even used a 1G mas, I've had speed density up until recently.

I see. I should brush up on my stocker info. I've run Link/GM MAF and AEM for a long while now, I forgot a lot of what I learned.

I used to run a very hacked 1G MAS on the 1G Talon until last year when I switched to a 2G MAS. I think I was running 26-28psi with a 50-trim turbo with the 1G MAS.

Well, I had one for a little bit in 1997, I hacked it with the free mods of the time and cut the aircan. I never had any fuel management on that car though. I bought my GSX in 1999 and it came with the VPC, I never looked back. To clarify, I never got to really tune with the 1G mas, I did all the TMO stuff in conjunction with the VPC.
