Anyone logging this field on a FP Green or a IX turbo? What are your readings? I'm running about 28-30psi and am hitting just a little over 2,000 in the airflow and about 40-41lbs in the lbsMin field. Is 2byte accurate?

 

2byte is a hell of a lot more accurate than regular logging...

Sounds about right. What is you boost level at the airflow peak?

FYI, the airflow and lbs/min reading can be skewed with intakes that mess with the MAF, so comparing to other cars is not always an accurate comparison.

 

Thanks for the info. I get full boost about 29psi @ 4,600rpm. Airflow is only about 1,,800 and about 35lbs/min according to Evoscan which is why I'm asking. This should be where I should see max airflow. The numbers above in the first post were at 7,500 rpm which doesn't seem right.

 

On my stock IX turbo, pump gas:

7000 RPM (2 Byte)
228 Load (2 Byte)
1836 Hz (2 Byte)
21 psi (JDM MAP)
37 lb/min


On my FP Green, pump gas:

7000 RPM (2 Byte)
275 Load (2 Byte)
2222 Hz (2 Byte)
26 psi (JDM MAP)
45 lb/min

 

No your max airflow lbs/min will happen up top at 7k +

What boost is it holding up there?

 

It's only holding about 22-23 lbs after 7,000 rpm. So I probably won't seen 45+lbs/min unless I can hold 26+psi after 7,000 rpm? Is this correct?

Shameless, on your log run, the 26psi and 45lbs/min. Are you still holding that boost pressure at 7,000 rpm? If so, what are you using to control boost taper?

 

Yes, I'm holding that boost @ redline.

I use the stock solenoid, a #65 pill, and a Forge 20psi actuator. Throughout most of the band, I'm 25-35% WGDC and after 6000RPM I ramp up to 60% and then 80% after redline and it maintains 26-27psi from 3700 all the way up.

 

Thanks for the info. I'm going to have to try ECU boost control using either the stock or GM 3 port solenoid. How much boost can you hold with the stock boost solenoid?
