      Suction pump does not generated vacuum under boost.

      Time to turn up the boost a little. I was seeing 130% inj duty on 12psi @ 4700 RPM.

      1200cc double foggers from USRT:

      I was thinking actual AFR + injection time was as good as MAF readings especially when comparing different setups. And like you mentioned, to get a more complete picture with MAF data I would have to...

      Pat,
      I'm not sure it's worth it for 0.5 psi from idle to 1600 RPM that I lost. Do you?

      Those are boost (Y axis) vs RPM (X axis). Each graph is a before and after install run. One graph is comparing 4th gear and the other 5th gear. Stock = before install, compound = after install. And...

      The problem is that I didn't log MAF before the install. So, I don't have a baseline to compare any new data with. Up to this point we've only been discussing before/after results and existing data...

      I was assuming relative (run to run) back pressure = increase in boost but not an increase in ingested mass air. If that is the case, how does fuel increase? The method I provided above infers a...

      Thank you.




      The car is pretty much a stock 2003 B6 avant 5-speed (stock clutch), B6 S4 front brakes, stock dp-back, exhaust ST coilovers.

      Ah, very good point. How would I be able to see if that's the case without a sensor in the manifold? I'll take a look at the calculated EGT, but with the sensor where it is I doubt the data is worth...

      Low-end spool (existing MAP pressure) in high gear. Same gear starting at same RPM. Notice the compound setup lags behind a little until 1600 RPM the surpasses stock in a big way after that.
      Only...

      Thanks guys :)


      My friend was able to mill the ear down for me.

      Well, at only 14psi it's still too early to tell. But it's seems to be as responsive as stock or maybe even more so.

      I don't have an EGT or pressure sensor. So, I'm stuck with calculated EGT from...

      Yes, and even the K03 spools faster if you can believe that.

      I did notice the K03 needs a little more N75 duty when RPMs are too low for the LP turbo to begin spooling. I assume it is because at...

      Just a quick test of 2nd MAP logging: (same data/run, just RPM vs Time)

      I haven't touched ECU yet. I wanted to see if it would regulate boost with just the existing N75 and LP gate only...

      Ok, instead of taking the car for a test drive after hardware install, I decided to go ahead and get the wiring done for the 2nd map/iat/n75. Because I know I'll want that LP pressure data asap.
