Hey guys,

I performed some preliminary logging today using Dynoscan. Granted I don't have every parameter we would like to see, but you get an idea what's going on here. I will have more to come in the future.

I didn't log MAP sensor as thats useless since the Z-chip modifies that signal to force the ECU into lower load tables anyway.

Notice no timing dips during acceleration, indicating no significant knock. This was on a 50º morning with 25psi spikes, 22psi steady and dropping to 18psi at redline.

Impressive data acquisition there tsitalon!

How do you like that AFR :) ?

This is a great start to properly using this subbforum.

Excellent work.

Yep, Narrow band was 94-.96 the entire boost range. Great job TTP. Wish I had a WB02, but logging timing and NBo2 works for now :D

If you like this logging, wait until Evoscan comes out :D

Scott, in my experience airflow lb/min is a directly correlative to hp, so would it be fair to assume that I am close to 350hp?

Hard to say. Tune looks great.

Not sure if the ECU takes map into account when metering airflow though.

I hate benchracing however it would appear based on the data that 335-350whp would be feasible.

Ignition timing looks just great!
You REALLY need a wideband. Obviously Zeitronix Zt-2!
No really, you need the wideband. It makes all the difference.

I know, I still have the display from my last Zt-2, just that money is shor right now due to the holidays...It's on my list:D

More logging today.. Good news, Dy noscan is going to try and incorporate knock detection in their new dynoscan version. They are going to send me a BETA of their new version to test it.. once we get the bugs worked out, Ill let you guys know.

more logging:

Does the program have a power/tq calculator?

Yes, But I have yet to get that dialed in right. It showed 435hp on a completely stock X :noidea:

It "computed" my final drive as 7.01:banghead:
