1st 398.8, 385.1 with 13.1:1. 2nd: 399.3, 387.9 ~13:1 A/F; a couple of questions :) Timing was ~22.4 on 1st pull.
First off: I changed programs this morning with Edit in order to lower cruising L-terms. Then I went to my exhaust guy and had him blow-torch the O2 Sensors.
Torque was very low with peak at ~4800(second numbers) <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />
Hp peaked at ~6K.
Initially I had the PE tables vs RPM adjusted for 8% more fuel at higher RPM's, 5% at lower rpm's and so on.
When I did the 1st pull, PE table was left stock. Injector Flow Rate decreased by 3%.
I forgot the hood was down for both pulls <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />
The second run I kept the Flow rate the same and multiplied my PE vs RPM table by 101% (should have did 105% I think).
I didn't give the 'puter enough learning miles since I changed the program this morning and the dyno-run this afternoon <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />
My question is: how can one dyno-tune in one visit if the PCM needs learning miles in between programs <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
Also: now that I was able to bring L-terms down by modifying the Injector Flow Rate table, would it be advisable to put my Ported MAF ends on instead of the stock de-screened MAF running now?
