UPDATE: The weather allowed me to test drive the car again with the following changes: .028" IFR's to .031" IFR's [lean trasition circuit, 15-16+] 66 main jets to 65 main jets [60mph/65mph was in the mid to upper 13's] .071 IAB's [back to stock setting]
I started out after a short drive tuning the in D idle A/F ratio and I got it to 13.8-14.2 which made it idle nice at 850rpms. Then I started the test drive.
The following shows the last test drive (first) and todays results second. The 028" to 031" IFR's made a big difference (no more 16+'s) and they put me right about where I am guessing that I need to be for cruise.
Then I tested my WOT from a cruising 40mph to WOT and it showed 12.2 and then slowly climbed to 12.5 before it shifted into 3rd. Then I tested my WOT from a cruising 55mph to WOT and it showed 11.8 and then slowly climbed to 12.5 before it shifted into 3rd. I am guessing this rich WOT reading immediately at WOT kickdown, might be from my secondary pump cam combo which is a red/031. I am going to retest with a smaller cam, maybe the pink/031 to see if the number keeps from dipping down to the 11.8-12.0 mark. If this does not work then I will look at the secondary jetting. It is currently at 75. Is 13.6/13.8 too rich for 60/65mph? I could drop another main jet from 65's to 64's and retest. The outside temps are still fairly cool at 64 degrees today, so Summer may have me leaning it out anyway. I am surprised that my 60/65mph A/F ratio did not change since going from 66 to 65 main jets. I am wondering if I am still not on the main jets at these speeds. REF: My only 70mph test showed 3500rpms @ 13.6-13.8.
When I got back from my drive, the in D reading stayed at 14.0 and then I watched my N reading and it richened up to about 13.4 from when I initially left the garage when it was about 14.2. The car did not like the leaner N reading of 14.2 and it showed lean while driving until I got to stop and retune my in D A/F ratio as shown above.
