1980 Pontiac LeMans Station Wagon - G-T-faux (stuck with it, and can't shake it... like a bad case of herpes)

3. Hatch popper. Despite our best efforts Tatiana and I couldn't get it to release the glass. Without the glass it pops fine, with it no bueno. Either the battery was low or there is too much slack in the cable.

Verify that your getting battery voltage to the solenoid. I have had the push button go bad and not give full power.

Possibly plugged fuel filter? Easy stuff first.

Swapped the MAF settings back to the ones used at end-May and it resolved the WOT fueling issue. I am wondering if it was a corrupted file segment?

In other news the car shat the PS rear bumper filler out last night - found it (so brittle) dangling when I backed out of the garage. LMFAO. Guess this is the car's way of telling me to get on with changing them?

Doing WOT pulls with the cutouts open produces favourable results on so many levels. PE EQ ratio checks out - or about as good as you are going to get without Closed Loop correction with 130+*F IATs.

Only thing it needs now is more MPH commanded as it is shifting before redline (6700rpm) = more smiles per gallon.

Ummmmmm.....numbers.....lines.....uhhhhhh....numbers.....lines........

Say it with me: Deh-Ah-Teh-Ah. DA-TA. DATA.

([50119.238] - ((1/[50118.238]) / ([50118.238])) / 1.136) * 100)

([50119.238] - ((1/[50118.238]) / ([50118.238])) / 1.136) * 100)

So, does that mean?

So, does that mean?

Equivalence Ratio (WB02) Sensor in Lambda (reads from 0.50 to 1.50) SUBTRACTING Equivalence Ratio Commanded (1.0) DIVIDED BY Power Enrichment Equivalence Ratio (1.136) TIMES 100 = Error Percentage

Long story short it is the math equation I have been chasing for months to determine MAF and VE fueling errors under WOT. If you use the User Maths in HPTuners you'll understand. Next I am going to filter it for RPM above say... 3000 rpm. I am really excited.

Mike you might just have the baddest wagon on the planet however when it comes to technology.....well if it weren't for the invention of the carb my sh*t would run on coal and steem so how about a WOT sound bite! Oh yeah that I'll understand
