where is your wideband located? a few inches before the end of the downpipe i suppose? well i thought abt that but looking at the position of the bung its only a few inches further down.

 

No issues here. Did you cut the stock O2 wire where it goes into the ECU?

Google says you may have an exhaust leak as your problem btw.

 

ok i need a little input on this, i have set my open loop load #1 and 2 to 45 with 40 in the 3-3.5k range anybody have any ideas what i should run in the open loop throttle low and the open loop throttle high??? any input would be a big help i daily drive my car so gas prices on long island NY are ridiculous now

 

yeah i cut the o2 sensor wire to the ecu and connected there the narrowband simulator from zt2. i'll check for boos leaks and see.

 

Mine is actually behind my test pipe, halfway down the entire exhaust system. I will be moving it to the downpipe this summer to minimize the oppotunities for exhaust leaks BEFORE the wb sensor.


Open loop is triggered by whichever instance happens first. If your load is under 40 but your TPS voltage is over 3.01 volts, you will have triggered open loop. If your TPS voltage is 1 volt but your load is 50, you have triggered open loop. Its whatever comes first.

 

if you don't mind.. what is your narrowband simulator set to?

 

15.5afr

 

Same here - 15.5, gas prices are gonna push it higher though i think. 15.7 maybe 15.9.. We'll see.
I'm on E85 btw.

 

after i check my exhaust for leaks i'll try 15.5. as of now its set at 15.3. yeah gas is getting pretty expensive.

 

so wait, which is closer to WOT which is closer to 0% throttle like is 3.0v closer WOT or .15v

 

BUMP

I was thinking the other day , what about VV-T on IX's .
Wouldnt the LESS cam over-lap/cam timing = better MPG ?

What do you guys think ?

 

The higher the voltage, the closer to WOT. I believe its 5v at WOT.

 

JoT does this look like I could modify these settings to get the simulator to work off 15.5 instead of 14.7? I attached a screenshot from the LM Programmer program. Thanks.

 

Try setting the 1.0volt setting to an AFR of 14.88 and the 0.1volt setting to an AFR of 15.81. That should get you in the ballpark.

 

I posted my LM programmer settings in another thread ...

.80v @ 15.55
.10 @ 16.3

Those settings will put you in the 15.7 area.
