Wideband wont run the number

[gnmaster2004]

I have the 6.1 chip with E-85 fuel. Target wot is set to 11.2, but at wot it goes to 8.0 full rich in all gears. Idle and cruise fuel seems normal.

Something is hooked up wrong most likely. Describe where you have every single wire connected from the wideband, and which exact wideband you have.

 

[gnmaster2004]

I have the X-series p/n 30-0300. I connected the solid white wire to the #1 port on the analog block,brown wire grounded to engine block, red wire to the fuse block ignition power, and black to engine ground. The rest of the wires are not connected.

Can you send me a log?

 

[gnmaster2004]

I would if I knew how

 

[EricM]

While you have powerlogger connected, if you hit the space bar, it will start recording. Hit space bar again and it stops recording. Then press the Save button and name the log. You can attach the log to an email, or upload it here.

here I think

 

[EricM]

Yes that worked. It looks like that was just a low rpm log though. I don't see any WOT in there.

The other reason it could be too rich at WOT is if the chip is set up expecting way more power or boost, and the correction can't remove enough fuel.

Here is a wot pass

Ok, that chip is set up for a mid/upper 10 second car on E85, so the fuel is set up for max duty cycle with those 80lb injectors.

If it's not making that kind of power, then you'll have to back the base WOT down quite a bit (param 4). The closed loop correction has hit the lower limit (-10%), so I would work the base WOT down. I would put it at 115, and make another run. You might have to keep going, but keep an eye on knock.

 

[gnmaster2004]

Thanks Eric, I will try that

 

[gnmaster2004]

Hey Eric, I brought the wot fuel all the way down to 99. Its still rich but better. its gets up to 11.2 even 11.4 its set to 11.2.,but it takes a while
