2.3 off the corn and on the pump :D

Tell me what you all think.

Oh yeah, enable the PLX Wideband

Make a WOT pull from under 3,000rpm - over 5,000rpm and log it. I'm curious to see where your afr is under load and above 4000rpm.

If you scroll all the way to the right they did a pull to redline.

Why go from corn back to pump?

Availability.

Bought don't have E85 near me

Gonna guess you have a bad sensor or there's work that needs to be done in your VE map. DA table calls for 9.5:1, even more fuel is added in the fuel sliders. I'd say it needs some tuning.

Just said exactly the same thing in a PM.

That car should be running damn near pig rich with a safe tune.

 

[phunny]

Well it was tuned on his dyno so he probably went with his own WB. Might have to just get a new WB sensor.

Make sense. What a shame

 

[RvlutionMtrsprt]

I would suggest you call Lucas and just run it past him.

Was there any meth injected during that log? Thats a good amount of timing for a 2.3, I usually have to stay under 11* on 93.

No meth

I actually have a brand new wideband I almost gave away so I'll throw it in and see

 

[MY1GDSM]

I'm kind of confused who's tune is this? I don't know about anyone else But, the sheet above is too small to read for me.

Also are you on older firmware? looks that way to me. Either way hope those A/f ratio's aren't right...

Jeff bush from English racing tuned her. I'm think my wb sensor is on the fritz. I have another new one in the garage just need to install

1. Run through this. Either your TPS is way off (by the values, that's my guess), or there was no WOT pull in that log.

2. Why the heck did they add fuel all the way through 6k RPM's on those injectors???

3. Are you running speed density, but without an IAT sensor?

4. Have you done anything about the wideband?

5. Grab an idle log with the car warmed up and another 3rd gear pull from 3k to redline.

 

[phunny]

Here's the idle log, I'll try and get a 3rd gear pull later. I turned the key to on and cycled the throttle peddle and it does go to 100% and I still say that it's tuned for 13:1. There is a wideband in the piller and one in the bezal.

No log attached.

 

[phunny]

Fixed

 

[snowborder714]

Out of curiosity, go into the Direct Access section, reset OpenLoopThresholds to stock (click the black <----> double arrow icon at the top), and then save the changes. Then take another idle log.

Do you know if you have a factory front o2 sensor, or if it may be simulated?

FWIW, its locked in OpenLoop at Idle via the openloop throttle threshold... It has changes to SD table and MAF Comp sliders concurrently which...using sliders in general is really a no-no for SD operation, and has almost no changes to the OpenLoop tables... and has various changes throughout the Timing and Fuel sliders ...The settings really seem to be all over the place...a bit hard to decipher at first glance....

Not to mention with those settings and 2150cc injectors...i'm surprised it even runs on pump gas... it has to be rediculously rich...

We just so happen to live in the same town..... I'm going to meet up with him later this afternoon and see what we can figure out.

This crazy honestly. I'm not sure how things can be so messed up with Jeff's tune... But luckily dacowgod can save the day. Currently the alternator is crapped out so I'll be swapping it out this weekend and verifying the WB accuracy.

That fix is easy as checking the box in the MAFComp screen.
