Title: Help with some Power Logger files
Post by: quick72toy on November 29 2015, 02:36:35 PM

Need some help with some Powerlogger files. (I have this posted on the big board as well)
I have been having an issue with my AFR going rich, and then really lean when I get into boost.
It seemed to have started a short while after I upgraded the software in my Tpro to 5.27. Initially the upgrade went well, and was in the process of fine tuning, and then this lean glitch started happening.
I did a factory reset of the unit, and have been trying some different settings, but the problem remains.
I am running in SD mode, and I have made sure the ECM is in open loop.
FWIW If you are wondering about the boost spike, I'm running the BSTC and have it set pretty high normally, but with the weather getting quite cold here, I am having a problem with traction, so I am breaking the tires loose pretty easily.
Here are my current settings, and some PL runs.Let me know if you see any settings that should be changed.

Thanks,
Paul

Paul...check your battery voltage. I see it dropping as low as 12.2. It you're running out of fuel...mite that be causing your AF spikes? Is that boost spike of 25.6 I'm seeing real?

Title: Re: Help with some Power Logger files
Post by: Scoobum on November 29 2015, 05:23:49 PM

I'd recommend an in car FP gauge...or log it on PL. If all you have is an underhood gauge on the fuel rail...then you're asking for trouble. Making sure the charging system is up to snuff...and monitoring fuel pressure...is absolutely critical.

Yeah, I will be ordering a transducer shortly so I can log FP. Strange about the voltage. It's an Impala alternator built with HD parts. I'll have to check wiring as well.

Yup noticed that. Will do. Yeah. I normally run close to 24 lbs, so with the cold weather and traction issues, I get spikes like that. Also, low load in low gears. I also run the BSTC so I can turn it down on the fly.

Been through the voltage issues. I added a few grounds. One at the alternator bracket to the body and one at the fuel tank. Not sure about your vehicle though... I also checked voltage at the back of the alternator and at the fuel pump. Had about .4 volt drop at the tank which is about the norm for the length of wire run to the pump from the alternator. 13.8 at the alternator and 13.4/13.5 at the pump. Good luck!

Post by: quick72toy on May 28 2016, 10:10:24 PM

Hi, I'm bringing this back around because I never resolved the issue.
So, since my last post I have added a fuel pressure sensor, replaced the plugs, checked the coil pack, and had the alternator tested.
I have also reset all Tpro settings.
(They are under the attachment "Mine may 25 2016.bin") :rofl:
I have also included a couple of Powerlogger run files where you can see the AFR jump up when I get into it.
I am wondering If I have a setting wrong in the AFR tracking section, or if it is an overlap from the Part throttle/ cruise tracking section that is causing this issue?
For those that don't want to look at the bin for my settings...
Here are the AFR basic settings.
Min TPS 3.5
Min RPM 3200
Min Load 166.4
Gain 5.2
AFR 11.8 2000 to 5000 Rpm 11.5 after

Here are the PT Tracking settings
Idle TPS 0.500
Idle Rpm 1408
Idle A/F 13.5
Cruise TPS 1.840
Cruise Rpm 2560
Cruise Load 91.0
Cruise A/F 14.7
Lead Load 84.5
Lean Delay 10.0
Lean A/F 15.0
Gain 5.0
Enabl Dly 50

Tune high Load table is all 0%

Thanks.
Cheers,
Paul

Paul, I'm not seeing a WB reading...just NB. 770ish at WOT. If you're running Erics SD chip, I believe tracking is turned off below 9.0. Doubt I can be much help.

Just checked your sig...you're running MAFTPRO. I'm out.

Thanks anyway! WB is going from High 11's up to 17+ Yikes!

I would say you have a wb problem unless you are running a heated nb O2

Hmmm? I'll have to do a search and see if this is symptom of the LC1 WB?

Title: Re: Help with some Power Logger files
Post by: Steve Wood on May 29 2016, 11:55:00 AM

LC1....wonder you have made it this far. I went thru three of them before I gave up. They are the reason I run open loop most of the time even tho I now have a NGK that works all the time :) The last one is still new in the box around here someplace. I tried to give it to Yaklin for his Challenger but he sent it back and bought something else so I guess he did some research? lol

Ha ha! :-) I guess I have been one of the lucky ones. It has been good for a long time. I have been reading that many have had issues with them, (kinda says something if they send it back, and it's free LOL ) but I'm hoping because the rest of the readings (Idle, PT tracking, cruise) are good with it, that I have messed up a setting in the Tpro. Things are pointing to lowering my AFR Tracking TPS settings, because it doesn't take much throttle to get it into boost, and I am trying to be a bit careful by not fully mashing the gofast petal. Next I'll try playing with the gain level which is set pretty low. I'm also wondering if I have somehow corrupted my VE table? I have nothing in my Hi User Tune table to help.

If you need a new sensor Amazon shipped mine Monday & was here Friday for $80 all in!

I had the WB 02 sensor in my TBSS show very lean when it took a crap.

Just to throw this out there...Lets pretend that the WB O2 sensor isn't the issue, what would be the next thing you would look at?

Title: Re: Help with some Power Logger files
Post by: Steve Wood on May 30 2016, 12:20:20 AM

A bad factory version o2

Title: Re: Help with some Power Logger files
Post by: Scoobum on May 30 2016, 06:31:30 PM

Paul, the CC's and 02's should be moving at a good clip if the 02 sensor is up to snuff. If they're slow...then it's on it's way out. Mine were noticeably slower the week before I was at Armdrop. Use a Denso...they can take a fair amount of abuse.

Title: Re: Help with some Power Logger files
Post by: quick72toy on May 31 2016, 04:22:46 PM

Factory O2 looks good. Moving pretty quickly. Take a look at the PL file.

Can I get a part number on the Denso O2?

I have to laugh at this and give myself the Dumb Ass award for this. :icon_redface: After all this going over log files, and much resetting of my Tpro, I found the problem... I had a blown up a turbo to "y" wastgate hose!!! I was going to pull my narrow band O2 sensor to exchange it with another, and while I had my hands under the turbo I felt this piece of lone hose ??? ? WTF ( Yeah old hose. :rolleyes; ) Replaced the hose and all is good. Sure explains the wild boost spikes as well. Oh well, I will now have a spare wideband O2 sensor on the way, I ordered a few days ago. :rofl:
