ok i just did a run last night. also before the run i installed an easy performance fuel pump rewire and it didnt do any changes. im up for any suggestions. thanks in advance.

prolly out of injector or pump isn't moving enough juices

I didn't see where you logged or verified fuel pressure. You really got to do that.

i didnt get a chance to install a fuel pressure gauge during these runs as i was also going out for the evening. looking at the hp tuners scanner theres a ****-ton of various fuel pressure parameters, i dunno which ones to grab to and log

Unless you've set up the PID and put a pressure transducer on the fuel rails shrader valve, you really can't use any of them. You could look at and log STFTs and see if it's trying to add a bunch of fuel which would match the wideband showing lean.

I removed my o2s (passenger bung is capped off while the driver side is my WBo2) since I'm running OLMAF

If it just "suddenly" started doing this it's not in the tune.

I wasn't able to download your log/tune.

Can I ask why you are running OLMAF?

When is the last time you calibrated WBo2?

The wbo2 was calibrated after this started. I also got a new sensor and recalibrate it as well. It may be the fuel pump. I have a spare oem fuel pump somewhere that i may swap the one that's in the car (used walbro 255lph).

If nothing else get a mechanical gauge out of cowl and have a buddy watch it during a pull.


PS....OLMAF is awesome assuming you don't have big temp swings where you live. Done 800whp on OLMAF.

I can't open your HPT or HPL attachments either. I plumbed my Schrader valve into my no longer used EGR harness so I could monitor fuel pressure through the scanner. I verified my fuel pressure was dropping, and then noticed my voltage was dropping at high RPM. I was over driving my alternator shaft to a RPM that was too high. I rebuilt the alternator and switched to a slightly larger OD alternator pulley and that cured my woes.

If you haven't already, log the equivalent of HPT's "Control module voltage" PID in Torque ("Voltage(Control Module)[42]" is how it shows up for me) and see what it's doing in that RPM range.

My fuel pressure gauge hose needs replaced as i cut it for another project a while back. So ill have to get on that tomorrow at the parts store. I did swap fuel pumps but no luck.

is anyone able to open my hpt tune and/or logged run by chance? if not i'll try and reupload again?

also those running 42.5lb injectors, what are you guys seeing for your IPWs at WOT? I noticed mine's currently around 12ms and dropping to 11ms at top of RPM.

Why do you refuse to check fuel pressure and voltage? You have some smart guys here trying to help but you make it tough.

fst100

I'm not refusing, I just gotta fix the hose off the fuel pressure gauge and take another test drive lol. voltage I had already scanned and provided in my log file I uploaded in my previous post.

Since I cannot save or open the files you posted, what was the voltage range in the RPM range where you are running lean?

Please post a screenshot.

fst100

iTrader: (5)

Screenshot of what?

ddnspider

The voltage that you said is in the log that we all cant open Any other screen shots of the log showing the pertinent info may also help.

Will do. Doing it now. Gimme a few minutes.
