Just curious if anyone sees something out of whack. Recent engine rebuild, but just something just doesn't feel right. I'm sure it's in my tune because it ran better and pulled stronger until I upgraded my MS2.
I've used a combination of VE live and a previous VE and ignition table. Tonight I noticed after a quick run that the turbo housing was glowing like an orange and so was the #4 and to a lesser extent #2 runners.
I've covered most of the basics (timing verification with EDIS, etc.) I'm going to upload my MSQ and a recent data logs.
I'm going to see if I can list my mods in my sig.

Data logs... The last one I up the boost to 15 and added 3 degrees of timing from the 130-190 KPA section... That's made every damn thing glow. Too much timing?

Yeah, looking at your tune and logs not only am I not surprised it's glowing, I'd be pretty surprised if you haven't started pushing the headgasket towards the coolant ports as well. You've got WAY too much timing in certain areas, are dangerously lean under boost, your idle afr is all over the place (12's at some times, 17's at other times), and your fuel/ve table is a mess.

I attempted to mirror the ignition table I saw on here as a guide.. Key phrase being attempt. Can you point to any area of the ign map that I need to correct? Is it possible my LC-1 Wideband is not functioning properly? I think I will do a open air calibration on it just to make sure. I should have my wideband gauge tomorrow and see if it's close to what MS2 is reading via the wideband.
I started with a fairly rich table as I read on here, with the hope that VELive would lean it out...

It shouldn't be difficult to mirror the ignition table I have shown in the sticky thread here. Simply enter the numbers in your table so they match the picture. The main issue is where you added timing at boost onset. If you'd just run the table we show, you'll be fine.
No idea on the wideband, I can't tell you if yours is working properly or not.
Starting with a rich table is fine (though it appears VE live added a ton of fuel which means it wasn't lean after all). There is also instructions on how to manually adjust cells in conjunction with VE Live so you don't end up with a fuel map like yours where there are huge numbers in the middle and smaller ones all the way around.
Looking at how high your VE numbers are in the table (and it's still lean), either your wideband isn't configured properly in TunerStudio, or you've got some settings screwed up.
What MS system is this?

It shouldn't be difficult to mirror the ignition table I have shown in the sticky thread here. Simply enter the numbers in your table so they match the picture. That is what I initially did and it appeared to work good.. Even gave me that WOW feeling by throwing me back in the seat with only 12 lbs of boost. After the MS firmware upgrade, it's been fubar since. The main issue is where you added timing at boost onset. If you'd just run the table we show, you'll be fine. That last MSQ was me just pissing in the wind trying to make something work or F-ing break. I'll go back to the Ign Table I copied from here. No idea on the wideband, I can't tell you if yours is working properly or not. I'll go ahead and perform the open air calib, in addition to connecting my Innovative wide band gauge. Starting with a rich table is fine (though it appears VE live added a ton of fuel which means it wasn't lean after all). There is also instructions on how to manually adjust cells in conjunction with VE Live so you don't end up with a fuel map like yours where there are huge numbers in the middle and smaller ones all the way around. I read that and used it as a guide where the numbers went across up gradually in the boost areas. What you are now seeing is the results of VEL and yes it looks like dog $#!t. Looking at how high your VE numbers are in the table (and it's still lean), either your wideband isn't configured properly in TunerStudio, or you've got some settings screwed up. I'll double check the configurations and calibrate the wideband. What MS system is this? It was initially built by a guy of TurboFord that was 1st doing them... Not Bama and not Scott. Scott fixed the original one b/c it was jacked up and has been very helpful. All was good till the firmware, so it's quite possible I didn't copy a setting correctly. |

It appears so.
I'd take a real close look at the required fuel settings and the injector characteristics.

I have tried 2 squirts alternating and also simultaneous. It wants to run lean and even using Autotune and VE Analyzer, they are both pulling fuel, which isn't making sense. I double checked the AFR table and there are no areas calling for such lean conditions. I wish there was a way to undue the MS2 firmware upgrade, that's when my problems started. |

Are you positive your wideband is reading correctly? Did you re-configure your wideband settings after the firmware upgrade? How about your sensor configuration? TPS calibration? All of those items need to be set up after a firmware upgrade.
Misfires can cause the system to lean it out when it needs to opposite.

All of those items need to be set up after a firmware upgrade. Yes, I went thru the process of creating a new Profile, used the sensor config/tps/map, etc., as well as input that I'm using the LC1 wideband. The part I think might me screwing me after more reading is the PWM settings. I have it .850 right now.. It was at .650. That is what was suggested in the megatune manual based on larger low impedance injectors. Misfires can cause the system to lean it out when it needs to opposite. I installed new plugs yesterday and went with Motorcraft, per the required plugs needed. Should I run a colder plug and if so, what MC part number? I also double checked my wires (all new MC wires) and the ohm out properly (within specs). |

No, stock plugs are fine.
Can you answer the questions I asked (and you quoted) above?

I thought I did... Sorry bout that. Yes verified yet again that my sensors (Ford), TPS, MAP MX...6400 and LC1 Wideband are all calibrated accurately.
I settled in on the .700 Inj dead time and 2 squirts Simult, as that produded thye least amount of change.
Going to enter the VE/Ign Tables (again) that is posted on here, add 10 accross the board for the VE, pull some timing and go tuning to see where we are.

Sounds like a plan. Be sure to take some datalogs after tuning is getting pretty close.

;D I think I'm back on track or at least heading in the right direction... I've used VE Anal to assist me with the tuning vs Autotune! Run 100% better, no glowing header/turbo and AFR in the boost areas are 10's-11's. Didn't do any 3rd gear boost above 10psi's (last VE corrected table).
Laptop battery sucks! Went dead as I was going to make another datalog back to the house. Let me know if you agree I'm tracking correctly and any suggested changes are welcomed!
Attachment includes datalogs in order and current tune...
