Thanks
I see what you mean with the fuel trims but I am still unsure of what is going on? My wideband is reading way lean and my MAF EQ error is showing lean as well? Is it possible that my MAF...

Hi All
I pulled my box last week and C notched my frame for clearance. This required welding so I disconnected my battery and removed the gas tank for clearance. After putting...

Hi Guys,
I am trying to smooth out my tune a bit and have some inconsistent data in my logs. My LT+STFT vs MAF shows opposite rich to lean against my MAF EQ Error. I'm also getting some spark...

Disregard my last post. After spending some time I found a split silicone coupler. … I feel extra stupid.

So I was away on vacation for a few weeks now it seems like my tune is gone crazy. The lambda goes dead rich anytime I'm in PE? The last time I drove the truck when I was in PE it was perfect...

Thanks
How do I go about that is there a custom math I can do for that?

Thanks Greg
I did the transient changes you suggested and added a couple % to my VVE table from 100kpa up. I towed my car trailer with ATV and side by side on it about 300 miles on the weekend and...

I added a couple of different airflow readings and adjusted the ect mult values to .85. It looks a little better? what do you think? it still seems to be slightly lean sometimes? I also noticed alot...

I just got a chance to do some VVE tuning turn everything back on and do a log. It seems to cruise slightly lean on my wideband .99-1.03-4 while still pulling a bit of fuel on LTFTs? let me know...

Thats awesome Thanks
I will readjust my VVE and Maf tables and see how it works.

OK thanks,
I will go back to my previous settings in the meantime.

So I Adjusted my 02 to match what JBZ put in post 204 of the thread you sent me. I attached a new log. It appears to be worse and now my commanded EQ shows 1.02-1.03 sometimes? I am wondering if i...

Thanks
I adjusted my proportional gain down and will do a log to see if it is better. I Certainly dont want to burn up my trans LOL everything I read said to increase the bottom row on the virtual...

Thanks
I guess the problem is I don't know what the problem is with my 02? switching too slow or too fast? Also adjusting the PID control wont change that it doesnt match up with my wideband...

Thanks guys,
Holy that was quite the read. It is all very complicated but in the end I think I just need to lower my 02 proportional limit and possibly increase the closed loop integrator delay? I...

Sorry to repost twice in a row. If I change my Stoich AFR slightly to say 14.2 would that make my narrow bands stop pulling fuel though STFT and LTFTs and agree with what my wideband is reading?

My left bank still has factory 02 in near factory position and the right picks up both upstream of the turbo. The wideband is downstream of the turbo. Sorry for my ignorance but what do you mean by...

Thanks
I will try to calibrate my wideband and see if it makes the fuel trims and eq error closer.

Hi Guys
I have just finished my tune and was hoping someone could look it over to see if there are any obvious problems. I tuned the MAF VVE and trans using the bluecat tool. It seems to run pretty...

thanks 5FDP
I set the stioch to 14.3 in the zero column as I have the virtual sensor disabled. is that right? or do I need to do the whole table?
I also changed the PE and MAF settings to what you...

I have tuned my MAF and VVE tables then zeroed fuel trims and turned everything back on. The problem is now when Im logging EQ ratio error it appears to be slightly lean all the time and my fuel...

Every time I add to the Y axis in the VT table columns either airmass or map the tables change back to stock as soon as I leave the table and come back? It doesnt matter if I hit calculate torque...

This is from a few posts back. I increased the airmass on the VT table a few times and hit calculate but when I close them and go back they are back to original settings? my MAP tables only go to...

Hi Guys
looking at your attached pic your airmass goes up to 2500? did you adjust the max and recalculate? Mine only go to 800 making my torque max at 450. My spark seems to drop to near 0 degrees...

that is awesome much appreciated. thanks again
