Working on my VE Table, I was going over my log this morning and when my AEM 300 series gauge is reading 1 lambda and matches commanded lambda of 1 or commanded 14.10 AFR in the ECM. If I switch my...

I did plan to touch on those areas around 2400-2800. Im not sure how bad that data is though, as it seems a lot of those areas lower on the map table are off throttle, or at least off and lightly...

Im at a point where my VE Table is really coming togeather and most of it is within 2% I need some advise from experienced tuners if you would touch anything on this portion of the ve table? Im...

Can someone please point out what adder is changing the EQ ratio between these two logs? None of the tutorials I have found touch on any of this. First one was this morning on my way to work and the...

Here's a copy of my log file. I just can not get it to read right, Both in the channel and histo. Histo's are kinda of a mess as I was just trying to get it to read right before I put in only the...

I have my WB running through a serial connection to my laptop. Would I still use WB Voltage or would I use a different parameter reading off my wideband? Im thinking about working around the hassle...

Think I've run into an issue with my EQ Error Math. My WB is running through serial connection and not the EGR or AC Switch. Only math I can seem to find refers to WB's hooked up to either of those....

Thats what I figured, but I wanted to be 100% sure I was correct. Thank you

Quick question, I've started tuning in Lambda. I have a good log with a Histo set up for Lambda Err. Do I treat it like tuning in AFR and Copy/Paste/Multiply by Half % into the VE table just like...

I bet this is the issue I am having, I thought maybe it had to do with a temperature multiplier somewhere because some days AF would be spot on. And on other days it would be off and my symptoms...

I've messed around with this table and my idle AFR is still always WAY off usually starts out fine until warm, I've even gone as far as to set that entire table to 1. Ill post a log and tune file as...

At work right now so I'm not able to go through my HP Tuners Software and do some digging, I noticed this morning that while in P at Idle before I left the house. my AFR was around 15.3-15.5AFR at...

Man, Cant wait till my logs look as consistent as yours. I am considering installing 4:10's with a Trutrac Helical LSD so I'm sure I'll have to revisit my table. I'm going to take a look at your...

Thank you for the tips, For lean cruise have you had a noticeable difference in fuel economy? Not really what I'm shooting for just asking out of curiosity. Ill get to working on my filters, By...

I just RTT'd, my tables at idle and that seemed to help get things moving in the right direction. Now I'm within 3% and I'm ok with that.

Couple of things, The 1600RPM cells are a little troublesome. Seems like minor changes cause that area to swing radically one way or another. Also, when you guys have areas like the 2400RPM cells in...

I do have an EQ Ratio set up, but its not reading correctly ATM. I'm pretty sure I have something off I just need to find it and correct it. I made the changes you recommended with the trans and the...

I have those saved for when I start doing some WOT tuning. Really trying to wrap my head around tuning in lambda right now as well. Copying AFR Err from the scanner and paste multiply by half in the...

Thanks for the fast reply, PE is not going to be set at that number. I actually just changed it before checking on this thread, going through the tune I noticed the numbers in the table were not...

I need some help with tuning on my 4L60E Trans in my 2000 Chevy Silverado 1500 5.3L 4x4. (Mods Posted Below)

1st
It seems all the information I can find on tuning the trans is vague at best or...

Copy that, ill change the logs to not log any MAF sensor data. I think I'm going to to set this up to possibly run STFT's only. Not sure yet as I've seen conflicting information and pros and cons for...

OK guys, I'm going batshit crazy trying to figure this issue out. Drives me nuts that I'm a ASE Master Tech and can build a professional IMSA Race Car but cant seem to get the hang of Tuning on my...

Awesome information man, I have never attempted to tune with the Narrowband O2's even down low and at idle like someone people say. It's why I dumped a decent amount of money on a good WB. I've...

I gotta question, for a street/strip applications with H/C/I mods do you guys disable LTFT's and just let STFT do their thing when you're done tuning? I've been reading conflicting information for...

Great Information, thank you.
