My VE table is pretty jagged looking, but the truck runs really great, with minnimal KR that I'm tuning out. Does the VE table absolutely need to be smooth. I'm afraid to dial it up as I would sacrifice MPG............

 

My table jump up a good amount in spots when I did mine but I am actually getting better MPG now then I was and my table is smoothed out, but not sure if it would hurt anything.

 

I've never understood how it could cause mpg to drop, you are still in CL so the engine is pulling or adding fuel as needed, regardless of the v.e, especially if you are still using a maf. Now I could see in transit fueling but unless your tune is so far out the pcm can't compensate. I say SMOOOOOTH.

 

Yeah- I'm gonna smooth! I thought it thru, prolly shouldda done that first, and smoothing it is. The learning curve iw what's intimmidating.........

 

i hope you're using a w/b

 

Can't aford widebands just yet, life should be so easy. I'm doing the steps outlined in the sticky...................

 

Everytime I smoothed my VE table, it would make my WB read strange, escpecially at idle. When I did smooth my AFR would flucuate alot more, the last time I tuned my VE table I did not smooth it and it runs great.

 

No matter how much I smooth mine, every time I run auto VE tuning with the wideband it ends up all jagged again. I think I'm just gonna leave it jagged from now on.

 

I wouldn't really recommend using the stock 02's to get your VE dialed in. I started to tune a little based on the stockers and was quickly driven away because I was seeing some really weird commanded afr numbers and also pulse width wasn't where it shoulda been. I got mike's opinion on smoothing VE the other day and he really didn't comment much other than "if it makes good power and it runs fine, don't **** with it" lol. Just my .02

 

Yeah- if it ain't broke don't fix it. My IDC is great, really low- but then I don't wind the p!ss outta the truck- but I'll get a K.R. of about 1.6 now and then at around 1400 to 1600 RPM, which I'm still levelling off. Other than that I couldn't be happier with the truck really, at 7,000 feeet to boot...........
