Guys what is the best way to tune a 5.3/6.0 with bolt on's and a small cam not no bigger than a 228 or 230 duration?

I have Hp Tuners and the ngk wideband, What will make it easy to me to dial in a tune correctly? MAF open loop or close loop or Speed Density?

I'm looking to dial a good AFR on cruise and WOT mode.

 

MAF and VE as the easiest ways.

You'll be dealing with idle first anyway, then working on driving with it.

You'd still be targeting stoich for your fuel while crusing unless you wanted to run open loop and go leaner.

 

I would think the MAF will be fine here... you wont push its limits. You should get your VE table dialed in using a speed density tune, and then adjust the MAF tables when you re introduce it.

 

So tune VE on speed density, that means no o2 active. Then after finish active back the o2 and start tuning the MAF.

After all the tune will be finish and be in close loop?

 

Yes that's right. But I don't think it will be closer loop. I think you can still go into lean cruise etc.

 

Can I tune the VE with the STFT enable only? No MAF just STFT enable.

 

yes, thats how you tune VE without a wide band.

some say only use the wide band for WOT tuning (PE)


do all the fuel tuning before you tune spark

 

What about if I have the wideband on, and have the stft on?
I was looking trough a file and see that so I had all my VE to 0 to -3 and I turn that back on and the places were they were more off the went to -1 -2. Help a lot but just wondering if it's correct to use it.
