what are you trying to accomplish with a stock motor?

Emissions Defeat Devices No Longer a Top Priority for EPA (msn.com)

i looked at your file, seems if you just revert most those settings back to stock it should fix your issues

Just depends on what your needing to tune do one thing at a time, cruise control can be fixed just needed to make sure your air table was close enough before going any farther.
Make sure your...

try it

fuel trims are off alot, looks like your actually very rich which is probably why no power and running ruff. I can get you started in right direction but you'll need to do more logging and tuning...

Try this one should help but i dont know why anybody some things were changed i put alot back to stock settings to see whats going on.
definity read up on making better log file and make sure you...

shot in the dark with out a good log but see what this does for you

Well for my setup there are many reasons i need to do alot of things you wouldnt normally do on a simple cam swap

what are you trying to fix?

not the answer im looking for but more spark needs more fuel until you find the sweet spot
closed loop just up the temp so it never goes to closed on your o2s

May be a stupid question but does anyone know why when i disable pedal follower i idle very lean.

Running open loop i dont use closed

Pretty sure its running lean and seeing lots of knock on wot pulls, thats why spark is barley topping 7 degrees about 5200 5600 rpm and pratio and aircharge numbers look low
Just my 2 cents ...

im not getting kr at idle more in the 1600 to 2000 range and then some at 5600 and 6200 rpm
What im getting at is what would yall run your sensors at where its still safe to say no real knock is...

does anyone have a stock 6.1 log that i can kinda get an idea where to start?
I dont wanna guess at the number to harsh before i start desensitizing

No i wish i did but engine was no good had a spun bearing when i bought it

At what EOT does it stop seeing rock? What material are those forged outta? Who measured em and did the final hone? How much piston to wall did they say it has?








190

well im guessing its piston slap but dont know how because when i put them in bitches were tight as hell broke a ring on one piston trying to get them in so very tight tolerances. Had a Friend of...

Looking for some options on cold starts with these forged pistons with knock in low rpm range with out completely deadening knock sensors or waiting 15 minutes on warm up?

i know this is an old post but did you have any cold knock issues with those pistons and how you go about it if you did?

Response really doesnt look that bad, could always adjust it up little more...

power enrichment needs some work.....

Has anybody seen if your enrichment rate is to high it causes small lean spikes?

Looks like its going a little lean in 1300 1600 area even though 02's are picking it up yet, double check with wide band

Easy Fix guys but takes time to find correct settings for your car
Need to lower Minimum airflow and throttle body air flow first 3 lines only
if still bad then yes lower spark should be between...

That doesn't looks like correct tune that's pretty much stock settings
