Just installed ARH L/T headers w/cats on my 2013 F150 5.0L and also bought a JLT cold air that requires tuning and not sure where to begin to make changes any help would be appreciated. also attached latest tune13f150jr3raptorwheelswapaxleswap410-5-18-22.hpt Thanks
which JLT CAI did you purchase (110mm, 123mm)? as far headers go increase the O2 transport delay and O2 sensor time constant by 50% i would also increase Hego Tip Temp and adjust Hego multipliers
It is the 110mm ThanksOriginally Posted by mstang_man
I thought the F150's were SD and used a MAP sensor and do not have MAF. So why would the CAI need a tune?

if you multiply the Maf airflow period Airflow By 1.66 should get you close to JLT 110mm Maf data sheet.
Looking at his tune I see it has a MAF sensor.
Learn something everyday.
Thank you I'll give it a try

ECO BOOST do not Have a MAF per say they Have MAP instead
Gen 2 and 3 Coyote F150's use a MAP sensor and not a MAF. I wrongly assumed the Gen 1 didn't have MAF either.

mstang_man Thank you very much that actually got me really close and after just a few changes throughout the table believe I got it whipped and much appreciated.

Cool beans!!
Hopefully this works on uploading but these should be the latest datalog and tune I built for the JLT intake. I would appreciate any looks and advice. Truck runs good and seems good but don't want to hurt it if something seems off. Thanks a million for all the previous advice

Looking good so far, your fuel trims +/- 3-5% are you using a histogram to make changes? if so maybe 1 or 2 more revision if you want it perfect.
Thanks for taking a look mstang_man and yes I am using the histogram to make my changes. I thought the same thing but wanted to make sure I was on the right track. I'll try a couple more and see how that goes. Thanks again
