I know you said hemis are a little more difficult but i need a little guidance with my long tubes i know some modifications to the tune will help so far i just got the back sensors disabled
Thanks to your video i was able to make my O2s switch faster.. No more CEL for insufisient switching with long tube headers.. Thanks alot for sharing your knowledge with us noobs! Keep the videos coming!
For a 5.7 HEMI (ngc3) with long tube headers and catless. My car is running lean, i’m a learning with HPT. I want to ask what the better methods to correct the AF ratio? I need to correct the 02 like this and let the computer do the correction or be helped by AEM withband and correct the VE table? Thanks
My rear 02 sensors were eliminated when my cam and long tube headers were installed. Since then I keep getting a code saying the upstream 02 sensors inactive. Currently they read 440-450 mv regardless of rpm. My 30 year corvette guy that did the work says that it can be adjusted with the tune. Is that possible. All electrical connections are correct and I’ve went through 2 sets of new 02 sensors. Thanks a ton. 2002 corvette z06.
So I adjusted all these and she is running ok, although Im running just a little lean. Should I start tuning everything, or can I change one of these parameters and get it richer? I have no other mods, just long tubes, no cats and full 3" exhaust on a camaro ss.
Oxygen sensors don’t care what anything says they put your vehicle at 14.7:1 roughly so if you add to the maf and oxygen sensors and taking awhile fuel then your vehicle is too rich. You can’t get away from stoich The only thing you can do is put it in open loop mode and control fuel from pe table but that can be very difficult
@@Recklessmotorsports my problem is, seems like the o2 sensors are swinging happily, commanded AFR is 14.68, but the AEM x series reading about 15.2. I guess I could try a free air calibration.
I have my 2010 5.7 hemi charger long tubes & cats. The tune that I paid for disabled cats I went in and enabled them along with anything else needed to pass inspection for emissions. Problem I have is O2 sensor monitor and egr monitor will not run. Has a TSP stage 2 cam lost on how to get one of the last 2 monitor to run to be able to pass inspection.
So for gen 4s all that can be changed to address long tube headers are: proportional limit set to 1.25, airflow low-high reduce by .95 and if needed o2 readiness delay add “sum time”… ill try this and see if it works 😊
Keep them coming. When your trying to learn tuning every little Tidbit adds up in the long run. Thanks man!

Will this work with long tube headers no cats on my 2004 Tahoe 5.3?
Lmk
Same lol

Will these setting work with longtube headers and x pipe on a 2018 Camaro ss?
Let me know if you find something.. I'm doing 2016 camaro ss
I got my car tuned with long tube headers 2014 Camaro SS and still get lean to rich codes on both of the O2 sensors before the cats. Any suggestions?
Fix the tune
If you need a remote tune just let me know
@@Recklessmotorsports I don't know what that is. The guy who tuned my car won't respond back, so I am still running lean to rich.
You don’t have a tuning device at all?
@@Recklessmotorsports NO, just a code reader

It needs to be tuned so the o2 voltage will switch rich and lean
so can this be applied to all gen 3 and 4 with long tubes? and what about gen V is it similar ?
I don’t have those O2 options. Newest vcm editor. Having a hard time dialing in cam and longtubes
Hptuners doesn’t always map out everything unfortunately
Tried these adjustments on my gen3 not really affected the o2 performance…any updates?
If this is the o2 header video it’s just designed to be small changes for the o2 after header install to prevent codes related to o2 heater
@@Recklessmotorsports right I have issues with oscillation after coming to an idle. I ran across your video and hoped it would keep them bouncing.
Multiplying by .95 only lowers the value by 5%. If lowering it 95% you need to multiply by .05
So should it be reduced by 5 or 95, based on this correction
Same concept for hemi’s as well?
Yes
@@Recklessmotorsports thank you for the reply.
Will this work on a chevy tahoe 5.3L
I can’t see what video the comments are on what’s the title
@@Recklessmotorsports oxygen sensor settings artery installing longtubes. What gen 3 and gen 4 vehicle are you talking about in this video as well¿
07 Vette don't have Integral Delay...
Do you have anything on gen 5?
No videos but should be similar

You can adjust the MAF
@@Recklessmotorsports but my o2 sensors keep leaning it back out?

@@derBara83 i run into the same at idle. Cruising I bounce between 14.8 & 15.2 pretty consistantly. Shorty headers on my vortec 350/4L80E/4x4
Is this tune for 2017 camaro ss catless long tube headers, catback, and cai? Please help
Anyway you can make a video on turning off engine light after headers on 6 gen Camaro
Did you remove the catalityc converter?
Always
I did those setting and it change... Nothing at all
What video I can’t see

Codes turn off but monitors dont get ready with your settings
he doesn't reduce by .95.......he reduces by .05
miltiplying by .95 is NOT lowering my 95%. it's 5%. thank you for the video
