Longtubes and existing lund tune

[therod785]

Will be installing longtubes soon. I have an existing lind tune from my bolt ons.


Will I need lund to retune and relog the car again. Or do I just tell them what I added and they send an update ?

Free flow exhaust ?

If they are catless, yes you will need a tune, oops forgot it is illegal to turn off the check engine light for missing rear O2 sensors.

Still will need the O2 sensor delay reset.

 

[therod785]

Yes catless.

I mean, will I need to do all the steps as before when I initially had them tune it ? Or they just send update for new mod ?

They should be able to send you an update. Depending on who your tuner is and how long you have had the tune, they may charge you.

I'm not a fan of "big box" tuners.

I have to use remote tuners. Nobody with mustangs trusts tuners in my area. Closest reputable dyno tuner is 5 hours away. :(

Basically it's about how it's up to YOU to fix the rear O2's.

I get it. I spent over 2 years learning the Ford tuning system due to "tuners" not listening to what I wanted out of the tune.

There are many smaller tuners who will remote tune and not lock it. The several I'm thinking about will normally have 4 or 5 revisions to dial in "your" car.
Not just say "yep it's good" and will work out problems if they arise.

This bullshit again. One more time. Cause it's proprietary. They spent a lot of money to purchase vehicles to R&D on. To get one of the best/safest vetted tunes anywhere. The 'smaller' guys, and lets be honest here, the larger ones too would gladly like to get there hands on it. Give it a 'degree' more timing, then claim there tunes are the better & there own. If anyone doesn't like it. Learn to tune your own shit like you did.

If i already have lund tune, can I also get a PBD tune on the same nguage?

Edit. Seems like catless is a headache I don't want to deal with. Will go catted instead.

No, Lund uses his own operating system, you are stuck with him.

Unless you buy another Nguage or MPVI2 or other devices.

Just get some midpipes with the rear o2 sensor bungs, o2 harness extensions, and use spark plug defoulers to get em out of the exhaust stream. No tune needed. Easy peasy.

Defend the lockers all you want. There is not any magic in a tune. I've seen Lund's tunes and they are the same as other tunes.

Maybe on new platforms, sure lock it. But once the encryption is known, it is just basic tuning.

They don't buy "cars" they buy PCM's, then they decrypt the software. Then they identify the tables to modify fuel and spark.

Once that info is out, they all do the same changes. It is, after all, a 4 stroke cycle spark-ignition internal combustion engine.

NO MAGIC!!

They don't ? M-kay buddy lol.

Probably should just stay stock headers.. I dont think it would be worth the cost or effort to put in catted longtubes, in my opinion. and usually aftermarket cats arent as robust as factory from what I've heard from multiple places and can sometimes melt, especially if boosted.
