Does anyone know the advantages/disadvantages of having the Cat warm-up DELETE ? Thanks!

 

it won't be loud as **** and wake up your 8 month old son every morning. Ask me how i know lol

 

I would consider getting a Trifecta tune JUST for that feature and then re-tune it myself...**** my car is loud on warmup

 

I like the raunchy sound she makes in the morning , like a sweaty pig given birth .

 

hahaha ya, that's never a good thing!

Well I have a Trifecta tune and cable, so I just got a new tune file with the cat warm-up delete on it and I wanted to make sure exactly what I was putting on before I installed it on the car.

Now that's a good description of what it sounds like! I think it sounds pretty badass myself, but it is excessively loud on cold starts.

If there are no real advantages other than the fact that it's quiet during startup, I may not load the new tune, or maybe I will try it out to see if I like it or not. Thanks for the input guys.

 

cat warmup is the reason why i put my stock DP back on. If you have to leave at 6:30-7 in the morning and you have neighbors all around you, catless DP with little muffling and cat-warmup is horrible. I used to put the silencer in my megan racing everymorning, start the car, then take it out before i left. what a pain getting those little screws and nuts on by hand at 630 in the morning in the winter when its 4* out

 

Well I sold my stock DP, so that's not an option for me. I have a Catted DP and a muffler so it's not too loud, but it's loud enough. I guess I don't really have to load the new tune then if it's only purpose is to quiet the car during cold startup.

 

just blip your thorttle

 

its not just for cat warm up...its also for engine warm up. thats why it maintains the higher idle until your coolant reaches a specific temperature, not the cat converter.

 

Good question.. I wonder if you delete it if it hurts the car in any way. Hell i just drive it right when i get in and dont wait for it to warm up at all. Seems like it's pointless. But it would be good to know for sure. I might delete it

 

It CAN be removed with HP Tuners as well...

 

This.

 

... Kinda

 

working a cold engine causes it to wear faster. The OEM has an increased idle speed to help it warm up faster and prevent as much driving as possible from occurring when the engine is cold.

 

I don't miss the MMMMBBBBBBBHHHHHHHHHAAAAAAAAAAAAAAAAAAAAAAAAAAAAA sound every time I start my car in the morning.

 

I have ******* neighbors so I love the sound of mine in the morning

I dont think the neighbors do but like I said they're ******** so F*** them

 

+1 and I have the stock catback. Almost everyone looks at my car funny when it's cold started.
Sure you can blip the throttle after about 5 seconds but it's still loud until you do so. I don't mind waiting a 60-90 seconds for the car to warm up a bit, just hate that it sounds like I'm getting ready to launch down the quarter mile under mild boost.

 

me to

 

yeah i definately am going to love not hearing how loud my car is in the morning

 

If I had a dollar for every time someone asked "What's wrong with your car?"...

 

lol nothings better then when i had to work at rt66 at 530 on a weekend lol........joliet is like an hour from me so i had to leave at around 415 430ish. yeah starting my car woke up numerous people lol!!!!!!!

 

No, you can eliminate almost all of that noise. And Im not talking about the ECT table thing either.

 

I like the warm-up cycle

 

Ha Ha, unfortunately , I have a " **** Them " neighbor on both sides...I want to move !

 

I just reply "It's just a Cobalt, wanna run 'em?"


People that know me say, Yeah, JUST a Cobalt!
