Ok so which is better?

theneelster

You don't need either until you upgrade the injectors and lower the pulley.

right i plan to be there soon, but which is better

BoostedYards86

When it comes to cooling mods on these cars you want to get as many as possible. Even on stock cars you will get alot faster in the 1/4

rnjmur

Without a tune you will not notice any difference on a stock car. You will reduce heat soak, but that will NOT help you gain better 1/4 times, just keep them consistant.

Once you go stage 2 or higher any cooling mods help reduce IAT and heat soak, which will help especially on consecutive hard runs or extended hard runs. Like I said before, if the IAT gets too high the car will reduce boost or pull timing. Even on a stage 2 or higher car you will not GAIN HP with cooling mods unless you are tuned for it, you will simply stop detonation and engine damage. But with the cooling mods you can get tuned and run more timing which will gain you HP.

go you. Now a header? The CEL will come on when you install this right?

rnjmur

If you are just installing a header you shouldn't get a CEL. If you install a downpipe with high flow cat or go catless then you will more then likely get a CEL.

wow, you might wanna tell this guy that hes doin it all wrong then

this is cool thread. I'm actually learning something. Subscribed

rnjmur

Seriously, did you even read ralliartist's thread or just stick the link in here because you felt like it?!

He is saying the same crap I just said - HE TUNED FOR THE COOLING MODS!!!!!

You didn't even quote the entire thing:

If you are going to try and make smartass comments at least read everything first.

an0malous

when another person runs rallis times, with only cooling mods, Ill believe it makes the difference that some of you think it does.

Ok,is there a way you can get rid of the cel? Cuz some cars they have antifoulers and that will get rid of the light. So when running a smaller pulley will I throw a code?

tubbs

in the begining all he did was **** with tq mangament, boost limits and raised the redline. he didn't "tune for cooling mods" and still had gains in the 1/4.

rnjmur

Messing with TQ management and boost limits can easily gain you time.. maybe even 1/10 of a second...

ok so is the reflash necessary? i mean like do you NEED to get it?

rnjmur

If you are changing injectors you MUST get a tune or flash. If you are doing cooling mods or swapping pulleys it isn't necessary to get a tune.

what a tune and a flash are basically the same thing? ok. so was there anythin to take the cell off wit the downpipe?

You can use HP Tuners to delete the code.

wouldnt the light come back on?

Doc

not if you turn it off (delete)

zackss

no

i've been running catless for about 3000 miles and i haven't seen it since i was tuned

Oh ok. thats the only way to clear codes? What is HP tuners?

rnjmur

You can clear codes by simply disconnecting the battery. If you want to DELETE a code you must use HPTuners to delete it.

A tune and flash are basically the same thing... normally a flash is a simple write done at a dealer. A tune is when you actually get HPTuners (or other tunign software) and make adjustments. Another option done by some vendors is to swap the actual PCM.

Doc

Oh ok i got you. Disconnecting the battery for like 5 mintues resets the ECU? But the code would come back on after it find it again right?

Question: Does this car have a Adaptive or Learning ECU?
