Performance intercooler upgrade

[Thumbsy]

I'm driving a 2022 3.3L stinger with the JB4 installed but not connected just yet and also Injen CAI.
I really want to upgrade the intercooler but I'm getting bags of conflicting advice?? Some say that I will nee to reflash the ECU with suppliers saying that I do not have to reflash???
Would there be anybody who has already gone through this by installing and what did you have to do or were there any issues with the install?

All the JB4 really needs is updated/regapped plugs. Intake, exhaust, intercooler, etc are optional, and less important than higher octane.

Rule of thumb is map 1 for 91 octane, map 2 for 93 octane, then E30 for maps 3, 4, and maybe 5 depending on how your logs look.

There is absolutely no need to flash an ECU just for an intercooler change.
The JB4 can take care of almost any change you need. There's no need to *also* flash the ECU unless you're going E30 or E85 or trying to really push the limits.

an intercooler is simply going to make it a little better for the engine. No need at all to "tune" for that.
If that were the case you'd need a modified tune any time it got a little cooler outside.

Only reason would be if you didn't want to leave ANY power on the table and tune it right up to the gills.
Obviously not a great idea for a street vehilce that needs to be reliable.

Yeah i thought as much. I am running JB4 on Map 2 with Denso plugs. In Australia we have 98 Octane only in my baby.
I have Injen CAI and the motor loves it!

The USA measure fuel differently to Australia and Europe.

USA uses MON value at the bowser. It means Motor Octane Number.

Australia uses RON value at the bowser. It means Research Octane Number.

MON is more accurate in terms of guaranteed oxygen content in fuel.

RON is a slightly higher number than MON.

As a rule of thumb, MON 87 is equivalent to RON 91

MON 91 is equivalent to RON 95

MON 93 is equivalent to RON 98.

Well the post is mostly correct, the 91/93 octane in the US is an average between the higher stress/"real world" MON and low load/idealized RON, and is equivalent to the higher numbers you see in other countries which just use the latter:

right, just seemed like a random tangent since nobody is talking about what octane does or what scale it's measured on
has nothing really to do with whether or not one needs to tune for a better intercooler than stock unless other mods are coming along with it

Sooooo.....back to my question.
Do I need a reflash if I install a performance intercooler?

My JB4 is giving me plenty of grief so it has been disconnected until i hear back from Burger.
I installed correctly plug ins and fuel wires. My trouble is that the bluetooth is not handshaking with my app. If I start my girl without that it glugs and chugs and sounds really sick hence why it has been disconnected until I can solve the riddle of why it won't bluetooth connect.

In Diesel engines, Inter-coolers are standard because all diesels have turbo chargers. These aren't performance modifications. They are essential items to get any power out of a diesel.

It is simply charged air coming down the charged air pipe. and it needs to be cooled after it has been charged because the air expands when it is compressed so you want to cool it while it is compressed and you do that with the intercooler. The result is you can compress more air in the space you have.

Of course when you slap these turbo chargers onto petrol engines you have to also cool the air. How much difference it makes with a different intercooler I have no idea but I would have thought that Kia had worked it out already.....

I love these discussions about RONS and MONS and MODS.

At the end of the day it makers FA difference to the driving ability or competence of anyone out there. (Including me)

There about 1400 rules here in the legislation so when I ask someone what the ten roundabout rules are in Australia they gag at the only one they think they know then get it wrong. I also drove emergency vehicles extensively under a different set of rules.

"Give way to ALL vehicles that are (already) IN the roundabout and any tram APPROACHING a roundabout.

Are you a tram? No? Then I don't have to wait for you unless you are ALREADY in the roundabout.

It's pretty clear. Don't have to give way to your right......... It's both LEFT and RIGHT to the person who is there BEFORE you.

Don't come barrelling up TO the roundabout with your hand on the horn. It is not give way to the right. It is NOT a cross road. It is a ROUNDABOUT. Different rules.

Now, I could argue a yellow light all day. Yellow means STOP. That is it's PRIMARY meaning. Yet if you ask people. they will tell you it means uhm, ahh, gee, ah I know, if it is not RED keep going. Only stop if it is safe (cos it is never safe) cos the guy behind who never stops either will hit me in the back. It means STOP.

So I get it. We all want our cars to go that little bit faster than the next guy.

I'll have what he's on.

Not a BOT, but I did think it was a worthwhile contribution as a few people think 91 octane in the USA is the same as 91 octane in Australia.

Keep an eye on those Denso plugs. Mine only lasted ~5,000 miles before the tips had worn away completely. Just running Map2 on JB4. Sadly for me, the one plug I pulled to check early on looked just fine - all the others had already started eroding.
HKS I'm at 20,000 miles and aren't showing any wear.

I will type more slowly so that you can gather your thoughts when you read it again.......

When you compress the air.............the air heats up....................and it expands again.................so yes.....it expands whilst you are compressing it.......which is the opposite of what you are trying to achieve................so the CLUE is in the name............

INTERCOOLER

so what this does is this.....

the process is......

Expel the exhaust
drive the turbine
Compress the air
Air heats up again as it is compressed
Cool the air again through the INTERCOOLER (clue is in the name)
the air contracts again allowing more air to be forced into the engine
This allows MORE air to be compressed and repeat the cycle

Now that wasn't hard.....

you should probably know what you are talking about before a trash talking post like this.
I'll correct all your false statements for you.
First post, all diesels do not have turbos. Some are NA (I own one), some are turbo and some are supercharged. SOME turbo diesels have intercoolers, many do NOT as it is NOT necessary in a diesel because diesels are compression ignition engines so auto ignition is not an issue in diesels. Intercoolers do in fact help but are not standard on many diesels, particularly off road applications.

When air is compressed it heats up. No clue where you are going with the "it expands when it is compressed thing" as it does not. If you simply heated a volume of gas in a space that heat input would cause expansion. That does not apply when the heat is built solely from compression. (this is a property of gases and the same thing happens when you expand a gas with no heat input or output) The intercooler is then used to remove that heat as we all know, which does NOT then contract it as it would if you simply cooled a volume of air in a container, two different things.
I'm guessing maybe you think that because intercoolers always have some pressure drop from input to output but that is simply due to the inherent flow restriction of any heat exchanger. They're needed in gas forced induction engines simply because of the auto ignition problem with a hot intake charge.

Thanks for "typing slowly so I could gather my thoughts" but yeah, you should probably sit this one out.
