Could anyone give me an idea if i need an upgraded intercooler or not? I have a 14 228i tuned to bm3 stage 1, but really interested in the stage 2 and that is where it says i need an upgraded intercooler, does it really matters?

It's always recommended because increased boost = higher IAT's and an intercooler will help keep that down, especially if you do many pulls and/or live in a hot place. I'm stage 2 with a $200 G Plus intercooler from Amazon and it does the job well, drops my IAT's from 140 to 100 in the hot Florida summer

Upgrading the intercooler is a must on tuned cars. Since you are going with a stage 2, i recommend VRSF 6.5" competition, Wagner EVO II or CSF

Cool man!
I will definitely go looking for it!
Thank you so much for the suggestion!

Wagner EVO III

Thank you ZM2!

Alright, here are some logs on the first version of my E45 Jordan Tuned map. The map itself feels similar to OTS Stg 2 E30, so we'll amp it up in coming revisions. I'll limit my comments in this thread to just IATs.

In general, the Evo3 stays ~20F above ambient when rolling around town or just cruising, and ~25-35F if you're in traffic or stop & go. But, it drops to ~15F above ambient as soon as you accelerate or go WOT, and temps remain stable thru 5th gear. Examples:

https://www.bootmod3.net/log?id=5ee4...0b432aeba26ce8
https://www.bootmod3.net/log?id=5ee5...729b0f2d41897e

Here's a similar pull where I was in traffic before pulling out for clean air and doing a pull. Ambient/IAT delta starts at 35F, but drops to 19F thru 4th gear:

https://www.bootmod3.net/log?id=5ee5...90c61ca6d7fd52

And here are some back to back 3-4 pulls with hard braking in between. Ambient/IAT delta drops to 16F in the first 3-4 pull and increases to 26F after the 7th pull. This compares to a 50F ambient/IAT delta increase with my Evo2 in back to back pulls (second link):

https://www.bootmod3.net/log?id=5ee4...729b0ea9b3c476
https://www.bootmod3.net/log?id=5d72...90c6192c630438

Overall, it's interesting how this IC behaves. Ambient/IAT delta when driving normally isn't anything to write home about, but isn't bad either. But, when under load the Evo3's ability to shed heat and keep the ambient/IAT delta in check is pretty impressive, especially into 5th gear.

How it will perform on a hot track day is still an open question. Altho, from previous experience I can say that my method of back-to-back street pulls and hard braking are pretty taxing and just about as taxing (temp wise) as when I'm on track. As SeanWRT once said, my street logs highlight the excellent stopping power of my AP Racing BBK.


Lastly, I didnít have room to wring it out thru 5th on each pull like I wanted, so Iíll do try to do that as I get tune revisions so we can see how things hold up as Iím really taxing the car.

Either way, I'm pretty stoked about the Evo3 and what looks to be good WOT IAT management during back to back pulls from an IC that doesn't increase lag, doesn't weight 40lbs, and that mounts securely to the crash bumper.
