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:

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:

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):

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 didn’t have room to wring it out thru 5th on each pull like I wanted, so I’ll do try to do that as I get tune revisions so we can see how things hold up as I’m 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.
