aFe Scorcher Install Review
After trying my hand at two different tuner boxes previously on the M235i, BMS N55 Stage 1 and Dinan Stage 1, I'm now trying the aFe Scorcher Module. It connects to the MAP and TMAP sensors only like the BMS box but unlike the BMS, the aFe has only the two connections on the harness. The BMS box has additional connectors that are not used on the M235i and have to be stored out of the way.
I went with the Scorcher for its straight forward design of connections, nicely insulated harness, and small control box. Installation was straight forward with only the two connections needed requiring the engine cover removal along with disconnection of the negative battery terminal in the trunk. Verification you have put the connections on correctly are nearly idiot proof with a blue LED light on the control box that will illuminate when made properly. A little gimmic like, but hey they are selling to BMW owners Single test drive so far and the torque delivery is very strong. Without having an actual Dyno numbers yet to show, it did break traction much easier and faster in Sport + mode. During my limited ride in manual Sport + doing 2-->3-->4 shift under full throttle I heard a change in the exhaust sound. I have the M Performance muffler and as we have seen in the videos and experience ourselves shift sound like short farts (lack of better way to describe them). With the aFe Scorcher the shift sound was louder and longer in duration. Had to do it a few times to verify it wasn't a fluke. What was a fart now sounds like a explosion out the exhaust pipes. More driving impressions needed, but it will make small children jump off the sidewalks and into the grass when it happens. This was my first initial impression. Was lucky to score this one from EBAY for $312 (used - like new condition). aFe is running a intake/tune combo special on their site for the same setup I have (Momentum Intake and Scorcher Module) for $734 which is good deal for both items.

I was thinking of running their intake and tune combo along with the Tuningwerk's exhaust I have coming. Leaving stock cats though both for warranty and CA emmissions... no downpipes for me

Definitely following this thread! More interested in this tune than any other, mostly because I want to stay conservative/safe, and it's a great deal with the exact intake I wanted. Any updates/insight will be greatly appreciated. Thanks in advance.

It's based on the same analog technology as the BMS Stage1, only instead of being set to 3.5psi as the Stage1 is, they set it to 4.5psi. BMS prefers to have CAN bus access in place for the higher boost levels so keeps those for JB4 level performance.
FWIW awhile ago BMS added the DB9 port back to their Stage1 tune so technically it can be adjusted from 0-6psi using the Stage1 interface and USB cable. So to match it up with the AFE set it to 4.5. The better solution though is to add the extra wires and JB4 box at that point. The rest of the connections on the harness are meant for upgrading to the JB4. The idea is you just swap the box out for $150, connect the extra wires in the harness, and have a full JB4. Mike |

When you say they use 4.5 as opposed to 3.5psi, is that the amount of boost over stock? Would you say that 4.5 is still totally safe for the engine without any other mods? |

Thanks Mike for the additional info. The BMS N55 Stage 1 kit is nice if you plan to upgrade to the Stage 2 (Full JB4). I have no intention of going that route and having just the 2 required connections makes it a bit cleaner under the hood. For those looking at getting the aFe intake also the combo deal could save them some good money as well.

Very cool Delnari! Are you planning to do a dyno run?
As you said, if you plan on getting the aFe Momentum intake, then the package deal is a very good deal ($700 on eBay) and the intake alone is $415 on Amazon so you're getting the Scorcher module for $285, doesn't seem like a bad deal at all, depending on results of course.

Looks like tons of spikes and the flat spot from the 2nd quadrant to the 4th in HP and the drop in torque at the same time |

Where did you find that dyno chart? The one I saw on the website looks like this (aFe module + aFe intake), though it's for the 335i N55 engine, they don't show the Scorcher for the M235i though Delnari confirmed with them it's the same.

Mike can you clarify/walk me through programming a stage 1 to 4.5 psi. I have a stage 1. Do I need BMs USB cable and laptop for this? I have 93 octane in my state so I would think a bump to 4.5 is safe for me

Nice information again Delnari, the scorcher does sound interesting. I ended up going the JB4 route after nixing Dinan thanks to your other thread. Mike has also been very helpful.
Just arrived Today
