How do they accommodate this? Is there a specific map for 91, 92, 93 octane? Does AA dial back the 93 octane map for use with 92 octane? If so, what changes are made on the timing and boost side? I see on their website it shows about 18lbs of boost for 93 octane.

They lower boost, AA tune does not have access to timing

How much do they lower the boost for 92 octane relative to 93 octane?

Thats a questions better asked to Active directly.

[Math 440i]

I've the same question, but for 91 octane. I'm also wondering what are the numbers gains in HP/TQ on 91 vs 93. I don't have access to 93 here and I don't want to be disapointed with the results on 91.

I've tried to contact them via their website, but their contact page is broken...

Should be 1 psi or so lower, most likely on high RPM with mid range staying the same.
That being said, i recommend you give Active Autowerke a call at 305-233-9300 for an answer

They finally fixed their form. They claim 70+ whp and 80+ tq on 91 octane. If it's true, it's pretty impressive!

[340forJHV]

I just ordered my AA 91 octane tune on Tuesday. Should be here tomorrow and i'll post my impressions as soon as its installed.

What form? What 91 octane tune? I do not see this claim anywhere for 91 octane. What is the highest boost for 91 octane?
Is this tune box upgrade-able update-able?
Are 91 and 93 octanes are separate products or models of active 8?

[Roki187]

I have the AA tune on my car along with the ER downpipe and Bms intake and although there is a noticeable increase I highly doubt its 90/80 wheel tq. I was able to put the car on the rollers prior to the down pipe and tune, and it "supposedly" makes 320 hp and 340tq with a bms filter only. Auto x drive in 5th gear. So with their claimed 90 wheel tq I should be around 430 tq.....and adding a catless downpipe should yield another 20 wheel or so. No way does it make 450 wheel tq. My butt dyno says ~400 wheel tq maybe. Once the track opens I'll find out if those mods can get this fatty into the 11s

Don't get me wrong I really like the AA tune, just don't believe everything you read.

Also on colder days (50 and below) I'm hitting the fuel cap in the first 3 gears.

That being said... I have been able to gap a 16 camaro (modded), turbo e36 m3 and a 11 or so mustang also modded. Got my ass handed to me by a c7z but that's life

This is what the guy from AA told me yesterday by email. You can trust him or not... For the rest I don't know.

Anyway I've decided to keep it simple and to order a JB+ instead. The bang for the bucks and the installation/removal in 30 seconds makes it too good to pass.

Keep in mind the 90 ftlbs is in that lower RPM (around 3k) hump they put in the torque curve. Its ~50-60 ft lbs in the rest of the band. So it's on par with your calibrated butt dyno.

But that 90 ftlb hump is pretty awesome.

Below is a link to the product, with a spreadsheet outlining the HP/TQ gains:

I'm very happy with choosing the AA. Beyond actual numbers, they made a oem quality piece with massive usable tq gains. The car feels fantastic, escepially since temps are going above 50s. Can't wait to go to the track with some ms109. Really hoping for 11s.

Has anyone gotten CEL with this box running 91 octane and driving it hard at high RPM?

Using anything below 93 is not suggested. Their tune was designed for 93 pump (at least the one I bought) Why buy a tune from someone and go against their suggestion for proper operation. Octane is resistance to detonation.
Why risk it on a high compression boosted tuned car???

I had asked AA directly about the octane. They had been running the 93 octane map on a 91 octane car, with no noticeable issues (no timing pull, etc).

Where I am, 93 is almost impossible to find. I am at a bit higher elevation (3500') which is a lot different than sea level for power. Never seen any issues or CEL running 91. My only issue was it goes into torque limiting mode on the really cool days during WOT shifts. We don't get really hot weather here either.

[Roki187]

I had super knock situation happen twice since the AA tune, while in sport+ and moderate throttle. Engine malfunction warning came on with all the drama. Turning the 340 into a dead stick, until engine restart. Both events happen at low fuel level. And both times using bp gas (not the same stations) Most likely shit gas, I usually use shell only but had no choice at that time.

AA has been around for a while, I'm sure they have done extensive testing in every possible scenario and built in safety not to granate motors. I'm also pretty sure using 91 you will be ok BUT you will leave a lot on the table and knock will eventually happen. And although the dme will catch it and pull timing the more often it happens the more likely hood of potential part failure. Why spend $$ on a tune that's not being utilized.

The only issues I've ever had with my AA tune is if you use too much throttle or put it in sport/sport + prior to engine warm up. This can cause hesitation and CEL. Need to baby car for first 10-15 minutes or so of driving particularly when cold outside.

AA has not built in any safety measures to the tune, it has no method to do this as it's just tricking the car to run more boost. The car's ECU will be what prevents damage which is why you are going into limp mode. If you are going into limp mode with the AA unit and your car is fully warmed up, then you should turn down the dial on the tune as it's clearly causing issues at that level of boost. If your issue occurs because you are in sport + and car isn't warmed up, then wait 10-15 minutes before putting car in sport+ and don't go above 3k rpm until for the first 10-15 minutes either. Unfortunately no oil temp gauge, so hard to know exactly when warmed up, but this has been my general method after 2 years with tune on 235i.

I honestly didn't know AA relies on the dme solely for safety. I always let the car warm up prior to beating on it (340 comes with an oil temp btw)
And like I said it only happened when using certain bp stations and I should have known better.
And if it decides to granate sometime, that's ok. I have a warranty and also that's the price we pay sometimes. We all know the risks.

Also my buddy in his built evo9 filled up at the same station and threw a cel light for random misfire

Active Autowerke said that they were not aware of any B58 throwing a CEL so they should be told about this.

No need to freak out, like I said it was shitty gas during low ambient temps and moderate throttle. And has not occurred in 2300 miles or so. I also had a battery discharge warning, lamp malfunction warning and maf sensor fault since. All frequency 1 and do not return. Typical German maker drama. The cel light is part of Bmw annual maintance checklist.

If any AA related issues occur I will make them aware. No need to jump the gun.

Also before I trade this car I'll track it and dyno again and post the AA results.

[BMWILUVU]

Were these CEL cylinder misfires?
