For those who don't have convenient access to 93 octane at the pump, here's an easy to use utility for calculating the appropriate mix ratio between 91 and higher octane fuel.

93 Octane Mixture Calculator: Calculate Gas Mix for 93 Octane

Use the Find 93 Octane Mixture Calculator to find out how much of a higher and lower octane gas you need to get 93.

Hi guy’s,
I fitted the jB4 to the I4 2.0 turbo this afternoon,
The fitting instructions are very vague and wrong!
Burger say that there are 4 screws to remove from the charge cooler to get to the sensor there’s actually 6.
BUT you do not need to remove any screws to get to the sensor harness, you will need a very bright light to see the location of the sensor plug and you will need to make some tools to enable the removal re fitting of the plug.
I bent a long screwdriver to a right angle and angle ground the tip to a point to enable the removal of the original sensor plug (see photos 1 & 2 ).
This tool enables easy disconnection of the plug.
Once disconnected its is impossible to re -plug in the JB4 sensor without fabricating another tool to enable the re connection of this plug (see photos 3 & 4 ).
I used a coat hanger bent to form a helping hand shape so i could offer it up to the socket and soft insert it, i then used my fabricated long pick to push the connector home with a satisfying click once fully home.
The job took 3 hours to complete from start to finish, i used ramps and worked off the floor.
Now i have completed the job and know the location of the sensor plug and which tools are needed i can safely say that i will be able to reciprocate and complete the job within 45 minuets.
I ran the car only around the block to see if everything was in order no CEL etc, i could tell immediately that’s there was a significant power gain, i was in tour running map 3.
Once i get the OBD 11 cable fitted (tomorrow) i will come back and write up my findings but i know i am in for some fun future driving !!!.
Cheers ALB

....and I wish I could buy you a beer!! Looking forward to your performance comments. It looks as if TDI instructions have you move ac compressor to get to that difficult sensor.

I met with another for member who has this installed. I’ve just read 30 pages of this thread and have a couple of questions.

I read somewhere that if you install the ODBii you get smoother performance and more features, what does that mean in reality?

MR69 are the intercooler bolts challenging to back out? Looking forward to impression/results, do you have a draggy performance meter?​

Posted in the install thread but here is the 93 map with ACN91 + Boostane Shot, Terry @ BMS gave it the OK based on logs.

It’s very pretty. Looks a bit like the Rockies. What’s its suppose to mean for us dummies? You def got my attention.

It means Terry at BMS thought I was safe to use the Map 2 meant for 93 octane fuel with the shitty gas we got in California + an octane booster. AFRs richen up as load and RPMs climb and then lean out as you let off the gas.

Ah yes, now I follow. So it looks like I’ll have to install the OBE reader once I get my kit..when fed ex decides to give it to me(sitting in it warehouse after one failed delivery last week). The wait is worse than waiting for my wife to deliver.

Will we be able to install headers now and will this JB4 tune help not throw any codes.
Is anyone going to do this mod and give us some feedback?

Don't think piggybacks work like that.

The V6 FE has a curb weight of approximately 3,267 lbs as per @Dragoon who weighed his stock on a race scale. The Eventuri is 1/2 lb lighter, and if you got the Aerie titanium exhaust, that's 18.25 lbs lighter than stock. So figure your car is roughly 19 lbs lighter, so a curb weight of 3,248. A relatively inexpensive way to pull another 30 lbs out of the car is to upgrade to an AntiGravity battery from @GRP. The 40ah is plenty powerful. That'll get you down to 3218 which is close to the 911's.

Are you going to connect your JB4 to the OBDII plug? It would be interesting to see what the numbers are with an Eventuri and the Ti exhaust.

I'm down to 3,253 lbs after installing my GRP intake and Titanium exhaust. Please note that all my weights are always measured with a full tank of fuel, and I also have a full PPF wrap. I didn't get to weigh my car before the PPF, and I've heard that PPF can weigh as much as 30 lbs, depending on the size of the vehicle and the thickness of PPF used. Perhaps someone can provide us with the weight of PPF on the Emira, so we can deduct that amount from my car for those who don't have PPF, but for all the other mods I've made.

A quick Grok search suggests that 8 mil PPF on a Porsche 911 would weigh approximately 10 lbs or less...

15.8 gallons of fuel at an average weight of 6.3 lbs per gallon would mean that a full tank of gas should weigh about 100 lbs in the Emira.
