What JB4 Map do you DD

[monusa]

have been running map3, hks plugs and had no issues until..........sitting at stop light and noticed 'putt-putt" coming from exhaust. limped home after dropping to map0 and CEL lit up. read code and showed misfire cylinder 3. called an engine guy and he asked had i change fuel grade and i always run 93 octane. filled my tank the previous day and he asked if the station's tanks were being filled that day and just so happened they were.....water settles in the main tanks and he said i may have gotten some in my tank. since map3 is funny about the octane level, i swapped the plugs and added a bottle of "heet" and ran the tank dry before re-filling. now running map2 with no issues.......moral of the story, be wary of the higher maps if you can't verify the quality of fuel in the tank.....

Can you run stock plugs on map 1?

Why? Looking for problems down the road? Concerned about the install? Don’t say because you’re being thrifty, your car will hate you if that’s the case. What does Burger say about plugs? Change them!!

Well you’re an honest sort. Which is nice in today’s world. However you are going to be missing out on a whole bunch of personal satisfaction and a cold beer or two on completion.

Lazy or not.....Change the plugs!!!! and if you take your time to get them changed, then don't run jb4 above MAP 1. just to be on the safe side, leave the jb4 in the box until the plugs are changed. i was "antsy" as well to get that thing hooked up and going but in my case, the HKS plugs make all the difference in the world!!! safe yourself some headache as well with major engine issues!!!!1

 

[monusa]

Meant to say in my previous response, "....but in my case, i have the 2.0T and the plugs took about 15 mins to change(not including gapping, which should be done also)". The 3.3T is not so simple.....but change them anyway....

Map 3 with 93 and the mods I have, Map 5 with I drop in 4oz of Boostaine to a full tank of 93. Had problems with E30 kept getting CEL for low octane

Do you have any mods? I'm using 94 on Map2, planning adding 6 oz of BOOSTane to the tank to get on Map3... you're making me wonder if I could actually try Map4 !? Edit: HKS plugs gapped at 0.23.

I do have to say though, I did try Map3 one night with 94+1.7 (theoretical), didn't seem to have any issues.

On the newer firmware (because the maps changed from older firmware to new) I have 93 + 4oz boostane (which I was told 4oz was the correct amount) and run Map 3 without issues otherwise I just use Map 2

Map guide as of v15+ firmware (selected via JB4 Mobile/laptop interface. Map1 is the default map)

Map 0: JB4 disabled
Map 1: 4psi over stock peak tapering to 2.5psi at high RPM. Default performance map suitable for all 91+ octane fuels.
Map 2: 5psi over stock tapering to 4psi at high RPM. Suggested for 93+ octane fuel.
Map 3: 6psi stock tapering to 5psi at high RPM. Suggested for high quality fuel including unleaded race gas, ethanol mixtures up to 30%, or high quality octane booster like Torco or Boostane.
Map 4: Up to 7psi over stock. For use with unleaded race fuel and/or E85 mixtures up to 30%.
Map 5: Up to 7psi over stock but without top end taper. For unleaded race fuel use and bolt on modifications. May not be suitable for E85 mixtures due to high fuel pressure dropping. If using this map on E85 you should be experienced at reading your own logs and evaluating ignition advance and fuel pressure.
Map 6: User adjustable map. Enter value of boost over stock by RPM on user adjustment page.
Map 7: Progressive WMI (water/meth) map. Increases boost as a function of methanol flow & methanol boost additive. Holds boost low until WMI is flowing to avoid tip-in knock, and reduces boost as a function of WMI flow in the event of interruption like running out of fluid, leak, or component failure.
Map 8: Valet map, runs around half as much boost as stock.

Be carefull Canada 94 octane gas is often not that good and sometime Shell 91 outperform it. Make sure you always log before using for extended period.

Thanks. Indeed, I always add a bit of Octane to it to make sure. But now that I have BOOSTane in, I will try to go Shell V-Power 91+4, from what I've seen with PC94 it should be able to handle Map2 & 3. I could add more BOOSTane, but I don't want to go nuts, at one point the cost just isn't worth the extra power (besides I find Map2 to be very satisfying already lol)

 

[El_SadBoi]

I daily map 2. Looking at the results...why would anyone daily map 8...lmao

 

[turboAWD]

Map 8 used to be a different map - they were re-organized about a year ago.. Map 4 or 5 used to be valet, etc.. I think map3 now was map8 then..

I see...still makes me giggle though.

FYI - I watched a recent video from a guy in Vancouver and Shell 91 was compared against a number of other companies and was absolutely terrible. Ignition retard on all cylinders on a stock Audi S4 resulting in a 40hp loss.

Shell was terrible or all other companies compared to? Usually Shell is good and pretty reliable. Petro Canada seem to vary quite a bit. I have had good result with Petro Canada in the past but also got a few bad tanks that made my car run very bad. Sad the the station quality control is not transparent showing the current measurement of water content etc. I am sure many are not up to the standard and still sell the gas...

Canadian tire 91 has been the most reliable for me to safely run map2

You’re using crap Chevron 94 or some other crap CDN 94. Not in your best interest to go above Map2. You’re better off switching to Shell V91 and stay on Map2. Look at your logs or have someone look at them for you. You’re playing a potentially expensive game on Map3. If you have bags of $$ or don’t care please disregard my comments.

Rather aggressive assumptions there, but thanks for the tips.

I'm using Petro-Canada 94 here in Montreal, Quebec, Canada -- and it's been known that the PC94 fuel is of higher quality on the east than it is in western Canada. I also add 6oz of BOOSTane to each of my tanks which theoretically adds 4 points. I've been "testing" Map3 and so far it seems like I have no knock according to the logs. It's worth mentioning that BOOSTane also stabilizes the ethanol "negatives", so for what it's worth it looks like I am indeed left with some quality high-octane fuel for my engine at the end of the day.

Also, been following the V-Power 91 / PC94 debate for quite some time, and while I know that Shell's fuel is a Top-Tier gas here, there's quite a good share of people reporting that they were fine with PC94 and had knock with Shell's 91. To each their own. For what it's worth I intend to try both, I'm not married to a brand, if anything Shell's 91 would cost me less down the road, so I DO hope it works well & I'll gladly shift to it. But nothing negative to report on PC94 for me here so far.

Excellent reply. Sounds like you have a good handle on it. Not sure if we have PC94 don’t recall seeing it but will have a closer look. I’m stuck with V91 unless I do an E30. mix. I’ve tried the Chevron 94 and got ping. Are you getting your Boostane in Canada? If so where pls.
