Burger Tuning JB4 for Kia Stinger!

[StungBlueGT2]

Ok- i was daring and tried map3 yesterday with only Oct 93 from Costco. No adverse effects or pinging and car runs like a charm. I heard boostane is not great to run everyday as it can be corrosive.

It may run ok but unlikely your getting full map3 boost without the ecu pulling the timing since 93 isn’t enough octane. Someone did a thorough test comparing logs showing ignition timing was always pulled and didn’t run flat or progressive timing until 96+ octane was used. Post some logs of WOT runs with map3 & 93 to see what ign 1-6 are doing to be sure.

Made an interesting Stinger discovery today. Cutting the brake signal wire to the ECU lets you power brake the car and do awesome burn outs.

So far no negative effects noted other than start/stop not working! Exploring the option to have the JB4 intermittently cut the signal off the signal once we have a better feeling for the effects and whether it allows the AWD cars to launch harder.

If anyone is interested in helping test it out email me! Requires cutting 1 ECU wire which you can splice back together later, so definitely for the more advanced crowd who understands what is involved.

Awesome and is this similar to disabling the brake switch like Tonka & others did?

BMS JB4 Stinger water/meth (WMI) sneak peak
Looks like they just temporarily disable it using a magnet so you don’t completely lose Start/Stop & Reverse. Still a temporary solution and would be awesome if it could be integrated into the JB4 with settings to enable it as needed.

Exactly. The ECU is smart enough to pull timings to prevent knock from happening, so you can use the map without risk but it will be slow.

Hey guys. I am assisting a friend install his BMS kit.

Question.
What setting should be in the app for the additives value when using boost juice?

Depends on many things.

We have a 1 gal tank.

Hey Stan. If you haven’t already check the last page on this pdf. https://www.n54tech.com/flash_files/stinger_wmi_install.pdf

It isn’t directly related to boost juice or the concentration of meth vs water, but it says use 50 additive to start with. That is about the equivalent of map5 which should be 5-7psi target. It’s still a lot of extra boost but should be ok with ~50/50 mix. Once everything runs well and logs look good you can try a higher setting and know some people run 75+ with no issues, but likely using 80/20 mix.

No not really. Unplugging the brake cable itself will have a lot of side effects (like, not being able to shift in to reverse). This just stops the ECU from intervening when brake boosting or doing burn outs with none of the side effects.

80 is water?

Oh ok and I may be mistaken. I must not have understood what Tonkas magnet trick was doing. I thought it was simply holding the brake switch sensor in a way that the ecu didn’t know the brake was being pressed. He made it sound like it was different than pulling the brake fuse or unplugging the cable itself so it avoided those side effects too.

80 is water?

Sorry for not clarifying but no. More meth would be needed for running even more boost effectively. So 80% meth and 20% water to run the highest “boost additive” settings.

I usually increase the water when I increase the boost.

Did I just read that someone was “daring” and tried map 3 with 93 only? And said it’s ok because they got no audible pinging? Yet, they have no logs.

It’s not even my car and I’m triggered.



Terry does all this extensive testing, advises us on which maps to use with which fuel and why. And yet we still have people doing their own thing and labeling that as daring. “Daring” isn’t quite the word I would use to describe ignoring recommendations.



But hey, it isn’t my car.

TRUE DAT.

Terry has never said not to use Map 3 with 93 octane.

The guidelines posted on n54tech specifically state "Suggested for high quality fuel including unleaded race gas, ethanol mixtures up to 30%, or high quality octane booster like Torco or Boostane."

Terry has actually written right here on this forum that high quality 93 octane can work with Map 3. And there have been forum members that have done so without issue.

I agree with this. Depending on the car and test conditions, the results can be different. Just try it and see the logs.

You might want to read my post again and try finding where I said Terry said NOT to use 93 on map 3. I’m sure you’ll have a difficult time finding it.

I stated that the recommendation did not say 93 on Map 3. The recommendation says the following for Map 2, “Map 2: 5psi over stock tapering to 4psi at high RPM. Suggested for 93+ octane fuel.”

To call 93 a “high quality” fuel to justify its use with Map 3 is a stretch and highly dependent on the quality of 93.

And your post further proves the point I made, which is people taking things into their own hands and running with it ignoring the recommendations. Absent any logging or data, blindly running 93 on Map 3 because others have done it is reckless. The italicized qualifier that you used of can proves exactly this point.

If 93 was a-okay to run with Map 3 across the board, the recommendation would say so. But in an effort to be conservative (i.e., safe) Terry did not mention it for Map 3.

Given how different locales have differing fuel qualities in addition to the blends for various times of the year, it’s not a recommendation he included, and for good reason. What may be good for some may not be good for all.

I stand by my statement, absent any logging for the particular user referenced, running 93 on Map 3 is foolish.

 

[xot1]

Are you using map 2?

 

[ecko04]

Are you using map 2?

Me? Depends on what I have in the tank. If I have 93, which means I had to fill up away from home yes — I’m running Map 2. If I’m around the house then I’m running E30 and I’m using Map 3 or Map 5. All of which I’ve logged at the stations I frequent in addition to a fuel test kit so I know exactly what I have.

Yep, logging is of most importance. Terry realizes the reality that in certain situations it will work as intended, which is why he's never ruled 93 & Map3 out.
