Burger Tuning JB4 for Kia Stinger!

[Never thought]

It should be OK but the only way to know how well it's working is to log it.

Got it. Sorry to keep asking questions. But if it was not running well, and I logged it, would you be able to get it working properly? I just don’t want to buy it and then be unable to use map 2.

If map2 is too strong for your fuel/car/conditions you'll use map1 or a custom map6 profile between map1 and map2.

I'm working that out now. I think 1200psi which is 8 in JB4 logs.

Can this be disabled or changed? My car dips into the 8s for split seconds on some runs right after shifts. Having the safety setting kicking in a little early would get annoying but I guess it’s there for safety.

 

[Terry@BMS]

Making it user adjustable just means endless questions on the subject. So we'll pick a good safety setting and roll with it at least initially. But it will be based on customer logs and what we think is and isn't safe for the car. Rather have a safety kick on and abort a run than not turn on and something gets damaged.

Sounds good you the man.

That sputter the car gets is that the same as leaning out or knocking? Or is the car just just sputtering because not enough fuel? I have a log I can post in map 5 where I got some sputter/missing in 3rd gear not sure if was from fuel pressure or what ever but if it would help you I can post it.

Another stupid question. What would be signs of map 2 not working correctly?

There are a couple Youtube videos on how to read your logs

ign1 (or ign2-6 as well) dropping as your RPMs are climbing, or sharp drops anywhere outside of shift points.

No, it's different than leaning out, and different than knocking. It's fuel pressure related sputter.

So is not something I’d necessarily hear or feel? I’d have to log it?

You would definitely feel it if you know what the car should feel like and what it shouldnt. If your on the fence you can check your logs.

@Terry@BMS should do a Log reading 101 video for everyone

There's already a really good write-up on n54tech about this: Logging Parameters and their Meaning - N54Tech.com - International Turbo Racing Discussion

It won't match up to our logs 100%, but it will give you 99% of the information you need to interpret logs properly.

 

[Adamdan]

The car would feel sluggish. I would run map 1 get some logs and post them. If map 1 logs look really good chances are map 2 will be ok. If you see any timing dips in map one will be a good indication how map 2 will go or if it’s even worth trying out.

How are you guys posting your logs on here?

Quick run from tonight as it's nice and cold, 45F! Car is on a half tank of E40 and I ran map2 (no WMI), car is on the stock rims/tires, has our prototype intercooler, and a new suspension modification we're testing.

Hauling ass for such low boost! Tried a run on map3 and was able to get high fuel pressure to start dropping so definitely time to get back to work on fueling upgrades.

I was thinking a parallel secondary pump setup like the fuel it E series pump with the modified hat and terminals. Ie this one
BMW E-Series FI-650HP LPFP Upgrade

Then use JB4 trigger to engage pump under higher boost. When you think you might have something like that? Does the fsb work to trigger it or do you need additional module?

I don’t know much about this stuff but I would love to see just a replacement fuel pump that’s stronger so nothing has to be modified and more wires run to jb4. I like the stealth upgrades. Dealer seeing more wiring going to the fuel pump prob not a good thing.

Limited options with 4 wire pumps and with straight replacement you have pressure regulation and fpcm current/temps to manage. Higher volume pumps usually draw alot more current, and can overheat the fpcm unless an aftermarket one is introduced. Meaning usually there is more wiring involved anyway. We don't need higher fuel volume and delivery at low boost. Stock pump fine for that. A parallel on demand pump commanded by JB4 is the most straight forward path in this I think.

If that’s the case I don’t think I’ll go down that route. I’m still hoping they can get a bit more flow out of the stock pump for people keeping stock turbos and only looking at a small improvement.

A second pump is the most likely scenario. Normally we can set it up so the factory EKP can control it, depending on how large we need to go up in pump size and how much additional current is drawn.
