Burger Tuning JB4 for Kia Stinger!

[Sabz]

Quick question... if not interested in the extra gains the fuel wires provide are they worth getting ? Is it better for the engine to adjust the AfR using the wires? Unless it makes running the jb4 safer then I’m not interested.. don’t care about the extra power..

Without the wires I think your car would just run a little richer, meaning your exhaust tips / back bumper might get dirtier.

That was before we did the inlets which opened up a lot more, on the N54 engine inlets + intake can add as much as 75whp at redline. But as I said every platform is unique. We make intakes for some cars that struggle to add 5hp. It just turns out the Stinger intake presents a moderate restriction.

I dont want to hear that.

Maybe im hard of reading... Are you saying new inlets and intakes filters have added 75 WHP on Bimmers...... If so how long does the NOS coating on the inlet piping last for? lol JK Thats pretty impressive for the BMW market.

Has anyone ever done actual airflow comparisons between stock intakes and their intakes? Id love to see who can get the most air in based on design or is it pretty much all the same either it be front mounted CAI, Short Rams, etc.

Not to make it safer. The fuel wires are used to adjust the AFR from 10.0:1 to around 11.5:1 in higher gears, which adds more power, and allow higher boost levels and E85 use without missing. But they are optional and technically higher risk than not having them. It just depends on your specific performance needs.

This used to be a thing in other cars I've had - you could log the MAF sensor and see how many grams of air per second is flowing. It was clearly beneficial to change intakes or modify the stock airbox when you could clearly see airflow go from 250g/s to 300g/s for example.

Right. I would love to see some of the OEM of the intakes start doing this. I wonder if a generic logger can do this for us.

I don't think the Stingers have MAF sensors. It uses speed density for air calculations

Thanks! Exactly what I wanted to know

@Terry@BMS

I was looking at the dyno charts on your site, and need some clarification.

Map 2 w/ Fuel Control: 391hp / 469tq
Map 2 w/ Intake: 416hp / 514tq

How does the Intake give gains of 25hp / 45tq?

These are nice numbers!
Which intake are we talking about?

BMS’s own intakes they will release in the near future.

Looks to use the stock lower half... I actually toyed around with that on my “homebrew” set-up.

For v7 firmware working on a cool new double-PID fuel control algorithm, nice improvement in AFR control over the single offset algorithm we're using now. Will recruit a few testers in the coming days.

So we're speaking French now?

He's using multiple parameters from the ECU (and a new calculation) to calculate target air / fuel ratios instead of the existing method which is using a single parameter. I think. Lol.

Yes I guess the direct English translation is "better fuel control". Thought the techies among us might be interested in what specifically is changing.

 

[washguy]

"better fuel control".

Terry I thought your fuel control is pretty damn good as it is.....so better fuel control means safety? HP? response? Wash

 

[Terry@BMS]

Too early to quantify what "better" means in this case. But, at a minimum, prettier data logs?

 

[KLR STINGER]

You know where to find me Terry. I'll email for test firmware

 

[Terry@BMS]

I just posted it to the n54tech thread on the last page, could use some logs.

It's on n54tech already
