Just got my dyno results!

[Bepis_Corgo]

Hello all, recently installed a JB4 on my 2018 RWD Stinger GT1. Unfortunately, awaiting an email with the results, but I have a picture of what I pulled today. Interestingly, Map 3 and Map 5 had no difference.

I did 4 runs: map 0 (only other mods are BurgerTuning CAI's, and Denso 2 step cold plugs gapped at .022), map 1, map 3, and map 5.

Got 400 to the wheels on map 3 with 439 torque! Not bad. It was about 60 degrees outside here in NC today.

I was surprised that on map 0 I pulled 355 to the wheels. The fuel/air ratios seemed great. My only issue is, my app is only reading boost and nothing else. Anyone run into this?

Overall, very happy with the numbers! Probably need to run E85 for map 5 to see a difference I'm assuming. This is my first vehicle I've ever modified, so excuse my uneducated ass if that E85 statement is false.

not bad. I would expect a bit more torque though on map 3 (or map 2). if you are just running 93 octane I'm guessing Map 2 would have been just as good. I have the same set-up and don't usually see much more boost out of map 3. guessing the fuel quality is not fully supporting map 3. the app will read everything if you have the OBD2 cable hooked up.

Looks good !

The stock performance is enough to glue me to the seat. Do these mods affrcr driveability ?

Yes, I'm running 93. Weirdlt enough mine only reads boost. The OBD is plugged all the way in, so not sure what the issue is.

 

[StingertimeNC]

weird. Terry will probably respond. may be worth emailing BMS and asking too.

Modern transmissions and drivetrains don’t have anywhere near 20% loss especially in RWD applications. Probably more like 12%-14%.

Nope. With the JB4 I am able to flash maps in an instant. My commute is 25 miles each way, and I drive it in Eco in map 0 (stock), and with my intakes and plugs I still average over 25mpgs. I drive like a grandma unless I'm in twisties or take it to the drag strip.

Interesting, that's good to know. So my crank power at peak on map 3 is about 440~ then?

Honestly, I really don’t like to ever try to predict “crank horsepower”. For me I think trying to predict horsepower at the crank is pointless. Horsepower at the wheels is what moves the car. I think we should only ever use actual measured horsepower values at the wheels.

I actually prefer drag results to dyno results. You can never fully match air intake conditions from the track on a dyno. I would much prefer to see trap speeds, 1/4 mile times, 1/8 mile times, and 60 foot times over “predicted” crank horsepower figures or inflated torque numbers.

$25 and a day at the Rock will tell me a lot more about a car’s power than a couple hundred dollars spent on a few dyno runs.

What part of NC are you in? I am near Raleigh and go to the Rock quite often when it is warm.

I got almost 39 mpg on the way home last night after a 116+ mph trap speed.

I agree, just curious! I'm by Emerald Isle/Jacksonville. I drag mine in Richlands.

Post up the JB4 logs from the dyno to see how your boost, timing, and AFR looks and use that to give the numbers context.

If the app is only reading boost it's likely OBDII/CANbus isn't active which will dramatically reduce the power output on higher maps. In that case waste of a dyno likely...

As above said track / draggy will give you a better indication of car performance vs crank HP or even peak WHP... If ever you want to use WHP always compare how much you gain vs stock or previous mods in the usable RPM range.

But if you want to speak HP with your friend that do not know much about cars use 400 WHP / 0,88 (or 0,86) which give you around 455-465chp.

How do I "activate" it? I have the OBD reader plugged in, and it reads boost, but that's it

Edit: the log only shows boost.

Edit 2: I'm an idiot... I had it plugged sideways. Everything is reading fine. Will do a log after a leisurely drive from work.

 

[Terry@BMS]

Now that CANbus is working expect a lot more HP next time you dyno.

So that's what eco mode looks like in the center cluster. Neat.

Here is the best one I have ever done. Kind of incredible that the car is actually capable of this.
