Default Stinger log map 5 with WMI - 05-22-2022, 04:52 PM

Went to the track today and got a log of one of my runs and want to know where to go from here. Run was done on map 5 with WMI enabled on all maps.

Car is a 2022 GT1 AWD mods are: JB4, BMS WMI, BMS intercooler, BMS OCC, K&N intakes, ARK secondary DP, HKS plugs and Velossa Tech air scoops. Fuel was 100 octane Sunoco and WMI was boost juice.

Thanks in advance!

Log looks great but damn!!! You left at like 20 psi, that's pretty hard, what was your 60'?

60' was 1.74 with a 3.99 0-60 according to my Dragy. Left right around 10 psi, 2500 rpm. I don't think this trans will hold to the 3500rpm that 20 psi was at lol

Any advice on how to step things up? Got a dyno appointment on Friday and it looks like I've got room to step it up a bit. Logs show 0 timing corrections which makes me thing 100 octane + WMI might be overkill for what the factory timing curve and maybe leaving power on the table.

You launched at 3363 RPM at 20.6 psi, really. Log tells all. You had a bit of wheel spin but it grabbed pretty quick. At 20 mph it had settled to 20 psi. Map 6 would be your next step...

Data looks good to me. If using WMI why not map7? Then just raise additive as desired to get boost where you want it!

IAT spoofing would be useful here too I think to get IAT down and timing up. We'll be posting more on that in a couple weeks.

I guess I better take it easier on my launches!

I ran map 5 because I knew what PSI it ran. Intended to run map 7 but with the number of drivers there, it was close to 2 hours between runs and I still had a lot to do on my 1 day off.
I did do a 20-70mph on map 7 last night with additive set to 65, boost maxed at 22.9 and had 0 timing corrections across the board.
I'm guessing the IAT spoofing will trick the ECU to up the timing higher and sooner? I'll be looking forward to trying that out!

Here are 2 20-70mph logs on map 7. The log from 5-23 was at 65 scaling and to my eyes looks good.

The one from 5-24 was at 70 scaling and there was a hiccup at the beginning of 2nd gear where it reduced the throttle. Only thing I can think of is maybe it revved too high in first? Hit 6614 rpm and right after the throttle dropped. The rest of 2nd and 3rd pulled like crazy!

Both logs were set to 65, maybe it didn't save before you logged? Either way they both looked solid. At 22 psi without an ECU I think you can go to 70 safely and the car will be happy. The throttle closing is a signature move with stock ECU and revving over 6k. It's time to learn the paddle shift
One other thing, I'm confused by your FF and Buty bias combo. An FF of 45 is good if you've had overboost issues but where did you come up with 55's in Duty Bias? I might be missing something but there seems to be no rhyme or reason for the down, up and down through the RPM range.

I will fully admit that the acceleration caught me off guard lol I typically try to shift between 5-5.5k
My understanding is that FF is a global adjustment and Duty Bias is for fine tuning. I was getting overboost around a specific rpm so I dropped FF to 45 then upped Duty Bias to 55 above and below the rpm range it was overboosting to fine tune. Is that pointless?

Well, you raised your duty cycle from 50 to 55 from 3000 to 4500, but.... during WOT, even at the bottom of the shift the car barely goes below 4400 between shifts so those only count while you first step on the gas from a dead stop. If you were over boosting in that range then I think you went the wrong way, but I'm still not sure what you were trying to accomplish.
Here's another way to look at it. You're at FF 45 right now, lets keep it there. Change all the Duty Bias settings back to 50. Bump up your Meth Additive to 70 and log. With an FF of 45 there should be no over boosting. From there if you wanted to fine tune your duty bias we can add some at the top end of the RPM range to smooth the boost curve out.
Another approach is to put FF back up to 50, and we control boost or over boosting with the Meth additive, and tone that down to say 60. With that approach, we can still fine tune Duty bias at the higher RPM's to smooth curve.

That makes sense, we can chalk it up to me not really knowing what I'm doing. But it's all fixed now! FF at 45 and Duty Bias all 50. This log has the additive set to 70 an with no hitting 6600 rpm

Yes Yes, log looks way better. You're GTG. I try not to give fine tuning advice on a public forum because folks will copy and wonder why it doesn't work for them. So, as far as a great daily I think your car is set up perfect right now.

I get that completely. I really appreciate your help! Car should stay as is at least till SXTH gets the remote unlocking ready for the market. Following that thread on stinger forum closely!

I’m in the same boat, looking forward to more timing.
