Canadian Stingers with JB4 - What fuel?

Sorry not able to read every thread. My "ping" system is disabled as I participate on a lot of forums daily and don't have time to follow up on everything. Didn't know anyone was trying to reach me here. I'm actually pulling for the Raptors to win tonight so I'm not anti-Canada.

For consistent log help post them in the n54tech thread!

While I was here scrolled back looking for a CSV to review and didn't see any.. Shrug.

Hi Terry, can you check in the first page or second page. There are logs there we wanted you to take a look at.

Also we want to upload more logs with 91 From Costco and 91 From shell.

Map 2 & PetroCan 94 here. @Terry@BMS - care to look over this log and see how you feel about Petro94? I'm curious to know too.

13.19s @ ~108mph @ 2200ft / 2995 DA, AWD, FYI. IAT probably plays a role in the fact it wasn't in the 12's?

Sorry for delay!

Looking at timing it's roughly the same in each cylinder so that indicates the octane is generally sufficient for the boost target. The DA and IAT are certainly slowing it down a bit. Although I'd expect more like 110mph+ than 108mph here. I'd suggest trying map3.

For track stuff you can also use a dragy to test under various conditions to confirm if the car is running slower than it should be or if it's perfectly normal and just the specific track conditions you were racing under that day.

OK do it! The main thing is to look at timing cyl1-6 on the different fuels to check for variances.

Do you think you can adjust the JB4 to make Canadian gas better? I'd like something that converts Canadian 91 to American 93.

 

[Terry@BMS]

The fuel is what it is. The key is identifying which fuel works best for you (the 91 or 94) and then what the best performance level is for that fuel.

Is there much risk turning up to a higher map? The car and knock sensors will "always" pull it back to a safe margin, meaning nothing should blow up if just testing more boost? I grew up with old school turbo Dodges and boost was a dangerous game. I understand new cars with knock sensors should be safer. Basically I should just be "slower" or no faster on a higher map if having issues running a higher map?

 

[Terry@BMS]

Minimal extra risk at the levels we're talking about here, main issue is you'll go slower if going too high.

If I use JB4 map1 only with Canadian 91 octane and Catback as only other mod with the factory gapped plug, should I be fine regarding boost/timing/knock/sparkplugs??

Revvdmedia,
Have you tried Map 3 on your car yet as per Terry's recommendations?
If so, how's it working for you?

FWIW. i am running. Shell 91 on Map 2 with absolutely zero apparent issues. My plugs are gapped to .022. For now I’m just going to stick with Shell 91.

Can I assume that you also had no issues running the Petrocan 94 on map 2 as well?

There are no Shell stations local to me so the Petro 94 is my only option.

Get some logs and have @Terry@BMS take a look.

Map1 is super mild and designed so almost anyone in any situation can use it. The attention to detail doesn't really start until maps 2+.

So this is very interesting, I thought I would have to install new plugs and re-gap them regardless of what map was used but if Map 1 is safe on stock gapped plugs...hmm

Nothing yet, been busy.

Safe shouldn't matter when it comes to changing or not changing the plugs. Regapping the stock ones is just silly, and the $75 the new plugs cost that are then regapped is such a minor expensive for a massive change in feel and reliability.

So this data isn't incredibly conclusive since runs were performed in different locations, different days, etc, but I thought I would present some summed findings from my logs.

Things to note is that this data was extrapolated from Excel, using =average calculations, etc. I considered the 0-60 run starting from the last row of cells with 0mph before the speed went up, and ended the run at the logged 60mph cells. Average ignition is a little lower since the car dumps ignition to zero for two rows of cells when shifting from first to second gear, and also there is boost ramp-up in first gear since this is a 0-60, which brings down the average boost value as well.

Shell 91
JB4 indicated 0-60: 5.400s
Average Boost: 10.71psi
Average Ignition: 10.11
Average IAT: 87F
*No launch control, street test

Petro 94
JB4 indicated 0-60: 5.150s
Average Boost: 11.41psi
Average Ignition: 9.87
Average IAT: 121F
* Launch Control - Held for about 1 to 1.5 seconds, on a prepped drag strip

Husky 94
JB4 indicated 0-60: 5.575s
Average Boost: 11.82psi
Average Ignition: 9.14
Average IAT: 97F
*Launch Control - held for about 2 seconds, street test

If you want to measure performance really a dragy is going to be needed using a measure that takes traction out of the equation like 1/4 mile traps or 50-100mph. But if you need to do it another way you can do fixed gear pulls in say 4th gear starting at 1500rpm to redline, and then in the logs compare the time passed during each from 2000rpm to some specific stopping RPM, along the X axis (tenths of a second).

Of course, the 0-60 logs are a big "for what it's worth" considering when I examined them, my Husky 94 run SHOULD have been faster if everything else was equal and the same otherwise. I don't get out to do high speed testing often. The biggest factor is the wife doesn't get it and I don't feel like explaining it, lol. I'm too nice I guess.

 

[Terry@BMS]

I hear you.

The logs will be useful too so you can look at timing advance in cyl 1-6 under the same conditions for both fuels. If the performance is similar but one fuel has better timing.. It's a good indication to stick with that fuel.
