Stratified S-OTS maps for the JBR Power Path Intakes
 

We are proud to announce that we've teamed up with James Barone Racing to offer Stage1 and Stage2 Off the shelf (S-OTS) maps for the MazdaSpeed and Mazda MPS vehicles worldwide.


As a COBB Pro Tuner and with thousands of hours of tuning experience on the Mazda platform we are able to offer these maps that can be paired with JBR's top-quality Power Path Intakes to achieve excellent performance, driveability, and reliability from your vehicle.

If you're looking to unleash the full potential of your MazdaSpeed, we are of course happy to offer our Custom Tuning packages where we can tune your vehicle to achieve the most from your exact modifications, setup, and driving environment.

I just installed the JBR stage2 intake and flashed the stage1 S-OTS 93 octane map; wow. After I get my internals installed I'll flash the stage2 S-OTS map...which should hold me over for a short time until I get on your list for a full on custom tune(s)...(easy access to E-85). Thanks to you both for great products!

I read the big thread!
Couldn't have been a better match.

Stratified = Experienced Soldier! James Baron Racing = Weapon Of Choice!

Thank You!!

Finally got my HPFP internals installed and after verifying solid fuel pressure, flashed the S-OTS stage 2 93 oct map; great, great stuff! This will hold me over for a little while...maybe.

Finally got my accessport and flashed in the stage 1 map yesterday and plan on going to the stage 2 map when my internals get here (autotech backorder fail). Anyway i like the option of being able to use the FFS and LC options with the Cobb maps is there any way to add this into the stratified maps as they are locked?

Only way to have these maps work on anyone's car is to have them locked.

I will consider the FFS option BUT ... I am not a fan of it. I still see cars run lean in the next gear (randomly) when FFS is used and I don't like that. It's still a bug COBB hasn't addressed yet and it makes me a bit nervous having it in the S-OTS maps.

FFS also leads to overboost in next gear:(

ahh good to know wasnt aware of the issues with the FFS, kind of unfortunate as i like the feature.

I installed my stage2 jbr intake and flashed the Statified OTS stage1 map. I'm seeing 1700-1800+ HPFP and 14psi during WOT runs. Is this normal? I'm coming from stock everything with the stock stage1 cobb OTS. With that I was seeing around 1600-1650 HPFP readings and 17psi during WOT runs.

The Stratified maps will vary boost to hit certain load targets. So in warmer weather you will see boost increase. This is perfectly normal and this is using the advanced load targeting strategy of the ECU where torque output is targeted versus just boost pressure (like in the current COBB maps).

Once you have an HPFP installed, try the stage2 maps.

@Lex; Do the S-OTS maps only work with the JBR?

It would be awesome to be able to purchase the S-OTS maps as a substitute for the Cobb OTS maps.

This would work for new AP customers as well.

A lot of people are still running Cobb OTS maps. I think this would be a nice option.

The S-OTS maps are calibrated to work with the JBR intakes. They incorporate a lot of the design logic that goes into Stratified maps while ensuring that they are safe. Beyond these a custom tune is really the next step. Selling OTS maps will not work so well because each vehicle reacts differently and you are better off with a custom tune in the end if you're spending the money.

I have an HKS intake and flashed a Stage 2 Stratified OTS and my LTFT are between 2.8 and -1.6. Went from a modified by me Cobb OTS to this map and I have to say the difference is AMAZING. I will suggest anyone with a Cobb OTS to give these a try and keep and eye on the LTFTs to see if you are good

Alex,
I am using your stage 1 OTS with my JBR Stage 2 on a 06 MS6. How many miles do you suggest of driving before the trims settle and what should the min and max LT%'s should I expect.

Thanks!

Trims will vary depending on your local fuel, weather, etc but generally they should be within +/-10%. The ECU will trigger a CEL if they go over 20%.

The trims will generally settle after 40 miles.

I can't second this enough. My first impressions have been very good and a very clear improvement over the tweaked Cobb OTS Stage 2 v231 map I was running...and even more so over the untweaked Cobb that over-boosted like a bitch.

I'm saving the more detailed eval after I hopefully get a slot on the dyno at MNM this Sat.

Please report back we the numbers to see how you did. Also, are you going to dyno Cobb OTS and then Stratifies OTS for comparisons?, that will be awesome.

Can't dyno back to back because neither has personalized MAF curves. Both have to "learn" after being loaded because they aren't designed for a specific car.

You certainly can dyno maps back to back. The learning happens at low throttle only - at WOT it doesn't matter.

Remember thought that the S-OTS maps are meant to be safe and fairly mild so that they can be used in a variety of climates and with varying fuel quality and parts installed.

It was my understanding that the WOT fuel trims were determined, at least in part, by the LTFT's the car learned in part throttle applications.

I'm certainly open to the possibility I'm wrong but I've seen my belief posted many times by other users as well.

Don't want to toss a fresh tune on the car that doesn't have the MAF curves calibrated and run a bad AF ratio WOT on the dyno.

You are wrong. No need to settle fuel trims for WOT.

You can go WOT immediately on a fresh flash. The fuel trims learned at part throttle are only applied at part throttle.

Alrighty, here's what we've got.

Keep in mind, my car does NOT have the JBR intake system these tunes are advertised for although my LTFT's were all within 5%.

Run 1: 275hp/325tq
Run 2: 284hp/324tq

I then flashed a franken-map where I worked with the WGDC tables of a Cobb v231 OTS map to get the car to stop over boosting...I then did some drivability tweaks and brought over the all the required load values from a v210 map into the v231.

Run 3: 287hp/314tq

Now here's the thing, I had all 3 runs logged plus by looking at the AFR on the dyno printout, you can tell between the two of them I hit enough KR in both S-OTS runs to trigger significant richening of the AFR. Run 1 was the worst and it reflects in the dyno'd HP.

Unfortunately I'm no guru and can't diagnose what caused the knock nor can I see in the S-OTS maps to tweak anything. I much prefer how the S-OTS maps drive but KR scares me.

Last thing to mention, I noticed that the Trottle Position % on the S-OTS pulls gradually increases as the RPM's increase while the Cobb based map pegs immediately and stays there. I'm sure there is a logic behind that but I found it curious.

Anyway, here are the media goodies.

Runs 1, 2, and 3 on Google Docs for your browsing pleasure. I highlighted the 4k RPM range where the KR kicked in and highlighted in orange the moment knock jumped.

Run 1 - S-OTS

Run 2 - S-OTS

Run 3 - Franken-tune mix of Cobb v231, Cobb v210, and me.

Attached are copies of the dyno printout and the franken-tune I was running.

When logging on the street, do you notice the same KR with the S-OTS maps? It appears the IC was fairly hot when starting the pulls. If the timing is too hot for the fuel you are running, running a 91 octane map will take care of it.

Finally, if you want a custom map for your particular car ... then get in touch.

I did see the KR on 2 of the 3 log pulls I made.

Here is one log where I didn't experience any knock but the car had only just gotten close to operating temp.

Looks like a 91 octane map is better suited. Or try a different gas station.

I'll toss the map back on and try a different station. I really wouldn't think I should be having knock problems on an OTS build being conservative and all. I've been using Sunoco 93 so I'll try a different brand and station.

93 octane is not the same everywhere unfortunately :(

Interesting thought from the other thread. Makes you wonder. I'll mess around for awhile and see how things turn out. I still have almost 3/4 tank right now so it'll be a bit. lol

Good Morning Alex

Right now my only mods are the JBR stage 2 on my MS6 and I am running your stage 1 map. Would adding a test pipe result in me needing a custom tune or will the stage 1 map be ok? Right now I am within 10% long term trim.

Thanks,

The only worry here is your fuel pressure. On most cars it should still be fine. However, I would take a 4th gear WOT log from 3k RPM to see that all is well after adding the test pipe.

thanks for the quick reply.

why does a test pipe effect the Fuel Pressure, I trust your expectise I just wonder why that could happen so I understand.

I am going to use the stock DP, but I thought about replacing the second cat with a test pipe. Is there significant gains by doing so?

Removing restrictions from the exhaust generally leads to higher boost that may overwhelm a stock HPFP. It is unlikely that just a test pipe will do this with a stage1 map but it's something to keep an eye on.

If you plan on doing anything beyond a couple of mods to your car, just do yourself and your engine a favor...upgrade your HPFP. Your wallet will thank you later when you don't ruin your ride.

Purchased a Cobb AP this week and got it today. Installed the Stage1 S-OTS
93Octane and took the car out and did a data log while testing it out.

I'm assuming I need to get used to the boost since it seems like its dependent on pedal/throttle position? I dunno if I am sounding nuts but in stock form if i give 50%, boost would slowly build up but after mapping boost stops so it works different. I'm sure thats normal just wanted to throw that out there.

Also, what a difference. This is how the speed 3 SHOULD feel. Holy torque batman. I kept getting traction warnings in 2nd gear, I never got that before - :hypnotized:

Great product. I was debating if I should ever try out the stage 1 cobb maps but from the looks of it, stay away.

I've been much happier with the drivability of the S-OTS over the Cobb or the OEM maps. That difference in throttle feel is a huge benefit in my book. It's a lot easier for me to control how much power is being put down whereas the Cobb and OEM felt more like an on/off switch for a gas pedal.

Thank you for the kind words. The throttle mapping is indeed different in the S-OTS maps than OEM or the COBB maps. It is a lot more linear so that boost can be better modulated using the throttle.

Oh ok good to know, I thought I forgot how to drive for a second there... when boost stops I was like uhhhhhh but then I floor it and my face lit up like north korea being nuked :P

here are datalogs from today. I'm a little concerned, should I try the 91 map to compare? Looking for a second pair of eyes. This is stage 1

Thanks
