Stratified S-OTS maps for the JBR Power Path Intakes

[Speed3_BigV]

I tried the 93 octane stage 1 map tonight using 91 octane fuel (ohh I can feel the evil stares lol ) 91 is the highest I can get around here, there's 94 available but its a 1 hour drive to the closest station -__-

Car always ran perfectly with the 91 octane map, but I wanted to see if I could squeeze out a little bit more out of it using the 93 octane map. I suppose the major difference between the 2 is slightly more aggressive timing at the cost of knock?

So I went out and logged 2 pulls in 4th with the 91 octane map that was already flashed, then flashed the 93 map, drove around slowly for 15-20 mins and logged 3 pulls in 4th while monitoring live KR data.

To be honest, the logs show absolutely nothing wrong, the data is virtually identical, there's no knock whatsoever, it's as tho I'm still using the 91 octane map. But the car seems to be a little more responsive and looks like it's pulling slightly harder in the higher gears.

What power gains should I roughly expect between the 91/93 maps? I know each car is different, also fuel and location matter but a rough estimate?

Thanks!

What what are we to expect on the stage 2 91 octane OTS map? I know I asked this in a personal thread but wanted to ask it here as it could be important info for people looking over their logs

[chomorro]

I want to try out your OTS maps but when i click on the download link im getting taken to another web page with crazy characters all over it and not downloading anything.

What am i doing wrong LOL

Macbook pro using firefox and safari same results.

For us Mac users right click then click on "Save Linked File As" to download.

I just swapped out my Cobb Stage 1 OTS for the S-OTS Stage 1 running 91 octane. What a noticeable difference, the smile on my face was as big as the one on my car. I need to run the log tomorrow but I am getting what sounds like some knocking at partial throttle in 1st and 2nd early in the RPM range. I'll do some more reading too and see what others have found.

Probably going to run this tune until I can get a catted downpipe, new TMIC and e-tune later this summer. Or just make the short trip to BC and have it done in person!

Ahhhhhh i should have thought of that LOL. I will try it out tonight and flash the new map. I havent experienced any knock yet but i havent been stomping around town all day either. I do get slight backfires though at partial throttle just cruising occasionally, but i think thats normal for us ms3's with downpipes.

We would need about 2-3 hours to tune and I have a great area for this. Alternatively I can meet you in Washington, I go to Bellingham often. The knocking - is it registering as KR? Or is it something making noise in the engine bay?

Yes, right click, save as will do it! Try it out and I hope you enjoy it.

I am happy to see you guys really enjoying these S-OTS maps. They are baby versions of the custom tunes we offer.

Each car is different and it also depends on what other modifications you have. The 91 and 93 maps differ in terms of timing mostly. If you are seeing 0 KR on a 93 S-OTS you will benefit a good amount from the next step which is the custom tune.

The important parameters are:

- LTFTs should be no more than +/-10
- AFRs taper to around 11 by redline
- Boost will vary depending on your car's setup, altitude, temperature, etc.
- KR should be less than 2* under steady state WOT.

Lex, I'll PM you later today about the in person tune. I haven't had the chance to run a log yet but in the 10 miles driving to work the audible noise seems to have gone away.

[happykat]

Lex,
quick question i am running the ots stage 2 on 91, mods are listed in my signature and quite frequently in wot i will hit 20-21 psi of boost. My question/concern is that is this normal am i at risk of going zoom zoom boom?

[bhamitgeek]

Was actually pretty disappointed in the Strat maps personally. I thought they ran ok...till i dropped a regular OTS from the AP on and my numbers and power was much better with their maps. I tried first when I picked up my ap i put the st 1 map...93 oct on and it felt pretty good. I had one of my fellow AL Nator folks suggest I go ahead and put the Cobb OTS on so that I could go ahead and maf cal and get some numbers ready for my internals and test pipe. I did and felt noticeable difference in improvement. Same with the ST2 map. Anyhow.. every car reacts different I guess due to environment. to each his own.

Do you get 20psi at spool up for a little bit or does it hold that boost level? It's not a dangerous boost level and the maps are load based so boost levels will vary depending on several variables including the modifications on the car and ambient temperature.

You're absolutely correct in that every car will act differently. The S-OTS maps are meant to be more consistent in nature since there are quite a few controls in place for boost for example than with the COBB maps. So it's likely that you are seeing higher boost numbers with the COBB maps. A custom tune is the way to go for something fully optimized for your particular car and environment.

Until the weather cools down and you start boost spiking. At least that was one of my primary experiences with the v231 OTS from Cobb was boosting so high the car would cut out. The v210 maps were better about boost control but had their own set of weird quirks.

While I do wish I could get inside the S-OTS maps and see what's going on, the numbers I get from logs and the feel of the car day to day shows the attention that went into making these maps perform safely while still providing a boost in performance for a wide variety of cars.

Lastly, the S-OTS maps have a much more linier throttle response than the Cobb. While the Cobb will feel more powerful to some because of the on/off switch like performance of the throttle, the Strat will allow more refined control over the power letting you ride the edge of traction much more reliably in 1st/2nd. Also, my dyno runs show almost no HP/TQ difference from Strat to Cobb while the drivability was much better on the Strat.

Sorry for the semi-rant above but I'm really aggravated at Cobbs seeming lack of refinement in their OTS offerings. The fact that most everyone I know who has or is running the v231 OTS experiences over-boost yet Cobb has never released any adjustments burns my ass.

[bhamitgeek]

Yeah down here in Alabama it wont get cold or much less cool for that matter any time soon. By that time Freek will already have me tuned. I modified the cobb st 1 and st2 maps with Snaild's throttle table tweaks and really made the response much better on the cobbs so its not so on and off.

True enough about Alabama. My time in Mississippi says fuck living that far south. lol

My only recommendation then would be, if you aren't, to monitor your boost levels periodically. Cobbs boost control really was a pile of shit on my car and from the talk of others, it's a pile of shit period on v231. Mine had WAY too much WGDC which woudl cause me to spike on throttle then the error correction would cut cut cut but by the time my boost got to target the ECU would have taken too much WGDC out and I would dip under target for the remainder to redline. I made power....but it was weird power.

[bhamitgeek]

yeah...I see your point.. Right now I am already on Freek's list...he told me about 2 weeks so its coming up and it will all be straightened out.. THanks for the input though.

It holds at boost level. Before I put my internals in I was running the stg 1 s-ots and pushing 15i-16ish psi, then internals went in so i flashed the stg 2 s-ots went up to 19-19.4 psi. On Saturday i got a cobb bpv installed that and noticed that my psi was around 21psi.

This is just a case of adding more parts and them having an effect on the tune. The more parts you add such as the BPV for example, the more you affect the boost/load response of the car and at some point you will need to look at having the tune adjusted for these parts.

thanks for the insight lex. I figured it was a result to the addition of parts, but I wanted to make sure. A custom tune is in the works but I want to get an upgraded top mount before hand.

Send me a quick log and I can glance and see if anything is really amiss while you're waiting for your top mount.

Log the following and do a 4th gear pull 3k to redline:

Accel. Pedal Pos.
Actual AFR
Boost
Boosted Air Temp
Calculated Load
Coolant Temp
Engine Speed (RPM)
HPFP Actual Pressure
Injector Duty Cycle
Intake Temp
Intake Valve Adv.
Knock Retard
Long Term FT (LTFT)
MAF Voltage
Mass Airflow
Spark Advance
Throttle Position
Vehicle Speed
Wastegate Duty Cycle

Lex, i just did 2 4 gear pulls and only got up to 19.79 psi. It must of been a mixture of things. log is attached tell me what you think.

Looks ok from what I can tell but you didn't use the parameters listed above and didn't go WOT until later in the rev range.

[happykat]

shit i see what i did. I put the parameters live data instead of the data log. Ill run a couple more times.

[Agent_Orange]

My car loved the Stage 1 93 S-OTS map from the first mile. LTFT's within -4/+4, solid AFR's, much better than Cobb's, even with maf cal. Can't wait for a custom tune from @Lex;!

[happykat]

Lex,
here is the correct parameters.

[Lex]

Originally Posted by happykat Lex, here is the correct parameters.

I don't see any issues or boost close to 20psi. You might spike a little when going WOT at higher RPMs but I don't think you'll have issues.

[happykat]

ok, today was way warmer compared to the other day when i noticed the 20s psi. as long as you dont see anything too abnormal i am good with that. In about a month or two i will be doing my tune. Thanks for the help lex.

Here's a 4th gear log with the 93 oct stage 2 map loaded up

No log attached.

lets try this again

[theurgy]

Gas quality is a big factor.

Well I was running Sunoco and switched out to Shell and saw no change in the KR levels.

[theurgy]

Yeah it's weird, I run Chevron 94 here but it still knocks like 91 octane, I wouldn't even dare to run 91 here

[iammike]

My guess is because I'm close to sea level maybe. More dense air. I'll be going home to Missouri to visit here in a few weeks and will be doing some logs there...see how they come out.

[Lex]

Unfortunately it's gas quality. I've tuned cars all over the US, Canada, and internationally and actual octane varies greatly even if the rating written at the pump is the same.

@Lex, with your S-OTS maps, is there any way to make a change to where the EGR codes can be turned off? I am planning on trying your stage 2 map tonight when I get in from work, and I am currently planning on doing the custom tune within the next month or so. I wanted to see how my car reacted to your OTS maps before I do my custom tune with you guys. I have a JBR EGR delete kit waiting to go on, but I thought I read something about your maps being locked and not being able to turn EGR codes off. Please let me know.

Thanks!

I was using Ultra 94, which used to be Sunoco but it Petro Canada now.

If you're going to get a custom tune, I would first try the map and install the EGR delete when you are getting the custom tune.

Currently the EGR codes are in place in the S-OTS maps.

[GOT 2RBO]

Thanks Lex - I will do that and report back here on my thoughts. I can't wait to get my custom tune!

[iammike]

@Lex; So timing is the only difference between the 93 and 91?

Just for the sake of it, I loaded the Stage 2 93 map yesterday and took 6 logs and in every one of them saw KR over 1.5...and a couple of times over 2.5.

Today I loaded up the Stage 2 91 map and did 8 logs and think I only saw over .5 for a couple of cells. Overall much more time spent at 0.0 KR and a few runs never had any KR at all.

As much as it annoys me (because I'm like this) to run a 91 map for 93 fuel, it's obviously the quality of fuel in this area since I've tried two stations and two different brands with virtually the same results.
