[Mr. 5]

I recently went to the strip and added a JB+ to my current GIAC race tune and ran an 11.77 at 119.9. I thought I was boosting about an extra 2 psi but it turns out that it was about an extra 2.5 psi.
The question that I think everybody asks is, "Is this really safe?"
Well, one thing is for sure and that is that it is much harder on the turbos but what about everything else?

I went to European Auto Source yesterday and added about 2 gallons of race gas. One gallon was MS109 and another gallon was 100 octane. This was added to about 1/4 of a gallon of 91. So, I had a little over 100 octane in the tank and figured that it was safe enough.

I was curious about a couple things...
-What is the boost?
-How are my AtoFs?
-What does my timing look like?
-How hard are the turbos working?

O was actually quite surprised. Everything that GIAC tuned for stayed exactly the same. The only thing that rose was the boost.
The timing stayed perfect.

The interesting thing is the logs of boost when I added the JB+. The ECU thinks that the actual boost is lower due to the JB+. This is the reason why the turbos boost more to try to hit the target.

When I went to European Auto Source, I added the race gas and then ran the car on the dyno just to let the gas get through the veigns. Then I wanted to do a baseline with GIAC without the JB.
The first 2 runs were without the JB+.
When looking at the maximum area under the curve, it looked like my best run had the peak numbers of 414.73 WHP and 450.73 WTQ

I then stopped the car, added the JB+ and then did 3 more runs.
Again, when looking at the maximum area under the curve, it looked like my best run had the peak numbers of 438.14 WHP and 484.09 WTQ

Here is the Legend:

Pic1...Dyno graph of runs without JB+ with Boost
Pic2...Dyno graph of runs without JB+ with AtoF
Pic3...Dyno graph of runs with JB+ with Boost
Pic4...Dyno graph of runs with JB+ with AtoF
Pic5...Dyno graph of Best without and Best with JB+ with Boost
Pic6...Dyno graph of Best without and Best with JB+ with AtoF

[Mr. 5]

Here are the logs.
Remember...

Runs 1-2 are without the JB+.
Runs 3-5 are with the JB+.

Here is the order:

- Timing
- Boost
- Duty Cycle
- Throttle

NICE! wish you logged your timing as well

[Perfectus]

That's awesome that you tried this, doc'ed it and shared. I just installed a JB+ last night to my stock e92 and have it set to just under 75%. The car is still adjusting I think. But I'm pretty happy with it so far.

Three questions for you:
-what setting did you have the JB+ at?
-Are you going to keep the JB+ installed?
-Did you just leave the JB+ "hanging" or did you zip tie it to something? I feel like I need to attach it to something...

Very nice mr5. I run this combo to and worked pretty well with meth.

[srt8/bmw]

Nice smooth runs.

question: since you mentioned that you had thought boost was 2 psi above, and it turns out it was more like 2.75- was that the default setting on JB+ or did you actually attempt to dial it back slightly?

He did. Look again

[AhmEd_B_Stylin]

438whp are you fucking serious ?!!!!!!!!!!!! This is stronger than any tune out there ! You ran meth or race gas only ? You think results would be about same with 93 pump + 100% meth ? WOW unbelievable !!!!

[dzenno]

Ahh, he posted it after That looks really good...one thing that worries me a bit is the GIAC timing curve...its really aggressive, going all the way to 15deg at redline...with the added boost there is no room in the stock timing curve but then again we've seen these boost levels and timing curves with piggies for the last 3 years and it is the settings I ran many times with the procede (18-19psi and 0 ignition correction) and there have never been any issues...with the JB+ though I don't think this is safe to run on the car all the time...I wouldn't mind running it like you did but with datalogging on the side as the results might vastly vary with temps/weather but maybe the ECU would adjust for that as well...

I had the JB+ a little over half the pot.
If I were to use it again, I would dial it down but I just wanted to dyno the same as what I ran at the strip the other night so this is the power that I had when I ran the 120 mph traps.

Race gas AND Meth.

I understand but remember that this was with race gas AND meth as well.
What is interesting is that bigger turbos are boosting this and the block is taking it so the main worry for me is the turbos.

This is a recipe for disaster....

What do you think results would be on a 93 pump +100 meth ? Similar ? or that wouldn't be enough octane to run somewhat safe ? Thanks ! The car feels crazy fast ?

I'd say with meth and race gas its a recipe for 500whp with upgraded turbos and a recipe for Mr. 5's 120mph run have to be careful with the jb+ though and definitely wouldn't advise anyone run this daily

once in a while is ok ? lol This setup on 93 octane + 100% meth would be as effective ?

Look at the logs and explain your thinking.

No not just "once in a while"...no one without proper datalogging and understand exactly what they're doing should ever run this setup...Mr. 5 understands the risks and know what he is doing by looking at datalogs...i just wouldn't have run it at the track before datalogging like this but better now than never

I agree with you.
This was added for a map for the 1/4 mile strip on the best fuel.

No. I would run no less than 100 octane plus meth.

So running Procede or JB4 at 18 psi with meth is less dangerous ?

[Mr. 5]

Here's another thing that I like.
The boost at redline with the JB added is almost the same as without.
I like how the boost increases in the "safer" spot.
It's definitely not running 17 psi all the way to redline like other tunes.

I really don't need to look at any logs. Just use common sense. The JB+ is a dumb boost controller. Crap one at best. You are adding extra boost but there are no timing adjustments whatsoever for that extra boost. Nor there are any for the increased ETGs. Yeah, you may get away with a few runs like that, but it won't last long.

Stacking piggybacks and tunes has NEVER been a good idea on any platform. I highly doubt that the N54 is much different.

I told you this is a recipe for disaster. See what I mean... First victim of experimentation is lined up. LOL
