No we're good on logs at this point, and only would need to see them if you have some specific issue you need our help with.

Been reading this thread with great interest. I have the JB-1 for my 2016 Red Sport. Thinking of upgrading to the JB-4. My question is, if I have my car on standard map 1 on JB-1, is the extra 3lbs of boost constant? Meaning, if I'm just cruising down the highway, is the boost at 3lbs higher at that point, or is it throttle dependent? Also on JB-4, if you set the boost to be lets say 3lbs higher at 2500rpm ,and cruising down the highway at 2500rpm, the boost will automatically be 3lbs higher? And if so, is this good long term? Thanks.

For Stage1, the boost added is a function of the boost being generated. Under cruise you have no boost, and thus no boost over stock. At around half throttle you'll start picking up boost over stock with the Stage1.

Thanks, what about the second question?

No, if the car is cruising then the stock computer is targeting zero boost. All of the BMS tunes will still target zero boost under that condition. Otherwise your MPG would suffer for absolutely no benefit.

OK, but i see people here are setting their boost based on RPM. Is that only under acceleration, and not a cruising RPM?

It has nothing to do with acceleration, it has to with pedal input/throttle position. You can accelerate to 100 MPH with 30% pedal input, it just takes longer than if you had 100% pedal input.

I don't know enough about the Infinitis, but the JB4 boost is typically added somewhere between 50% - 100% pedal input.

Not really sure what you're asking but the boost settings entered are what are targeted at 100% throttle input. Again, nothing to do with lower throttle positions.

Just got the JB4 upgrade from JB1. Do I need the ODBII connections put in for this to work or is that just for logging? I am trying to get the program up on my laptop like I did with my JB1 and it cant find the JB4. Thanks.

You need it plugged into the ODB port.

I have a few questions, Terry.

Regarding the car you took to the 1/2 mile event, was that a Silver Sport with a JB4? Any idea how the power compares to the same car on JB1? Were there any other mods?

Also, I noticed that I can climb up pretty high on the torque converter and brake boost off the line, but when I'm at speed (form a roll), the throttle is cut if I get on the throttle and brake at the same time. Granted, the turbos spool up relatively fast, but I really want that brake boost capability. Has anyone found a way around this?

Thanks

Question to you experts on here since Im a newbie.

I had the JB1 at the +4 setting and the car was a beast running 93/e85 mix.

I put the JB4 upgrade in with the settings below and the car seems way slower.

1500 4
2000 4
2500 4
3000 4.5
3500 4.5
4000 4.5
4500 4.5
5000 4
5500 3.5
6000 3
6500 2
7000 1

I noticed in MAP 6 there is a boost safety box with a value of 3 in there by default. Is that limiting me to +3 and ignoring the higher values in the RPM map or are there setting elsewhere that may be limiting the cars performance?

Thanks.

If you want tuning advice just record a log of the run. The boost safety has no effect on anything unless using map3, in which case it acts the same as Stage1.

I am no expert, but first thing to do is send some logs to Terry to look at, it is possible that maybe the 4.5 is too much, sometimes less is more, especially on these small turbos.

Also fuel quality matters when pushing the upper limits, if it wasn't really E85 (depends on where you are but winter E85 is only required to have 50% ethanal) this could cause a not true E30 blend. Or the 93 is bad, I had that happen, had to turn the car down from map 6 running plus 6 to map 2

Next fill up slowly turned it back up and was back to map 6 running 7 plus

This is on a SS not a RS.

Regarding map changes... When choosing from the pick map option on the top right hand corner, once I choose a differant map, is that it? Does it automatically save on the board it self? Anything else I have to do?

Only save option I have is under the user adjustment tab...anyways I think I got it ... Whenever I connect it, it automatically loads up map 1 for me..... Other issue in having is trying to find the hole to guide the obd cable.

Edit: Nvm I'm just blind

When selecting maps from the gauges side there is no save option. Just click on the map you want and that will remain until changed.

Hey Terry,

I was doing a high speed run today using JB1, and at around 130-140 mph my VDC and CEL turned on for the first time ever. The car doesn’t seem to be running any differently, and I drove another 100 miles with no problems, but the CEL won’t go away. The VDC light turned off when I restarted my car. Any ideas what could be causing the CEL?

Thanks

There is no way to predict what your CEL is. If you have a JB4 use it to read the code. If not, use an OBDII reader to check the fault.

It might be as simple as hitting the speed limiter which can trigger an under boost CEL.

Thanks for quick reply.
I’ll get an OBDII reader within the week. Do you think I’m safe to drive another 300 miles with the JB1 connected? Car drives normal, same power and all. It doesn’t feel any different since the CEL appeared, no noises or anything. Im thinking it’s just an error since it ran fine for a week earlier at higher boost. Anyways do you think it’s safe to drive? Or should I disconnect it?
Thanks again

Edit- also the CEL stays on when the JB1 is disconnected

You're fine. Just read the code ASAP before it goes away on its own. You might not be able to grab it once it goes away, every car manufacturer is different with that.

I would suggest going to an auto parts store like AutoZone or O'Reilly. They typically can read it for free.

But your car is fine. If you had a JB4 and the JB4 mobile app, you'd be able to check the log and know exactly why your car is showing the light.
