After lots of testing and success we're happy to announce our release! JB4 system for the 2017+ 991.2 Carrera/S/T and Targa/4S and the GTS!
Gains of up to 40whp and 60wtq on our base lower maps. With our methanol or CPI kit, you will see about 60whp and 80wtq on the higher race maps.
Plug and play device, no ECU flashing or removal needed. Easy quick install as well with real time data and logging abilities.

Dynojet numbers will be released soon. Lower intro pricing right now:

This is pretty cool! Kudos to you guys for giving us enthusiasts options I remember using a JB4 on my F80 and MK7 R... very happy with the results and kept me cozy till eventually flashing.

 

Just to be sure not for GTS models, right?

 

this is interesting! Of course I could have predicted something like this... My ECU is on Cobbs bench as I type this!

LOL...

 

no ecu flash? so all good for warranty?

 

Just placed my order.

Having used BMS products in the past, looking forward to using this!
I'll post my thoughts and an install guide once I get it.

 

Yeah I used JB4 on my BMW a few years ago, it was great. Easy to flash. I look forward to trying this. It'd be helpful if they indicated what type of mods are required for each map.

 

From the BMS forums...


Map0 - JB4 disabled
Map1 - 2psi peak 91 octane
Map2 - 3psi peak 91/93 octane
Map3 - 4psi peak 93 octane, race gas, or ethanol blend
Map4 - 6psi peak ethanol blend or race gas
Map5 - 8psi peak ethanol blend, race gas, CPI required
Map6 - User adjustable by RPM map using settings on user adjustment page. Setting of 5.0 would request 5psi over stock at that specific engine speed.
Map7 - Progressive WMI integrated map, boost profile under WMI flow adjustable on WMI page.
Map8 - Low boost VALET map (400hp simulation!)

 

Amazing. I have a JB4 on my Golf R and love it. You 991.2 folks are in for a treat, no warranty issues with this route

 

Omg awesome!

i was wondering when it was going to happen you guys had 718 jb4 done for awhile now but no 991.2

 

Following...if truly no warranty or issues seen with other piggybacks, this is super interesting.

 

What about logging? Would this log anything additional over say what a Cobb access port can log?

 

install looks tricky though?

 

This is what i been waiting for.... will this work on 991.2 GTS?

 

I guess I'll jump in in regards to warranty and logging:

Warranty

You have to understand how the JB4 works. Say you have sensor A that feeds to the DME. The JB4 unit goes in between Sensor A and the DME. The controller inside the unit alters the signal being outputted by Sensor A (usually a voltage value) and outputs a value that is below the target for that specific module. DME reads that there is a delta, and reacts to correct delta by changing the corresponding parameters (waste gate actuation, fueling, throttle position, etc...)

The DME is still reading (and storing) values that are within factory spec...

That said, you're still running outside of factory spec in reality. A JB4 can throw codes, though a DME tamper code probably won't be one of them.

If you need to go to service, you can pull of the unit and most of the time nobody will know it was there.

If you blow a turbo, or require some major work on your car....there are ways to find out.
If you go into the dealer for a service with the unit installed, chances are you're gonna get asked about it and/or reprimanded (aka, warranty issues)

It's not a Porsche approved product, but it is a clever product. For day to day use, JB4s are nice ways to get a power bump without really messing with the car...

Logging
You won't get fuel capabilities like Cobb AP...

But, you'll have access to a decent amount of channels (Boost, target, RPM, IAT, WG, timing, AFR, etc)
The bluetooth unit is also pretty slick.
