If you need tuning help post a JB4 log here and we can confirm it's running as it should be.

anything I'm doing wrong? i looked to see if i needed an update but was a little apprehensive to start the process after reading the instructions. currently have JB4_PORSCHE-912_2_2.HEX firmware file version 9112/2//7.

thanks
Can you post a log so we can take a look?

Are you reading boost from the boost gauge on the car?

I attached a log of a few runs. I didn't realize the logs were combining into one giant file until i uploaded it. sorry.

the original problem I was having has been resolved. it was a slightly loose obdII connection and the gauges were not receiving any data. So i think the first time i tested, the jb4 wasn't actually doing anything.

The file i attached i did a few runs and when i get closet to redline jb4 auto switches to map 8. this happens whether i run map 1,2 or 3. i have an automatic pdk so i am not sure why any safety would kick in.

Not sure what the problem is but anytime i get heavy on the pedal the map switches to 8.

ill try and do some other runs and separate them appropriately.

Hm when I open the file in the windows software nothing shows up. Combine log is the normal option and it should be left on auto mode so it only records at full throttle.

I was able to run a few more logs. Every time I step on it, the map changes to map 8, even if I am running map 0, it will still switch to map 8.

I disconnected from the app and now it will not reconnect. keeps giving me an error to check the hardware connection. I did, and everything is nice and snug.

not sure whats going on.

I added a few more logs. I separated them per run. I will reset the app to combine logs if that is easier.

Set boost safety to 21 and grab another log on map 2.

thanks Payam

I changed boost safety like you suggested and it worked. The map did not revert back to 8. I did a few runs on both map 2 and 3. i am attaching the log.

thanks for your help.

I am going to be adding the soul bypass pipe s which should be next week.

Awesome!! Looks like you're making some more power on map 2 and 3 from what I can tell. Do you have any access to e85? Maybe throw a few gallons in to mix and bring the octane up a bit.

I added some e85 fuel and rode around for a bit. for some reason, the boost safety reverted back to 0. I set it to 21 and ran on map 3, but it still switched to map 8.

when running map 2, it doesn't happen.

not sure what to make of it.

I see the problem, bug on our side.

I posted the update to the app so you should be able to update it yourself, it's version 912 (for 911.2) v2.3

Ok, I updated the firmware and went for a spin. On map 3 it still switched back to map 8 at certain times. It doesn't do it on map 2.

Yes that's the lean run safety we have in there. How long has the E85 been in there? It may need a little more adaption. But if the last_safety = 2 continues then drop down in map until it doesn't. And if it comes up on even map1 then just go back to 93 octane.

We'll be exploring more aggressive E85 tuning in the future.

i went out a bit this morning and everything was running smooth. map 3 did not revert back to map 8.

i was wondering how to get a little more boost at lower rpm. i was reading that you can set the default waste-gate position higher so the turbine spools faster. can you elaborate a little on that and if so, where should i set it so i can get a little more boost at launch?

thanks,

Yes higher WGDC is needed for more boost up top, but at the moment we don't have that functionality included in the Porsche JB4 like we do for other models. It's something we'll be working on though!

Hey all,

I received my new IPD Plenum and Soul C.A.T. Delete P.i.p.e.s (PSE with the O2 sensor) and before installing these I want to make sure everything will run correctly or if i will have to flash the ecu in addition to the JB4?

thanks again

No need at all, the JB4 will adjust what's needed after a couple of pulls

Default First JB4 Log - 05-18-2020, 08:33 AM

Hi - I've had the JB4 on my 991.2 TTS for about a month. The car seems to be running great, and I really like the software interface. I'm not sure I "feel" as much difference on the butt dyno as I expected, but maybe that's because the car already feels so frickin' fast even stock tune.

I am attaching a log with 3 separate WOT pulls. Timestamp 0:00 to 117:75 is Map 2, 117:75 to 238:00 is Map 0, 238:00 to end is Map 3.

Car has stock cats with a Soul X-pipe as only mod. Fuel for all runs is E15. Runs are at about 5,700 ft elevation.

My questions about the logs are:

Do I have the right logging parameters turned on for you to evaluate? Are there any parameters I can turn off so the graph isn't cluttered with unhelpful data?

Do the logs look like everything is running correctly?

Do you see the impact of my high elevation, such as lower peak boost than you'd expect from cars at lower elevation?

Is the E15 looking to be an adequate fuel choice for Map 3?

If everything looks good, in the near future I plan to try Map 4 on 95 octane.

TIA!

For a 991.2 TTS the base ECU boost request is lower than I have seen. My base was 17psi down low to 18.5 -19.0 up top.

Fuel octane might be hurting the base.

Looks like the JB4 is doing it's job by adding the target....it's just adding it to a lower than expected base.

Terry or Payum might have a few ideas.

Looks good overall. Update to the latest firmware first, we made a few mapping tweaks that may hold more boost up top.

In my 20+ years of multiple other forced induction cars, I've come to expect noticeably lower peak boost at my over a mile high elevation. Please explain/let me know if this car is somehow immune to the 20% less barometric pressure.

I updated the software at install just 4 - 6 weeks ago, but will sure check to see if that is not up to date.

Dragy and Dyno data coming soon.

Thanks Terry
