I’ve installed mine. Need some help understanding which map is which. Also the Bluetooth is not connecting to the the gauges. It will for a moment, but then goes to zero. Two gauges will work but doesn’t seem real time.

Terry @ BMS 03-30-2019 04:40 PM

2 Attachment(s)
Had a customer connect the JB4 connections in the wrong spot limiting boost. Be sure rainbow patch is on the MAP sensor as shown!

Brown109 04-25-2019 12:17 PM

Do any of the maps currently available require any modifications?

Terry @ BMS 04-25-2019 02:57 PM

No they don't.

leogets954 05-21-2019 10:39 AM

Ordering mine now for my 718 GTS. Will be running a ******* ********. Do I need to use a specific map, or will I need an O2 Spacer?

Terry @ BMS 05-21-2019 11:14 AM

Inside USA we can't provide any advice. Outside USA there is a passive delete option for those.

leogets954 05-21-2019 11:34 AM

Sorry Terry, I should have mentioned the car will be used for track racing only. Where would I find information on the passive delete option?

Fred V 05-23-2019 01:33 PM

I just purchased it and will have it installed very shortly. Very excited. The dyno charts posted on the order page are for a base model running E26 fuel correct?

What are the power gains for each maps on regular 91/94 fuel?

leogets954 05-23-2019 01:58 PM

I dyno'd my stock GTS on sunday. 91 degrees, 65% humidity, 700miles on the odometer. made 354hp/ 335torque.

I'm very curious about the base model since this is what I have, and everything seems to be about the 2.5

Sounds good! Steve can help you crank up the boost too if you need. :)

leogets954 06-05-2019 08:58 AM

Has there been any updates on the progress of Maps 5-8?

Terry @ BMS 06-05-2019 02:53 PM

No we haven't done any higher maps yet, as Steve is continuing fuel development so we can determine how far we can safely push it.

Terry @ BMS 06-06-2019 11:01 AM

Harnesses are on back order for a couple weeks I think, but we'll ship it as soon as we can.

Fred V 06-25-2019 06:50 AM

Had it installed, have been running map 4 for around a month now, and 3 pretty agressive track days. The car performed wonderfully.

Had a cooling system fault on the last day, but temps didn't exceed normal ranges and once I cleared the codes they never came back.

Also curious about the O2 sensor. I'm in Canada and my next purchase is a ******* ********, would the tune take care of the CEL or would I have to erase the faults at every start?

Cheers!

Terry @ BMS 06-25-2019 10:03 AM

Passive delete is an option for outside the USA work, should work but we've not tested it yet on the 718.

I will end up giving it a try I think. How about the boost spike issues some people are reporting without a tune?

Thanks,

Terry @ BMS 06-25-2019 10:14 AM

Until I see a JB4 log of it it's hard to evaluate. If you have any tuning issues with them share the log and lets see what we can work out!

Terry @ BMS 06-28-2019 01:25 PM

Added updated firmware to first post

sniper260687 07-10-2019 09:53 AM

Mine is on the way for my 718 cayman s.

If i run map 4, how much E85 can i filled up? gallons wise combine with 91 gas

Start with something like an e20 blend. Maybe 3-4 gallons to a full tank of 91.

Log on the lower maps first and post the logs here so we can evaluate before moving up to map 4.

So would it be better to start off just with 91 map 2?

Then go from there with a blend?

Sorry, coming from an RS3 on FULL E85, the power is very much wanted on the 718

Yes, start with map 1 or 2 with 91 octane. Then do an e85 blend and get a log on map 2 and we'll go on from there.

Okay sounds good.

I have the mobile app.

What email or to whom should i send the log to?

sniper260687 07-20-2019 05:56 PM

I sent an email with some concerns about the logs.

I starting logging today but had way too many logs after pressing the button only once

Got it! Working with you in the emails :)

DJB 09-18-2019 03:51 PM

Contacted your support via Chat and they recommended I ask the questions here.

Im looking for a way to mildly increase the power of my base 718 without changing the ECU to avoid problems with possible warranty work down the road. You guys have a good reputation so was interested in learning more about your system.

What does it have control authority over? i.e:

Timing? retard timing if knock occurs? Reduce timing further than stock when boost is increased above stock boost?

Lambda? Can it control (increase fuel) for increased boost above stock?

(Not sure if timing or Lambda needs to change for a few more lbs boost)

Safety features: What is most important to me, is that all the factory safety features remain active and that if something goes wrong due to bad fuel, sensor or injector failure etc, that the engine can protect itself. Does this still remain fully intact? Any limitations here?

When Knock occurs does the ECU still pull timing as it should protecting the engine?

It appears your unit monitors the ECU through the ODB port and that may be what allows your unit to understand if something is not working going well, like knock or running lean?

I see with the mobile app you can do some data logging. Can you check for knock and other PIDs that would allow one to monitor how the Tune is working?

If still in Beta, are there any concern you might have using this product on a 2018 vehicle given it would be use for a stage 1 or mild boost in power as mentioned before?

Re clearing codes in ECU, I've read on forums for other platforms your unit can clear the codes or readings that may alert the factory that car may have had a piggy back on it. Does this apply to the Porsche 718 platform as well?

This tuning device is very basic, but has lots of gains.

The stuff you're referring to is mostly for flash tuning.

The JB4 will increase boost, the ecu will compensate for fuel on the other end. All factory safeties and tuning is all still in place so it feels like a stock car until you step on it.

DJB 09-19-2019 11:35 AM

OK got it, thank you. Tried to send you a PM, but the account wont let me apparently.

Once the device is removed and codes cleared(if any) is there any trace left in the Porsche ECU of the JB4?

Can you log on the device to see if there is any knock happening to verify the tune # selected is safe?

Do you know if the 718 has wideband or narrow band from the factory?

I see mention of running more ethanol, does the factory ECU have an ethanol sensor to make adjustments ?

Payam@burgertuning.com

No trace when removed, as you stated.

Yes, the JB4 has logging which you can do from your laptop with data cable or phone via Bluetooth add-on. That's how we can monitor fuel trims, AFR, boost, timing etc.

IIRC, this would be a wideband. Terry would know better, so I'm not 100% on this.

No, we will monitor fuel trims, fuel pressure, and AFR with ethanol blends to ensure it is safe and can keep up with the mild blends we are mixing in.

DJB 09-19-2019 06:15 PM

Thank you!

Terry @ BMS 09-19-2019 07:47 PM

Fueling is full time closed loop with wideband like all other modern turbocharged engines. :)

DJB 09-19-2019 10:16 PM

Great, thanks Terry!

Is there a way to log or derive if the ECU detects knock with the JB4?

On a base 718 Cayman with 91 octane, do you have any dyno results from either your or your customers testing? Hoping to make a safe ~45hp if possible. Ive only found the 2.5 liter results posted.

Fred V 10-04-2019 07:01 AM

With the new maps now supporting meth, how would one go about setting this up? Which injection settings should we use for each maps? Des the tune do everything automatically?

I also can't find a kit for Porsches on your website, is it the same kit that you sell for bimmers? How safe is it mechanically, not accounting for possible leaks?

If you're mechanically inclined you can do the install yourself.
We're working on a PNP kit with a chargepipe for 1/8npt port.

If you don't want to wait, you'd have to drill into your stock stuff for that.

Methanol injection with the JB4/FSB integration is the safest option you can get! We have safety implementations programmed into the JB4 to keep the engine safe and happy. The JB4 can revert to stock mapping if it see's AFR too lean, fuel trims maxed out, no methanol flow, etc :)

DJB 10-04-2019 11:09 AM

If running 91 octane, is there benefit and is it safe to run an E85 mixture on the stock map of the 718 if you are running an autocross or HPDE event? (3-4 gallons E85 to a full tank?)
