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.

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.

Sounds good! Just ordered mine for my gts yesterday! cant wait!

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.

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
