We basically have the same mods and im on 93 and I noticed my car's logs are much cleaner consistentlyif i go +3.5 max throughout 1500-7000. I've ran Map 2/Map 6 with +4,,+4.5,+5 tapered and while there were clean runs, the clean runs weren't as consistent.

Megan LDP's being installed today, a member suggested its better to let the turbo's breathe better than up the boost past it's efficiency zone which makes sense to me

I tried 0.5 higher

Yep, had to ship it all back to BMS. They said they'd take a look and replace anything that needed it. Hoping to get back in action shortly. Concerned maybe something with the last app update did something but pretty sure I connected after the update without issue.

That's a bummer. I know driving around stock must feel like driving a 2.0 right now

It's surprisingly not bad since I still hit ~ 11 psi with no map. Think it's the ******* ********* and y/mid.

Anyone able to give me some insight into these? My main concern is the boost reading on map 1 and 2 (and every other map). The module reads and logs actual in map 0 but the second I switch into adding boost it seems to think it is capping it at 5psi or so. Or at least much lower than the goal of the maps. Currently have an E25~ mix in the tank.

I also feel a hiccup around 3k that I'm wary of but I'm not sure whats going on with that.

Yes something isn't working here. What mods? Ever touched the head exchanger?

Completely stock 18 except muffler delete, and flex fuel sensor

[Terry @ BMS]

Is it a new install that has never worked. Or was it working fine for some time then suddenly acting up?

its been installed about 3 weeks and all of my auto logs tell a similar story from what I can tell as my planned logs.

[g0t2bmiirii]

Got 2 short logs to show You Terry.

The more recent one (today) was on sport mode, 80 degrees, from 60mph to 100-105mph with low fuel light on. The other one i forgot

Hi Terry, Need advise.

I own a 2017 3.0T premium and recently bought a JB4. I use 93 gas and use map 6 with the attached boost levels. My car is completely stock. Temp around 90s

Attached the log from my recent run. Need your advise on the graph and also if the map 6 that i'm running is good for premium.

Thanks

[PRQ50]

Not sure if this has been discussed before on here, are these a good add on with JB4?

[Q50Philly]

Hi Folks - After installing fuels wires, enabled Future UseD bit 0, I have my first CEL and AFR(#1) reading is stuck at 25.5...AFR2 normal at 14.7 on idle. I checked posi-taps and pin positions (thanks to tips from Ddnspider and Jrobohm!) and they are installed per YouTube install video).

Do you know which side AFR(#1) vs AFR2 is located?

[Terry @ BMS]

AFR1 is the driver side IIRC, connector must be unplugged or something.

[Q50Philly]

Thanks Terry!

Hi Terry. Need your review of my logs. I’m new to jb4. I’m seeing AFRs close to 25. Please let me know what needs to be done.

AFR looks normal other than the start. Are you brake boosting or something as fueling appears to be in open loop mode.

Let's see a log on map1 and map2 for comparison.

Hey guys, what gauge are you using to monitor your charge air temps? IAT? Trans Temp? Basically I am trying to make sure my Heat Exchanger is actually working but not sure which gauge is monitoring the key data to ensure it is.

My AMS HE typically is +15 over ambient - unless I have been pushing it (more so now that I have my BMS WMI Kit dialed in... )

BMS WMI

[PRQ50]

My frozen boost type 101 runs about 10F over ambient (dashboard indicator) not IAT.

[Serstylz2]

Same with my FB101. I have Oil Temp, Trans Temp and IAT gauges selected along with Map AFR and Boost. Trans Temp has always been 5-10 degrees more than the outside temperature

[Rs400newbie]

Anybody know where I can find info how to connect the fuel it sensor to the Jb4 module? Thinking of pulling the trigger on the Fuel-It/BMS kit. TY

[Terry @ BMS]

It's in their install guide, just plugs in like the FSB. Once you have it generally installed email me for a firmware update that is needed for both meth & flex fuel sensor inputs.
