Default Hazard signal flash, switches to MAP 4 - 01-22-2016, 07:47 AM

08 E92, MAP7, E85 BMS flash, E50

Was WOT in 2nd gear, hazards flash and JB4 switches to Map 4. I figured it was be the JB4 safety feature described in the sticky but I didn't see the SES flash and I was able to switch back to MAP 7 without restarting car.

What could have triggered this?

Most likely a lean condition or overboost. That won't trigger an SES light and will just kick you to map 4. If you don't correct the issue, it will likely happen again.

Post a log.

I noticed boost gauge (fuel) was pegged so I changed boost safety to 21 and the problem hasn't reoccurred.

I attached two logs, looks pretty clean to me. I can't hit boost target after 35000 PRM, is this typical for stock turbos with 70K on them?

Looks pretty good. FF will probably drop a bit more and adjust your FOL up to 60 so it doesn't max out at tip in.

In the notes in the jb4 thread, it says 1 ses flash is over boost, 2 ses flashes is lean AFR, 3 flashes is low fuel pressure. Was it changed to the hazards flashing? Because I got kicked to 4 the other day when traction control kicked in, and I got a pair of double hazard flashes

Did we ever confirm this?

I was referring to an SES light, not a flash...here is the guide for that...

"My SES light flashed and the JB4 switched to map 4 / low boost. What do I do now?

The JB4 has several active safety systems that will trigger SES light flashes.

The first is the over-boost safety. If boost exceeds the value you've set under user adjustment the SES light will flash once and the JB4 will switch itself to map 4 until you restart the car. The default setting is 18psi. Common causes for this are setting the value too low for the map/intended usage, improperly configured or defective wastegates, or JB4 setting problems.

The second is the run-lean safety system. If your air/fuel ratio (either bank) runs leaner than 14:1 over 4500rpm for more than a second the SES light will flash twice and the JB4 will again switch itself to map 4 until you restart the car. Common causes are maxed out fuel trims (see E85 notes above) or o2 sensor faults. Note any o2 sensor fault must be corrected for the tuning to operate properly.

Another commonly triggered fault is low fuel pressure. If your high fuel pressure drops below 7 (~800psi) the JB4 will flash the SES light three times and switch to map 4 until you restart the car. Common causes are an inadequate low pressure pump, too strong of an E85 mixture for your tuning/fuel pump, or a failing high pressure pump."

The reason I ask is I noticed the hazards flash the other night when I was doing logs and it bumped to safety map reason 1.

Anyone from burger tuning, did this notification switch from SES to hazards or is it something else?

I'm not positive, seems it used to be the hazards flashed in the past. If you're running the latest firmware, which is recommended, then it should be the SES light.

Hello Steve, I just bought and installed a new JB4 with the bluetooth connect kit and it appears to flash the hazards instead of the SES light. I appear to be running the latest firmware (shows as 32/6//2 on the mobile app) and i am also able to go back to another map immediately after it auto switches to map 4 because of the AFR being lean.

You need to fix what is causing it to go lean. You'd want a post a JB4 log of it coming up if you need our advice.

This is the log from this morning when it happened. This was the first time it occurred and I will see if i can get a better log tonight.

So I have the same thing happening. Terry told me that it was due to my trims being maxed out. It looks the same on your log. Notice how your trims go to 50 which is maxed out and then it changes to map 4 and 8psi of target boost. He recommended I do a menu 1/7 reset. Hope this helps.

This seemed to solve the problem for me. I did a few pulls and at no point did it kick down to Map 4. I've attached a new log as well, and it looks like the AFRs are more consistent and trim level is down.

Better to do logs in 3rd, try not to hit the kickdown or get a kickdown blocker.

Raise your FOL to 85.

I changed the FOL and avoided the kickdown. I tried to do pulls but got a cylinder 5 misfire. It only happened one time (will look into spark plugs/ coils if it happens again) but the FOL changed to 90 afterwards. Should I drop it back down or leave it? Any advice is appreciated!

Leave FOL at 90, that is fine.

I'd recommend adding the pump flash and if cylinder 5 continues to have misfires, start swapping components with other cylinders to find the root cause.

This happens to me too.. when traction control kicks in hard repeatedly on wet roads it kicks me to map 4 with a hazard flash.. I can switch back to any map on the fly without restarting immediatly..

Could the fuel cut on traction control be causing it to run lean for a split second engaging the safety on the jb4??

You are suppose to turn off traction control when logging. If it is wet outside I would not turn it off or go WOT.

The JB4 safety is pretty straightforward - my JB4, going all the way back to JB4 G4 board, has always been flashing hazards when I hit a safety. But I also have gotten an SES IN ADDITION to the hazards flashing.

FYI, count the # of times the hazards flash - that equals the JB4 Safety number (1-5) that caused it. Or just look in the Read Only menu of JB4 app, for the Last Safety value. Also in log file header rows.

Yes, turn off DTC when logging, and also ASC if you feel safe enough about it.

As Steve mentioned (for the millionth time), 2nd gear is not good to log in.
