Has anyone noticed or had issues with your intake temperature holding at the exact same temperature or not changing unless it really rises?
Mine works fine for about 5 minutes then doesn't move for sometimes 15 minutes even if I stop at the lights for a bit and do some wots.

Doing 3rd wot won't even change the temperature sometimes.

Interesting, could be a faulty sensor. Have some logs of a longer run?

No the 3.5bar is continental and the 4bar is Bosch.

Yes, WD40 will dry out Orings and turn them into a slimy mess.

The best Lubricant you can use on Orings that are making a seal, is Molykote DOW55! If the orings see any motion like on Spool Valve style paintball markers you use DOW33 from Molykote. Dow55 is very thick, and causes orings to slightly swell, great products that has been around for years!

FWIW on orings like that I just use a little motor oil. Never had an issue with it.

I've got logs of all sorts.

It just works from start to normal iats, then it just stays at xxx f and is like its more delayed rather then Instant reading and maintains the same xxx f temps compared to stock which would change a few single units nearly continually.

For example give it a quick slight boost and its goes down about 3 f but with the 4 bar I have to do at least a 3/4 redline 3rd wot and it might move 3f then quickly go back to xxx f.

I don't have jb4 i just wanted to know if others are experiencing the same delay

Flash should stay the same, the JB4 sends back stock TMAP values, so it won't be compatible if you try to adjust the TMAP in the flash. Just change the TMAP setting in the JB4.

No flash changes needed, except in high elevation situations, where the 'Map Conversion' 0.50v value should be changed from 2.90 to 2.50.

Here's a test result we did of the latest firmware's "auto calibration" feature for the 4bar TMAP sensor. The JB4's readings are overlaid with those from a standalone data logger that has a highly accurate, manually-calibrated MAP sensor.



That's some nice accuracy.

Normally just one or the other to avoid wasting support time... If we're working via email we don't want to go copy the same information to the thread and vice versa.

I remember seeing it somewhere, but can't find it now.
What's the boost scaling on fuel gauge with the 4bar?

Stock TMAP is mid(10psi), full (20psi).

The boost scaling now is set so that full is whatever your boost safety setting is. That way you know if it gets to full things are close to switching to map4.

Don't know, would be in the firmware notes. Been that way awhile though.

This is the o-ring that will make it nice, snug, and tight without worry, just make sure to spray some WD40 on the o-ring to lubricate it.

Went to Home Depot tonight and got the supplies you recommended . Only issue was they only carried m6x16 not x15. Do you think m6x16 will work on er charge *****?

Idk, depends on how gapped the hole threading is or if its dual tracked. Only one way to find out, if you can't screw it in with your bare hand then no.

Use judgement to know if you going to strip the hole if you force it.

Terry Hello I've installed the 4bar tmap sensor in the JB4 user settings change the N20 to (2) but I've been getting codes (2ABC charging pressure sensor) and (3100 low boost mode engaged.)

Hope you can help me.

If you are using one of our BEF maps and have not made any changes to it, and firmware is current, then maybe a faulty sensor.
