Guys... in new firmware of JB4 (v31) Duty Cycle in logs means the calculated torque.
How can I understand this from my log? For example if my DutyCycle reach 2600 level, how much Nm it means?

Adjusted boost by gear cap menus to reflect 0-5000rpm = 0-20psi, making adjustment on the fly easier. Added 3rd gear under menu 15

hi Terry this means i can also control boost at 3rd gear as well from menu 15?

Yes. Not a big concern for OEM turbos but those running larger twins on weaker tires will find it handy when doing roll races, etc.

The calculated torque has no basis in reality as the JB4 and/or back end flash maps alter it. It's just a reference to use when doing flash map programming. The scale is min to max = 0 to 1000lb/ft (not NM).

Does it mean that if I have 2600 Duty Cycle on my log - it means around 371 lb/ft?

7000 = 100%, 2600 - 37.14%, so 2600 ~ 371 lb/ft ?

I am wanted to see how much torque I have without stand. Just for information. Thanks.

Terry,

Thanks for the update, quick question regarding the rescaling of Map 3 with n20 sensor, do you have a table which can be applied to work out the new additive number = what boost target? Also I assume the guys with the stock sensor haven't been ammended?

No, I'll have to make a new map 3 scale for those with the 3.5bar TMAP. But it's basically 0 additive = 15psi peak, 75 additive = 25psi peak, with around 2psi taper to redline.

The number will not tell you how much torque you have.

Hmm my firmware 31 is acting strange. I just updated and ran map 1 and 4 and both are boosting at least 20psi. It's on 4-2 and back end is pump gas.

Not sure what's going on no maps target correct boost levels

Sounds like a hardware issue. Sure you had ISO firmware before and clipped diodes? Either way if you need help you'd have to post a log to the support area.

I thought about this last night while logging.

Requesting potential new feature on JB4.

Press both up buttons on steering wheel (opposite to engage JB4) to begin logs, press again to end logs.

Thoughts?

So dangerous having your eyes off the road to reach your phone to end logs, whilst doing high speeds.

I like to do my logs to the relevant range keeping it short and sweet when reading

why end a log manually? they're like 10kb, I'm not worried about it running out of space on my phone and can edit easily later. plus you can adjust the auto timeout to end the log 3 sec after you leave WOT or whatever if you really need it cut off

By default with the windows interface logs only record over half throttle and you can fit up to 8 min of recording in to one log. That's like 200 pulls.

I'm running low on mana and my crystal ball is at the shop. So we'll have to do it the old fashioned way with a log in the support area.

I prefer console games that get me away from a PC and human interaction. Playing through Witcher3 right now.

Heard that was awesome. It's on my list to play. About to start some retro action, though.

Maybe a wastegate issue then, such a low duty cycle should not be hitting such a high boost target. Try 2000rpm on menu 12. We may need to adjust the firmware to allow that to go down to say 1000rpm for extreme situations.

Terry is oil temp as a parameter on the roadmap or planned?

I ask because i'm using the jb4 mobile app to display all my relevant gauges and this would be super helpful.

Thanks!
