We’re does the ewg harness connect to on the jb?

the ewg is an extra cable that you need to buy. The instructions are found in the 1st post.
To confirm the firmware you need to connect to the box. Since you cant via the BT you may want to get the data cable as well to connect via laptop or phone via the OTG method

Added EWG_6 firmware to the first post and could use some logs to verify its working as it should be!

Hi Terry, I've just updated my jb4 with the ewg6 firmware, everything looks good except the fp_l data, it's fixed at 345 value and doesn't change, oil temp, 4 cylinder logging looks good

There is no low pressure sensor on the car, so that is normal. I have it showing EWG WGDC so we can use that to determine if cars have the EWG connector added on when evaluating.

oh, ok!

great to know that, do you have a description of what the future use d bits does on the n20 jb4?

also, I noticed something weird today, the gauge sweep happened after the engine warmed up a little, it didn't do when the engine was started.

Mine does the same thing......

Is that the JB4 actually restarting, or just a glitch?

It does it every time I start the car and start driving.

gauges should sweep when starting car. If it does it while driving its probably a sign we have the CANbus speed cranked too high. I'll slower it slightly in T1 in the first post. If it continues, you can also try FutureUseD bit #7 on for slower speed sampling. The slower speed will still be much faster than the previous EWG_5 firmware.

Terry, if I may ask, what changes has EWG_6_T1 brought compared to 5?

Awesome! Great work as always.

"2) Added load and calculated torque logging for future N20 back end flash map development."

Is this for the Bootmod3 or MHD flash that is being developed?

Useful for either but we'll be posting free MHD maps once they add N20 support, which they report will be in a couple months.

It happened for me after a 4th gear WOT Log, with the updated firmware 6. I'll try with FutureUseD bit #7 on.

I have updated to firmware 6_T1 but at the first starts i did not get any gauge sweep.
Then after a couple of hours i started again the car and gauges did sweep as supposed, but after 10 minutes of driving they sweep again whike driving. Now i have activated the FutureUseD bit 7, but i couldnt try it for more than 5 minutes because i was arrived home.

Terry, what you mean by saying that gauges should sweep “where wheel controls are not disabled.”? You mean when you’re not connected with the JB4 Bluetooth app on the smartphone?

I’ve also another newbie question: can the JB4 handle a ***-less ********?

This is less vital, but I also noticed that when parked/stopped, LED MAX brightness mode flickers when enabled.

My gauge sweeps but only after engine starts and car is idling. It's almost as if it's delayed lol. Is there a setting to switch this off in the meantime?

Hello Terry,

I tried some more firmware 6_T1 even with "FutureUseD bit #7" on, but gauges keep sweep sometimes while driving.
Is this causing any problem to the car?

Since it seems multiple cars are having problems with the gauges resetting and the higher speed CANbus I'll just remove the test firmware for now. Will revisit when the back end flash mapping tools are available.

So you suggest it should be better to go back to 5_T2 or keeping the 6_T1 will not cause any problem even if CANbus resets?

I'd go back to 5_T2.

Even if I really loved the Oil temp, I think it's not worth keeping 6_T1 just for that....hope it will get released fixed soon!

@Terry, is it possible to release the firmware with the gauge sweep disabled? Or perhaps implement the oil temp feature to the 5_t2 firmware? I don't know how much work would be needed for that but i'm in the same boat as Mat28.
