If using a back end flash use mode 4/2. Otherwise, you'll get whatever boost the flash has programmed.

meant to type 4/2 actually, but it would be nice if you could update the first page of this thread to reflect the changes to the boost curves for maps in 4/2.

See the thread for 3rd party JB4 interface.

He's not working on the OSX version for a few weeks, he's more involved in the Android and iOS versions right now.

I might have missed something, but are we now not able to log fuel trims as negative (-) percentage? Before, a value below 8 would indicate a negative (-) trim.

Correct can't see below 0 now. Sorry, something had to give there. Tired of the confusion as to how trims would exceed 33%.

updated to 28.81 firmware version, and i had my first gear boost limit set at 9.0psi and 2nd gear limit set at 14.0 psi. upon plugging in my laptop after driving around for a little bit, i noticed they had gone up and down .1. so i reset the 1st and 2nd gear boost limiting to 9.0 and 14.0, but each time i do that and save settings, they reset back to being down by .1 and up by .1. possible bug?

What TMAP sensor are you using?

What interface/app are you using to upload firmware?

That is what happens when you squeeze a 0-360 word in to a 0-255 byte. Some decimal points will round up or down.

Now that we have separate maps for the back end flash I'm working on a stronger map 7 for you guys. If anyone is bored and feels like testing it just email me.

Dmac told me it was due to the 3.5 bar TMAP sensor conversion and a rounding issue.

Stronger in the flash or stronger in the JB4 firmware? I guess what I'm asking...is there more boost or more timing?

Idk if you still want logs, but here are some logs with the 28.81 firmware,everything seems to run smoothly on my end. I took the liberty to reread the 4/2,4/3 setting I have couple questions for you Terry. Just outta curiosity before this change took place, on the default setting 4/3, wasn't the JB4 safety enabled (Map 4) even with the flashed cars? My second questions is, so since the JB4 controls boost, does the flash control everything else such as, timing advance, afr, etc.. Also, if there was knock to be detected, would the flash or the JB4 reduce timing and how much timing can it actually reduce?

You should find answers to those questions in the open flash thread. This thead is re: JB4 firmware.

Just posted an interface update. The new interface date is 4/6/2015.

The changes are minor and have to do with time stamps in the logs. We found a little bug that could cause the timestamps to be inaccurate. e.g. it might put samples 80ms apart instead of 100ms apart, or the other way around, depending on how many data points the JB4 firmware version happened to be spitting out at the moment.

While not much of an issue it would throw off time to RPM calculations, etc, that I know some like to do within 3rd party software like virtual dyno.

So I fixed that and also setup the interface take the sampling rate from the JB4 firmware rather than being fixed at 10hz. So the interface can support up to 40hz now. Currently the JB4 firmware is still set at 10hz (even though some elements like boost, pedal, and fuel pressure are read at 200hz), but in the future we will be able to play with that sample rate output on the JB4 firmware side.

So far it's been stable so I expect to post 28.82 soon. If you want it sooner just email me. The only real difference between it and whats posted is map 7 when using a back end flash map.

It's more noticeable with the N20 sensor due to a smaller scaling value. You have to have a wider range of values for the N20 sensor and that causes a loss of resolution. Not a big deal though.
