It did come with the fuel wires so Iíll hook those up.
Guess my last question would be what I am looking for when it comes to the logs?

Basics - Ign 1 is the most important item. Drops in timing indicate engine knock which is damaging to the engine. AFR should bottom out around 12. Watch for boost spikes during engine shifts and adjust boost target down to compensate near that RPM.

Hopefully more advanced users can chime in with more insight.

We don't have a Q50 specific how to read logs post but it's similar to the Stinger one.

Thanks for the replies, been helpful.
For now I just lowered the boost to +2
Gonna up to fuel octane then Iíll play around with the numbers
Another question, is it safe to assume i can raise the boost more if I add ldp and cbe as well as a cai?

Always modestly increase boost and log, don't just assume.

Stock Q50 RS
Fuel wires installed, Bit 0 enabled
WOT pulls showing some 10.5 AFR at 17.5 to 18 psi
Duty bias default at 50 (latest firmware hex9)
Question: Can someone explain Duty Bias? Can I use this to slightly lean AFR toward 12.0? If so, which direction should I adj bias?
Thanks in advance.
Bob

Duty bias is only impacted when EWG connectors are installed. Nothing is happening on your car with those numbers in the fields.

18psi is aggressive for a stock car, you may want to post some logs for review

Default AFR as low as 10.7 - 08-25-2020, 11:32 AM

Is it a problem if one or two readings of AFR during a pull are as low as 10.7?
What about IGN2 and IGN6 showing all zeroes?

Your fuel wires do not look like they are active in the log. You would likely not fall below 11.5 or so if the wires were active and working. Ign 1 is the only active log for timing, so no worries that the others show zero. Fuelen column would show values at higher RPM if it were working properly.

Thanks. I actually do NOT have fuel wires. So can I assume that everything else looks relatively normal?

Yes, the fuel wires will even out your AFR - not critical, but makes a bit more top end power. The timing looks normal, but you may want to do a log/pull of 2nd gear to redline then to 3rd gear to 6500 or so. Looking to make sure the timing recovers after the shift and then stays say between 6 and 12 without any single large drops. At the shift the timing will normally go to zero.

The factory mapping will dip AFR in to the 10s during runs, which is where the fuel wires are useful to lean that out for more power. Only IGN1 is active. The other parameters have non-related data stuffed in them for diagnostics.

Is there a way to get all default Values to Start Fresh; Is there a Button on app to set all back to default? Can it be done by installing a new Firmware?

I will be Installing mine this upcoming weekend; Once install will enable Fuel and egw settings , then Map One and Datalog it. I will like the JB4 witch was bough used to get back to Default Values and Start fresh with my RS400 and JB4 experience...

There is not a reset button. Default settings are included in the first post.

Hi, Im very new to this platform and was trying to get a opinion on my data logs. The car felt really sluggish on the launch at the track. My afr was pretty lean on launch. Here is my data log. Thanks.

Terry please check this log. Looking for ideas how to launch in boost or get boost in quicker. Since you have wastegate control and fuel control have you investigated a launch mode? I've got a significant chance at 11s in good weather but need to leave in boost.

Looks generally OK to me, you may need to brake boost more aggressively to get a better launch going. The high RPM map6 taper isn't doing you any favors in 1st gear either.

On launching what works best is brake boosting as aggressively as possible. Let it sit in brake boost for a few seconds to spool up.
