I just bought a boondocker nitrous kit from Justin at Code Red, do you happen to have any base line numbers for tuning? I run anywhere from 0ft to 4000ft.
Also I was thinking of maybe getting a o2 gauge to help with tuning. What brand and where would you recommned where to get it.
TTT
Or would duel EGT gauges work
Either an o2 or EGT can be effective in tuning. My opinion is an o2 is easier to use, but EGTs seem to be more reliable.
If you’re running an adjustable regulator Dragons seem to be tuning in at 16 at 180 and 38 at 340, in the nitrous screen.
i have an o6 crossfire 7 which i have extended to a 153 i have recently bought jaws twins and i cant get them tuned in for minnesota wisconsn just woundering if you had any tips
I don’t have any starting numbers for you, but early on in this thread we discussed tuning with twins on M7-8s. There are a number of different features in the BD box that are commonly ignored that can make a huge difference. Review the first few pages of this thread and let me know if there is any info I could add that may be more helpful.
When i let off ofter a long pull my A/F number go through the roof. Would adding a little bit on the low mid help this? Thanks for the help.

Yeah… adding fuel in the lo and mid will help this. But I wouldn’t add fuel in these areas unless you absolutely need it, because it can case you to load up.
Junior, I posted this in the AC section. (Couldn't find this thread last night)
I have my BD box on basically a bone stock 07 M1000. I have the fuel pressure set at 42psi (BMP regulator). I have the BD box setup to keep my EGT's in the 1150-1200 range through out the RPM range and at all throttle settings. This works well at 6000ft and up. When riding lower elevations at a steady throttle setting around 5400rpm in the low tps I will have the Mag cylinder drop out. I will see a good 400 deg difference in EGT temps. If I nail the throttle it will snap right up and pull hard. (Sometimes not but 90% of the time it will clean right up).
I am wondering if the ECU is compensating the fuel to the point that it is running rich and causing it to foul due to the lower elevations. I have copied my 6000ft fuel map and tried to adjust the fuel. I have to add a couple points to keep the temps below 1250 but then it wants to foul when I get out of it. Pulls hard, snap off the throttle and it will foul.
Any ideas. I plan to call BD tomorrow and talk about it but thought I would try the SW guys first.
Thanks

Sounds like you could take some fuel out of the 5000 mid, you can also use the TR in the 5000 to control fuel on the PTO cylinder.
Check out your stats screen when you’re having the rich condition, to see what rpm and load range you need to adjust. You could also use a capture button to freeze the stats at any given point, and review the info after you’ve come to a stop. The left arrow button can also be used as a capture button, if don’t have a nitrous/capture button.
i have a 05 f7 lake race ported .pipe and bd box,im putting a air fuel ratio guage on it this week,my dealer told me fuel pressure should be 46 and a/f guage set at 12.2 is this correct
46 psi sounds good to me. I usually try to hit mid 13s on a NA engine, but that could be too lean for your application. If your dealer has experience with this specific setup I would definitely heed his advice.
Thanks for all the questions,
Junior
