Brozz 250 Speedo Correction using SpeedoDRD

JohnC · 11-09-2020, 03:10 PM

I had a conversation with 12oclocklabs. Sent them pictures of the connections on the Brozz. Turns out the connectors are the same as for the Honda Code H1. But the wires need to be re-pinned. If you get the H1 unit, to make it work change the wires on the Speedodrd unit.

On the connector to the Speed Sensor side, switch the red and white wires. (These are male connectors.) On the gage side connector of the Speedodrd unit, switch the red and blue wires. (These are female connectors.)

In order to get connectors loose to come out of the connector, you have to squeeze little tabs that hold the metal connectors in the plastic. Need good eyes to see the tabs.

Once you switch the wires on both connectors on the Speedodrd unit, they will plug right into the Brozz speed sensor and gage. Just like it was made for it.

The H1 is what i just installed on my Venom Ghost. I only had to swap the white and blue signal wires as they were reversed. I think the H1 will fit most of these China bikes. Yu will just have to verify the proper pin out but at lease the connectors are the same.

Ok I got the H1 in the mail today but for some reason it’s definitely not working as intended. I determined that my speedometer reads 5 high at 60. I flipped the red and white wires on the one speedodrd connector as mentioned and the double red either the blue.

I found I need a -8.30 from the calculator in their website.

After printing out the instructions I programmed it as indicated but am getting random numbers on the speedometer when moving, especially seeing 199 but lots of other numbers too. Thoughts? Wanted to ask as you have done this successfully. Thanks.

Reset it back to factory settings and start over. If you mess up while setting up it will be damn near impossible to calibrate. I know on my X22R i had kind of the same issue. Once i reset it and started over it worked perfect.

Hmm reset and reprogram the same thing. Random numbers and lots of 199.

Reset I followed for v4 (confirmed I have v4)

hold 10 red blinks then release.
fast red/green
hold, then release after color cycle to green.
then red/yellow (orange as indicated) then leds shut off.

then ign off then back on. hold 5 red, then hold until red led then release.
hold 10 red blinks
hold red 8
hold red 3.

-8.3 correction.

I didn't use the calculator on the web site. I used the formula for GPS calculation. Try calculating it that way and try again.

Using the Speed of a GPS device the formula is:
Correction Percentage = ((GPS Speed / Speedometer Readout) * 100) – 100.

I have no idea then. Using that I get 9.09

With it still inline I did a factory reset and drove forward a bit and got wildly fluctuating numbers which I also got using 9.09 (both negative percent and positive just for fun)

I started having that issue with my Speedodrd. When starting the bike, the speed would go crazy, 3 digit numbers flashing as fast as it could go. Of course adding miles on the OD as well. It would stop if I moved the bike around, most of the time, else I would shut it down. I talked to the company support and he pretty much gave me the, it's a chinese bike electrical noise issue. He suggested a capacitor in the circuit might clean it up.

Anyway, I have it off now. I'm not sure what to do with it.

I was looking at the digital cluster that Stewbrash purchased because the wheel diameter can be programmed. Which I think is likely the problem all along. I think there might be a link here somewhere, but haven't found it yet.
