The 0xygen sensor is # 32 on ECM The mass flow or MAP=TMAP is ,I think one of these wires # 3 #9 #21 #10 #25 or#13 #15 #31 or #33? Anybody know what Honda calls this sensor on schematic?

I believe it is from pin 3 on ECM which would be the yellow wire from the 5 pin/wire harness on intake. I am going to go look at bike now.

welp, theres the map sensor,
this should be interesting.

Is that it?

I want to be sure.And I prefer not to remove the two modules to see which one has the heating elements. It would be a little more trouble as opposed to very simple to do it discreetly and very,very easily done in manner it could be hidden or removed. Once installed ,it's mine,no returns.

I am looking at bike and I see two components on throttle body. Does it have a MAP and a MAF sensor? The instructions I got with the chip say to wire in parallel to the IAT sensor which is a stand alone component or part of the MAF, /MAP- TMAP sensor on intake. I am not ,getting much from schematic and even if I figure out what wire is what ,I am not sure how to apply that to this bike with the schematics in front of me,due to the unfamiliar terminology utilized. I am a complete novice at this, and I do not seem to be able to reach tech support. magnumtuning.com/contact_en. WTF? HELP Mr. WIZARD ! a cartoon from my youth. Say it all the time.

Thanks again! I need to see where blu/white wire from SENSOR UNIT, a 5 pin plug goes to. It is one component away from the 1ACV which is a
4 pin plug next to the ECM. Would you take a picture that includes those two components in and the ECM in one complete picture
Thank you. I am having to learn this stuff ,but it isn't difficult,it is just different.Also I need a picture where the W/Blu wire goes to from the SENSOR
goes to in one picture if possible. It is on SENSOR UNIT as TA VOC I will buy a manual asap. Hope I don't need one Thank you for your effort,
I appreciate it.

Ultimately, it is the IAT that I am supposed to access, if a MAP ,or MAF, or TMAP or combination of both, that is the reference that is utilized. Now to try and de-code the schematic that I do not actually possess.As well as learn Japanese translation of/ explanation, per schematic that I do not actually have.
SHIT! I will be able to design one of these things for any EFI by the time I get this figured out. But I know I could use some help. If not cold as ###!!! outside
I would never attempted to learn this SIMPLE shit. At least we will help others FREE THEMSELVES FROM THE STUPID SHIT! AMEN BROTHERS..
CARRY THE WORD ....

I don't know why I didn't think of this already,but I believe the best thing to do is buy a five pin harness with male and female ends and not have to splice into any factory wiring. I saw some 24 inch extension harnesses on amazon,and I could just plug up the Dyno-Boost and dial it in a lot easier if I didn't have to reach for it.
I bought this chip from what I believe is a middle man salesperson? thru PayPal. The hook was PayPal offered the guarantee that if I was not satisfied that they would take care of it. The instructions came with the e-mail addresses that were not complete ,hence I was unable to contact them. I contacted PayPal and informed them and was contacted by some Z -BOLT character who in My OPINION i,s neither knowledgeable of product nor truthful and I am tempted to send it back. I do believe
If installed properly ,and I am not satisfied that it should be returnable. It is not.I think this will work on any motorcycle with EFI and that wiring thru a harness extension will make it easy. It is adjustable,and with the little I have learned ,I am confident that I could make one out of individual components. Resistors,etc.

I probably won't due to the lack of response and inability to reach magnumtuning.com. I had to learn about this stuff. Basically a constant referance voil;tage is supplied along with input power . The output signal,, voltage from the sensor varies ,and with variant signals from other sensors,(O2, MAP, or others , depending on design ) lets the ECU (know what it needs to know) to maintain a constant AFR. It would only hurt it if it runs too lean. It has a variable resistor that you adjust to vary
the return signal to fool the ECU. Like sanding and refinishing wood floors, it is very simple,but there are a thousand ways to F it up. And at some point it would be starving for air or back pressure which would inhibit performance. I do believe that the manufacturers hands are tied somewhat ,to comply with emission regulations. CORKED UP ! I am going to get a different bike when able,but absolutely will keep this one as cheap insurance in case of SHTF scenarios. Bur damn, I am in a great location to ride back roads of some of the best riding in the world!

to know its right after installing... you need to throw a wideband sniffer on it and verify its actually doing something. I have one, so when i put the eife unit on mine, i knew it was right.

Thanks. I don't know what that is , but I agree . I should verify the correct wire is utilized as to function properly. I should be varying return signal ( milliamps ,if voltage is to remain constant, or varying voltage signal. I am ignorant as to what the logic being , but utilized. Analog would be easily done, but if is digital a special meter would be might be necessary O SCOPE, or GRAPH MULTI METER. Or better yet, what you are referring to. I will investigate this . THANKS!

FYT, This schematic does not match plug wire configuration on bike. I am wondering if this this for the super cub? Not what is on actual bike.

schematic does not match instructions or actual plug wire configuration on bike. One is incorrect.

I'll be honest, im not going to go much further until a decent standalone comes along, or an unlocked ecm. However, the 2022 monkey ecm should swap in and its rated for more HP, so im sure the tune is different. .02

I do not want to go over 50 mph, but I need to be able to for a few miles once and in a while.For where I have been riding, this would make this bike better than
any thing else. 125 miles yesterday thru Virginia Highlands. EPIC! Perfect weather,incredible scenery,and most important almost no traffic. Like NONE! Day of the week,time of day is important than whether bike could maintain 50 mph uphill or not. Actually more important.

all the stuff i did i can maintain over 55 pretty easy. Not much more, but that fine. just my .02
