Any electrical engineers here?

[Killer223]

Have some things I need to double check by and EE, me being an ME I know some, but not enough.

We have one here, but I won't call him out.
Jot down what you want to do, a few of us are smart enough with these machines to help you accomplish what you want.

I'm no engineer, but I do know my way around Honda electrical systems a bit.

May be able to assist.

Sounds like a challenge!!!

The gas pedal increases voltage the more one presses it. I’d like to wire a switch and resistor inline to reduce the sensitivity of said action. Switch could be normal, and eco or reduced power or something. I’m willing to do the R&D on it to get the correct resistor. I need to know a wording diagram, and any thoughts on this.
I’m not interested in bringing this to market but I’m sure it’s be a good seller.
I helped design similar items for the second gen dodge Cummins trucks. With a high idle mod.
Anyhow.
Thoughts?

So your wanting to alternate how much pushing the pedal tells the TPS it's actually moving?

The P1K also has a throttle pedal sensor, so youd have to do something with that as well. I think their referencing the Pedal sensor to determine if the throttle angle at the TPS is correct.

Honda does this on their electronic throttle models but they have full control over the amount the throttle turns since there is no physical connection between your hand and the throttle body.

Kinda yes. By adding a resistor inline on the signal wire, the ecu wouldn’t know your at 1/2 throttle only 1/4. And say full throttle would only be 1/2.
I know the drive by wire systems are great. And this could maybe be achieved via tuning. But I’m not wanting to spend 1200$ for the software and hardware to find out the option isn’t there. Where with the resistor on the signal line could achieve the same result.

The talon has a throttle cable, its not drive by wire. The only way to desensitize the throttle would be by mechanical means. If it's anything like the pioneer, once broke in and fluids changed, it gets smoother.

So does every Honda SXS, I'm trying to wrap my head around this to see if ita possible. But I don't think it will be with the physical connection present.

If it could be done you would need to match the pedal sensor with it as well. Like I said I think their using it as a check/balance for the TPS.

If the throttle blades are manually open 20% and you trick the TPS into thinking it is at 10%, you are getting 20% air and only 10% of the fuel required and would be extremely lean. It would have to be a drive by wire to change it electrically.

One thing used on motorcycles is a cam shaped cable guide on the throttle tube. The initial diameter is small where the throttle wraps and gets bigger as you turn it to pull the cable faster.

Also some older skidoo snowmobiles used a 2 stage throttle where the pivot point “pin” rode in a slot against a cam so the first 1/4 throttle was very smooth and the last 3/4 was directly connected to movement.



Seems like the gas pedal pivot could be modified to achieve a similar result.
