Speed Sensor Signal Wire Location

[Karson]

Is the speed sensor signal wire the mythical "blue" wire discussed in detail for speedohealer and abs override switches?

Answered my own question, from nowhere other than Bazzaz (the competition). Love it when that happens!

Confirmed with Kenny from DynoJet that it is indeed the same wire as for the speedohealer. Did not ask how the PCV "learns" what gear its in, so I emailed them and awaiting an answer. Prepping for dyno day!

Nice.... cool new info !

Nope, but it gives me the option! - I want to setup individual gear maps when I get dyno tuned. Might as well try and get as precise as possible while I'm in there ::008:: I'm contemplating hooking up the analog port of the PCV to the coolant temp sensor wire going into the ECU. I'm not 100% sure what wire that is, but I think it's a Green/White wire - I'm not a very good schematic reader

Right now, my AutoTune is delayed by 300 seconds, whereas with this coolant wire tapped, I could delay it until it reaches normal operating temperature, as well as have correct AFR values for a range of engine operating temperatures. Be interesting to see how fueling is affected.

I like it!

You are off pioneering, trying to do REAL tuning.

I'm curious to see how the fueling changes with the different gears. This is one thing Yamaha did NOT do in the ECU. Timing, on the other hand, IS varied by gear.

IMO the best place to tap into that famous blue wire is at the ABS plug. You can unplug the large plug from the ABS thingy and peel back the sheathing for about a foot and have plenty of wire to tap into. The sheathing around the wires is peel and stick stuff and you can tap into a wire there and later undo the tap in and no one would be the wiser.

Thanks guys, kinda going in this with my fingers crossed ::008:: The blue wire at the ABS pump was another option in one of the speedohealer threads. Looks to be easier access.

I'll lift the tank again and tap into that if I can figure out the coolant temp sensor wire, too. I want to find a better tap location for that, as well. At least to see if my G/W color assumption is correct.

I really want to go into my dyno session 100% and get the most out of it as possible.

What type of dyno? How does the operator tune?

Good question, ac. I'm not 100% sure. I hope it's an eddy style, as opposed to an inertia style. Either way, I really don't have a lot of options, but will be sure to ask when i give them a call and schedule this hopefully early next week. maybe the coolant temp sensor idea won't be utilized during my tune session and will be a waste of time - will remember to ask him about that, too.

either way, sounds like lifting the tank for that will give me a good idea of its wire color ::008::

I'm also really curious what metering equipment he uses.

Most commonly you will find shops with the whole Dynojet setup. It is basically a package deal with the dyno, and O2 sensor and software that directly writes PCV maps. It's quick, cheap and they have a great sales staff.

Unfortunately, that isn't necessarily the "best" way to get things done. The main limitation is that this setup is pretty darn good at WOT and not very good at anything else.

Unless you stumble on a really good "tuner" rather than just a guy who "took the training", I wouldn't expect much from part throttle improvement.

An eddy current with a 4-gas analyzer and a true, "tuner" is what you would find in an ideal world. Someone who understands that tuning by AFR is NOT necessarily the best way. The dyno should also be able to set an rpm/tps and load the bike steady and long enough to get GOOD readings from the metering equipment so the tuner can make proper adjustments.

Once you've seen it done, by a true professional with the right equipment it is eye-opening.

Wayne Tripp at Power-Tripp is one of those guys.

We actually rode all the way from NJ to his shop in AL for his expertise and it was worth the ride!

I gave up on the speed sensor config on the PCV last night. I have no doubt it's possible, and may decide to investigate it further down the road. I actually posi-tapped into the blue wire near the ABS pump - the one with off brown dashes. Only to find out that this one had a solid black line on it, too. Sumbitch. No wonder I wasn't getting any voltage on the PCV software.

So, I lift the tank again and ponder why I'm doing this. It's about 9:30 at night. I went ahead and tapped into the correct one, I think, that doesn't have the solid black line. Then, ultimately pulled the wire off and said to hell with it.

Gear maps are cool, but I struggled with what it would benefit me. Maybe I'm missing something. To me, it just seemed like another added complexity to the bike that if something isn't right, I'd have to start chasing my tail to figure out.

I feel like a properly tuned single base map should get me 99% of where I'm hoping to get out of the bike tuning wise.

Anyway, the dyno (Iif I remember right is a 250i eddy) is having work done to it till Wednesday. I have till tomorrow to convince myself otherwise of the benefit of the speed/gear config.

Some good info on the process:

I wouldn't fret. Yamaha had essentially all of the time and resources in the world to develop the fueling maps and they chose not to do gear based fueling.

Quitter.

So, there IS a limit to your gearheadnerdyness?

I am I think if there was any benefit to be had with my setup at all, it would be to have a dual channel Autotune (AT-300). One O2 sensor/cylinder and tune that way.

At any rate, I think I was just spinning my wheels trying to tune per gear. I'm sure there's a more obvious benefit in other niche bike segments, just not the 600lb adventure tractor market.

I'm taking the easy way out, I know. I deserve to catch some flak ::008::

 

[snakebitten]

Lol. Really, no need to explain. I just enjoyed finding out there is a foot pound of torque out there somewhere that you just don't want that bad.

Bet it is still gonna torture you. In fact, I bet you revisit this someday. Probably when it's 25F and you have nothing to do but change diapers and watch Dancing With the Stars.

That was Yamaha's decision also...

Yep, I've succumbed to the truth that somewhere, somebody's grass is always greener. I'll just water mine and stick with what I have ;D

Yep I read that there were some slight timing (and fueling?) delta's between cyl 1 and cyl 2 in a few of your posts. I jumped into the game before the AT-300 was thoroughly researched on the S10, or in other bikes, and when I was first getting into the PCV + AT game. No regrets on the AT-200, though, but no doubt from a tuning perspective the more precision available, the better the tune. I would think that with our P-twin the heat concerns present with a V-twin motor wouldn't be as big of a factor.

I'm not too worried about losing that last little bit of precision, but no doubt tip my hat to folks that do. Getting late into the game at this point, the bike will neeever be perfect, but in a week that mindset might change. Farkling is getting long in the tooth. More of a chore taking that right side fairing off than it is fun

 

[avc8130]

That's odd, I am having the exact OPPOSITE problem. I've been running out of things to modify with the bike. I've caught myself going astray and shopping for another project!

Sickos.

There are roads out there I haven't explored. Sunsets\sunrises to be seen. Variations of coffee to be made with my Jetboil. And last but not least, laughs and stories with my soulmate at night, in the tent, on that big fat air-mattress. (While it rains on the fly)

Don't need a new weapon. The Tenere is perfect. Just like it is.
