Hello Everyone am just new here to the ZX14 world, I have a friend who bought a ZX14 2016 and the engine in it is from 2012, the problem that the gear position sensor (GPS) from the 2012 is not the same in the 2016 so the bike actually have 2 GPS one in the engine 2012 and another one outside from the 2016 which you can turn it by your finger to change the gears and get also neutral,

My question is, there is any how to fit the 2016 sensor in the 2012 engine to let the ECU areas all the shifts and all the map for each gear, or there is no way for such thing, and there is any way to clear all the codes what’s shows up after swapping the engines??

Thank you in advance, any help will be appreciated

I'm sure Hub or somebody will be here soon to give you some info on this. It sounds like what your friend might need to do is get a 2012 ECU on the bike so it will be compatible with the 2012 GPS. There may be other sensors on the 2012 engine that also are not compatible with the 2016 ECU. You probably have already considered all of that. Hopefully there will be a way to get all the parts you currently have working together properly.

These are designed totally different from each other so it's not even close to retro. Both faces at the end of the drums are engineered, meaning, one is spring(s) and plunger(s) cast into the drum, and the '016 uses a screw to thread into the end of the drum.

However, the 3 wires match at the gps so I don't think it would code wired correctly.
Light green = goes to dash or N wire at the dash.
G/R = wire to the ECU
Blk = To ground or to the blk/y wire.

Code 25 is the gps. Any other codes on the dash let us know.

thnx Hub for your reply, i have codes
11
12
14
16
24
25
27
31
32
61
67
so what i understood that there is no way to run 1 GPS i have to keep both of them connected?
i also want to ask if i can connect from the wireharness directly to the 2012 GPS and the ECU will read directly from it, i mean just to cut the coonector from the harness and the connector from the 2012 GPS and connect the directly so the ECU will read what gear the GPS on it inside the engine directly

thnx for help

It's more you make a tang depressing tool and move the pins out of the connectors. Then use the same gps connector for the main harness to match the plug connectors back again. They might use the same pins, but the connectors are different, yes?

That's why I mod outside the OEM. So, it's better if you go to an electronics store, buy the male or female pins [close enough], a spool of wire and make a homemade wire sub-plug. I use a dab of goop glue to hold and separate the pins from collapsing on each other.

Never mod the OEM FI parts or wires if you can. Those are phantom codes that popped up. 61, for one, is not in either manual so are we a non-western model? I'm assuming the bike runs without the gps connected, plus, that's the only issue, meaning, everything else is hooked up to the engine.

The bike is running perfectly without any problems the connectors are not the same but am not sure about the pins if they are the same or not all the other connectors are fine, he bought the bike from USA so it’s not EU, for example the only problem is if the GPS out of the engine is not in nutral the bike won’t start plus also am sure the the ECU is running on one fuel and ignition map all the gears coz he is not changing the gear from the GPS which is connected to the ECU and I think this the main problem now coz he is a drag racer

Locked to one map for all gears can be a plus. You only need to tune one map and it provides optimum performance no matter what gear you're in. The problem would be timing adjustments. If you don't know what gear map you're locked in, you won't know how to safely adjust timing. I'll bet the bike is locked in the Neutral map. If so, the timing is probably not restricted at all. The flies are also probably open all the time in the Neutral map.

thanks Rook for your reply, all the gears are unify from 1 to 6 and the flies are already removed, now he just start the bike on Neutral and the he move the 2016 GPS with his finger which is outside the bike already to the 1st gear and he run on it, but i am sure that there is somehow to let everything to work how it should be from the GPS inside the engine, but am still trying to figure how to do it... i am waiting to check if the pins in the connectors are the same so i will try to switch them but if not, i am still open to try everything to let the bike run with only 1 GPS

please if you have more ideas let me know

I think the bypass is to pull the clutch lever in. Wiring is setup to the kill/N/Clutch/kickstand... so basically, in gear, no start with N not showing, no start with side stand down and in gear.

am afraid i didnt get what you mean Hub, but if the GPS is in any gear the bike wont start without pulling the clutch in and if the side stand is down the bike will not start at all

one more question i have a friend who have ZX14 2014 which have the same engine installed in the ZX14 20016 can i try to swap the ECU to see if all the codes will disappear or the ECU will not work already?

... the only problem is if the GPS out of the engine is not in nutral the bike won’t start

I need to figure this one out.

... if the GPS is in any gear the bike wont start without pulling the clutch in and if the side stand is down the bike will not start at all

If the gps is hooked up, meaning, no codes, and snows no N in the dash, only then can you pull the clutch for it to start. Once you let the clutch out and is in gear, the bike stalls; only then by looking down and seeing [how many times I did this] is to see the stand still down.

... can i try to swap the ECU to see if all the codes will disappear

No. Two different animals. I have a 2017 and the code remains on for so many key turns. See what happens down the road and they might clear being all phantom codes, sans the gps. Make up 3 remote wires with male/female pins and hook those back up to the main harness and maybe all colds clear.
