ECU upgrade for the zx-14
I am building a test stand to fire up and heat cycle zx14 engines. I can also use the test stand to do some of the testing when I get the Megasquirt boards in. But while I am waiting on that , I decided to try using the zx-10 ECU and wiring harness to run the zx-14 engine. so far everything is looking pretty easy since the 10 and 14 both use alot of the same sensors.
If the zx-10 ECU works I will have a higher redline and maybe a more aggressive timing map. But it also means that the the factory adjustable ZX-10 race ECU will also work. That might be a simpler option than building a megasquirt for some people.
the only thing I am currently missing is the zx-10 gauges. I have zx-10 ecu , complete wiring harness, throttle bodies and harness, and harness for the coils.

quick update.
I looked at the pinouts on the zx-14 and zx-10 ECUs and they were nearly identical. the zx-10 doesnt have the canbus , and the zx-14 does have the exhaust butterfy. but those pins are unused on the ECUs that doesnt support them.
so I plugged the zx-10 ecu in my '06 race bike , AND IT FIRED UP !!!!
I was running very rich but this means that the zx10 adjustable ecu should work on the zx-14. the only thing missing is the wires for the zx10 gauges.

Yes, that is the cat's meow you run the kit-ECU. But here is the deal. I have your same setup, plus a kit-ECU and a 600 wire harness. The 1000 wire harness has to match the kit-ECU. There is an adapter to read that kit-ECU, change maps, you need that cable too. And that connector from ECU to its software to the laptop is worth about 500 bucks to make the kit-ECU work at all. Luckily, I have access to borrow that cable once I wire up the kit-ECU.
But without that com-cable, you are stuck with an ECU needing a timing change:
ZX-600 ~ 12.5° BTDC
ZX-1000 ~ 10° BTDC
ZX-14 ~ 10° BTDC
I have a borrowed gen1 14 ECU with my old gen1 throttle bodies. I have the 1000 injectors in the gen1 throttle bodies now waiting for a swap to see if the 1000 injectors are rich or lean? Therefore, I have 3 injector body sizes to choose from. You should swap the 1000 injectors and see what the A/F will do now to the 14. The ignition is nothing to worry about. Like you said, just the curve will be different is my guess as I agree, it might be somewhat aggressive.
I had to swap the 1000 harness wires to the 600 ECU prong readouts. I do not know what setup you will need between the 1000 and 14. I think the ECU female plastic connector ends do not work but one. Lay both ECU's together to see watt I mean. So yes, I would have to rewire the 1000 ECU harness married to a 14, as in the direction you are about to try. But I am heading in the 600/1000 direction, not the 1000/14 try and see what might happen in that direction?
We are looking at a 13 vs. 18 pin difference. Those are a lot of pins lost, you count both rows on the one side of the ECU. The other connector may plug in, but do they match line for line? And if anyone is going to make it work.. I'd count on you, sir.

How many codes popped up on the dash? Lean out a map or swap injectors. If you say really rich, I doubt you'll PC the lean out of it. If you can spike the map out of scale, it resets to full lean; that's if you can hack into it.

I just checked all the sensor info ,,, only difference is the speed sensor. the zx-14 uses 9-11v and the zx-10 uses 5 v ... different connector also

Are you guys giving up on reflashing the 14 ecu? I thought that software was under development?

i was never part of the reflashing .... I am waiting on a megasquirt3 to build an ecu.
But having the zx-10 ecu or the programable ecu for the zx-10 is an option right now

I know that right now they can definitely reflash rpm and speed limiters. The software looked similar to the Busa stuff.

Supposedly it will unlock all ecus are far as I know.... Until that time, I'm covered. I have the rev extend (500 rpm), power commander III usb, and the ignition module.

The last update I read they had only cracked the 06/07. But I may have missed the rest of the updates.
I purchased a extra 07 ECU and complete harness and 08 fuel pump. I need to read up on the module.
Thanks

Update is more a seen your moment: Here are the steps or wall I came up against. Since you are on top of it now, maybe you can find how to connect a certain problem between the 10 and the 14...
quote:
I looked at the pinouts on the zx-14 and zx-10 ECUs and they were nearly identical.
And then look at how many with their [own] weather-pac blanks not used, and who are they, what do they do, wink-wink.
quote:
the zx-10 doesnt have the canbus , and the zx-14 does have the exhaust butterfy.
I have a 10 throttle body with the same 14 subthrottle system.
quote:
but those pins are unused on the ECUs that doesnt support them.
Wink-Wink! RidgeRacer or Pat might know.
quote:
so I plugged the zx-10 ecu in my '06 race bike , AND IT FIRED UP !!!!
I'm sure it did with that throttle body main wire harness connecting right up, all wires match... Now here comes the wall...
quote:
I was running very rich but this means that the zx10 adjustable ecu should work on the zx-14.
You may need to T-off on a new connect, that will run off the flex fuel line. You might have an 8-injector system. The 10 wire harness and ECU I have, has the 8 injector throttle body.
Good luck in the wink-wink dept., you find the blank pin that pins out like the 14's 4 injectors? I wish! First year 10's come out with 8 injectors? What year are the injectors? That will tell you the year of the bike. How to determine the year of the bike; the injector was made for that production run for the following year. Said another way, if you have an '06 14, the injectors were made in 2005. If you have an '08 10 throttle body, the injectors should read 2007 and so forth.
EAT 287 should be on the 10's injector body. Then on the other side, you will see the year 08 or 07. Mine read: 28707. The ECU/harness/t-body I have is for an 8-injector 2008 ZX-10.

I am about to send my 08 zx14 ECU to:
Guhl motors
4126 Oregon Pike
Rear Building
Ephrata, PA 17522
to have them flash it..$375...ouch..
Anyone have any experience with full timing in every gear and revving it up to 12k?..my motor has HD valve springs..

Doing alot of traveling and havent gotten my ECU out yet. But on another note i talked to lil sal@ ace performance and he will get my ECU instead (prolly cause he will ship it to Guhl anyway)

Is this option to flash the stock ZX14 ECU ever going to be available??
I am thinking of going to a stand alone ecu but would rather stick with the stock one if it can be made fully adjustable.
Any news? Anyone?

Some people have given up and are just putting a 08 Busa ECU on the zx14 and that allows you to flash and tune everything
