Diving into the ZX-10 ECU


Supra sent me a ZX-10 ECU  (21175-0050) to play with.

This is a Mitsubishi product and when I opened it up I was able to identify the CPU as a MH8206F which is an Hitachi part the same as an SH7052.

This is a well known and documented Hitachi CPU that is used in the Mitsubishi Lancer EVO 7 / 8 cars. The openecu.org forum knows this chip very well.

Now the bad news. They all program their chips from the main connectors via an industry standard port known as an OBD port. The $64,000 question is did they run the OBD port to a couple of 'Unused' pins on the main connectors.

I found on the ZX-12 that the ECU was designed with a serial port wired to a couple of 'unused' pins on the main connectors but that the resistors and transistors between the CPU and the pins had not been installed when the board was manufactured. My big fear is that I will find the same thing here. Is that the difference between a KIT ECU and a stock one? Both are wired for programming but only the KIT ecu has the necessary parts installed? That would suck

On the ZX-12 they disabled the serial port but left a Background Debugging Mode or BDM port on the back edge of the board. Buy just exposing that connector I am able to flash the CPU through what I now refer to as the Back Door Mode port. This Hitachi CPU has a similar development port called an AUD port. I tried to find an off the shelf interface for an AUD port back in may for a guy in the ZX-6 forum with no luck. the only one I found was from Hitachi and cost $2000

Anyway until I expose the rest of the board I'm just theorizing. Time will tell.  Stay tuned

under the hood of a 21175-0050


It reads MH8206F

I think your going to find the ease with which you were able to hack the TLR will not apply to the ZX-10. While it is the same part used in the 32bit Busa and ZX-6 and I have no doubt it can be reflashed thru the harness (not proven yet) the problem is that unlike the ecus above it has no AUD port to read out the code.

At this point it looks like you would have to remove the CPU and put it into an eprom burner rig and read it directly. Maybe you could identify the AUD port pins and solder into them instead but either way it is not going to be fun.

BTW be careful removing the potting around the cpu. Unlike your TLR there is no hard epoxy around the cpu pins to protect them. If your not careful you will rip them right off the cpu.

Here are some pics.

does the kawasaki workshop software allow any map changes, can you change for octane level !!
also how can you get around the imobalizer

does anyone have a link to the kawasaki software

many thanks

Hi guys. I'm new to this board and I just got an Extra zx-10r ECM. I was wondering if anyone is still working on this project. I have an 05 zx-10r, but the extra ECM is from an 06. would anything I can learn from the 06 apply?

thanks in advance

I got interested in this process because I had a free ECM to work with. I may still be interested in trying and possibly in buying a 2005 ECM. I just looked at the 2006 compared to 2005 and it is completely different. I even saw somehwere it may be a 64 bit system. But I lack the skill set to start from scratch. And it looks like there hasn't been a whole lot of developement done with these, because of the missing AUD port. I would like to know if the busa developed maps would work as a starting point on this system so I could skip trying to get the base map? Maybe someone has compared some of the other 32 bit base maps like the busa to the zx-6r to see how close they are?

That idea is a non starter. When you reflash the maps you have to reflash the entire flash area; code and maps. There is absolutely no way your going to get anywhere flashing the code from one bikes ECU into another.

I just picked up an 04' race ecu. i was wondering if the RS232 converter used for the bikes on this site should work to program this ecu? in the Kawasaki FI software it is called an RS232 connection. I really don't want to spend $400 for the Kawasaki cable(part number 26031-0025). Also I was wondering how hard it would be to Rewrite or modify the maps and software? there are features for the 05' race ecu which I would like to program into the 04', such as, increased rev limiter, quick shifter and increased frequency of fueling and ignition timing points (say going from every 1000 rpm to 250 rpm). I saw in other parts of the forum there were people that are familiar with this family of products. any help is appreciated.

humm i have a skematic of the kit ECU wireing harness and how the computer hooks up to it. It flashes through the harness with the kawasaki software.

Would this help anyone? and ill post them up.

I'd love to see a schematic of the Kit ECU interface cable (26031-0025). These things go for $500+ and I suspect they are a simple TTL - Serial converter. Does anyone have one that they can open up and post pics?

Since it has been hacked or is in early stages. Can you point us in a direction so maybe we can play with it? Not asking for your research for free but maybe point us in a direction so we can get some heads together? I would love to see secondary throttle adjustments, Exhaust servo delete.

I'm guessing its flashed through the harness like the race ecu? I have the pin out from the race ecu to harness will it flash to the stock ecu the same way?

From what i can tell from the schematics. There are no pin #'s listed but Pin 22 is involved, The BK\y wire is GROUND, R\Y = SIL, O= TS, W\Y=+b. This is from the main harness to the ecu. Also the diagnostic plug is used also. I have the schematics but it does not show much.

The Kawasaki part # 26031-0244 is the interface adaptor cable that connects the pins to the kawasaki adaptor, It seems that is just a TTL to 232 converter. This is all for the kit Ecu that is adjustable. But it might work.

I really want a DIY option for the zx10 but i know nothing about programming. IF I buy the cable and figure out the pins does anyone think they can help me out and walk me through changing some stuff?

Also i was talking to a guy on zx10r net(he might be a member here also) He said he could ship the ecu off to Italy and they could make the std ecu into the Race ecu and it would use the Kawasaki software to make changes just like the race ecu. I have no problem opening her up and doing some soldering if that is all it takes. Anyone know about this?
