Rhinoman do you have an electrical engineering degree?

BEng Electronics, University of Reading 1998. Before I went to Uni I was apprenticed as a Technician (HNC qualified), worked in R&D for a large Defence company. Since 98 I've been designing electronics for defence applications.
No one seems to be working on the Zuk ECU and there is almost no information on the net. I have a spare ECU so I thought I'd have a go. Then I can start looking at performance camshafts and stuff  ;D

so you work for the military  >:D >:D >:D

oh ya what did you do to get a turbo setup for the ecu?
and i was on ebay and there was a couple of chips for turbo and non turbo apps claiming 10 to 36 hp if any ones got a chip tell us

Hey Wild, good to hear from you. When I first started looking EFI a few years ago I knew nothing about it at all. You were the guy that got me started on all this.

The HC11 has had literally hundreds of variants over the years. IIRC the MS1 used a 68HC908. MS came out of the old GM ECU forum, originally they hacked the GM ECU which was HC11 based. Then they developed a 32 bit EFI which wasn't a great success, the guys behind MS thought that there would be a market for a simple stripped down ECU and developed MS - smart thinking.
The MH6211 in the Zuk ECU is more akin to the 68HC11K, the same 84 pin PLCC package but a completely different pin out. It also runs at 4MHz internally, twice as fast as the old HC11. However because the address and data buses are seperate its actually 4 times faster. The instruction set is similar to the HC11 but something like 30% of the instructions have different binary values. In addition there a few Mitsubishi custom instructions. All that means that the HC11 software tools can't be used, reprogramming must be done the old fashioned way - in hexadecimal.

There is a device that is used to reprogram 300zx ecu (pocket emulator to name one) that may work well for a final version of this, thus giving you the ability to drive and hack code


There are a few software packages about but I already have one that I developed for my own ECU. I will adapt that to suit.
I've put a few screen captures below. The gauges still need a bit of work, they were my first attempt at producing a Visual Component. One of the reasons for this project is that I use it to teach myself new skills. I also have back problems so it gives me something to do when I can't otherwise work on the truck (like now!)

I don't have a turbo setup. I think Wild used a progressive pressure fuel regulator with some success. One of those with a remapped ECU might work. As I said before, if I can crack this then it would open up a lot of possibilities.
Those chips are just a con.

i thought that they were a con. but keep up the excellent work and hey you could sell the program (after) and make some serious dough.

Wow :o :o I don't understand any of this! ??? ???  Is there an application to the Samurai hitachi or fuel injected or are those ecms too obsolete? If you figure these ecms out does that mean you'll be able to figure out the other makers ecms? How does this differ from P.L.C. programming?  -Adam

I've not seen an ECU for a Samurai so I've no idea how difficult one might be to reprogramme. A number of other ECUs have already been hacked, some are much easier as they use commercially available chips for which datasheets and tools are available. PLC = Programmable Logic Controller? the sort used for machine control? I've never had occasion to use one but as far as I understand they usually come with instructions.

Keep up the good work.  Looks like you are making some headway.  Can't wait to hear the results from your experimentation.
