For the past couple year's I've been working on and off trying to hack into the gen 1 ecu so we can have a DIY flash option instead of having to pay $400.

Well we have SUCESS! I have connected to the Ecu and been able to read the stock .bin(File that contains all fuel maps, rev limints, ect) From the ecu. Now we can take that file and change the fuel maps, timing ect and flash it back to the ecu.

This ecu and all the other gens also use what is called K-line flashing, So you will need a hardware interface that can flash to the k-line of the ecu. There are several on the market

Here is a china clone of an interface that will work if you get a good one. They seem to be 50/50 hit or miss but cheap so buy 2.

Here is the pin out for the Gen 1 ecu




and here is the stock .BIN file.

Now this is where my experience gets thin. Hopefully some zx10r members here can help with this, we haft to decode the file and indentify what maps are what so we can make changes and flash them back to the ecu.

I plan to do and how to with several moded maps so you can just pick one and flash it in the future.

Also thank you to johns04r1 he helped me get all this togeather.

I can read and write to one, That is a denso ecu correct? I don't have one here to test though. i will extract the bin file and post it up if someone wants to send one.

The hardest part is decoding the bin file and identifying the maps and that is where my experience ends. I'm working on learning that side of it. But once its defined its no problem to make any changes you want. Johns04zx10 is working on the zx10 now, but i wont be a lot of help there.

The main thing im after are Rev liminters, secondary maps, timing curves, and delete the F1 light for exhaust servo. And other stuff like that. Fuel maps are best left for your tuner with a dyno,

But once we get everything defined dyno test would be great.

Said like a person that knows what he is talking about!!!

I talked to Don Guhl about reflashing my 05' and he said the Gen1 aren't restricted very much at all. Then mentioned he could raise the rev limiter and a few other things.

REP SENT>>> I'll be watching this thread. I have a Gen1 and Gen3 in the waiting line....

Still digging through the assembly code. This might take some time.
