The Moates Ostrich 2.0 is an 8 bit emulator (it can emulate 27C256 EPROMs) and it cannot read or program chips. Hello again, I have since bought a cheap programmer and successfully programmed a blank chip, unfortunately it isn't electronically erasable but that's besides the point. This screenshot ...

The ECU cannot tell the difference between an EPROM and an EEPROM as it is only the method of programming that differs when it comes to using the chip. Awesome thank you!! And a Moates Ostrich 2 can programme and read 27C256 yeah? If so I'm all ready to go ahead buy the programmer, chips and blow u...

Emulation is when you use a device to emulate a ROM and allow real time changes to the calibration. It saves having to burn or reflash a chip every time you want to make a change to the calibration and try it out. Personally I would replace the EPROM with an EEPROM to simplify matters by avoiding h...

If you are using a 27C256 then you will need a UV eraser too. The datasheet for the chip you are using will give the erase specification you will need to select a suitable eraser. Several different Willem programmers will work, there are also the inevitable Chinese knock offs that are cheaper. A Mo...

I think we are looking for a programmer for: 27C256 type, a 28-pin DIL (Dual In-line) chip. It contains 256K-bits of CMOS memory At least that's what I need for my '87 BMW 325 (E30). Mine's a 1990 320 and I actually have a 'mild' chip from the e30zone that I bought so also want to be able to read t...

Yes, exactly as Tinkerer007 said above.

Also thanks for responding, I would have put that information in the original post if I knew it was crucial info.

Hello all,

I am getting in to tuning and need an emulator/reader/programmer to erase and write my new maps for a 28-pin EPROM chip for Motronic 1.3.

Does anyone have suggestions for a good one to buy and where from? I am in the UK if that helps.


Thanks
