Thread: Name that ECU!

/flamesuit/

I had bought this ECU as a calum b14 basic ECU. I am just wondering why does it have a db9 port coming out of it and why does it have two ZIF/chips on it? Two separate bins? Any information on this would be great.

Thanks,
Jake

The DB9 is a serial port interface for consult, which is nice because you don't have to have a separate consult adapter box. The 2 chips in the zif sockets contain the exact same bin. The reason is because the CPU in your ECU (and all other M37790 based ECUs) has a 16 bit data bus, and 16 bit EEPROM chips are like chicken teeth. You have 2 8bit chips so odd addressed bytes are read from one chip, and even addressed bytes are read from the other, simultaneously.

Thanks for the reply Dave. So I'm going to need two 8 bit chips with the same .bin on it? Is there anyone around here besides calum that can do is? Also is there a how-to on burning chips for these ECUs? I found a link to a burner but the link is old and does not contain that product anymore. Can you use any EEPROM burner for these chips? Thanks again for your help.

You can use the new MOATES burn 2 (I think that's what it's called?). It's backwards compatible with the MOATES burn 1.

When you burn the chips, you burn exactly as you had mentioned. Both chips receive the same .bin.

When looking at this stuff it just seems a bit intimidating. So when burning with this ECU, can I use the 16 bit chips or can I only use 8 bit chips?
