XDF codes

[kelvin]

I'm looking for an XDF for a VN. There are lots of XDF's on here, but with number descriptions not car model types. What's the one for VN. Sorry, I'm new to this.
I've got an Ecotec in a VN rallycar running off the VN computer.

its probably a $5D
what is the broacast code of the memcal ( the 4 letter code on the delco sticker )?

I think someone has already had a go at this one. There is no window on the PROM , no chip type and it's maked "Marobi Stage 3". Can't find a Delco sticker on the memcal, but the computer box has a sticker with a 4 letter code AWUY, mean anything?. Anyway I can pick up another computer no troubles. Just need to know how you pick the XDF to suit the Computer.

the 4 letter code on the memcal (AWUY for example) is how you work out what one you need .... if you have a look at http://www.memcals.com/rcc_info_memcals.html

you will see that awuy is a $B1 code so you need to find a $B1 xdf for it....

having said that i wouldn't be so sure thats whats running in the car especially if you have a label like you mention on the eprom!

i think really you need to extract the code off the chip and upload it here and someone will be able to identify it for sure ....

Beautiful, that's what I needed. I'm sure it's all out there, just a case of finding it. Thanks.
But back to the eprom. So with no window, is it a eeprom or a once only prom, in which case would I need to replace it.

could be an eeprom or OTP one time programmable .marobi's are normally grossly rich read it off with a programmer if you can find a part number on the chip
