General How to tell if you have a EPROM ECU

[jamel16]

How can you tell if you have an eprom ecu ? What are the differences between eprom and non- eprom?

Pull the cover off the case, look for a chip.....if its there, you have an eprom. With an eprom ecu, you can get modded chips for whatever size injectors you have....and you can run dsmlink

Is that saying that a non-eprom ECU can be converted to a eprom ecu w/ the use of a daughterboard utilizing the microcontroller circled in green?

It says that, but the daughterboard when it was available was $700.

Ok, but now the new version of DSMLink for 1G's comes w/ a daughterboard included. Is this a different kind or does it not act the same as mentioned on TMO's site?

The board included in the 1G DSMLink setup isn't a "daughterboard" per se - they call it a "memory board" - basically all it is is a CPLD microchip w/flash memory on board to allow changes made to the configuration to be stored. You still have to have an EPROM ECU to be able to use it.
Just find an EPROM ECU on the trader or ebay. They can be had for about $300.

Ok I completely understand now, thanks for the help. However I find it to be major BS that a 1G 91-94 eprom ecu can't hardly be found for under $200. There was a LOT more 1G eproms made and that should make the price be relatively cheap on them, say $150 or less. If anything the 2G eprom which is only the 95 year, should be in the price range of $300 or more. Just think, 2G owners have a much smaller gap to find the ecu rather than a 1G owner. Ive personally serched every junkyard within 100 miles of me trying to find an eprom ecu but the only thing I have found have been 1.8L NT's and turbo automatics.

Let's put it this way. There are a heck more cars than there are EPROM ECUs to go around regardless of generation. If anything the prices for working 1G EPROM ECUs are going up due to demand.

It doesn't help that some number of 1G EPROMS ECUs are now trash because of the power supply failures caused by the bad capacitors, other voltage problems in our cars, and people who think they can solder. Right now I have six dead ones needing new CPUs or Port Expanders and a couple that people hacked to death trying to socket.
