-ECMLink ​is released as an EPROM replacement device. ​ That means in order to run ECMLink in your ECUyou must have an EPROM model ECU.+**EPROM ECU:​** ​ To run ECMLink, you must have an EPROM ECU and that ECU needs to be socketed so you can plug the ECMLink ​flash module into it in place of the factory EPROM chip.  [[socketid|Check ​your ECU]] to see what you have.  If you have an [[https://​www.ecmtuning.com/​images/​photos/​inside1geprom.jpg|EPROM ECU]], great! ​ Then you just need to have it socketed and you'll be set.  You can order socketing service directly off the [[https://​www.ecmtuning.com/​product_info.php?​cPath=25&​products_id=36|Full V3]] or [[https://​www.ecmtuning.com/​product_info.php?​cPath=25&​products_id=44|V3Lite]] product pages (options are listed at the bottom).
  
-For 2Gs ('95-'99)that means a 1995 ECU because that's the only year EPROM ECUs were available for the 2Gs.  ​For 1Gs ('90-'94), EPROM ECUs were available every model year, but you HAVE to check yours to see if you have an EPROM model or not.  ​Additionally,​ for the 1Gs, if your ECU is non-EPROM ​but in good condition otherwise, we do have an [[http://​www.ecmtuning.com/​product/noneprom|EPROM conversion service]] we can perform if you'd like.+**non-EPROM ECU:** If you do not have an EPROM ECUwe can probably convert your non-EPROM ​ECU to EPROM.  ​We can convert all 1990-1994 1G DSM ECUs and we can convert 1995-1997 2G DSM ECUs.  If you have a 1998-1999 ECU, we can __not__ socket those.  ​You will need to locate a 95-97 ECU to use in place of your 98-99 ECU.  You can order the non-EPROM ​conversion option directly off the [[https://​www.ecmtuning.com/​product_info.php?​cPath=25&​products_id=36|Full V3]] or [[https://​www.ecmtuning.com/​product_info.php?​cPath=25&​products_id=44|V3Lite]] product pages (options are listed at the bottom).
  
-We do sometimes have a few EPROM ECUs available here for sale, so feel free to drop us a line if you want.  We provide a significant discount on these ECUs if they'​re being purchased along with a new ECMLink package.  You can get contact information off our [[http://​www.ecmtuning.com/​contact_us.php|contacts page]].+Also, we do sometimes have a few EPROM ECUs available here for sale with new ECMLink package purchases, so feel free to drop us a line if you want.  You can get contact information off our [[https://​www.ecmtuning.com/​contact_us.php|contacts page]].  But, really, unless your ECU is blown or you have a 1998-1999 DSM (which we can not convert to EPROM), then it's a lot cheaper to just convert your existing ECU than it is to buy a replacement.
  
-Another option is to call a few salvage yards. ​ We've found the [[http://​car-part.com|car-part.com]] site to be particularly useful for this.  You may need to call around a few places before you find one willing to check the ECU for you, but you can often run up on a pretty good deal ($125-$200).+Another option ​if you really need a replacement ECU is to call a few salvage yards. ​ We've found the [[http://​car-part.com|car-part.com]] site to be particularly useful for this.  You may need to call around a few places before you find one willing to check the ECU for you, but you can often run up on a pretty good deal ($125-$200).

 To check for an EPROM inside your 2G ECU, pull the ECU out and check the sticker on top. The sticker should have a part number on it (e.g., MD309947) with some other numbers and a letter in the lower right hand corner.

 ====== 1G ECU - EPROM Check ====== ====== 1G ECU - EPROM Check ======
  
-To check for an EPROM inside a 1G ECU, you can start with the same label check described above for the 2G ECU. However, with 1G ECUs having so many problems internally, it's been our experience that the casing for a 1G ECU disagrees with the board inside far more often than is true for the 2G ECUs. The boards inside a 2G ECU tend to stay inside the same case. This is not so true with 1G ECUs, so a further check is required to make sure. 
  
-Open up the case by removing the screws (2 on each "​side"​) holding the top in place. Then remove the top casing half to reveal the circuit board. Compare with the photos below to determine if this ECU has an EPROM or not.+To check for an EPROM inside a 1G ECU, you really need to open the case to make sure. Open up the case by removing the screws (2 on each "​side"​) holding the top in place.

 +**1G NON-EPROM NOTE:** Keep in mind that even if your ECU is a non-EPROM, it can still be used with ECMLink. We offer a non-EPROM to [[https://​www.ecmtuning.com/​product/​noneprom|EPROM conversion service]] off our website. This can be ordered separately or with an ECMLink package. When ordered with the ECMLink package, we can offer this conversion at a reduce priced.
