rudypoochris Posted July 5, 2007 Share Posted July 5, 2007 www.megaefi.com Apparently there is an adapter to connect a Megasquirt ECU up to the stock 87-95 Mustang EFI harness. Has anyone had experience with these or a similar product? If so, do they omit any functions, are there any draw backs to them versus using your own harness? Thanks!

Matt Cramer Posted July 5, 2007 Share Posted July 5, 2007 I've installed it on two cars so far. It does omit a few of the stock ECU's functions, mostly emissions related (although if you really wanted, I suspect you could put those back). The only time you're likely to run into problems is if you are using one of the later Ford automatics - that's something of a can of worms.

rudypoochris Posted July 5, 2007 Author Share Posted July 5, 2007 Thats great to hear that it only really omits the automatics and emissions. Since I am using a manual and am emissions exempt (although I do hope to try and save the air as much as possible). As far as configuration and installation goes, is it the same process as using a standard megasquirt (as if the adapter wasn't noticeable) or are there other hassels that come along with it?

Matt Cramer Posted July 6, 2007 Share Posted July 6, 2007 There are a few things you sometimes need to set up differently in the Megasquirt, and it has a few circuits located on the EEC-IV adapter board that come in handy for relay controls and such. But it's mostly invisible when it comes to setting up the Megasquirt. I have a write-up on them here: http://www.diyautotune.com/tech_articles/megasquirting_your_ford_with_the_MegaEFI_EEC-IV_adapter.htm Quote Link to comment Share on other sites More sharing options...
rudypoochris Posted July 6, 2007 Author Share Posted July 6, 2007 Wow, thank you very much! I have work in a few minutes, so I haven't had a chance to read your article, but i did notice on the megaefi website that they listed the unit as being able to run fans. Does this include the two speed Taurus fan? Quote Link to comment Share on other sites More sharing options...
Matt Cramer Posted July 6, 2007 Share Posted July 6, 2007 Yes. The EEC-IV adapter board has four generic relay output circuits (each with a blinking LED) that can be used to control a fan relay. You can set up the Megasquirt with one output for low speed and one for high speed. Quote Link to comment Share on other sites More sharing options...
