jeff berkers Posted September 17, 2013 Report Share Posted September 17, 2013 Hi, I have an old g1 ecu that's been lying around for ages and i'm trying to work out what engine it's configured for? There are no numbers on the outer case so I've pulled the case off and not much more luck! The main circuit board has a square chip thingy with a sticker on it ''d42v3'' which i'm guessing says it's an older version 3? and also ''090499'' which is possibly the date of manufacture? it has the date 1998 printed on the circuit board. It has a smaller circuit board screwed on top of the main one which has the 4 dip switches in a blue lug which are set at 1-on, 2-off 3-on 4-off. also has a smaller rectangular chip with ''cd40106be h9701'' on it. I was told many moons ago that it was possibly for a SR20 but cannot verify this. So my questions are; What trigger input is it set up for? And what do the dip switches do? Can it be changed to run dizzy, wasted spark or cop? provided the correct trigger inputs are used? Many thanks for any info you may have.

Simon Posted September 18, 2013 Report Share Posted September 18, 2013 Its a G1 version 3 It is for distributor applications only The sub-board is an opto / hall board so will work with any optical or hall sensor where the is a tooth per TDC.

Simon Posted November 6, 2013 Report Share Posted November 6, 2013 A mazda GTX/R 1800 distributor would be a good example. Quote Link to comment Share on other sites More sharing options...
