Grahamp4 Posted November 24, 2018 Report Share Posted November 24, 2018 Hi, New to ECU's, Have just rewired my car which has a CA18det and using Link G4. Everything seems fine until I try to set the timing. At TDC for the exhaust stroke with an offset of 260 deg the spark plug will fire but when I set the offset to -100 deg for TDC of the compression stroke I get no spark. Have just changed the CAS as I thought that was the issue however still not resolved. Any help or hints would be appreciated. Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 24, 2018 Report Share Posted November 24, 2018 Is this a plug-in ECU? Have you tried the ignition test to make sure all coils are connected/sparking? Do you have stable RPM showing in the software when cranking? Quote Link to comment Share on other sites More sharing options...
Grahamp4 Posted December 3, 2018 Author Report Share Posted December 3, 2018 ECU is a Storm G4. Ignition test is fine. Injectors test is fine. In fact set everything up with no problems and went to start it and it wouldn’t start. Realised i’d Set the timing on the exhaust stroke and then tried to set on compression stroke and now I can’t get the timing to work. Getting stable rom at about 300. Ok real weird one this. Have just managed to set the timing by attaching to a plug whilst on top of the engine. Eg plug in cylinder no spark. Plug out get spark. Plug in the cylinder will fire at other times when there is no compression. This is a project that I’ve picked up 50% complete so have limited history Quote Link to comment Share on other sites More sharing options...
Simon Posted December 3, 2018 Report Share Posted December 3, 2018 What coils are you using? And if they are not smart coils do you have an external igniter fitted? Stock CA coils will need an igniter external. Quote Link to comment Share on other sites More sharing options...
Grahamp4 Posted December 3, 2018 Author Report Share Posted December 3, 2018 I am using a high performance 4 coil pack from NZEFI Quote Link to comment Share on other sites More sharing options...

Grahamp4 Posted January 9, 2019 Author Report Share Posted January 9, 2019 Still having issues with getting the engine started. With a plug out of the cylinder I can see a good spark when I do an ignition test, however when I turn the engine over the spark is significantly weaker!

Simon Posted January 9, 2019 Report Share Posted January 9, 2019 What's the voltage supply to the coils like are you seeing an excessive volt drop to the coils under crank so spark is reduced? Is fueling in the ball park, Not excessively lean or rich? Quote Link to comment Share on other sites More sharing options...
