Chris Hasnip Posted June 7, 2015 Report Share Posted June 7, 2015 Hi I have recently installed and wired a G4 ecu into a nissan silvia with a standard SR20 engine. I am having trouble getting it to start for the first time. I used an SR20 base map from PC link and configured all the necessary inputs and outputs to suit. Â When the engine is cranked it appears to have injector pulse but no spark. Â Both triggers have a good signal to the ecu and engine rpm is around 220 while cranking. Â I can get spark from the coils using the ignition test function. Â Any help would be appreciated. Quote Link to comment Share on other sites More sharing options...
Simon Posted June 7, 2015 Report Share Posted June 7, 2015 Hi Chris Do you have an igniter fitted between the ECU and coils? Â Quote Link to comment Share on other sites More sharing options...
Chris Hasnip Posted June 7, 2015 Author Report Share Posted June 7, 2015 Havent fitted an igniter the coils are stock replacements from dsr turbo do these require an igniter? Quote Link to comment Share on other sites More sharing options...
Simon Posted June 9, 2015 Report Share Posted June 9, 2015 Yep most likely. The way to tell will be to measure the resistance between the power supply and the signal wire. If its low 0.5-1.5 ohms then an igniter is required Quote Link to comment Share on other sites More sharing options...
