Taiki Posted June 22, 2023 Report Share Posted June 22, 2023 I am trying to control a JDM Honda Civic 1987DOHCZC with atom, but I keep getting trigger errors! I've changed thresholds and rewired but no improvement. Can anyone give me some advice? Quote Link to comment Share on other sites More sharing options...
essb00 Posted June 22, 2023 Report Share Posted June 22, 2023 Your Trig2 is wired with incorrect polarity. You need to interchange the wires. I cannot confirm if Trig1 is wired correctly there on the scope, but you better check the wiring as well. Can you also attach your map/tune file plus the actual triggerscope log file?

Adamw Posted June 22, 2023 Report Share Posted June 22, 2023 Im not very familiar with the ZC engine, but the obd0/1/2 distributor wiring info below may help if they share any similar parts. The factory Honda ecu used a rising edge trigger signal whereas the Link ecu needs a falling signal, so the positive/negative wires need to be reversed with Link compared to the factory ecu.

Taiki Posted June 22, 2023 Author Report Share Posted June 22, 2023 Thank you. I didn't know that they had to be connected in reverse to make a falling edge. I have wired trigger 1 and 2 directly to the Atom. I have attached the trigger scope log and map file. The base map is using 92-95 civic link TriggerScopeLog.llgx Honda Civic 92-95 G4X Xtreme Plugin modifded_2023_6_22.pclx Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 22, 2023 Report Share Posted June 22, 2023 It is hard to tell in that scope capture as the engine is cranking slow (maybe flat battery). Can you remove the sparkplugs so it cranks over faster and do a new triggerscope. Quote Link to comment Share on other sites More sharing options...
Taiki Posted June 23, 2023 Author Report Share Posted June 23, 2023 Thank you all. I switched the wiring for triggers 1 and 2 and it started. Trigger error is almost non-existent. PCデータログ - 2023-06-23 5;47;27 pm.llgx Quote Link to comment Share on other sites More sharing options...
