SDHVW Posted February 19, 2021 Report Share Posted February 19, 2021 Got an EJ25 N/A Gen 3 engine e-throttle on a G4+ Xtreme. In need of some help on the ignition timing or fueling as i cant get the sod to run. Does anyone have a base ignition map for an NA at all?

Adamw Posted February 19, 2021 Report Share Posted February 19, 2021 Have you checked base timing with a timing light? Please attach your map an a log of it cranking. SDHVW 1 Quote Link to comment Share on other sites More sharing options...

Checked base timing I should be near enough there. I have used the V9 Subaru base map to start however that's a quad cam turbo motor with AVCS and the engine i have is NA twin cam with switched cams. So the tables are probably way out.

Adamw Posted February 20, 2021 Report Share Posted February 20, 2021 Your log doesnt show any cranking, it is just 20 seconds of nothing. Battery voltage doesnt change so definitely wasnt cranking when that log was recorded. Can you do another one. Triggerscope looks ok. What size injectors? That master of 13ms would be suitable for something like 800cc injectors. I susgesst changing your pre-crank prime to "key on" since you dont have a start position DI assigned. Also, not really related but I noticed the log shows it is commanding 25% throttle for start up so you should look at that before attempting another start up. It is coming from target + base position + start up step. Quote Link to comment Share on other sites More sharing options...

Cheers for the reply I’ll do another log, I believe the injectors are 280 Subaru part number 16611-AA680, so the master will be way out, do you know what I require for the injectors? yeah I noticed that later on, the idle base position table figures were really high along with the start up step table. cheers Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 21, 2021 Report Share Posted February 21, 2021 280cc injectors on a 600cc cylinder I would expect master will be in the 20-30ms range. Quote Link to comment Share on other sites More sharing options...
