Ecumaster forum

Hi!
I have an 200SX S14 with the SR20DET engine. I have wired up ECU Master, but i cant get it to start. Car was running fine before with Apexi PFC.

Stock SR20 with 550cc injectors.

I have checked every injector using the output test. I do also have spark on every coil. Note that Cyl 1 is wired to ign. output 6.

I have verified timing with the lamp, and its correct. I was at first struggling alot, and the timing was totaly off.
I enabled the advanced filter function and set output offset to 2. And then timing was perfect. I have also checked that the cas is in the correct posision.

But still it wont start. I have tried increasing / decreasing fuel on both prime pulse and cranking fuel. I have some bangs out the exhaust when trying to start. But its nowhere near starting at all.

I am running out of ideas and i was hoping you could help me out.

Map and log file is attached.

you are using a very strange arrangement of ignition output connections and sequence, i would plug the wires into IG1=coil 1, IG2=coil 2, IG3=coil 3 & IG4=coil 4, and check your firing sequence 1342 or 4213

Bangs or backfires mean your firing sequence is wrong or your timing is 360 degrees out.
