So it started with some brand new OEM injectors. I tried everything with the "600cc" from PEC and it ain't started. I might give the "DSM 450cc" a try as they seem pretty common in S12 CA18ET tuning community... Or I will switch to a new fuel rail with standard injectors. Thanks ...

Ticking just means that the solenoid is opening the pin. So all four are spraying with your testing which is good. The idea of lowering K constant is to reduce injection time for the larger injector, based on actual size vs previous size It is a bit of a concern that more current is required for th...

EDIT : merged this post with previous one.

So it starts with some brake cleaner. Injectors really seems to be guilty... However, they "tick" when using a stethoscope. I unmounted Injectors and they aren't clogged. Spray pattern is decent and a very similar between all fours. Unfortunately no one wants to flow test them as they are ...

Thanks a lot for your answer. I will try this in the morning (as it is 3:42am here, I think my neighbors won't appreciate my tuning experiences :lol: ) The only thing that did not get tested in my setup are those injectors. As they were brand new, I trusted them blindly.. and a problem is that my OE...

A little video to show what's happening. Brand new plugs gapped to 0.8mm. Timing is still spot on. https://youtu.be/wBHLK7PCFu8 Injectors are these ones https://www.ebay.fr/itm/153814226101?mkevt=1&mkpid=0&emsid=e12052.m43.l1123&mkcid=7&ch=osgood&euid=e9ea2d22bf2549cd81dd645cc7f2...

Still not starting
It catched pretty quickly but stalls immediately.

Hi Matt, I'll give it a try thanks. This difference might be caused by the fact that my ECU is a 33F01 and I am using a 33F01 main image instead of the 33F00 that you used for your screenshot ? Did not knew that such a small change in K constant could cause a non-starting engine condition :( EDIT : ...

Hi, I fitted a nistune type 1 board on my nissan s12 ECU (33F01). It worked nicely with stock injectors. (All the engine is stock) After upgrading stock injectors (270cc) to 600cc ones, I can't start engine anymore. Spark plugs keep getting carbon fouled. In this post I will briefly tell what I unde...
