Can I run semi-sequential on a 1.6 without changing wiring?
And if so, should I?
Hey guys, just trying to get my idle smoother. Its a 1992 1.6 with a rev build ms3. Right now the idle jumps around a bit and is also pig rich around 11.0 afr. Still getting the closed loop tuned correctly but I keep reading about sequential injection. I know I need some wiring modification to run fully sequential, but what about semi? |
Please explain to me what semi-sequential means.
|
what injectors are you running?
semi-seq. will allow you to run injection timing, but won't really help much in your poor tuning regard. |
18, I can tell you I dont understand it fully. I know the 1.6 runs batch injection stock which fires 2 injectors at once, and as far as I can tell semi-sequential also runs 2 at once, im assuming it just allows you to change the phasing? Dunno. And brain, im running 550cc injectors.

Yep, I get it now. Why not just re-wire, its really not difficult at all, and enjoy proper seq fuel?
I don't see how timing the injection will improve anything when you're still firing off in batch |
I guess I have no reason not to! I figured it was an arduous process. I will look into it.
On my wiring loom that rev provided, he details this: Brown and Green (twisted together) (optional)- Ignition output C (brown) and ignition output D (green) Pink and Violet – Injection output C (pink) (optional) and injection output D (violet) (90-93 only) Does that mean that I run 2 of the injector wires to pink and violet? I disregard the brown and green? If its even on there, gotta pull up the mats and whatnot to check. |
there's no wiring required to run semi-seq. every 90-93 ms3x i've ever built runs semi-seq.
what 550 injectors? rx7 ones? |
Apologies, ive just finished my senior year semester finals and my brain is fried. They are rx7 injectors. I plan on getting some deatschwerks when I get the money but for now im running these. Whats the benefit of running semi over batch, and if I do run semi, what angle should I be squirting? I didnt see anything on the forum about it. Im thinking of just going fully sequential now anyway.
