Can I run semi sequential?

Post by tima »

hello! I am wondering how (if possible) can I set up my S60 to run my VR6 semi sequential injection. I have the cam sensor wired but I am not sure how I would setup the table? Can anyone help.

Heres a video of the car on the rollers :)

I think if you switch on 'Two Stroke' mode this will fire the injectors every revolution as opposed to every other as normal sequential - or do you mean something completely different?

Surely if you have a cam sensor fitted, you would want to run fully sequential ?

Otherwise, why bother ?

I am assuming because an S60 doesn't have 6 injector drivers, stevieturbo.

correct, s60 only has 4 igniton/injector drivers, so I am running two cylinders per driver

That's a very good reason ! lol

Not a lot of benefit using a cam sensor then.

Next question...what does one define "semi-sequential" as ?

cylinders paired on the opposite stroke
1342 4pot = 1+4, 2+3
165432 6pot = 1+4, 6+3, 5+2 (my one anyway!)

etc, imo.

yep, so if same as above wire
  • Inj1 -> 1+4
  • Inj2 -> 6+3
  • Inj3 -> 5+2
Main Eng settings/ Inj in 2-stroke Mode: Yes

Go into Sequential Injection settings and put in the Injector Offsets:
  • Inj1 = 0 (should be this by default)
  • Inj2 = 240
  • Inj3 = 480

Of course, adjust to suit your firing order.

Have fun :)
