RC Injector Rampup?

[Jamo]

Hi,

I've recently installed VEMS on 1.1.65 into my S2 Avant ABY, I would like some help getting the injector modelling into the ecu as I don't understand the rampup settings at the moment. It's currently set at 192

RC have supplied some details on my injector latency times for my 750cc injectors.

10v  1.36ms
11   1.12
12   0.92
13   0.76
14   0.63
15   0.50

If anybody could help me please

Well injopen is the open time at 13.2V - so you'd be as well to use 760 for that.
As for the battery dependent factors its all guess work in all honesty

I posted the method I used to determine the injector modeling settings. Whether it was right is any mans guess, as there is not any sensible documentation. Hope you can make use of it. It certainly did not give me any problems.

Can't quite follow is below correct?

RC Injectors

10v  1.36ms
11   1.12
12   0.92
13   0.76
14   0.63
15   0.50

768 / 0.78 = 985

Injector rampup = 985?

I  use both rampup values =0 on all my installs.
Instead I use inj open time @13.2V (about 730 in your case)
and battfact. You can start with about 600 and then experiment with voltage.

My method to determine opening time is just sweep Lambda table values at idle. When opening time is right, ego correction stays same no matter lambda is 0.80 or 1.05.

So like this?

[GintsK]

Yes.

Cheers I will give it a go tonight  ;D
