Injector Settings

[AngryRB]

anyone know what the settings for Xspurt 1000cc are? using a power fc with stock regulator, was given info on the deadtimes and at 14v its 0.990, thats all i have.

my old nismo 555's were - 62.5% 0.18ms

what should the new settings be? 37% 0.990ms

???

I did have the data sheet here but I can't find it. Just give Aznew (Injectors online) a call, they are quite helpful. If you have any issues I can ask them today, I have to go and pick up one of the new Walbro 416's they got in stock for me.

Thats where i bought them, i asked about it and they said all they have is the deadtimes list, so that has 0.990 at 14v

deadtime is same as latency is that right? so its 0.990m/s

if thats right then i just need to work out the first part. What are they charging for the walbro, i didnt know they had them, ive seen them for $190.

They are around the same price then.

I have the dead time report here, that is correct for 43.5 psi but it will climb exponentially the higher the fuel pressure and if the voltage is lower. Most tuners will have used ID's and ev14's before so I doubt you will have any issues.

i was hoping to put them in and start it up this weekend thats all, ive sent an email to the tuner, so hopefully he responds by the weekend..

looks like i wont be using the stock reg, just got a turbo smart one, do you still use 43.5psi with 1000cc injectors or do they prefer a bit more pressure?

[scotty nm35]

I was running 40psi base, around 35psi at idle. The stock reg will be fine.

try 37% and +.36

[AngryRB]

try 37% and +.36

is that from experience or a guesstimate?

so do i not use the deadtime for anything?

[JonnoHR31]

Standard injectors are 370cc and .63ms

Your new injectors are 1000cc and .99ms

370/1000x100 = 37%

.99-.63 = .36

There's been some debate about the standard injectors latency so I'm not 100% sure about that but it should be close enough to get it running.

sweet, ill be trying those setting out tomorrow, hopefully it should all fit together without drama's
