New Injectors....

[Headsex]

Here's the 80lb Siemens spec sheet from Ford Racing USA

Scalars, breakpoint, and Min Pulsewidth

Battery offset table

GT42R on the standard bottom end for now.. and push the power up more..

your nuts!

I hope you have a dust pan and broom in the boot so you dont leave your bottom end on the road

Just build it Danny & stop playing games

Ok. a update on these 80lb injectors..

I do NOT recommend these injectors unless you NEED to make big power. The minimum pulse width of this injector is 1.58 milliseconds. Far too great for idle, unless you set your idle to 1100rpm.. In gear when the engines loaded up a bit, its happy at 800rpm at lambda 1. But when its in neutral/park, forget it, Rich idle.

Also when installing these injectors it pays to have a good "light boy" hehe

Thanks for the quik feedback on these injectors, as usuall your a wealth of information.Slightly off topic,did you get that dyno sorted and up and running?

The 80 lb figures have been rereleased and are different to your original figures, may be give them a try after modifiyng them for our fuel pressure

These injectors are now Happily running in my car at lambda 1 at FACTORY IDLE rpm.. that's right, approx 600rpm in gear. or 750rpm in netural. See below for more details.

As Mick has pointed out, Ford Racing have Re-released the injector values.

I Emailed them regarding the problem I had, where the pcm was idling on the Minimum pulsewidth causing a excessively rich problem as the minimum pulsewidth was too much fuel.

I told them I experimented with Lowering the Minimum pulse width, but cranking up the Battery offset table because the PCM shuts down the injectors if the calculated fuel pulsewidth is LESS THAN the "minimum pulsewidth" remembering that if the injector doesnt have enough pre-open time, It may fail to open anyways, So the injector needs at least 2ms opening time I've been told. But the problem is, the PCM's equation does not include the Battery Offset ms opening time in the calculation for minimum pulse width.

They told me they were already well aware of the problem and were in the process of re-releasing the spec sheet with the new finalized results. Obviously Mick saw them before I did.

So if you compare the original and revised specs, you will see that, the min pulse width was set to 1.57ms, and now a revised 0.599ms. BUT in the Battery offset table, the pre-open time at 12volts was originally 0.595ms, and now a revised 1.25ms.

So, If you look at this following v2 Specs from ford Racing

Here is the calculated details @ 4bar base (58psi)

great success

[Headsex]

that's right!! So next time your around here, we need to alter your injector values to suit :D
