Just got my AutoProm!

[Xenon]

Just came this morning... Where to start? Guess I have to get the g2 soldered in first ...

Does anybody have suggestions on how to start? Is there a bin that would be close for my 406sbc or should I just start datalogging and go from there?

Excited to finally be doing this

Re-read EagleMark's introduction to tuning... Good info.

What's your opinion... Would I be better off trying to work from a 454 bin to start or the 350 one that's in it?

Running 7747 ECM now with adyr bin... Obviously lean. Just start by datalogging it and see what I have/don't have?

Thanks guys. Were it not for this site I would probably still be carbureted! Lots of great info here.

First thing to do is get esimated HP of engine, figure what injectors at what pressure is correct, adjust pressure and then calculate BPW.

From this post works well with TBI.

Then you can move on to tuning.

What are cam specs @.050 ?

As far as I know it is the stock cam, so 203e 196i with 112 separation.

Not sure though, as I did not build it. It could have a mild performance cam in it...

The injectors are currently the stock 350 injectors. I know I have a lot of work to do and a lot to learn yet so bear with me...

I googled images for bear with me and this is what I got...

4.1555 bore x 3.75 stroke = 406.87 cubic inches. 61lb/hr injectors at 85% duty cylce .05 BSFC to support 257 HP needs 20 PSI fuel pressure will flow 75.66 lb/hr and BPW of 132.

That's only a guess on HP so no WOT high RPM runs without a wide band O2 sensor to see if it has enough fuel!

Apply the BPW hack in $42-1227747-Vx.xdf so you can watch injector duty cycle.

Well I'm gonna have to show how little I know and ask what exactly that means...

I could have said "bare" with me instead. That'd probably make for a fun image search
