Nothing worse than opening a can of worms... Oh wait yes there is... I bought a can.

Sorry More questions.

Who knows about the AEM 30-4100. I bought on thinking it was just going to display my AFR. After glancing at the DESTRUCTIONS, it seems this thing also controls something. Man what did I get myself into?
Has any one ever install one of these things?... Or do i need to go to M.I.T. just to figure this thing out. :eek:

Yep! I'm going to be a problem child! :rolleyes:

I think it is just a guage. I'm pretty sure that is what I have in my truck.

Looks like a nice gauge to me. I like the 2 1/16" size. I should probably pull my boost gauge and just run one of those.

I bought a fuel pressure gage and it came with npt threads on the pressure switch. There is no place on the fuel line I can mount the switch.. Is the a piece I can buy to put in line with a stock fuel line set up?

The Shrader valve on the passenger side of the fuel rail is 1/16 NPT. That's a really odd size and you probably won't find anything with that thread pitch at the hardware store.

However, Autometer makes an adapter for it. I picked mine up at the Racing Zone in Arlington when I did mine over 2 years ago. Anybody that sells Autometer stuff should have that adapter.

Thanks I did not see that on my lines... Ok off to the garage again.

I did some more looking

Fuel Rail Adapter; 1/16'' NPT Male to 1/8'' NPT Female Adapter for fuel rail
105-3280

Autometer partnumber 3280. You just remove the shrader valve on the fuel rail and replace it with this adapter and the sensor.

Well at least we agree, but you knew the size, I did not.:tu:

OK I got everything hooked up but the fuel pressure. I cranked it up, all the lights worked the afr zipped across the scale and back, then settled down at 15.5. I let it warm up till the idle down, and give it a little gas, and let off. The gage pegged as I was pressing the peddle and then when i let off it bounced back to 13.1 then settled back to 15.5 Is this right? I thought 12.5 was the # to be at.


Thanks for the part #'s. I'll get it tomorrow.


Thanks

The wideband should read 14.7 at an idle. Sometimes it takes a minute or two if the engine is cold, but once it goes into closed loop mode it should read correct.

14.7 at idle and cruising, 11.5 to 12.5 at WOT.

I got to drive it to Dallas today. And I watched the afr most of the way.
Slow in-town driving afr readings bounced between 14.9 and 15.5
HWY driving 65 + mph 14.4 to 15.5
1/2 throttle take off 13.5 (about)
3/4 take off 11.1 to 12.5 (6 pounds of boost)
I did not take off WOT. I try-ed, but cops every where this morning.

Thanks for the link Mark#2 I ordered it this morning.
