Thanks for the offer frontrange (nice screen name BTW)

I'm under the assumption the EGR is a sealed unit, right? The diaphragm shouldn't let air past or am I mistaken here? After replacing the intake I sprayed starting fluid to see if I had any leaks and if I spray anywhere near the EGR valve the rpm's increase considerably.

Sounds like you got a cracked EGR diaphram. It should be sealed but after enough miles they fall apart. That's your first problem, it sounds like yours is in pieces.

Yes, sure does. Thanks for confirming that for me. It may be the key to the emissions failures. I'll check it out again and take it from there. Of course you've got me wondering about the injectors but first things first.

Yeah I would still check the injectors just because I bought three different sets from three different sources and all of them were a mess when I bench tested them. I've never seen anything like that with Bosch or Rochester any other type of injector for that matter.

Now I suspect any Toyota injector (and I'm not a big fan of the rest of their FI system either as you may have noticed). My 2FE is a complete redo of the fuel delivery and a aftermarket ECU with a crank triggered ignition. I kept the Toyota injectors, but only because I had plenty and milling the hardware to use a Bosch was too much of a pain.

I would like to follow-up after I deal with the emissions if that's good with you. Thanks again for your help.

Sure, no sweat. Good luck with the EGR.

Do you have a build thread anywhere?
I have a 3FE but am interested in aftermarket ECU that fires injectors sequentailly vs. the gang firing the stock ECU does...

Hijack over!

No, no thread. I have to get this project done soon, so far all I have finished is the custom tank and fuel delivery, the custom rail setup and the Ford EDIS-6 conversion and the ECM completed and tested. I used a megasquirt controller. The engine still needs assembly, I only just got the 3D toolpath done and tested to eyebrow the cylinder walls to relieve the valves. Next I'm making a custom Hydraulic cam. Should be starting that soon.

You do know sequential fire will have zero impact on performance, right? All ECM's operate in bank fire mode once you are in the engine's powerband. Sequential operation is basically just a means to lean out the AFR during idle so you're not dumping unburned hydocarbons in to the atmosphere when stuck in traffic.

No, I did not know this.

Thank you.

I would still be interested in reading a build about your 3FE when you are finished.

Where are you located?
