Hi... first post here.

I have been reading a good bit, and I feel like I have a pretty good understanding of how to turbo a 420A "properly".... but I need advice.

I just got a used eclipse 2gnt with a hahn 16g kit on it. I just finished replacing the head gasket, water pump, timing set, etc, and it runs now with the help of some starter fluid to get it going.

It is equipped with yellow injectors, which I've read are most likely 510cc. It has an Apexi AFC Neo hooked up, which I've read is useful in tricking the ECU into pulling some fuel with larger injectors. It also has a variable rising rate regulator to increase the fuel pressure.


I have a wideband installed already, so that is good to go, and a fuel pressure gauge. I have some 4.7v / 4.3v zener diodes on the way to make my own Fuel cut defender, since the one that was on the car before must have been removed or something... MAP wires were twisted and taped :-/ !??!? Also, running forged pistons, so that is good news.

So.. my questions are.. where to begin? I know most people here will say "get a hahn port fueler", or "run megasquirt".... megasquirt is in the plans for sure, but in the meantime I need to get this thing running under minimal boost with what I have so I can justify the additional cost of megasquirt.

So, I plan to pull the vac/boost ref off of the rising rate regulator and set the onset. Right now it comes on way too early, I believe while still under vacuum.

How would you tune this thing in? Where should I be setting the AFC Neo?

Thanks.
