I need to know the sensor type for the FIC. And I'll be using a rubber hose for starters (it's part of the kit anyways).

Thanks cdydjded for confirming that too. I actually thought it was hall effect.

Now, here's the thing. I've been getting very familiar with the FIC install guide and have been debating what I want to do with it. I remember when I first began looking into forced induction, there was at least one mention in every thread about how much of a pain our ECU is due to its learning ability. Originally, I had planned to get the FIC to control as much as possible, but the more I think about it, I think it's the wrong approach. I'm aware that, in the least, I need to use the FIC to provide additional fuel during boost conditions. I admit my knowledge on ECUs is lacking, so I'm hoping you guys here (and my potential tuner) can shed some light on the following: will the ECU make an attempt to adjust timing / ignition / cam position etc. etc. when it sees boost conditions + additional fuel? Or will it rather trim fuel and try to maintain ideal conditions?

cdydjded, this is aimed mainly at you. I know you already told me you were only running fuel maps. However, I was reading one of your older threads recently and saw your plan for how the engine should run: stock without boost, FIC handles boost conditions. I couldn't agree more when it comes to reliability and overall effectiveness. Was this ever achieved?

Ultimately, my epiphany was that I could possibly use the ECU's learning capability to actually aid in having a proper tune, rather than it just being an enormous hassle. Lemme know what you guys think, I'm hoping to get it wired in this week.

Thanks, I'll be taking the same route then.

Today I was poking around in the engine bay, scouting out places to place senders for gauges (and also installing a 1zz TB ). Figured out what I'll be doing with everything but the oil pressure gauge. I really can't get at the engine oil pressure assembly. Literally 10 minutes ago, this idea hit me: http://www.glowshiftdirect.com/oilfi...-34unf-16.aspx

Couldn't I use this as a place to receive oil pressure readings AND use as an oil return line for the turbo? It would be installed such that gravity would still return oil properly. My only concern is the filter would be having additional oil dumped in at all times. I'm pretty sure it's not an issue, but could clogging potentially happen?

[Bluevitz-rs]

The oil filter it pressurized. You can only return oil to the pan. Once you have the oil pan off, it's really easy to just drill and tap the block for one. But you could feed the turbo from that plate.

Planning to install it tomorrow actually. I'm going to hook up injector ins/outs as well as power and ground of course.

Today I went to go wire the FIC up, but got kinda confused... This ECM pinout I'm using has got me all sort of confuzzled. Check it out here:
http://www.powerenterpriseusa.net/pr...risControl.pdf

Firstly, everything has two different wires listed and I have no idea what the acronyms stand for. So basically, I have no clue which wires I should be using to tap/intercept. It looks like some things are listed as + and -, while others aren't. Here's what I think needs to be done...

FIC Power - A21-1 or A21-2
FIC Gnd - C20-104
Injector 1 - C20-108
Injector 2 - C20-107
Injector 3 - C20-106
Injector 4 - C20-105
MAF+ - C20-118
MAF- - C20-116

The thing is, even for the injectors, C20-45 is listed next to all of them and I don't understand why? Enlighten me pleeeease. In the mean time, I need a beer.

... and aloe.

[Yoda]

can't help you but i am rooting for ya m8

[Focus_Sh1ft]

Thanks a bunch man.

[Bluevitz-rs]

That C20-45 is probably your common sensor ground. It's separate to the ECU ground.

Not to put you down on wiring (because I love doing wiring. No joke.) but I'm glad my ECU is under the dash and not the hood.

cdyjdjeded can probably help you he's got his wired correctly. Try a PM request

Each injector has a common wire which is the POWER wire that goes directly to IGNITION +12V or else to the ecu 12V power (same condition). This is probably the C20-45. If you have a multimeter, do a continuity check from the injector common wire (this should have the same color on all injectors) to the positive terminal of the battery while ignition is on to confirm this.

The other injector wire is ground connected to individual ecu output ( in your case C20-105 to C20-108. The ecu activates the specific injector at a point in time by grounding these wires to make a complete circuit.

Regarding the MAF I cannot help you since I always work with MAP sensors which work with vacuum.

Fortunately for you I am almost doing a fresh engine management install so I am pretty sure I know this is the right route. So ask and I try to help you as much as I can.


IF you have an echo or yaris 2001 - 2005 the connectors on that manual do not match since I tried it myself. I didn't found a manual for mine so I had to cut all sensor wiring and connected them directly to the new ecu myself.

Thanks for the input guys. I definitely would like to hear from cdydjded on this.

I'll be doing a continuity check to confirm C20-45's function. However, it's clear that C20-105 to C20-108 are the wires that need to be intercepted for the injectors. At this point, I feel pretty confident I had the right wires so I think I'm gonna give it another shot. The only part that is unclear is which power source wire needs to be tapped. I doubt it matters though because both the conditions and specified conditions are the exact same.

When I hooked up the E-Manage blue I tapped into the 4 injectors and the common sensor ground wire. The power for the injectors should be coming from the EFI relay and fuse.

[Focus_Sh1ft]

Got the FIC wired up today. I wired up the obvious power and grounds, along with injectors, tps sensor, and maf. Everything worked fine until I wired in the maf wires... The engine just kind of chugs and doesn't start. Interestingly, when I put the jumper harness in to bypass the FIC,it starts but I have a CEL. However, I think it has something to do with the TB as this literally just happened on friday when i disconnected the positive terminal of the battery for a prolonged time. It went away a few hours later.

Anyways, I'll be getting my 2.25" catback exhaust with a flowmaster super 44 tomorrow. I need to pick up some steel lines and adapters for oil return and feed. Also will be calling the tuner to talk a little more and setup an appointment.

Otherwise, I plan to begin the install wednesday and hope to have it done within 3 days time. Again, expect LOTS of pictures. I want to share the (hopefully) fun of the install with you fellow YWers

[Bluevitz-rs]

You're sure you didn't hook the MAF up to the FIC backwards right? I know on the e-blue there was in from MAF and out to ECU.

[Focus_Sh1ft]

Wow come to think of it... That definitely is it. I didn't think about it when I was wiring it up. Instead, I wired it exactly like the injectors... in from ECU, out to engine. I'll switch them tomorrow.

cdydjded, The only reason I hooked up the MAF wires/tps sensor was to potentially aid in tuning. I also thought it would allow me to avoid a CEL with the turbo in and running. However, the more I think about the setup of the Zage kit, I'm not sure if I'd even have a CEL. The MAF sensor goes before the turbo, and I'm keeping my stock o2 sensors. But wouldn't that throw out system too lean/rich codes?

[Focus_Sh1ft]

Was just combing through the Zage kit and noticed their turbocharger has 4 inlet/outlets (6 actually, 2 are welded). Could this possibly mean it can be water cooled? I don't know how to tell... I'll snap some pics of it tomorrow.

[Focus_Sh1ft]

Reversed MAF wires and now the engine runs
Still have a CEL though... Gonna get the code read later.

[Yoda]

can't wait to see you mount it up
