Most of the set-up will be done on the street, but I'll eventually get to the dyno just to see what if any HP gains I've made.

Where have you wired your tacho lead to ?

I forgot to ask, are you planning to run sequential of phased injection?

[MrPerkles]

actually I was going to ask you that as well,semi sequential (fires two at a atime) the ecu guy who sent the start up map says it reduces the load on each driver and uses it where possible.

Injector 1 FUEL1 B4 brown black 1st firing (Cyl1)
Injector 2 FUEL2 C3 brown yellow 2rd firing (Cyl6)
Injector 3 FUEL3 C6 brown red 3rd firing (Cyl2)
Injector 4 FUEL4 C2 brown orange 4th firing (Cyl4)
Injector 5 FUEL5 B5 brown green 5th firing (Cyl3)
Injector 6 FUEL6 B3 brown violet 6th firing (Cyl5)

What about you ?

[Trog]

I'm running full sequential, hence the cam-sensor.

[Trog]

I'm pleased to report that I've reached substantial completion. All the wiring is done, the fuel lines are complete (Pro-Lite 350), and the vacuum lines are pulled.

All I need to do is load in a start-up bin-file and balance the ITB's. That will have to wait till next weekend. With hope, it will start-up without any grief.

Now THAT is an absolute work of art engine bay. Job well done.

Congratulations on your progress.
A couple of points.

a) How did you go with finding suitable spanner for the inner nut no #4 (manifold to head)?

b) Instead of the fuel lines doing a loop around both sides, split the supply line with a "T" and then another "T" on the return prior to the regulator. Three reasons to support the two parallel paths.
1) The original Porsche installation was done in this manner,
2) I know of some WRX guys (WRX having a similar left and right side cylinders) who initially used the one loop and found that the cylinder(s) at the end of the supply were running lean, causing engine damage. By splitting the supply line and feeding both sides evenly, and with a similar lengths of line between the fuel rails to the return"T", then to regulator , etc. the problem was solved.
3) A mechanic with our V8 super cars has advised that they used the two parallel paths (one per bank) for there fuel lines.

Maybe there are some others that could make comment.

wow neat job Trog well done
couldnt get mine going yesterday ecu kept showing ofline so lots of head scratching to be done today

Paul,

a: I used a regular nut. Because of the taper on the throttle body manifold, the only way to thread the nut is to elevate the manifold and start threading the nut. As you advance the nut, slowly lower the manifold until it mates with the head. Then it’s a simple manner of tightening the nut with an open ended spanner.
b: Noted. If I detect a lean condition, I'll reconfigure the fuel lines as suggested. However at this time, I plan to proceed with "Clewetts" recommendations (ie: looped fuel distribution) as a base-line.

What type of serial cable are you using?

[MrPerkles]

I dont think its the cable ,i cant get a switched live to the ecu even though I have wired it as this diagram

[Trog]

It’s important that your switched 12-VDC is “On” both during cranking and running. Otherwise, the engine will not fire-up.

[Tooth911]

dude!!!

[Trog]

IT'S ALIVE!!!!!!

Like a kid at Christmas, I couldn't wait to play with my new toy. So I double checked everything, loaded the Bin-file provided by "Clewett" and turned the key.

Half an engine rev, and she sprung to life.

I'm pleased.

Now it's time to learn a thing or two about tuning.

Stay tuned.

Trog..

Great thread and beautifully detailed install...

Quick question, you're using the Tech-lll R with coil packs, In the pic I see you're original coil still in place.. just sitting there disconnected or???

Hi Paul,

Thanks for the kind words.

I'm using the TECgt.

The original coil is abandoned. I've since removed it from the engine bay.

Trog..

Yes, what I thought & was just curious. I have a similar project which will use TWM 46mm throttle boddies.

I'm still gathering parts and info and will find your thread most helpful I'm sure. Have not been following the world of ECUs lately so wondering what made you choose TECgt over
TEC-lll? Was/is TEC-lll discontinued or is the gt just that much better?

Thanks again,

Paul

[Trog]

I purchased the ITB set-up as a kit from "Clewett Engineering". Personally, I don’t have enough knowledge of what’s out-there to make an educated decision. So in times like this, I defer to the experience of others.

So far, no regrets.

Rgs,

Paul, I just installed the TecGt in the turbo and am very pleased. Very tunable and user friendly, and I believe cheaper than the 3r. IIRC, clewett said the 3r was better for twin plug application. Electro seems well past the issues that gave them a bad rap in past.

Troy, congrats!

[ChkbookMechanic]

Very nice! Glad to see it running. Let us know how the throttle response is compared to the standard intake.
