Edelbrock supercharger is out. Need expert thoughts on it.

[CSG Mike]

I'm not an engineer, but I might be able to answer your questions.

Also, tagging is not working properly for some reason, cuz I totally got to this thread by chance, rather than being tagged...

He did ask for expert thoughts so we need data.

Another thing we commonly did on the Civics. Pre-blower temps are worthless, to you, to the ecu, to everyone. You have to monitor post blower so you can tune IAT comps correctly in the ECU.

Maybe I'll do that at the beginning of the year with tax returns. Hmmm.... If only it was next year already as my unsecured debt will be paid off so I can throw more money at my car!

Can't wait to also hear @johan and @VitViper thoughts on it. If only Counter Space Garage @CSG Mike was in Oregon instead of Cali as I'd let them use my car for testing if they gave me a discount.

If Vitaliy is being honest, he will always say "go turbo" - anything else is a waste of money to him.

That said.... he never did break his supercharged car. Yet his turbocharged cars always seem to be broken before I get a chance to drive them in their "upgraded" states.

Step 1: Confirmed OEM plug on our cars does plug into OEM k20/j3x throttle bodies

Step 2: Started car, throttle body plate does not respond to gas pedal, so maybe wiring issue?

Step 3: Studying wiring diagrams...

Oooo... Nothing fried, I hope. Recommend whenever possible reversing steps 2 and 3. ...if the diagrams are available.

Where's your sense of adventure? :p

Ok - I'm not the most brilliant person at reading wiring diagrams. I can tell from this that it's most definitely wrong... does someone smarter than me want to tell me how to re-pin this correctly?

Right in my wheelhouse. Thanks for the diagrams. Gimme a bit to study but faster, younger, smarter is always welcome.

Let me know if you need more info. I have all of the tech docs for both cars in front of me - just not sure what is relevant.

[Decay107]

For Subaru (assuming they use similar labeling to Toyota)

Well M+ and M- should be your signal wires to the throttle servo
VTA1 and VTA2 are TPS sensor and TPS sensor fault detection (should be a voltage that changes based on throttle position)
That leaves E1 and VC which will be power for the throttle servo and the TPS (constant voltage)

[Ultramaroon]

Are you repinning the TB, or the plug? I will tell you what goes where.

My best guess for a plug repin
Subaru pin => Honda pin

1 => 5 Throttle servo -
2 => 6 Throttle servo +

I might have the next two backward
4 => 3 TPS Sens A
6 => 1 TPS Sens B

Next two are going to be weird
Find the voltage source at Subaru 3 and 5 that matches what is expected at Honda 2 (on the Subaru I think one will be 5V and one will be 12v) and connect it, leave the other disconnected. Wire Honda 4 to separate ground
3or5 => 2
other one N/C
chassis ground => 4

[johan]

Can't repin the TB, it'd be the plug.
