KA24de Plug identification and t25 setup questions

Post by Johnny_k »

Sup guys been on the forum for awhile but never signed up. Now that i got the turbo on the engine and engine in the car i have a few questions and hoping you can help.

Any help would be appreciated. I have a drift event in 4 wks, it still needs a break in and tune.

First up, I need help identifying these plugs.

Plug 1 - im pretty sure this is an 02 sensor and not needed, can someone confirm?

1. O2
2. Knock sensor possibly
3. ? Maybe A/C
4. Evap solenoid
5. Evap solenoid
6. Looks like TPS
That is typically run to a catch can then valve cover or just to the valve cover. You can block it off.

If you took the Evap stuff off, you won't need 4 and 5. You can use those solenoids to make your own staged boost control, however.
1 is only important if you are going to use your stock O2 for any reason. Most wideband systems can simulate it, and a stand alone ECU will not need it.
2 you will need if you want to use your knock sensor on a stand alone, or if you are using the stock ecu.

You know, somebody actually complimented me on my driving today. They left a little note on the windshield, it said 'Parking Fine.'

2 looks like it could be for the speed sensor as well. Not sure where it usually stays, though. I have my A/C removed and I never saw a spare one of those-type plugs.

1 definitely O2 sensor

6 positively TPS

3,4,5 - probably emissions garbage that I never needed :D those are unused on my harness too.

u are correct, the only one i have plugged up is the TPS and the car starts and runs. thxs for ur help.

So as far a vacuum lines, do we only have the 4 under the throttle body, FPR, and brake booster?

Trying to figure out where to put vacumm lines for the wastegate, bov and boost controller. Heard the FPR vacuum is a big no no

I have just 4 vacuum lines. Brake booster, BOV, boost gauge and turbo to waste gate.
Boost gauge is on the vacuum running from the nipple on the back of the intake to the fpr. Works just fine
BOV is hooked up to a vacuum under the throttle body. Works just fine.
Ones boost controller will T into the line in between the turbo and waste gate, and then the other vacuum source for the boost controller goes to the top-hat on the waste gate.
