AFPR too? Sometimes they're needed because the 255 will overrun the stock FPR

I only asked because I've seen issues with the spacers that cause the throttle plate to not close all the way. I can see on your video that the TPS is fine where it is. My point is that if you wind up adjusting the throttle plate, you'll need to do the TPS afterwards.

I think that's a problem, pretty sure they're incompatible with the USDM wiring. Swap your stocker in. If you need the fat bung, just take it out of a stock USDM exhaust manifold.

Yeah, well you need to verify that the outputs are configured correctly for the gauge.

Put your hand over the discharge port! Seriously, try it.

Do it. Now.

Chris ,

I will look into everything esp the O2 sensor, I had to extend the wiring so I just matched it to stock plug but its the JDM O2 from an OBDII Car my car is a 92 maybe thats 1 problem that I was unaware of. Ill add my OEM 92 SE-R one tonight.

I have a fat bung already in the J-Pipe ( AVENIR W10 ) so my US one should go right in.



O2 to stock wiring

FYI - You can also use the narrowband output output of the LC1 to replace the stock one.

Gauge im almost 190% is wired correctly.. First week of driving the car was spot on and was driving fine. Just had an idle issue. Other than that pulled hard 12-12.5 AFR no smoking no backfiring no sooty exhaust just ran awesome but idled crappy.

Stay tuned...
