Hows it going everyone, just got a few newbie questions about tuning a S300. I'm planning on getting a eTune from http://vittuned.com/, I have a wideband in my car but I haven't wired it to my ECU yet (is that necessary? I believe, I am suppose to wire it up to D10 or D14?) Also, I have a cat on, I still have a o2 sensor still hooked up, and 1 is deleted (just a screw that is the same size as the sensor) then after the cat I have my wideband o2 sensor, just wondering if that would make a difference when datalogging/tuning my car when time comes.

Here is my setup

1996 Integra GS-R
USDM ITR Pistons
Crower Stage 2 cams
Stock Injectors
Stock Map Sensors
Skunk2 Pro Intake Manifold
Skunk2 66mm Throttle Body
Blackworks TPS Sensor
Skunk2 Fuel Rail
Password:JDM Intake
Tsudo Headers
Yonaka Catback Exhaust 4.25"

Could anyone give me an idea what numbers i'll be pushing out, if possible?
Thanks!

 

You will need to have the wideband connected in order for someone to look the datalogs and see the readings. The wideband should be before the cat to get an accurate reading.

Details on wiring in an O2 sensor for the s300 can be found at http://www.hondata.com/techplxwiring.html

You may want to talk to your tuner about how they want everything hooked up prior to tuning.

 

i didn't have any more space to weld the wideband before the cat, would it be alright to just put it into the cat seeing that i have the delete?

 

Yeah if there is no cat then you can put it wherever you want, but ideal placement is within 2 feet of the head. Those Crower cams don't overlap much but they have a high lift, be extra weary about piston contact.
Make sure the TPS is properly installed and calibrated before you do anything else, most people screw that up.

 

yeah, i made sure i did it right when i got the blackworks TPS sensor. hooked up and made sure it read 0% on the s300.

 

Okay, so I got my wideband welded in front of my cat, now I’m going to be wiring it up to D14, I was wondering if I have to do anything else like calibrate my gauge and sensor together before I start data logging to send out to get tuned? Or what else needs to be done?

 

a tune is where the tuner connects his own wideband and his own laptop directly to your car while physically sitting in your car.
all this stuff you're worring about is pointless. talk to your tuner, they will instruct you what to do.
if they say they can "tune" you car by having you email them something, find a new tuner immediately.

 

not trying to step on any toes here, but im trying to do an eTune from a well known tuner, I understand the the basics of physical tune and having someone in the car to get it tuned, but not that many street tuners or dyno tuners around my area.

 

I noticed a different in my gauge reading when I connected my wideband to ECU D14, nothing I should be worried about right?, i know i have to change the offset value, but do i have to before i start datalogging? im trying to send out it to my tuner ASAP.
