Charles,

You should be able to purchase directly from the website. Just add the item you wish to purchase to your shopping cart. We accept most major credit cards, if you do not have a paypal account. Or you can pay with an e-check, or western union, or a money order. If you decide to pay with Western Union or a Money order, make them payable to Joel Parrish, at the address listed at the bottom of the website. We will ship your item Global Priority(4-6 days according to the USPS website), so you will not have to add any additional charges for shipping. Feel free to contact us with further questions or concerns.

There are no additional charges for international orders. There is not an
additional $5 charge, unless you wish to donate..

Our simulator should work fine on your vehicle. Sorry it took me so long to
get back to you, it's been very busy. Feel free to contact us with further
questions or concerns.

i heard the service center fella told me everything of hyundai need ori,if go for mod type the ecu will create problem stuff like engine warning light on. Maybe they are bullshiting who know.

 

[limch1]

Yeah, it's gonna be 50-50 thingy, else nothing much can be done too..

 

[limch1]

Just bought the O2 simulator from the website. Hopefully it'll will fix the CEL problem. Still waiting for the unit to arrive.

 

[limch1]

OBD (OBD-II) Scantools

With the use of the right software, these OBD scantools are far more useful than just reading the CEL error code. It is a complete advance diagnostic tool that will look at most or even all of the functions of the car. It is a very handy tuning tool or just something cool to show your friends. Here are some of the readings that you can derive from it:

Read diagnostic trouble codes, both generic and manufacturer-specific, and display their meaning (over 3000 generic code definitions in the database).
Clear trouble codes and turn off the MIL ("Check Engine" light)
Display current sensor data, including:
Engine RPM
Calculated Load Value
Coolant Temperature
Fuel System Status
Vehicle Speed
Short Term Fuel Trim
Long Term Fuel Trim
Intake Manifold Pressure
Timing Advance
Intake Air Temperature
Air Flow Rate
Absolute Throttle Position
Oxygen sensor voltages/associated short term fuel trims
Fuel System status
Fuel Pressure
Freeze Frame data
Continuous and Non-Continuous Oxygen Sensor test results
Data graphing and logging

[limch1]

Interesting webiste, thanks for the info. Wondering anyone try it out before?

 

[limch1]

But the little red pill, is too expensive...

 

[limch1]

I found out that after putting the device, the 2nd O2 sensor is unable to get any exhaust reading, hence throwing another CEL with different code.

I've just shorten the add-on and hope this time the 2nd O2 sensor will pick up some reading, not too much exhaust gas and not too little, just nice will do.

Then I'll fool the 2nd O2 sensor that I have CAT installed. Still on the trial.

 

[limch1]

My car got throw in new CEL code.

P0422 Main Catalyst Efficiency Below Threshold (Bank 1)
P0139 O2 Sensor Circuit Slow Response (Bank 1 Sensor 2)
P0140 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 2)

Finally I'm back to normal. I've fixed back my original extractor and no more CEL for me. The car suddenly sounded so quiet as compare to last time. I believe the best is not to change any aftermarket extractor for Elantra.
