Bespoke Calibrated Lambda Sensors

Rice Racing - Fact V Fiction

We have used many different types of lambda sensors, some well known others not so. Commonly some lesser types (Non NTK) are proven the world over to be a second or third rate choice with respect to durability suffering from in tolerance to certain fuel types and operational limitations, rendering them useless for anything but the novice or hobby type user only.

Now getting one to work is solved the next issues revolve around accuracy across ranges seen in various racing internal combustion engines. For the 'common' consumer grade NTK sensors they will come with a very average gross overall calibration resistor which is only a very rough trimming device used to span 'normal' operating ranges. Some lesser ECU systems rely on this which is 'easy' but far from a proper solution. They can vary + - 5% in a good one to give you some idea, this is totally unacceptable in a highly stressed application.

Real quality suppliers (I mean real ones who make their own racing engines on behalf of major Automotive manufacturers) and others who supply to the highest levels of racing series around the globe, will only offer individually hand calibrated Lambda sensors, shipped out with a unique file which will then insure the said sensor is accurate and repeatable across the full span of mixtures used for internal combustion engines.

ECM - ETAS - MoWreC - insert other AIDS 'claimed to be the best' - all are run by RICE RACING, the only person to ever test and own these 'in house' & now offering 'high end' services to anyone who reaches around to me. Also offering real 'unobtainium' NTK racing oxygen sensors for those who want to flex and run the highest quality real racing items. !!!BEWARE OF CLAIMZ!!!, we do this (run oxygen sensors and various 'instruments') every day! and get sent items and buy them personally! to check them, no bias, no ca$h for comments! :)

VIDEO & PICZ BELOW SHOWING WHO IS THE HARDEST KUNT - THE TESTING DONMEGA !

This ECM AFM1000D was sent to RICE RACING for validation, I checked its performance against my two ECM 4800P units as well as checking its variation when running another brand new ECM supplied NTK calibrated sensor!!!

NOTE!!!! these units DO NOT USE I.C.C. correction the differences shown as simple from running the supplied sensor and a brand new sensor

This knowledge was applied and used by a major after market ECU manufacturer and tested in real world on track where it matters in the most shit engine man has ever created - 13B TURBO ROTARY !!!

If you or your TUNA cant work out the H:C and O:C or the "DA BRO" Christopher Skase OXY KONTENT on the day of your test, or know the effektz of I.C.C. applikation and where and where not to use it then his a dumb kunt !

NAZI KUNTZ! HITLER YOUTH! "narrow bandz dont work" - righto kunt!

EVERY SINGLE MOTHER FUCKING SENSOR VARIES!!! DUZ NOT MATTER WHICH SCIENTOLOGY BRAND OF AIDZ YOU CHOSE TO RUN OR PREACH TO SUM KUNT! YOU NEED TO ACCOUNT FOR IT NOT WITH THE FAKTORY CAL CHIP BUT AKTUALLY MAP THE KUNTZ OUT! ONLY THE DONMEGA DUZ THIS!

EVEN ONCE KALIBRATED (does not matter who duz this - Horiba, ECM, DONMEGA) THIS MUST BE ASSIGNED TO YOUR SELF WORSHIPED BRAND OF AIDZ INSTRUMENT!!! IF YOU DONT DO THIS THEN THE KUNTZ WILL READ THESE LEVELZ OF ERRORZ BELOW!!!

REAL MOTORSPORT NTK SENSORS! OPTIMIZED BY THE DON!

Run up as delivered using factory NTK cal resistor and std air calibration method, IE: as run by 99.9% of users NOT VERY PROFESSIONAL

BUT IT IS CAN BRO !

BUILT BY RACERS FOR RACERS - PICK A NUMBER ANY NUMBER !

NO AIDZ !

This is what Rice Racing offers, having supplied to many end users running Life Racing, Syvecs, Magnetti Marrelli, Pectel/Cosworth ECU's to name but a few quality brands.

Types worked on:

(NTK Only !) LZA09*, L1H1, L2H2, And we can check/calibrate your motorsport and laboratory grade NTK (various part numbers)

The process of analysis and calibration

Analysis of 'as delivered' accuracy, here is an out of the box new NTK consumer grade Lambda sensor. Very large errors across the normal ranges and horrendous errors at extreme ranges.

Before calibration basics of the % of Oxygen in the AIR is evaluated by taking local measurments of the temperature/relative humidity/barometric pressure and our reference meter is set to this. Every sensor is monitored for gas temperature and hex body temperature and tested with both known reference gas and under combustion loads in a specially made gas chamber which gives uniform stable distribution. Each one is checked 4 times over multiple days to ensure a tight tolerance and repeatability to ensure the best possible calibration curve being achieved. The end results in static and dynamic gas mixture flow tests is generally a + - 0.25% range deviation. Achieving a Laboratory grade reading result for a fraction of the cost.

RICE RACING also offers kustom Autronic BDS9 spec meterz, these are done by the factory to my specification and also each one is calibrated here to precision and can run any 4mA or 6mA NTK sensor as well as the old LSM11 !

These units are further modified and fine tuned to work with RICE RACING banded specific sensors attaining a level of precision and accuracy that is unmatched by anyone anywhere

RICE RACING has a proven list of tuned sensors approved and tested for hundreds of hours, we can modify and upgrade, reach around for POA
