Cleaned - Tested - Matched One of the last (did I really say "last"?) mysteries in poor power production is commonly experienced in fuel injected engines. Poor power - caused by mismatched injector fuel delivery. What prevents many semi-professional tuners from diagnosing the the problem of poor power production caused by variances in fuel injector fuel delivery rates, is the use of O2 sensors on dynamometers, and "tuning to an A/F Ratio" schemes, as promoted by "sellers" and "marketers" of dynamometer equipment. When a tuner uses a dealership level dynamometer to tune, he will commonly look at an air fuel ratio that is based on the amount of O2 (oxygen) that is left in the exhaust. They will then change the injector pulse width to richen up all the cylinders so that the amount of O2 left in the exhaust gas is some "magic" so-called "A/F Ratio - commonly... 13.1:1 according to latest urban legend proclamations by common dealership level dyno manufacturers. Let's assume that one injector flows 10% less and another 5% less than to other 2 injectors, who luckily are within 2% of each other. They "A/F Ratio" crowd will richen up
the fuel injection, and proclaim that it is as good as it can be and
they don't know why the bike isn't one of the better examples of that
model bike and send it out the door or out onto the track - not crisp,
not smooth at part throttle / high rpm. So - what happened? What is going wrong?? So - instead of seeing that problem, as you could with a more sophisticated dyno, like the 5 Gas EGA EC997 chassis dyne systems, the tuner will simply richen up all cylinders until he gets some "magic" A/F Ratio (based on that exhaust residual oxygen %) and call it a day - So - what he actually ended up with was
sort of like this: Compare that to all cylinders having the correct amount of fuel...... We did sponsored work for Arclight
Racing We had a GSXR750 that had been to multiple shops for poor power as a complaint, dynoed on "dealership level" dynos - using "a/f ratio" scheme for diagnosis. This example is one of the worst
occurrences that I've seen except for injectors from engines that
have been running AMA legal race fuels - One them had a mysterious
3-4 TRUE HP loss -
After 1 test, the 4Gas EGA EC997 indicated that "average" fueling was OK, but, the O2 level was very high - as was HC (hydrocarbon ppm). CO2% was sub 8%. Can't diagnose that on a dyno with an O2 sensor and the "A/F Ratio" scheme....... Another reason to NOT tune to an "A/F Ratio"........ Diagnosis, after 1 test, - Step 1 - Pull the injector rack, clean and match the injectors.
Result? 5+ TRUE HP / peak and 2-3 TRUE HP / low and midrange rpms.

ALSO!
Perhaps interested in trading a "4 injector clean and match" for 4 of your
extra, dirty, unmatched injectors.
The Deal (if we need them)-
Call 416 491 5920 first to see if we need more of the injectors that you have -
Send in 8 dirty, fuel additive contaminated units and we will clean and match all and send you back one 2% matched set of 4 injectors at no charge, except for freight. We will keep the extra 4 injectors for our stock.
TECH
100% flow rate values (flow rate through the metering orifices) should not be used for matching purposes - You need to factor in "Pulsed" flow rates -
Pulsed flow rates take solenoid "action" + flow rate through the metering orifices into account and give data that is more relevant to the real world operation.
Fun
No injectors on "my" <snicker!> 1944 B-24..... and that's what tuning is... Witchcraft......

| The extension of the laboratory
for engines of the Swiss Federal Institute of Technology was completed
in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940).
He had a successful career in Berlin but returned to Switzerland after
the advent of the Nazis. His architectural style was somewhat similar
to that of Erich Mendelsohn. The staircase of the laboratory is in normal
use but well preserved. Edited to the tunes of Chemical Residue by Herbie Hancock. |
