Factory Pro designs and produces the best performing, highest power, probably the most .1 to .2 True HP sensitive and exquisitely accurate EC997 chassis dynamometers around, too. - You can even measure Engine power output smoothness using our industry exclusive "Flux Factor" readings.......  We'll mention that Factory Pro holds the only dyno roller traction improving patents. Think about that the next time you see 10% of your power disappear into smoke on a self proclaimed "state of the art" dealership level dyno!

It's no wonder that Factory Pro accommodates tuners and riders with items and services that will help optimize their engine tuning process success rate and quest for power, performance, efficiency and economy.

"Pro Match" Fuel Injector Sets.

From the simple, "Clean 'em, they are mucked up" to cleaned and batched "2%" to the Premium 1% match to the special order Platinum Match, (theoretically less than .5% identical flow under controlled conditions) - Factory Pro can accommodate the manufacturer, the race team with multiple injector racks and the individual user.

Have injectors that were "ruined" by evaporated race fuel? We can usually revitalize them and put them back in service to "match standards".

We are sure that you'll find a Factory Pro application that will suit your needs.

Performance Plus Fuel Injectors

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.
Watched it done all the time at AMA races..... You'd think that they would know better -

So - what happened? What is going wrong??
Let's assume that the two cylinder with the higher flow rated injectors "were" correctly fueled. The other 2 were 10% and 5% too lean.

So - instead of seeing that problem, as you could with a more sophisticated dyno, like the 4 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:
1 cylinder that is still 5% too lean (power loss), still, 1 cylinder just right (yippee!) and 2 cylinders 5% to 7% too rich (bummer - power loss).

Compare that to all cylinders having the correct amount of fuel......

We did sponsored work for Arclight Racing
They had that problem of unequal fuel metering, cylinder to cylinder - Fix? Almost 2 True HP on 750 Supersport bike - That's diagnosable on the
EC997 chassis dyne system, but not on common dealership level dynos that proclaim "tuning to an "A/F Ratio" as a panacea to lack of tuning knowledge and handicapped equipment -
All for the dealership level dyno's $2000 training per person and $1800 per year to learn how to not tune properly???


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 -
With the 4 gas EC997 dyno..... that indicated..... "This is messed up!"

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 balance injectors.

  Percentage
imbalance
inj. 1 inj. 2 Inj. 3 inj. 4
           
initial 11% 93cc 93cc 100cc 89cc
           
 matched set 2% 99cc 100cc 99cc 98cc

Result?  5+ TRUE HP / peak   and 2-3 TRUE HP / low and midrange rpms.

 



Flash!
November, 2005
All Factory "Pro Match" injectors are now "PULSE CLEANED"
with the new Factory Pro "PPC" solid state electronic Cleaner!!

 Factory Pro "Power Pulse Cleaner" accessory is available for sale to rebuilders-
Powerpulse and Clean up to 16 injectors at a time - This Factory Pro accessory allows you to  rapidly pulse the injectors at high speed while immersed in the cleaning bath of your existing injector cleaner.
Most injector clean and test machines don't have enough capacity to test and clean at the same time. This will allow you to use your tester to test and measure injectors AND also have a set cleaning at the same time - doubling productivity.
Clean AND test at the same time! $750/8 injector model
Save time and improve efficiency and accuracy.

ALSO!
Always interested in trading a "4 injector clean and match" for 4 of your extra, dirty, unmatched injectors.


The Deal -

Call 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.

Call 800 869-0497 and ask about the trade-in deal.
 


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.

 


No injectors on "my" <snicker!> 1944 B-24..... and that's what tuning is... Witchcraft......

That's how they flew B-17's in WW2 - big wheels, big levers and lots of gauges.
