Fuel Injector Testing & Cleaning Machines

I doubt the ultrasonics are worth much. Cheap ultrasonics result in for performance.

The machine is probably too cheap to do a good job

 

One of my good friends is RC engineering
They make all their own equipment, very high end to do the job right.

The stuff the sell like those are just to "upsell" a cleaning
Lots of folks buy them and say I am a fuel injection specialist.

I have seen the equipment side by side in operation, like a VW bettle vs a porsche
Better off with a pressure pod to clean the entire top end

 

Yeah you nailed it, just looked at LOL Chinga

 

Fuel injector cleaning is one of the biggest hypes in auto service today.

From Cars.com "Cleaning fuel injectors is a service frequently recommended by dealers and repair shops, but unless there are noticeable signs of clogged injectors (such as a rough idle, stalling, poor acceleration or high emissions levels) it might not be necessary. One tipoff is that fuel injector cleaning is not typically listed on automakers' routine maintenance schedules."

From: "5 Car Maintenance Procedures You Don't Need: Scam Watch"

"2: Fuel-injection cleaning ($125-$200)

"This is a fair price for this service, which uses another impressive machine -- but only if your fuel injectors are actually dirty, and you have driveability issues because of it. If your Check Engine light isn't on, and your car's running fine, pass."

And please don't start in on "but it's a Ferrari so it's different". BS. It's generally a hype and waste of time/money.

 

If you don't have any of those problems, why assume there is something wrong with the injectors? And if you do have a problem, as you say, there are a host of things that can cause drivability problems and most of them aren't dirty injectors. If the car been sitting, neglected, for years that's really another issue, no? There is a difference between correcting a problem and doing something which is more than likely unnecessary because some shop wants to jack up you service bill. At least, that's my take on it.

 

Just my interpretation of "quite a long time"...."seen the effects of "old" or crap fuel."

If you want to buy an injector cleaner it's your prerogative. Different issue. I've got any number of tools I just had to have and have never used too. We all like our toys.

I just don't believe there is any point in making injector cleaning part of routine maintenance. Just use quality fuel and change the fuel filter periodically.

 

I have a machine like this, from 'Launch'.
And it did show me that 2 of my injectors were less than ideal.

On the injectors from a 2nd engine, it showed me that 1 injector was giving too much with a odd spray pattern and a further 2 were poor.

After using my own heated ultrasonic tank, the 2 lazy injectors cleaned up. But the 1 giving too much is now in the box labelled "buggered".

So it certainly was cheap and from China, but it served a purpose.

 

I'm in complete agreement.

If it ain't broke, don't fix it.

A while back one of my clients insisted that his injectors get the treatment during a major. They were returned with a wonderful report indicating that they were now at tip-top performance. Can you guess the next part? One injector was now dead. I wasted a bunch of time trying to locate why the car now only ran on seven cylinders.

 

You know I was half hearted joking when I said it's another "after sell" item they sock it to you with

But in all fairness. YOu should know what your injectors are doing

True they dont clog like they used to due to the additives in fuel today whitch is insanely better then 5 years ago.

The deal with a tester sure it tests but what can YOU do to fix modify the injector? Pro's I mean real pros and I can count them on 1 hand make a stock looking injector do magic until you get caught by Race Tech

They have parts custom made and they wont let anyone know how why when where but Boy Howdy they work

 

I disagree with Tim and John. For me personally "consumer acceptable" is just not enough. As part of my majors I have been having fuel injectors serviced and I walnut shell the intake valves and ports. Labor is free for me as a diy guy so I can afford to send my injectors out to a high quality guy like RC engineering. I'm lucky because I can get my injectors back in a few hours if I drop them off in the morning. Will your car run ok if you don't do the service? Probably. But in my opinion dirty spray patterns effect performance. Why just replace parts like timing belts without trying to optimize performance? To me that means I cam time the motor, clean the injectors, and clean the intake. IMO these things are low hanging fruit. If I'm not going to do these things I may as well just use assembly marks to set up the cams. 90% of people putt-putt these cars around and can't tell if they are running on 4 cylinders let alone feel proper cam timing. So for those people good luck to you.

What got me routinely servicing fuel injectors was random misfires over several different cars over time. Since I started routinely cleaning injectors I can't remember the last time I had an injector related misfire. Our fuel supply is dirty. The fuel is poor. Ethanol blends and nasty stuff for winter california blends, water etc. OEM's put screens in the injectors and fuel filters in the cars. It's because the fuel isn't clean. Cars that sit get even more deposits. We know that optimal performance comes with "as engineered" spray patterns that are easily disrupted by many things. In search of more economy and horsepower 4 orifice injectors have smaller individual ports to foul vs. the big single hole sprayer of old generation injectors.

Any people having marginal smog numbers really need to look into optimizing the OEM parameters. I read about so many people not being able to pass smog and I just shake my head...
