This is the end result of a few hours of work and $60 because I didn't have a 1/4" NPT tap in any of my kits. I could have done this for less-than $40. The BG products were donated to the cause.
The REASON you want to use 20 PSI is precisely because of how peak-hold type injectors work. The injector signal sends a 4v spike to open a peak-hold type injector quickly, then maintains its open condition with only 1 volt. Really, it's a current thing and there's a longer explanation, but that's it in a nutshell. When you put the injector in its operating pressure, it takes more than a AA battery to open it, but you don't want to sustain that much current with a momentary switch and your expensive injectors. This isn't in the video because this warning wouldn't be as clear. Unless you can simulate the injector pulse precisely, don't try it. 1.5v is enough to open it below its operating pressure. If you open it and THEN apply pressure, you can flow as much pressure as you can throw at it.
I don't discourage anyone from getting their injectors professionally cleaned and balanced, but in my case, I didn't feel that was necessary.
In my first video, I thanked the seller for these injectors and happy to know I got a great deal on high quality parts. My gratitude is even greater because I had problems with them. It gave me an opportunity to help others troubleshoot these kinds of problems when purchasing used parts. A different idiot might have blamed the seller for peddling crap, demanding their money back... but that would only be because they didn't even know what they were looking at.
This particular idiot knows what high quality parts RC injectors are and how to clean 'em. $250 + $60 still means I saved about $150 on a brand new set. We all benefit because I bought these and I'm grateful! Let the good times roll.
DIY Testing & build EFI Fuel Injector cleaner
In this video I detail some quick tests and some not-so-quick fixes.
A dirty or stuck injector is not usually a fatal problem for the part. You
can clean injectors yourself with a little ingenuity, or use an injector
cleaning service. With the method I'm using, you won't get a sheet that
measures how much fluid is flowing, but if you use the right solvent you
can at least remove whatever is blocking it so that it can flow like it did
when it was new.
So the journey begins.
Quick Tip-Throttle Cleaning - EricTheCarGuy
This one goes out to BowlingBallOut who posted a question about a sticky
throttle on his Saturn. It was a great question so I decided to make this
video in response to it. There are many different configurations of
throttle assemblies but for the most part if you have a throttle that is
sticking you might be able to fix it using the procedures in this video. I
am aware you may not able to purchase spray throttle cleaner in some states
now but I'm sure they have some alternative available at your local parts

Learn to test and analyze automotive fuel injector circuits from a wiring
diagram perspective. Fuel injectors are attached to the fuel rail. It is
very time consuming to detect and prove a clogged fuel injector. The
technician needs to disassemble the fuel rail, de-activate the fuel pump
and perform lengthy tests to prove the fault. However, there is another
way. Using current ramping techniques the technician is able to prove the
fuel injector without any disassembly at all. Get the scoop here and save

Homemade Fuel Injector Cleaner - How To
There has been a follow up to this video and it is located here.
This project was inspired by another Youtube member.
I picked up a set of used Blue Max 1650's and wanted to clean them before
I followed the video in the link with minor adjustments. When using
the larger coupler listed in the video, I could not even get the threads to
drill out. I had a smaller coupler laying in the garage that worked for my
injectors. I also used the drill bit one step above the 27/64 listed in the
link. This is 7/16 and just seem to be easier to handle while maintaining a
Another discovery along the way is the size O-rings that you could use
for upper seals. If your injectors have good seals, Why chance ripping
them. A #11 O-ring serves for a great base O-ring on the top side of the
injector. The #78 serves for an outstanding upper O-ring for the upper
seals. You will see this demonstrated in the cleaning video.
One last VERY IMPORTANT note is YOU MUST USE A AA BATTERY FOR THE
SWITCH. I started out using a AAA and had great results on the 950's but
the AAA would not open the 1650's under pressure. After adding a AA
everything worked perfect.
The injectors did measure out to be 2.3 ohms.

How to clean a throttle body and Idle air control valve (iac)
*** PLEASE READ ***
In this video demonstration, I show how to get to, remove, clean, and
replace the throttle body and idle air control motor (aka IAC) on a 4.2l
ford motor. This procedure is the same for any fuel injected vehicle.
* * * Check out my website krkvideos.com * * *
The vans require removal of alot more stuff just to access the throttle
A dirty IAC can cause a rough idle. A dirty throttle body can harm
performance and cause rough engine operation.
When the throttle body or iac is removed a new gasket must be used to
properly seal the connection to the intake.
GM idle air motors are generally mounted on the throttle body and can be
cleaned without removal from the throttle body. This means one less gasket
and a lesser chance of creating a vacuum leak.
The ford throttle body had a note on it that said it was not to be cleaned
because the coating on the throttle blade might be damaged. Thats fine for
a new car but that has to be disregarded when working on something that has
some miles on it.

Homemade Fuel Injector Cleaner Update
Are you having problems getting your injectors to activate on the bench???
Do you want to clean your injectors and NOT run the risk of ruining your
After assembling the Fuel Injector Cleaner in this video
http://www.youtube.com/watch?v=zlO4krw2h8o I noticed these problems and
they had to be addressed. Smaller injectors worked fine with the single AAA
battery, but when I tried the 1650's they would not. This video shows a
solution to that problem and how to get larger injectors to operate on the
Also included in this video is O-ring sizes for upper injector seals. I did
not want to ruin the injector seals that I planed on using in the car, so I
got the O-ring box out and found a set that fit the bill. I share their
measurements and numbers inside the video. This set worked for my Delphi
950cc injectors, FIC Bluemax 1650cc injectors and a set of stock 450cc DSM
Porting an eBay 20g turbocharger
The price of this turbo will make it a
popular purchase, so I figured I'd air out some tech about ways to improve
it. This thing is not for everybody. I wouldn't feel comfortable bolting
it on my car the way it comes out of the box. I could complain about its
flaws except that so far absolutely none of them have been a deal-breaker
for me. To me it's like an empty canvas. I promise to eat those words if
it happens, and share my poop. Usually I can easily correct these flaws
myself and so can you.
If this thing turns out to perform well with what I do to it... It could
easily be a cheap, quick ticket to an 11-second car. Something you could
do with a free running 1g, a hacksaw, and about $500 worth of fuel
upgrades. Yeah, that would be ridiculous, and I'm bolting it onto a
well-modified car... But that being possible speaks volumes for what a DSM
can really do.
This is no big deal to me. I'd rather guinea pig my car for you in HD so
you guys can decide whether or not you'd spend your money on this. Really
it's an experiment because this isn't my daily-driver, and it contributes
to building a better Colt.
Tools I used involve:
Milwaukee model ???? 1/4" straight-shaft electric DIY grinder
Cone and ball-shaped double-cut burs
180 grit high-speed flap wheel
Dremel with a flex-shaft and a tiny 320-grit flap wheel
a zip tie
10mm combination wrench
tiny flat-blade screwdriver (00) for the e-clip on the wastegate
GSX RC 750cc Fuel Injector upgrade
I bought a set of RC PL4-750 injectors. I needed 'em. I had RC 550cc's in
this thing and managed to crank out 357awhp pretty consistently. But I've
restarted my tuning from scratch in preparation for something interesting
I know the tune on the car right now is balled. I started over. No point
in re-tuning for the same hardware. If you want to read more about the
theory behind these preliminary stages, I've included it below. I'll make
a video about it later.
Right now the status is... my MAF is calibrated... I have yet to check for
Boost leaks... and as for how the
injectors turned out?.... You'll have to watch what's next.
All of my tuning adjustments have been made to the airflow tables by
calibrating the BoostEstimate value
in DSMlink against actual logged Boost from an AEM 3.5bar MAP sensor. A stock
MAF sensor has a temperature sensor in it. A GM MAF sensor does not.
Using a GM MAF clamps the intake temperature at 80° no matter what they
really are, this makes air mass calculations a little more difficult.
Without the intake air temperature sensor, the GM part is never calibrated
correctly for use on a DSM. GM cars have a separate IAT sensor so they
don't have this kind of issue. Their ECU will correct for the sensor's
behavior based on air temperature. My configure relies alternatively on an
air pressure value.
By calibrating airflow tables (maf correction) to bring BoostEst (an ECU estimated value) and actual
logged Boost pressures dead-on...
The air mass is being accurately metered, and as a result, it brings all
the STFT and LTFT fuel trims to within 1% or less. That's the short
explanation. It was tuned after achieving zero Boost leaks and a steady idle.
I will be doing this again with the 750cc injectors after a healthy round
of Boost leak testing, but some
other things need to change first.
Common rail injection system
The injection technology used in the TGL and TGM is the most sophisticated
one: a state-of-the-art common rail injection system with vertically
positioned 7-jet injector nozzle. The latest generation of EDC7 control
units provide the controls of the system. Only this system ensures the
best-possible control of the fuel injection process. In each compression
stroke, the injection quantity can be divided into pre-injection (1) and
main injection (2). In some cases, a post-injection (3) is used. The
engines operate with an increased maximum injection pressure of more than
1,800 bar in order to reduce the soot particles inside the engine. The
engine runs extremely quietly and noise emissions are low due to the
pre-injection (1). The common rail system also supplies considerable
advantages in torque, particularly at low speeds. At all engine ratings,
the favourable progression of torque across a wide range of engine speeds
makes driving economical and requires very few gear shifts.
