Now that my engine is broken in and running well, I am starting to run LOP and have one injector (#4) that is a bit rich compared to the other 5. It does not peak until the other cylinders are 10 to 30 degrees LOP. My engine is a stock IO-540 C4B5 that was overhauled locally in Minnesota. I am interested in finding someone who will be willing to work with me to get the injectors matched closely. I had GAMI injectors on my old Bonanza and they were great. But, I don't want to spend the money for GAMI's on the Lycoming. This is standard Bendix fuel injection system. Any thoughts or ideas will be appreciated.

You could try swapping the injector with whatever cylinder is first to peak.

A few years back there was talk of an experimental version of fuel
injector that changed an insert in the injector rather than the whole
injector like Gami. I googled to try and find them, but came up empty.
You might switch the #$ injector with the one that peaks first to see if
it will help even things out.

You can try these guys. You can replace individual nozzles. I am in the
process of doing it this annual cycle......no results yet. I collected the
data, put it in excel and sent it to them and they provided me restrictor
recommendations.........

Let you know how it works.

Hi David,

As Kelly said, you could swap injectors on your own engine
to see if you can get the high and low's closer together.
That's one option. Otherwise, you could buy a couple
of other injectors swap them around too. Aerosport has a
flow system to check and balance them. You may be able
to send your injectors to a place like that and see if they
can match them up for you.

Also, with the EFIS you have, you'll want to buy a copy of
EGView, by EGTrends. It's got a GAMI leaning module in it
so you can download your data on some nice slow leaning
runs, and it will actually tell you how far off your injectors
are, and what kind of flow increase/decrease you want.

David,I too have a used IO540-C4B5. I pulled the entire injection system off and sent it to "Airflow Performance" for overhaul. All 6 injectors were replaced with their injectors. They can balance the fuel flow by replacing an insert in the injector once you are flying. I have not yet done this, but plan too. We are just finishing up our Phase I.You might give them a call. Great to work with and they know the engine well.Jim C40192 - Phase I - Flying.--> RV10-List message posted by: "dmaib(at)mac.com" <dmaib(at)mac.com>Now that my engine is broken in and running well, I am starting to run LOPand have one injector (#4) that is a bit rich compared to the other 5.

At what min/max should one make a change to tighten the spread? At what min/max should one be satisfied that it is good enough without wringing out the last 2% that costs triple?

David,

Here's the do-it-yourself procedure...

Very worthwhile, I run 50-75 degrees LOP all the time and enjoy very
economical operation.

In my case it is not an effort to wring out more performance, just need them close enough so that the engine will run smooth and I won’t damage any cylinders. Of course, running LOP is to get better gas milage……running 50 rich a peak at ~12,000 to 14,000 I was burning 12.0 to 12.2 at speeds in the lower 160’s.

Thanks Randy, Jim, and all the rest who have responded. Sounds like a
good excuse for a trip to Spartanburg for one of Airflow's private
nozzle tuning sessions is going to be in our future!

Any excuse for a cross country at this point. ^_^

Will they help you with both Bendix and Airflow Performance
injection systems to balance the nozzles? If so, that's
mighty cool of them. Good road trip.

GAMI normally aims to get the cylinders within 0.5 gph between first and
last to peak, with 0.3 gph or less being very good.

If you are high enough that your engine can't produce above 65% power,
you can run at peak or perhaps 10 LOP all day long and not hurt
anything. I'd guess that at 12K you are already at or below 65%

I think I might have disremembered those numbers. I think the real guide
is at 0.5gph or greater between 1st and last to peak, GAMI or Airflow
can improve your performance, and probably get you to 0.3 or better, 0.2
or better is very good.

Yes,Based on their recommendation, I had them overhaul my Bendix Servo (And complied with an AD), replace all the injectors with new Airflow Performance units, replace the flow divider with theirs and got all new fuel lines from the flow divider to the injectors. I have the excel spread sheet and instructions on how to fill it in to get the "balance" data. Cost to tweak the injectors is very small ($20 if I remember right). They will do it at their airport or ship you the parts after they have reviewed the spreadsheet data.I have a very nice running engine at this point and have been very happy with their service and advice.Jim CombsN312F - Phase I (34 hours)--> RV10-List message posted by: Tim Olson <Tim(at)myrv10.com>Will they help you with both Bendix and Airflow Performanceinjection systems to balance the nozzles?

They help with both. Twice a year they host a seminar for 4 to 8 lucky soles. The dates are March 6, 7 and 8 for 2009 and again in November. I have signed for two slots in November after completing a Conditional on an RV which had an adulterated Flow Divider. Diaphram was overtorqued and the secret safety wire had been replaced. Rapid turn around, excellent service and a great excuse to take my wife to see the Smithsonian and a drive down to the Carolina coast. Colleen even suggest her favorite spa while I play so my wife does not get restless.

Colleen and Don are a pleasure to deal with. They encourage you to bring your fuel injected aircraft to use in training. Tuning the injectors is a big plus regardless of wading into the clear value of LOP operations.

old A&P need state of the art training too!

Will they help you with both Bendix and Airflow Performance
injection systems to balance the nozzles? If so, that's
mighty cool of them. Good road trip.

Thanks Randy, Jim, and all the rest who have responded. Sounds like a
good excuse for a trip to Spartanburg for one of Airflow's private
nozzle tuning sessions is going to be in our future!

Any excuse for a cross country at this point. ^_^

David,

Here's the do-it-yourself procedure...

Very worthwhile, I run 50-75 degrees LOP all the time and enjoy very
economical operation.

I spoke with Don at Airflow Performance, and he will help with Bendix
or Airflow. He is sending me a data collection sheet. I will take
initial readings and then when I go to Spartanburg, we will adjust
the nozzles and fly the airplane. Don says it typically takes two or
three 20 minute flights to get them balanced.
