Ah, the third sentence I quoted is ambiguous. Sorry for the confusion.

I read that a few months ago and came to the conclusion with some digging that Fuel Injector Connection is garbage and Fuel Injector Clinic are not. While not AS nice as ID they may be more than enough for most. Keep in mind I have no idea what the specs mean for any of these companies. Only research into who seems to have good quality stuff.

No need need to be Sorry I am glad I can clarify.
Both ID Injectors and Fuel injector Clinic injectors are great.

I just wanted to point out that FUEL INJECTOR CONNECTION is different from FUEL INJECTOR CLINIC.

I try my absolute best to sell products that I would use on my car.
Fuel injector connection IS NOT a product that I sell.

Holy crap DOAP. You just explained the huge ID vs. FIC fight I see all over the web.

Fuel Injector Clinic is great, it's connection that are teh shady SOBs it appears after some research that answers a lot of wtfs I was having on this topic.

Good to know. I see at least one reference (Ben91) to Jon Banner at Fuel Injector Connection (i.e. the shady guys) so it's worth differentiating between them to avoid confusion.

Anyone have low-DC matching data for their FIClinic injectors?

Who does this kind of testing and what does it cost? Link to trusted service provider?

Savington

AFAIK only ID does it, which is why I want to see if anyone's found data from FIClinic.

Low-DC matching is critical because EV14s are all over the place out of the box. This data is for ID2000s, but the point is the same.

100 injectors, every 10th one tested:



Think a car will idle right with that much difference between cylinders at low DC?

Here's a set of 6 that have been dynamically matched (high and low DC):



That's why dynamic matching matters.

Injector Dynamics - Does Dynamic Matching Matter?

There are no drop in ev14s afaik, all of them have to use adapters of some sort, even the modified ones. A 700 cc size is produced by bosch under part number 0-280-158-040. http://www.bosch-motorsport.de/en-US...2775993867.pdf
(There are larger sizes also but for CNG and snowmobile applications which are probably used as the base injectors for high flow modified injectors.)
If you only need injectors in the 550cc range there are several options that while not being drop in can be made to fit, ford GT500 M-9593-LU47 injectors being an example. Ford Racing 47 lb/hr EV6 Fuel Injectors - Set of 8 - Home for your Ford Mustang

That says EV14 in the description, but it seems like an EV6 price like the title says.

It must be a typo as the body is ev14. FORD RACING 47 LB/HR FUEL INJECTOR SET - Livernois Motorsports
Interestingly 8 of these injectors make 624 hp?

That's an impressive chart. It certainly pays to buy in bulk and do your own testing. At such low pulsewidths, that's going to be A LOT of variation in volume with a 2000cc injector. I understand why you preach ID, and how you manage to get a better than stock idle with and injector that flows 10x more than stock.

Like you say, they don't fit. Anyone make one of those aluminum hats to fit these Ford injectors into our fuel rails? Even if someone did, if we believe ID (and I'm not saying we have any reason not to) they aren't really that well matched from the factory anyway, at least for low duty cycle as the ID graph that Andrew posted indicates.

It sounds like the strength in the Injector Dynamics product lies in the level of consistency and testing across the entire range, rather than just matching the injectors for total flow.

I'd be very interested to see if any other company out there does similar dynamic testing.

Ahh you may be correct that they get used. From the information I've gathered, some of the ID1000s start as the GT500 injectors and get the flow limiter removed, the FICs start from a different injector. And basically everyone's 2000s are the CNG ones (which theoretically need the seals replaced to be e85 compatible). I do rate the multiple sources I found that info fairly low quality.

sturovo

I guess the ID/FIC injectors are usually not based on the long body ev14s as they use adapters to correct the length. If you wanted to adapt 60mm ev14s (type used by Ford) to fit the miata fuel rail it is relatively straight forward as the overall length is compatible.



The plastic diameter at the injector neck needs to be reduced to 10mm and a couple of o rings need to be swapped but they fit ok.

sturovo

I am skeptical of marketing material.
The first chart indicates an error mean of -0.02 and standard deviation of 4.63 at 2ms pulse width using data points (5, 4.5, 4, 2.5, 1, -2.5, -2.7, -3, -9)
Been a while since I looked at statistics but assuming normal distribution, is the second charts < 1% error level probable?

So here is my summary of Sav's chart with high/low DC.

I stand in the yard and water my flowers with a garden hose. Water (fuel) is turned on all the way (fuel pump 60psi or whatever. Just a constant). Low DC is me trying to get an exact amount of water out by kinking the hose, letting go, and re-kinking it. Try one is .2l, try 2 is .4l, try 3 is .2l, the point is it's a hose and hard to eyeball a perfect amount. High DC is just letting the sucker pour out the open end. All the hoses (injectors) I can get from the store (ID) can flow the same as long as I buy the same size hose (ID1000s). The difference in low DC is their testing of the retard kinking the hose again and again? IE how accurate and repeatable I (the kid playing in the yard) can be. I may be more accurate and repeatable with the hose (ID1000's) than my neighbor with the same size hose (ID1000s) All the same type of hose from the store and bought from the same place. Just some variance in hose kinking or amount of fuel at idle.

sturovo - I'm starting to drink your koolaid.

From what I'm reading, a set of unmodified unmatched ev14 injectors will be as well or better balanced than matched modified ev14 injectors. Keeping the atomization plate should be a plus too.

Can you speak more to your GT500 injector experiences and modifications? Specific hardware, what works/didn't work? It looks like one could easily save a couple hundred depending on their flow needs.

Spec sheet:
http://www.fordracingparts.com/parts...-9593-lu47.pdf

Looks like there are options for up to about 900cc

Edit:
Why are ID's deadtime so much better? Ford's slope min/max deviation is significantly better, even accounting for max flow rate.

The other graphs on ID's site seem to be modified vs modified injectors. Granted, this is a sample of one set, but it's interesting data from a third party on ID's site.

sturovo

meowmeows, I have not yet fitted GT500 specific injectors but have modified other long body (60 mm) ev14 ford injectors to fit the mx5.

[IMG][/IMG]

Any of the long body ev14's should fit in the same way as the dimensions are identical. (I ended up using only one o ring at the fuel rail connection as it was way tight with 2.)
