All Injector Dynamics injectors are high impedence, so no need for resistors or driver boxes.

These and most aftermarket fuel injectors are all top-feed requiring new fuel rails for both primary and secondary, unless you plan on keeping your stock primary injectors (or modding for use of stock secondaries, not recommended).

Many people have been using 550/1600 without too much issue, and these 2000's are much more linear, enough down low to idle a rotary! (my boss is doing some testing on his n/a GTUS and running only 2x ID2000's in the primaries...) There will not be a big stumble/hesitation when the secondaries come online.

 

well being this has been brought up with these yaw injectors can i run a total of 6 injectors directly off the PFC with these injectors? such as 2x 1000cc pri and 4x 1000cc secondaries without the addition of an extra driver box?

sorry no pics from me but im very interested in running these after hearing about them from one of AZRR's builds

I was not positive that the PFC could control such large primaries, but Glen mentioned that they were able to run a fairly lean idle at only 1.5ms with the 1000's. Definitely able to run 4x 1000cc secondaries on the PFC.

 

So where do you get the donuts to mount these injectors?

 

Sorry, missed that question... The denso donuts like those pictured in the photo I posted should be available from the Injector Dynamics dealer you purchased the injectors from. If the dealer does not have any, contact T1 Race Development.

 

the 1000cc primary was just for example purposes i have every intention of dropping in some rx8 470 primaries to have my buttery smooth idle control and the 4x 1000cc in the gz mani.

but im looking for a little more hard numbers as to what i need to do to run the 4x secondaries off the pfc just a Y-lead of the stock harness or a different impedence injector to double it up? the whole thing with these wanting to be used was they were a rather large cc high impedence injector making them damn near PnP for the PFC but doubling the injector being driven by one driver was the reason low imp inj use resistors.... so running the 4 high imp makes the same issue arise no? or running them parallel/series through the driver going to make them not burn up the driver? im just looking for a hard reasoning why they will "work"...

anybody have the IMPEDENCE of these 1000cc inj so i can run some numnbers or already running what i want to do with numbers to back it up?

One that is on this board belongs to Rccaz1. We built this car with 4 id1k injectors and two rx8 primaries. The car made great power 440 at about 16psi. This car has a pfc and it runs these four just fine. Paul Yaw took the data from the nec drivers and determined they will run two per driver with no issues and this car has had zero issues. I will see if I can get the dyno sheets and post pictures of the setup soon.

 

They are 12.7 ohms. In parallel they are 6.35 ohms which is still considered high impedence. I have heard that some were running bosch 1600's saturated on PFC's without issue at ~4.5ohms.

 

that would be good info to get if ya can thanks also how the secondaries are wired parallel or series?

hmmmm so 6.35 ohms at lets say an optimal 14v 2.2amp that may be alright for the driver although i havent seen a definate answer as to the amperage capability of the PFC rumor has it 3a+ will fry em.... anyone with a more definate answer on that?

got that from the howard coleman peak and hold thread for the FJO inj driver.... torn between that and these injectors.

can someone give me the part # for denso donut?

 

i purchased the o-rings and the Denso ones did not fit like I wanted. i wanted something tighter and got these:

hey are you using your stock LIM with these ID2000 injectors?? thanks

 

xcessive lim

 

Can the PFC run a 550/ID2000 setup? The PFC injector settings will only run upto around 1600 cc in Datalogit. So how about that?
Does it need to be adjusted by the duty cycle then?

 

this is all really useful information, thanks for this.

Im going to be running 550/2000cc setup at 50spi base pressure to make the numbers i need.

Ill be honest and didnt know there was a limit on injector size, i have datalogit software on my pc and there wasnt a limit to what size injector i could type in, they said earlier that a guy was running 4x1000 secondary, id imagine he would have to put 2000cc aswell

Anymore info on that?

 

HELLO THERE
I DONT POST MUCH IN THE FORUM BUT I REALLY READ THIS ARTICLE AND I THINK IS THE FIRST TIME I CAN POST WITH A USEFULL INFO.

IM A COSTUMER OF GLEN AT AZRR HE BUILT MY ENGINE WITH A VERY AGRESSIVE PORT TO MOVE THE GT42, I HAVE THE XCESIVVE LIM WITH THE CJ MOTORSPORTS FUEL SISTEM ALONG WITH 6X1000CC ID1000 FROM INJECTOR DYNAMICS.

LET ME TELL YOU THAT HAVE 1000CC INJECTORS IN THE PRIMARIES IS A PAIN IN THE ***.. MY ENGINE EATS 12 SPARK PLUGS IN THE PROCEDURE OF ADJUSTING THE AFR AT IDDLE ABOVE THE 13 AND UP. WE FINALLY ADJUST THE PRIMARIES FINE. I THINK THIS WAS MAINLY BECAUSE I NEVER RECEIVED THE battery comp values WITH THE INJECTORS AND WAS A PAIN IN THE *** TO GET WITH THEM

BUT I THINK EVENTUALLY OR IN THE NEAR FUTURE I WILL SWAP THEM FOR A
ID725 CC TO RUN EVEN SMOOTHER AT IDDLE.

IM RUNNING A AEM ems and controls everithing just fine im shooting for big numbers here at leats 600hp and i dont think ill need 1000cc in the primaries for that task... my opinion go with whatever secondaries you want

i will post some pics either way that was what you were requesting i will snap some tomorrow that i have to remove the UIM to a litle fire i got deflooding the engine changing one of the sparks in the procedure mentioned before.

thanks and good luck

 

Wow, Glen should have gotten you the tables and with the correct values and I will guarantee that idle will not be a problem and will not have to switch down to 725's. Very sorry about this, if you have any injector related questions, let me know.

For future reference, here is a link to the instruction sheets which include the dead time tables for all of our injectors: injector dynamics instruction sheets

 

I'm personally not very familiar with the PFC, but I know of a few cars using PFC and 2000's and 4x1000's running perfectly.

 

One problem you will run into with the PFC that is unique, is that you cannot run lower than 1.8 mS on time at any time. Regardless of what you have programmed in the fuel table, the ECU just won't allow it.

 

Yeah, I've heard of that problem, but Glen has assured me that they have been able to get a clean idle with 1000's on primaries and correct dead times consistently.

Just for clarification, in my above post, I meant 4x1000's on secondaries on a PFC. I know RCCAZ1 is running this setup and has had great success.

 

We tuned a car on 6 1000cc injectors and had great success. No idle issues other than rich idle but when I say rich I am talking 13.5:1. Yes it is not easy to run below 1.8ms however with work it is possible.

I am running 6id1ks on my setup of course its with a motec but its a great setup for just about any aftermarket ecu..

Daniel, I have to say that I dont think my short comings is a reflection on the Injector Dynamic Injectors.

I did sent an email with dead times never heard you did not have then plus the aem map you started the car on has the deadtimes

 

of course glen im talking prior the days you send the map.

after that we receive the map we have a good starting point.... its true the injectors are great .
im just saying this cause eveyibody needs to adjust the fuel set up for what you want to do with the car, 6x1000 cc injecotr its for big numbers or course.

BY the way glen car is running fine, i cant get rid of that oil sweat in the manifold i thinking in the procedure of shipping the pan must receive a jit or something but everything else is a dream....

 

I read something about these injectors not being compatible with race gas, c16, vp, q16.

Any thoughts on that!!!

 

ID1000's and ID725's are compatible with all known fuels. The ID2000's are not compatible with fuels that contain MTBE, which are q16 and VPimport. Everything else is OK, including c16, c23, methanol, E85, etc.

 

To avoid any future issues finding deadtime data for the ID family of injectors we will have them on our web page www.azrotaryrockets.com by monday, so that every one has easy access to the tables.
