Picture Request- Injectors Resistors placement?
So my buddy brought me a "Ultimate Fuel Injection Kit" from the RX7 Store.net. As usual he buys the crap (not saying the kit is crap BTW it looks ok) and I'm the one who has to figure out how to install and tune the stuff.
He is running a Apexi computer and the kit came with little resistors to install. With the Apexi computer do I need to install them and if I do, can I put them on a plate between the secondary injectors? Or do they need to be mounted away from the engine heat?
I assume that the injector resistance is different for some injectors. Here is the link for the injector kit.
Ultimate Fuel System 93+ RX-7
The parts bolt in very well and I think I found a nice place to install the fuel pressure regulator.
So does anyone have any pics of where they installed their 4 little resistors? Is there a better way to deal with the different injector resistance?
Any why don't people just install injectors with the right resistance? Do the other injectors "work" better?
I wish I had some idea as to what I am doing. He was embolden when I put in his REALLY CRAPPY turbo kit. What a cheap skate. Now he wants to increase the boost on a tired old engine and I told him he is already running lean. I put up with it because I get to learn on his crappy car and then do mine the right way! ( I went with a IWG Turbo kit from turblown AWESOME! but still installing)
Thanks for all the help guys!

[QUOTE=JTurtonRX_7;11809924]this post hurt my head and made me sad[/QUO
So I take it that you don't have a suggestion on where to install the resistors or a pic of it.

Basically, the resistors are used with the old EV-1 style injectors. You will need them with the Power FC. The downside to using ev-1 vs the latest EV-14 (Injector Dynamics) style is that the ev-1 will run slightly higher injector duty cycle %'s. As well as idling is not as smooth and easy to tune using the EV-1's because of the older spray patterns.
As for wiring locations I prefer inside close to the ecu. But its up to you.

Very helpful. Thank you. I will mount them near the ECU making sure the little heat sink resistors don't get near anything that it will burn.
Searching provides so much information in such a dizzying array that it's hard to get some basic information. Also there are so many different set ups it gets confusing fast to someone who is not used to aftermarket/modifying stuff.
I wonder how hot the little heat sinks in the resistors get....

Why people continue to use 1970's technology EV1s is beyond me. I can't tell you how many customer's didn't know any better until I showed them the difference in how a car runs with modern injectors. You can use EV14s with the RX7 store fuel system. Just order them in 60mm height with a 14mm top and bottom oring. The rest of the fuel system is fine. You'll have a much better running car and don't have to mess with resistors.

No because they are high impedance. The reason you need them with EV1s is because they are low impedance and you can burn up the injector driver in the PFC without them. Somewhere between the ecu and injector there has to be a resistor. Or some people run an FJO or AEM injector driver, which does the same thing. Running a resistor to an injector actually reduces the total amount of fuel it can flow ultimately. Personally I would sell the EV1s to someone who has an older application better suited to them and get EV14s.

Having said that the injector dynamics are great but they can get expensive....*now is the time for someone to chime in with the* "well then, you shouldn't own an fd" bs. Some people are going to scold me for saying this but if you go on ebay there are some decent competitors to ID. You can pick up new ev14 100cc-2200cc injectors for half the price of the ID but you still need to source some adapter/hats (from ID or FFE).
Just my 2 cents

You still need them with the aem v1 if you use ev-1. Unless you are running stock injectors. The new ev14 better for obvious reasons an I too made the mistake of buying a kit like that...I didn't know any better because I was new to the game of rotary.

The reason im going to "scold" you, is because you have no idea what you are talking about. Can you tell me why tuners like me pay the price for REAL Injector Dynamics injectors? No, I guess you couldn't could you? Oh, it says 2200cc and its made buy another company soooo, its the same thing. Smh...

I love how in a few sentences you manage to insult me, ask me a question and then answer your own question, all with out explaining why My post was wrong.
I don't come on these forums to insult and belittle people for amusement. And to answer your question tuners prefer Injector Dynamics because of how well they preform and their reliability. They are partnered with Bosch Motorsports and have put a substantial amount into R&D.
Now Bosch motorsports is a business, and they supply/sell EV14 injectors to a lot of manufacturers which utilize the same design as injector dynamics (because they're partners). They are not built to the same tight tolerances/specs as ID but they are a great option=which makes them a competitor.
Do everyone a favor, take a deep breath and relax. Lets not be hostile.

Just so people know one of my dealers had a generic set of bosch 2200cc injectors and did a back to back dyno test vs the ID injectors. The ID injectors make 33 more at the wheels on 20B! This was also tuned and confirmed by globally known tuner( holds most of the 2JZ records etc).

buy the id2000 no resistors plug and play same plug as OEM
the work just perfect
If you buy them at their web page they came you the o-ring adaptor and the work perfect for the fuel rail that you are buying
I was at the same stage than you probably 6 months ago , and I sold the Bosch 1600cc and bought the ID2000
