Fast EFI Fuel Injection Components and Installation

[@tokuzumi1]

I hope this kit comes back in stock soon.

[@gav240z]

Be nice to have a system that replaces the ignition system also. Coil on plug set up etc.. is the ECU capable of this? I understand it's not in the kit, but does it support extending it?

[@chriscraft77022]

are you from the actual website? i just got a 280z yesterday.. getting an order ready. is that your company or are you just using the name for youtube?

[@viperpartsdepot2993]

We are from Zcardepot.

[@jamieblasingame969]

I plan on later this year / early next year installing on my 83. I recently got it going again after basically learning all the Datsun EFI bits. They moved stuff and changed almost every year :)

[@zcardepot4854]

Every year the cars gained more electronics and controls which make things more confusing! The FAST system simplifies the EFI and uses all new sensors which are more readily available and cost effective.

[@jamieblasingame969]

ZCar Depot Yes! Even the seatbelts are diff in the S130

[@neticz7]

Does it matter which injector plug goes onto a certain cylinder?

[@zcardepot4854]

It does not. Batch fire so all injectors pulse at the same time.

[@neticz7]

@@zcardepot4854 awesome thanks for the reply

[@dean4318]

Are y’all still selling these? Any clue if there will be a restock soon?

[@erickesparza6352]

I have a 83 maxima. Its has a l24e, will this kit work with it??

[@luisrgamez]

Can I cancel the idle screw in the throttle body and the ECU will adjust the idle by itself? I saw on other video a step on setting up the ECU that a bar on the handle needed to be set up Thanks

[@uzalonso7356]

When will these come back in stock? Thanks!

[@zcardepot4854]

We can only seem to get a limited supplies of these. we get 4 or 5 at a time and they go quick. Best thing to do is sign up for notifications on the website. Thanks.

[@jcabral1986]

Any recommendations on order of fuel injector plugs or do you just pick any six?

[@TheLOAF90]

Unfortunately, the link to the product does not seem to work. How much will the product cost and will it improve mpg substantially? (I drive 45 miles to work one way & fuel efficiency is more important than power)

[@zcardepot4854]

Link fixed. We have not tested the system extensively for MPG changes. I would guess picking up 10% in fuel economy would be fair to say. If the stock system is all working correctly you might not see much difference in fuel economy unless you lean out the cruise AFR on the FAST system. Changing the idle, cruise or WOT air fuel ratio target only takes about 20 seconds on the handheld input device. If this target were leaned out in cruise mode I would think it is possible to pick up 3-5 mpg (maybe more) over a good working stock EFI system.

[@zcardepot4854]

The air/fuel ratio can be altered on this system to run as lean as you would like at cruise speeds for optimal MPG.

[@discostu46]

Nice system. Is the idle speed screw on the throttle body still used for base idle and then the IAC makes corrections for, say, the A/C kicking on or allowing fast idle during cold start-ups or does the IAC completely control all idle conditions? Thanks :-)

[@zcardepot4854]

The IAC will control all of the idle functions and does have compatibility with A/C. In the setup the computer will allow you to set the throttle blade at the ideal location for the IAC to work. There is a cold start fuel additive that can be custom taylored.

[@zcardepot4854]

IAC will control all idle. You select a target idle RPM that it will maintain. So if you turn A/C on and it pulls the engine down, the IAC can open more to increase idle RPM back up to the target RPM.

[@discostu46]

@@zcardepot4854 Thanks for adding this more recent comment. That sounds great!

[@interdigitate]

@@zcardepot4854 Hey, if my throttle body doesn't have an idle speed screw is there another way I can adjust the base idle?

[@zcardepot4854]

@@interdigitate Basically need to create a small air leak somewhere in the intake. You could run a basic air bleed valve off of a vacuum port or Some have drilled a small hole in the throttle body blade.

[@ryderamos]

If using the stock injectors, is an injector resistor necessary?

[@zcardepot4854]

We have usd this kit with stock injectors (no resistors) and not had any problems.

[@ryderamos]

@@zcardepot4854 thank you

[@ernestomejia110]

Do you need a cam position sensor or a crank position sensor?

[@zcardepot4854]

Neither for this system, it is just fuel control.

[@zcardepot4854]

No cam or crank sensor needed as this is a fuel control system only.

[@AllenHebert]

I lost my instructions, can you make an electronic versions of the written instructions available here?

[@joeswheat]

How about fixing the link or remove it?

[@timgorham6265]

How do you connect the green fuel pump relay wire from the ECU, given that the stock fuel pump relay is eliminated?

[@zcardepot4854]

On some years the stock fuel pump relay can be retained as it is not a part of the ECU and wiring. The green wire from the FAST ECU is a signal wire to turn on the fuel pump once the ECU sees power. It is preferred to run the green wire to a relay and then to the pump.

[@200sxxxxx]

Just a couple of questions. How would this handle a turbo, could this be use in itb's?

[@zcardepot4854]

Will not work with turbo. Can be used with ITB's but will need a common manifold pressure connection.

[@zcardepot4854]

Cannot be used with boosted applications. Will work with ITB's, just needs a vacuum reference for all cylinders.

[@timothysereno409]

Is there a kit so that I could add a turbo to a 280Z L2.8 engine?

[@zcardepot4854]

We are working on this kit. Looking to have manifold, intercooler (all piping) and engine management done by the end of 2019.

[@zcardepot4854]

The EZ EFI will not work with boosted applications.

[@josetoaster4198]

any recommendations on where to exactly mount the 02 sensor?

[@zcardepot4854]

Within a few inches after all of the pipes converge is ideal. Also mount the sensor coming in from the top or side, not the bottom of the pipe.

[@zcardepot4854]

2" - 8" past where all of the header pipes come together is ideal. Mount the sensor towards the top of the pipe so that it does not hold moisture.

[@theguy9234]

This would be great on my 240z with a 280z motor. Pretty sure I've got most of the 280z parts for fuel supply

[@jasonbuenviaje6250]

How ez to convert this on 240z? What will be the requirement.

[@TheFelepeno]

Well, a 240z has carburetors so... you'll need fuel injection lol.

[@zcardepot4854]

You will need the induction system from a 280Z/280ZX (intake/fuel rails/Throttle body) along with a high pressure fuel pump conversion.

[@craigfrancis9578]

I want a conversation kit that could replace a carburetor for 1600 to 2000 that can just sit on the existing manifold

[@zcardepot4854]

This kit is only for port injection manifolds. We do not have a kit for bolt on replacement for carburetor. Thansk.

[@zcardepot4854]

This sytem does not work with a turbo. It can only be used with a 1 bar MAP sensor which cannot be used with boost.

[@craigfrancis9578]

The reason i want the conversion kit because am getting alot of cars to by and fix them to sell but i cant get the carburetor replacement part because the cars are old so if i can buy this kit i can put it on any car with carburetor that will be a win for mee

[@jad67jd]

I have a non-trivial model 1982 ZX. How much?

[@zcardepot4854]

This kit will work on any 75-83 datsun 280Z/ZX (non turbo). Replaces all of the EFI wiring and sensors for a complete EFI conversion.

[@jad67jd]

ZCar Depot Excellent. But how much please?

[@zcardepot4854]

$1299.00 zcardepot.com/fuel-injection-retrofit-kit-fast-efi-280z-280zx.html

[@zcardepot4854]

No cam or crank sensor needed. This sytem is fuel only, does not control ignition.

[@matthewdavisfamily]

Any recommendations for an ignition upgrade as a companion to the fuel injection upgrade?

[@andrewmason830]

fix the harness and make a real set of institutions make it clear and ez

[@michaeltoomey6542]

Anyone else try this out?

[@sharonfarmer7494]

is there anyway to add 2 step

[@zcardepot4854]

This sytem is fuel control only. Two step would be in the ignition system, an MSD or other aftermarket ignition can do that.

[@zcardepot4854]

Not with this system.

[@hollissmith5467]

HI I just put a 4blb on mine for about 475 much better

[@zcardepot4854]

Cheaper yes.
