I bought a Blitz AF Meter a few weeks back from Dino (japandyno) in Japan. He told me that I would need a second one as the zed usually runs two AFRs and sensors. I've not been able to find another secondhand Blitz one for decent money so when I spotted these 'Multi checkers' from APEXi and JECS I figured that I might be able to utilise them as the second AFR along with their other functions (shift light etc)

 

I bought the JECS one from Dino and the APEXi version from another company Japan, they seem to have some pretty good functions so I snapped them up.

 

Does anybody have experience with either of these systems?

 

 

Here's some info:

 

The A'PEX-i Multi-Checker features:

 

* Monitors all various aspects of NISSAN vehicles using the diagnostic signal.

* The Multi-Checker is a valuable diagnostic tool designed for most NISSAN fuel injected automobiles. The unit monitors and displays a wealth of information and is unmatched by any other similar diagnostic meter on the market today.

* The unit displays vehicle speed and engine RPM both in real-time and peak hold modes. Injector pulse duty is displayed in percentages with a peak hold mode. The airflow percentage, ignition timing, horsepower display, torque display, and air-fuel ratio display add to its impressive list of functions.

* The unit can also alert the driver to recommended up-shifting points and will sound an alarm as the air flow meter or injectors reach maximum capacity. A large, easy-to-read display clearly shows all functions and is back-lit in orange for easy nighttime visibility. The display can also be set to a bar graph mode for quick and efficient monitoring.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

I want to use it for its AFR capability but figured that the zed usually needs two sensors and two AFR gauges so I also bought a JECS version to go with it

Also known as Apexi multichecker but this here is like the Nissan Checker with separate amp unit.:

Can also be used in many JDM cars.

Very nice unit and EXTREMLY RARE

Blitz's A/F Analyzer ranks among the best in air/fuel meters yet with an affordable price tag. Each A/F Analyzer comes with a fast microprocessor box and its own heated wide-band O2 sensor for unparalleled performance. The five-wire wide-band O2 sensor offers a very wide range voltage readings which gives it greater resolution compared to stockers. This enables the unit to more accurately monitor air/fuel ratios from 9.5 /1 to 16.0 /1. The A/F Analyzer air/fuel readout is displayed on Blitz's Full Auto Turbo Timer (FATT) LCD screen. A warning mode is also incorporated into the unit to alert for lean conditions. The user is able of preset the air/fuel ratio that will trigger the warning alarm. An audible beep will sound off and the LCD display will turn from green to red warning the tuner or driver of the unsafe air/fuel ratio. Considering most racers are keeping their eyes on the track the sound will immediately signal the driver to let off the gas pedal preventing the engine from blowing up. Blitz's FATT meter can also be used as a turbo timer and voltage display meter. The FATT meter automatically calculates and adjusts the time needed to properly cool down the turbo. Battery voltage warning for high and low voltage is also incorporated into the unit. The user sets high and low warning modes to signal a voltage spike or excessive draw.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

any advice on fitting etc would be much appreciated.

 

I'm looking at fitting the AEM EMS sometime this week, I've assumed that this is compatable???

 

 

cheers

Any ideas?

Personally i think you've gone the harder and more expensive route.

 

The units you've bought don't wire in to the AEM ECU, so your mapper would use their independant readings on the units when mapping.

 

You don't need 2 units to run 2 sensors, assuming the throttle bodies are correctly set and with the balance bar, each side shouldn't see any significant difference.

You can run 2 sensors on 1 unit by adding a toggle switch as really once these have been used for mapping the car, you shouldn't see much change in the ratios.

 

If it were me i'd sell what you have, buy a new AEM EUGO controller for about 150 quid, it comes with 1 sensor and harness to plug into the AEM ECU and a really usefull gauge with warning facility.

Again by adding a 2nd sensor (if desired) and harness approx 50 quid in total which can be run of a toggle switch for mapping and time to time check to ensure both banks are even.

Cheaper, easier and more tidier :thumbup:

 

You can also run through the AEM EGT and intake charge temp sensors quite cheaply, the latter telling you how effecient your intercooler(s) are or arn't.

I was tempted to have the JECS one from ebay

 

Sorry I cant help with the fitting bud

Thanks for the info fellas, much appreciated :thumbup1:
