hey guys,

this might sound like a stupid question but what kind of sensors do i need to buy when i buy my EMS for my IX to make it work at its fullest???

-thanks

 

air intake temp
MAP sensor
wide band
EGT

 

THANKS!!! also what comes with the kit when u buy it???

 

nothing, unless you get a set up from like buschur or other rep shops.

 

A few shops also give a decent tune set-up for your car when you purchase the EMS from them.

 

what is the difference between 3.5 bar map sensor and the 5 bar map sensor???

 

1.5 bar.

if i recall...

3.5 measures a 50 psi range. -14 to +35

5.0 measures a 72 psi range. -14 to +56


3.5 is plenty.

 

EGT is optional.. you dont really need it if youre running a wideband..

to my knowledge (not bashing you in any way shape or form just IMO)... i am not running EGT with my EMS...

 

no problem.....I need to get a wideband asap....

 

The pricing on these has drastically dropped in the last few months, I went ahead and opted for the 1313U w/Built in wideband. It's a good investment if you're planning to do your own adjustments in the future.

 

here is how i would rank the sensors in importance

1. map sensor w/rre or buschur map sensor block to mount to intake manifold
2. wideband
3. ait
a distant 4th: egt

do yourself a favor if you get the aem ems, buy the map sensor mounting block to put the map sensor as close to the intake as possible. if you dont, you have a pressure transport delay to the sensor by running any length of line. trust me, i have measured this & posted somewhere illustratin the transient boost delay associated with line length.

this transport delay can & will induce knock.

 

I can also vouche for the sensor delay time of placing a map sensor in various locations. The further you get from the ports, the more damped the signal is, but the more laggy it becomes.

 

What if you already had a wide band like Innovate/Zeitronix would you still need the AEM wide band sensor for the EMS , Also EMS does data logging so EMS + A/F gauge you wouldn't need an Innovate/Zeitronix right????

 

I would like to know also.

Trying to decide between 1320 with Zeitronix or 1320u...

 

No you can just wire them into the ems. I have the innovate and I just used one of the analog outs to the factory front o2 pin. And then just configured the ems for the right volts.
