Air / Fuel ratio gauge

I prefered the idea of the innovate, as I've heard that the AEM's scale is a little too narrow, whereas the Innovate is programmable. Also as the Innovate gauge is sooooo thin, it is much easier to install, I got mine fitted into the position of the crappy facelift boost gauge. Plus it's pretty cheap if you get it from Dusty and MVP.

I'd like to know, what makes one better than another? What makes the innovative better than the aem for example? I'm not suggesting it is/isn't, just what makes a good one? ooops cross posted, think you've probably just answered that ben lol. do they all have an output for an EMU such as the emanage though?

 

oh and if you have an o2, do you really need an egt as well, are they kinda telling you the same sort of thing?

Lol, just not my style. sorry just realised thats not a photo of your car. Any idea's any one? clock space gone

 

The 'normal' spaces are:

 

- The two air vents

- Clock space

- Single, Double or triple pillar pod

- Triple pod that replaces the top glove box/air bag

- Remove the stereo and fit two large gauges

- Get a single DIN stereo and fit small small gauges in the spare din space.

- Drill a 'pod' type gauge to the top of the dash

 

Not sure theres many other options. Personally I'd go for a single pillar pod.

Open questions:

 

Do you need to consider the refresh rate of the gauge/sensor anymore ?

Life of the sensor ? - Do people consider this when using race fuel OR just topping up etc...?

Can you get hold of spare sensors ?

Do you want the range to go below 11:1 ?

Do you want data logging ?

Can you programme it ?

I'd want one that:

 

1: Could interface to an aftermarket engine management system (data out)

2: Had a reasonable sensor life when used with regular fuel

3: Used fairly standard, common sensors that are readily available and can be purchased separately without mortgaging the house

 

and maybe had a programmable alarm to warn when it's dangerous, guess an emu can be programmed to do this if the two are connected?

 

as long as the refresh wasn't ridiculously slow I wouldn't care so much about this.

 

afr of 11:1, thats very rich isn't it, is it useful to have one that can go below this?

 

do most of the brand names mention cover these features?
