At the Supra Vegas meet, I had a debate with Saad about running a warning light in your Supra which flashes if you go lean under boost. I have one of these LED's in my Supra. He shortly thereafter had some fueling issues which caused him to go lean and he didn't know about it and he lost a head gasket.

AEM has come out with something even better than my LED. They released A gauge that shows any parameter in the EMS, which will also do a warning flash and audible alert based on any settings you want. This gauge is completely programmable and will allow us big dogs to actually see the boost we're running because you can set up the peak to be as high as your MAP sensor reads.

Here's the details..

Very cool!! Hmm, Chris, you have me thinking about selling my greddy gauges and fjo and just going with the AEM unit. So I'm assuming it's the $274 plus all of the gauges you want to display?

edit; just realized the $274 is basically for the gauge setup ;)

Chris

We were just talking about something like this last week, If i had an audible gauge on that last run, I woudl've known first 3 gears was running 13:1 and it be running still today :eusa_ange

Is that price per gauge? or all 3?

You can display everything you want on one gauge for $274. If you want to display two pieces of information at the exact same time, you can buy two and daisy chain them together. However, you can just use one, set up 2 or more parameters to look at, flip back and forth between them with the buttons on the front. You can also just get one gauge, simply look at one set of parameters, and set up a warning on the other set of parameters which will pop to the front if it enters a warning mode.

I burned up a motor due to starving a pump a couple years ago. So I installed a simple RED led which was a real pain in the ass to set up. Since I installed that it saved my motor on several occasions. One time I had one of my three pumps go weak on me and I had to lift at 13.5:1 A:F mid track. One time I had a rubber fuel line in the tank rupture on one of my pumps, same thing, I lifted. I had both of these happen on mutliple occasions.

These gauges are a much more convenient, visually inform you of warnings and also provide an audible way of hearing this information. I also look forward to really seeing what boost I'm running. And the boost gauge will be very very accurate.... as accurate as the MAP sensor.

Take care,
Chris

Well that is easy to do when driving on auto down the track. A monkey can drive an auto into the nines, I've just never seen one with blond hair and plays poker:)

If you look down when driving a 6 speed you will have other problem, most of them being walls:) The red light however is a good idea, but it would work for you mostly at night.

By the way, I did not blow up my motor. I just hurt the head gasket. The head and bottom end were perfict. What does that tell you about my motor after going to 16-1 afr three times in one run down the track?

Well, that's pretty damn good to lose a head gasket and not hurt the motor. It usually doesn't work that way. The title is a bit catchy.... but I prefaced it in my first post with the head gasket story.

Get a gauge Saad. :)

Chris.

What about senders which senders well work with these gauges?

What do you mean senders? These gauges read the parameters out of the AEM EMS. The AEM EMS get's it's data from the sensors in your car. Does that make sense or am i missing something.

Chris.

Well what about oil, and fuel pressure? Not many cars have a fuel pressure sender stock, and most oil pressure senders are not very accurate.

Ah... just get an AEM oil or fuel pressure sender. I'll need to verify if the AEM gauge can display these results and alert warnings for them, but I'm pretty sure it can.

Here's a page with the sensors. The sensors from AEM are all very accurate.

Chris if you could check to see if the guage does indeed display any info I want such as oil and fuel pressure that would be great. What is the most amount of channels this thing can monitor at the same time?

I want to see a guy with a 9 sec car that looks at guages running down the track. If you go fast or make big power, its going to break. There is not a guage thats going to save anything.

Chris, that statement is a bit ridiculous. My Supra runs 9's easily and I've had a bright red LED save my motor several times.

With the gauge, You have 9 full seconds to see a flashing light in your face and hear a loud warning sound. I suppose if you put the gauge down low on your dash you wouldn't see it flashing red, and If you covered up the warning sound you may not hear it. To be used effectively, you must put the gauge where you can see and hear it.

I can't believe you guys haven't been using the red LED's like I have done for the last year. I had a fuel pump line rupture (red LED and let off), I've run at slightly below 3/4 tank and starved one of the pumps due to fuel sloshing (red LED and let off). One of my 3 pumps was weak (70psi) and near the top end the car went lean (red LED and let off)

I suppose if you don't want to know these things that's your call. Information is key. The driver can react to a bright red light and noise just as they can react to the car getting squirly.

Chris.

kinda like this one.

well, i guess i'd rather have Kean looking at the track and the tach rather than looking for lights, flashes, no lights, and sweeping guages. Our car is vey simple and attributes to it's consistency.

How are you guys rigging up these safty LED light to say you fuel pressure? Is it throught the AEM? If so what is the best was to configure this and wire it up. Thanks Ron

Hey, that works. Anything is better than nothing.

I am going to get an AEM serial gauge and mount it to the roll bar for a couple reasons. With the LED as you and I have done, you can only set up the warning for one condition. With the gauge, you can set it up for a drop in fuel pressure (which would precede the wide-band stating you're going lean), you could trigger it on an oil pressure drop, A:F drop, boost creep or other critical malfunction. You can also trigger a warning only when multiple conditions exist (e.g. high boost and weaker fuel pressure) These warnings would automatically trigger the sound, lights and show the warning condition on the front of the gauge. The other benefit for my car is that I can program the max boost on the gauge to 45psi. That way I can actually see what boost is since most boost gauges only read to 28psi.

You can also program the color of the LED's to behave in any fashion (e.g. Green for a good condition, Yellow and Red for a bar condition). This is in addition to the warning flashing that will occur when you exceed a threshold.

If you're going to use the AEM and LED's, I use high side outputs and wire an LED into one of the HS pins. Then I configure the outputs in the AEM software. They are a bit tricky to get to work correctly and are not very clear or intuitive. Basically for me they work backwards of what I would expect. I also have one set up for a shift light. My dash lights up orange when it's time to shift, and red if any problems exist.

I did this off of A:F ratio not fuel pressure however. The AEM EMS outputs will not allow you to program a boost and fuel pressure level to trigger the HS output. The AEM Serial gauges will do this very easily and it makes a whole lot of sense when you look at the software.

I am on AEM's Consortium Review Board and I fly down to their business to review many of their products before they come out. So a bit of my feedback is built into the AEM Serial Gauge software they are using. I definitely think they've nailed this one. Very easy to use. Completely versatile. And provides the features that I feel our customers need the most.

Take care,
Chris.

yes, an idiot light is a great idea. so you can use any of the vacant pins on the ecu harness for the HS output and assign any one of those wires to address a light. and itll use any parameters you designate to send a signal through your self-designated HS output pin, right?

arent there features on the AEM thatll allow you to create a hard fuel cut if it runs too lean? i know you can obviously do it via boost level... but i didnt pay any attn if you could set the boost cut to trigger due to low AFR or any other parameter you designate, such as low oil pressure or fuel pressure.

btw, you SHOULD be able to install electronic sending units, or perhaps a Hobb's switch and wire it into a vacant HS input for the EMS and calibrate the EMS to recognize these signals either as analog or pulse/on-off, right?

what do you think?

Kinda like a laser detector, it's probably a little to late when the light comes on. Building all this safety devices are cool, they also add reliability issues and possibiblty of causing more problems. Please think about reverse engineering, when your safety device breaks.

Gauges should be here next week for those that want em. Let me know. They were exhibited at Sema this year as well for those that got to check them out. By the way, AEM won the best US manufacturer award at Sema.
