I'm running an AiM dash.  Currently the car has a separate water temp and oil pressure gauges in the two bug-eye vents in the center of the dash.  Should I get rid of them and integrate everything into the AiM?  Or should I keep separate gauges?  The two gauges do feed data into the AiM presently.  But the dash is having to get rewired due to damage to the dash wiring harness - so, it's a chance to do it the way it ought to be, rather than simply accepting the current configuration.

 

Would be interested in thoughts from the experienced folks.

I would say to remove them. You can display the temp and pressure values on the dash if you want, but I would advocate for well defined alarms and to not every worry about the actual number.  I did a webinar with AiM on configuring the alarms and give some good ideas on how to set them

That's a good point.  I guess I was worried about overloading the AiM with hard to see mousetype when i could have these large visuals.

 

So, you don't see value in looking at the status of a temp guage, for example?  Or a oil pressure behavior at WOT?  What values would you set for these warning lights?

 

Is there a way to select AiM templates that's easier to access than the display?  From an ergonomics perspective, seems awkward to manipulate during a session.  is there a remote switch to select templates?

I could argue either side but once installed would keep both. I do want the easy and familiar visual of current status and how things respond to revs, temp, whatever and changes through a session or day. The data system is good for recording that to look at later and for screaming at me to pull out my credit card when it’s probably too late, but my old brain is comforted by familiar real-time feedback.

So hear is my thought. You can take all the things you would want to watch a gauge for and then make it an alarm. For instance, I have alarms (not in a Miata) for RPM over 500 and oil pressure under 10 psi, RPM over 3,000 and oil pressure under 30 psi, etc. You can set as many as you want. So, then if the RPM to oil pressure correlation isn't correct, you get a light. No need to watch it while driving (you have better things to do!). If there is no light, you can still go to the data and review it. Plus, you then have a record of the temps and pressures for the season and life of the motor to see if the pressure is dropping as the engine ages. 

You can also set yellow lights for warnings. Riding in the draft and coolant starts to get warm - yellow light and a message for what it means. Then you can work on cooling the motor and getting some air. Then their is a red light for too hot, you have to act now. Or maybe it's the last lap, you're in the lead, and it's now a trophy motor!

 

My general plan is to make well thought out alarms so that I can focus on driving and not trying to see what a gauge is doing. If it works for fighter pilots, F1, etc, it will work for me.
