Is there a way to get the AIM to register the fuel used etc? I haven't played around with it too much.

Not sure if I want to ditch the stock cluster, supposedly the street bosses have an extra module where the "lower" gauges would normally go in the center that registers which key is in the ignition for PCM tune selection. Maybe nothing happens if I pull it out, but not worth the risk right now. I do see that Watson makes a nice dash close-out kit, however

 

[VoodooBoss]

This makes it easy.

Exactly

Yes, it gives you fuel used per lap.

On my Aim I have it set up for % fuel in tank, and it is pretty close to the dash gauge.

 

[ArizonaBOSS]

Cool, thanks guys. I'll have to play around with the config a bit more. Easy stuff.

How did you do that? Is your AIM reading it from the dash or ECU?

 

[steveespo]

ECU should have fuel flow rate with clock, this is how you get miles to empty on the Info/Trip Odometer. If the AIM has that info and the fuel cell size it can infer remaining fuel and display it. I think

Looks like we want "M_FUEL_LVLMEAN" to display what's actually in the tank.

IMO....

Not bad! I need to re-use the stock dash however; we used the stock "skeleton" structure as a cross-bar for the cage, and welded the cage to that. So not really able to change that.

 

[blacksheep-1]

That won't lay over the stock skeleton?

 

[ArizonaBOSS]

I think the only weight we are going to get on the car is the final weight when it's ready for corner-balance.

Maybe I can sneak it into the race shop next week and get a "before" weight.

Here's what I'm thinking (gross estimation) on what could be done weight-wise. Pardon my notation, it is a little backwards from what you might normally think.

For reference/follow up; the car came out at 3306 lbs without driver weight, and I haven't even done some of the reductions shown in this spreadsheet (aluminum DS, wing, lexan, ac compressor removal, etc)

Update: This isn't present in my list of channels on AiM, still haven't found something that works. Using stock fuel level gauge between sessions.

A couple extra videos from the last races of 2013:

You have P_FUEL_USED. If one doesn't already exist, you can just write a custom math channel with the static beginning fuel load and then subtract P_FUEL_USED to get a "fuel remaining" value. If you are a real propeller-head, you can probably write a channel that returns "laps remaining before empty."

Custom AiM Math Channels:

OR, take the data you have already collected to get your racing burn rate and do the math up-front to determine how much fuel to put in the car for any given race/track. This is actually better, because you only want as much fuel in the car as you need anyway. Then fill to that level before your race and don't worry about a gauge.

I'll try that out--thanks! It will probably end up being the custom math channel; haven't played around with the custom stuff too much but that tutorial should help. The "historical" burn rate is about 4 gal per session, so I'm not flying truly blind or anything; it would just be nice to have a more exact figure each time out.

Did you get the Master Cylinder Pressure data figured out?

 

[Jimmy Pribble]

Did you get the Master Cylinder Pressure data figured out?

I'm getting there. I did collect some quick street data with the 302R configuration before Polar Vortex 2014 hit (only lasted one day for us) and I'm still getting my head around it. Right now I am mapping the 2012 Mustang AiM config against the 302R AiM config on a spreadsheet, because they use different channel names for the same things (Why AiM, WHY??? ) and adding plain names. There are some channel names that I can't figure-out at all and there is not any standard (apparently), nor any documentation for either the 2012 Mustang or 302R config.

My intention is to get everything together and start a "How to get started with an AiM system" thread in the how-to forum. Then the AiM people can come together and help solve the mystery channels and share tips, tricks, and maybe even math channel formulas and track data. We can geek-out on very specific AiM and Race Studio stuff. I'm no expert, either, but I figure we will be soon enough.

And yes, it does appear that the brake pressure channel works fine. I'll do better testing soon (I get TracKey on Saturday.)

That thread sounds like a good idea. I'd be happy to participate.
I can make pretty decent sense of all the data channel graphs, but I did order this book (recommended by a couple friends at SVT) to help even further. It should arrive soon via Amazon.
