Torque PIDs...Take 2

I'm willing to help once I have a few moments...What is the Forscan PID showing...total number of misfires or per cylinder? The challenge with this is its best to capture the serial data when actual misfires occur so you can see the binary results. This is challenging since Misfires occur so quickly...or not at all if everything is running perfect.ShoBoat said:
The misfire gauge is interesting to me but that might be a problem in itself. I find a lot of them interesting and so I'm running a lot of gauges. I wonder if there is an upper limit which should be avoided. I also wonder if a gauge that's on a screen that's not being displayed is still adding to the PID load. Got to stop adding gauges. I'm turning into a gauge junkie!

The gauge is a running total of misfires during the current drive cycle. It's happened once to twice that I had a few on startup. And when I started FORSCan it registered as 2 as soon as I started the log. So as long as you can get it to report one we should be able to figure it out.
The misfire gauge is more than just interesting! It gives you an insight to how the car is running. Fouled plugs? Gaping incorrect? Bad wire? Oil getting into the intake? You can tell a lot from it.

Yes this is absolutely true! However I would just like to make sure that Larry realizes these are scanned sequentially and if you have 100 PIDS that is probably the Max rating of the MX and its a per second number. The implication here is that you would only get a reading of a single PID every second. More than fine for things like temperatures but if you want some degree of resolution on your Knock number then I highly recommend you use as few PIDs as possible so you don't miss events. This car can throw massive a lot of data on the CAN bus at one time and could overwhelm Torque pretty quickly as we've already proven it isn't the fastest thing in the world.SHOdded said:
Now what I don't know is how many it is actually reading at one time...if its just what is on the screen or scanning all of them that are in the list every time. I do know the gauges don't update unless you are actually viewing them...I'm not positive that means they aren't still reading them in the background. I do know that if you are actually logging with Torque (I wouldn't bother...its too slow) or you have an "alarm" set up on a PID then it reads them all the time. So use that sparingly if you do.
Just my 2 cents...

I've contemplated this but just can't bring myself to do it...It would obviously be dumping fuel in the cylinder but if you are talking idle I "doubt" it would hurt much but really don't know. Cars obviously lose coils and plugs all the time so this happens and I doubt you will be rebuilding your motor because of it BUT I'm paranoid.ShoBoat said:
