Sounds more like what he wants is the RPM sweep window, Change time along the bottom to RPM and RPM up the side to brake %.
That way you can drive though each gear simulating a more realistic road load.
As RPM raises so will load. Obvously youd set 5th gear as your gear ratio and every other gear is going to read massivly wrong for RPM but would work.
Or just back to one of my orignal requests for a Brake load based on car weight and manual brake control in %.
You can semi do it using the brake test in the settings to apply a manual ammount of brake %.
Or looking in the plugin control there is a value in there for setting brake stuff so I could do it though a plugin just dont have much time for the next week with Americarna work and there last week rush with every one that leaves it to the last week.

You could re-set the calculated rpm to be in 5th (I am currently doing testing in 2nd), but why not just have load versus roller speed? (After all, that's what actually happens through aero drag - load goes up very quickly with road speed.)
So if using the rpm sweep window as the basis, change the bottom time to roller speed, and rpm up the side to brake %.
You could map the load graph to replicate aero drag, and have a base load that's always present to represent rolling drag. (And/or you could increase the base load to represent inertia.)
I think that this would work really well.

Problem being software doesnt have speed value with in it and everything is built around RPM so would be a lot of work to add it in that way from what I understand.
Iv been meaning to update the speed/distance plugin to add stuff for hub dynos.
Instead of making a new plugin for this function your wanting ill add it into the speed/distance plugin since I was also going to add speedo calibration stuff (To learn brake control stuff from plugin system). It will hold the speed you set so cars with touchy throttles dont have issues holding stable speed while adjusting speedo.
Wouldnt be much more work to add another mode in there that has setting such as. Increase load by x% per xKPH with starting load of x.
Should give you the sort of feature your wanting for tuning per gear enrichment. Wont give any dyno graphs tho.
I dont understand areo stuff well enough to let you just enter the drag ratio. And dont understand well enough all the different retarders to let you just enter weight of car as the base load.
But it is something that could be expanded on and added with research.
Speed/Distance plugin is open source so any one will be able to add to it.
But you can set a gauge to show roller speed? But it's not in the software?
Thats Roller RPM. If thats what your talking about when you say roller speed.
Any thing speed related is done with in the speed/distance plugin its taking the RPM from with in YourDyno. Converting it using the entered roller measurements.
Yes, I see what you mean. Roller rpm is fine.
Any Updates Julian?
Unfortunately my wife has been ill - in hospital now, and in and out of hospital over the last four weeks. However, I did manage to finish the remote control for the dyno fans - four high-current relays providing mains outputs.
1- radiator cooling fan
2 - engine bay cooling blower (uses a hose)
3. - fan behind car
4 - car exhaust extractor
I have also set up a thermocouple input for EGT, and two MAP sensors for boost and exhaust back pressure.
My wife's mum has come to stay for a while to help around the house and so I am hoping to get back onto the dyno in the next few weeks.
Sorry to hear that. Wish both of you the best.
Have missed seeing your updates.
Sorry to hear that, Julian, hope she gets well soon!
Hope everything goes better Julian!
I seem to keep on blowing up GM 3-Bar map sensors. I am using one for measuring boost and one for exhaust back-pressure. It's the exhaust pressure sensor that keeps failing. Highest back-pressure I have seen (in front of turbo) is 2.5 Bar, so max pressure shouldn't be an issue. No heat gets to the sensor - long hose and no flow. All I can think of are really high pressure waves (3 cyl).
Anyone experienced anything similar?
And I have an answer!
I cut open one of the failed sensors, and it is full of water drops Hmm, I definitely need a good water trap, or to use a sensor that can cope with fluids.
Saw your orignal question on my phone and just got home now to answer it on computer lol.
Was going to ask what water trap system you have.
One I have looks like a big monsoon jar with 2 fittings on the lid.
one fitting has coiled copper tube that you connect your pressure line to.
Then other fitting has a small carbon filter off the top before going into map sensor.
Thanks mate. Pic?
