Bugs and Feature reqests

Hello,
there is no logic for it to be a TPS issue, when i see that the EMU is registering the votage change, meaning the TPS works. I can see the TPS showing 0,6+, even 0.7+ volts on the EMU, but the IDL register still shows green meaning the EMU thinks i am at Idle. If it was a worn TPS then the voltage would have stayed the same. I will experiment by moving the TPS position and adjusting settings, so that the IDLE voltage is at least 0.65v and see what happens.

just log the raw TPS voltage at closed and full throttle then enter those two voltages directly into the tps calibration. Make certain your engine doesnt have a mechanical idle up mechanism/actuator on the throttle body, some engines have this and it will cause all sorts of problems.

Ok the issue ended to be a bit more complex. Actually i though that IDL showing green means ECU detects car is at idle with No Throttle applied, but apparently this is not the case. IDL illumination means that the car is under IDL control. And the IDL control stops as soon as the IDL control max RPM are reached, which explained why the light stayed illuminated until 0,7+ volts. This was the moment when the RPM got past 1500, which was my IDL max control RPM However i would have found this easily, if it wasn't the problem with injectors cutting off on light cruising. This was a result of Fueling Resume being put at 1200rpm and at the same time IDL control max RPM were 1500. This makes a big mess, so don't do it I have put the IDL max control to 1250 now and the fuel Resume is at 1300, which has solved completely the issue that i was experiencing.

"When i change the X Axix on Oil Oress. or Oil-temp or Fuel Press. or Fuel Level it change it to all, not what i want."
+2


I think, this should be independent.
Otherwise for me it is not possible to enter the correct calibration data.

For example, my sensors are:
Oil-temp is from 0-160°, 0-5V exponential
Oil-press is from 0-10bar, 0,5-4,5V linear

So it is impossible to get linear and exponential characteristics in one chart.
If I change something in the oil-temp chart, oil-pressure chart is also changed and the other way round.

you will need to leave the x axis all linear and then adjust the individual points up and down to match the correct calibration on each graph

Thanks for the answer. That did the trick, but it is not very exact.

I still think this has to be fixed.

Is it possible to get a seperate strategy for water/meth injection?

I need to adjust fuelling when the water/meth is active, I could use the Nitrous for this but I am running Nitrous.
I could use the 2nd table but I am using that for LPG so cannot find any other means of adjusting the fuelling purely when the water/meth injection is active.
I just need to be able to say when a preset input receives a signal, reduce fuelling at a certain part of the fuel table by a set amount.
I would rather not adjust my fuelling and then rely on the water/meth injection kit to work but instead adjust the fuelling for when the kit is actually active.

I can't think of any other setting I can use for this but certainly open to suggestions.

Thanks,.
Edward.

Table switch?

You could build an entire table for VE2 and use it for your water meth.

When it activates, it signals the EMU to map switch

Hi,
I'm new to EMU, but so far so good.
I think it would be great to have keys for increasing/decreasing fuel and ignition timing separate.
When I'm tuning on a dyno, I need to click on the map I want to edit and then press + or -
Let's say I would be able to set: + = increase fuel, - = decrease fuel, pageUp = increase timing, pageDown = decrease timing
Also, It's good to have permanent correction which user can change while tuning, and then just apply on current cell with a press of a button.
This doesn't require to press +/- multiple times on each active cell, but just change the correction for each new cell and apply.

This method is used in DTAfast ECUs for example with the dyno box, which has it's pros and cons.
But I think this is easily achievable on just keyboard as well.

I hope I explained myself clearly.
If this is already possible, or there are other, better methods of live tuning please let me know.
Thanks

Can I get an answer on the dedicated increase/decrease keys please?
Also, it would be great if the cells that I adjusted, would be marked, so when I'm tidying up the map, I know what cells to interpolate between.
Thanks

Hi,

Thanks for the reply.
Unfortunately I use the 2nd table for running on LPG so 1st table is tuned for petrol and then when the vehicle switches to gas it switches to the 2nd table map.

Is it possible to add a second MUX switch?
Since we can use any analog input it seems its software related and pretty easy to do it, so we could have 6 switch inputs using only 2 analog inputs

and maybe it's possible to add more switches for "one MUX switch", like change it from 3 to at least 4? then, if there could be "2nd MUX switch" we can even get 8 switches on 2 inputs.

unless there is some other way being prepared, like "CAN BUS switch panel" - is it possible to get more info about it? and if it is going to be sold?
maybe, something like "CAN BUS switch panel module" where You can attach up to 12 switches/KEYS (latching, non-latching, multistate)?

Some issue that i have been experiencing on 1.161 FW. From time to time there is no Acceleration Enrichement in between the shifts. See the attached image from a log. You can see the shift point at 7K rpm and you can see the drop on the TPS. After that you can see the raise in the TPS, but you can see there is no acceleration enrichment applied, which leads to a lean spot. This is a bit annoying any suggestions are appreciated, but for me it looks like a bug.

I think im having the same problem with 1.161, i mean i didt do any logs but notice on my last race some bogging when release/apply on the throttle

[Jadzwin]

I check this

LC seems to have less fuel too with 1.161

Problem with Torque app.

The torque app displays the wide band AFR PID in whole numbers. Are there any plans to fix this? it's a bit useless in its current format.

Thanks!

Hi,

I d/l V1.162 and have some issues and recommendations.

DYNO
For dyno feature within EMU, why is the vehicle speed signal not used? If the vehicle speed is known than it wouldn't need the RPM/SPEED ratio. right? Something to be changed in the future?

LOG WINDOW (Graph 1/2/3)
When I load a new log and try to move the lower bar pointer to scroll over the log it keeps "hanging" on the end. Is this a bug or only my issue?

[Welshman]

i had the same with the log , if you click the red button ( pause and play ) it works ok

[RHD]

can we please increase the the frequency setting on the user PWM table?

we have an engine that needs 300-350Hz on the VVT and it is also very sensitive to very small DC changes. But we can only set 255 on the user pwm so this might be giving us a false settings when finding the steady state DC etc

[redmkiv]

Question for AFR Failsafe Map like Pressure/AFR or Lambda with warning/Triggerevent for a magentic Pressure Switch for drive only Wastegatepressure, if Lamdda/Pressure is out of Range, AEM Failsafe have this function i think it is a good Insurance for the Engine.

Hey guys,

it is possible to changes the x axis values for each table separately?

For example i want to use PWM#1 table to control the radiator fan and then i need at the x axis values between 70 and 110°C CLT. But when i now change it, it changed in every table that uses CLT.
So i need to change only the x axis of the PWM#1 table.
