Bugs and Feature reqests

On a sidenote, maybe we should stop suggesting new features, as some people will always chim in and say it's not needed, it's already possible etc. Maybe the EMU is perfect so the feedback is not needed, no room for improvement.

Of course not Nick
Its just that some features are really hard to do thanks to how the main platform code is written from the start. The PRO will have a brand new platform that is 100 times more flexible for such functions

before some time i report my problem but i don`t recieve solution. when engine start afr start to show afer 1 min.! if i use "enable when no rpm" the problem is same <- this option has never worked for me. from the begining my afr shows after engine is started.. but for 10-20 times. when i update ECU start to work again.. but for same time.. for last 5 update AFR start to work after 1 min. and every time when start engine after 1 min AFR start to show.. with this problem when my engine is cold i don`t know afr is rich or lean..
i use EMU from soft ver. 1.3x now i use last soft.

this is my log with little test

That's not a problem, it just that the sensor takes some seconds to warm up

ok but i don`t have "lambda when no rpm" and i try to make good settings when try to start cold engine and i don`t know rich or lean is it. And why from the begining (and when i update for first time my EMU) lambda start to work immediately when engine is on( first 2-3 days)

Can you please add a speed dependent lockout for the coolant and a/c fan?

Use parameter output.

Use parameter output.

Thanks, i keep forgeting about the parametric outputs. I already did some settings to test tomorrow.

But it would still be better to have these settings there, esp. for the a/c fan, since many people will use it.

I am trying to improve engine start on my Honda S2000 as it takes too long, and i am experimenting with the prime pulse times. I am watching the data logging, and i don't see any injector pulsewidth present before engine sync, i also don't see any injector action during the synchronising. I only see the injectors working when the status goes to synchronised. Is this a datalogging error or a malfunction?

Its only going to send fuel and spark when the ecu knows where the engine is in its cycle.

This goes to the cranking fuel only. Prime fuel is being delivered when first revolution is detected, before engine sync. I already got my question answered from the ecumaster team, the prime pulse is present but doesn't show in the data logging

Scramble boost similar to ProEFI would be great!

From popular demand, ProEFI has implemented a Scramble Boost feature to work in conjunction with its iBoost control system. For those not familiar, Scramble Boost is a feature that allows the user to temporarily increase their boost pressure setpoint for a pre-determined amount of time.

With the ProEFI iBoost system, there are 5 pre-deternined boost settings from wastegate pressure to the highest boost level. If used in conjunction with the ProEFI Flex Fuel sensor, this highest boost level is limited by the ethanol content seen in the fuel tank. By adding a momentary switch, the ProEFI Scramble Boost feature will allow 5psi (or whatever the desired level is) above your current boost setting. For example, if you're on iBoost Stage 1 (which is wastegate pressure) and your spring is 14psi, you will now have 19psi for a pre-determined amount of time (in seconds) before returning to the regular boost level. This feature is highly sought after among drag racers and road racers alike when that extra power is needed and there isn't enough time to change boost settings.

This feature is also protected by the ethanol-content feedback meaning if you don't have enough ethanol percent present, the ProEFI will only allow you the safest amount of boost to maximize performance yet not exceed the limitations of pump gas (or your pump gas and ethanol mixture).

You already have this feature via the timers option.

Didn't know that, thanks!

a nice feature would be able to select cells
and then click richt mouse and choose enter value.... like most of the ecu's have and DET3 has..... maybe i misted something.
but its not there on emu

maybe open up tunerstudio Ms one time and have a look, much more plausibility's. to enter number,
VE table generator maybe
Life auto-tune function instead of log and auto tune function.


other then those, emu is a great ecu, and black is fantastic.

In car it is very complicated to use the mouse. It is better to use only keybord.

So if you want to enter value to cells just select the cells (SHIFT + arrows like in excel) and just type the numers or press enter.
If you want to make any math operation just write it. Eg 2* will multiply all cells values by 2. You can scale it by percent (eg. 90%) and so on.
It is more comfortable way to work with tables than press mouse button, select enter value, enter value, press enter.
With EMU table idea it is much much faster.
And od not forget about undo option. You can undo all operation you made by just pressing CTRL+Z

i was thinking we could add a function to the shift light. a simple line of code to allow users to set up a flashing or strobe setting that increases in frequency when getting closer to a set redline until it is finally a solid light.

Is there any chance we can add a sensor input for Nitrous Bottle Pressure & Brake Pressure? I want to use the EMU to monitor Nitrous Pressure and also to control the bottle heater on/off.

I wanted to use A/C Pressure for the Nitrous Bottle Pressure but upon looking it only goes up to 5000KPa (About 750 PSI). Nitrous sensor would need to scale up to about 1300-1500PSI (8000 - 10000KPa).

An input for Brake pressure would similarly need to read up to about 2200 - 2500PSI.

I have 0 - 5v rationmetric sensors that read up to 2500PSI to use for both of these applications but the only way I think I can make this work for now is to use a parametric output based on raw MV values.

Thanks guys!

Can you add one more parameter in idle parameters, "afterstart rpm increase above coolant"? When afterstart and engine is below operating temp, the idle is high anyway.
And, in the fueling/fuel cut parameters, can you also add a parameter, "increase fuel cut rpm when coolant below"? So the increase rpm point will be disconnected from the afterstart enrichment engine cycles.

i aggree, but for setting up the table its nice to select some cell's and then click enter value like in DET3.
but maybe its just because i am use to it. will see.
