I really don't think that u have to change to 2000rpm...

I would stick to 1000rpm...
the calculator will give u the minimal and maximum limit for each Inc spec and target AFR...
it works on all RPM for me..

Hey!

This is what I don't grasp 100%. The maps in Halwin are mostly rpm related.
I would think injection time would change from rpm to rpm?
As far as I can see on this graph it calculates injection time vs load?
The e11v2 needs to be mapped injection time on load on rpm?
Or am I missing something here?

Or will the increased rpms (increased number of injections) increase the amount of fuel the engine get's hence the injection time stays more or less the same on all rpms on each load level. And that case load is the only varying factor? If this is the case, then I understand it. Sorry for me beeing ignorant ;)

I'd like to use his calculator to calculate my base map, since there is none for my Maserati.
I just need to understand how to convert the graph I see into a base map.

Thanks!

Cheers, Jarle

Hi Jarle,

The RPM value cancels out in the equations. Use the same injection time across all the RPM points and it will work just fine. Essentially the load will determine the injection time value in the calculator. Just rememeber it is only a base map calculator as the tuner will tweak the injection timing for each RPM point for you :)

Hi Bavbim,

I am very pleased to hear that it worked well for you. Can you please provide details of your engine configuration for everyone to see and also maybe provide a comparison of the final tuned map to the base calculator map so we can all see the comparison. Also any comments on how smooth or rough, rich or lean, the engine was running on the calculated map will be great so everyone can learn fromt he benefits of your experiences.

As I am the only person who has really used it to date, I am really happy that it has worked out for others as well.

Something for the Haltech website I think if it works for everyone.. :)

Cheers
Engineer

sure... no problems...

4G92 1.8L (stroked) SOHC non MVC Turbo Intercooled engine...
I just set the AFR to 60deg on the calculator and targeted AFR to 12.5 since I am running in Turbo.
Injcetors are 300cc/min
Using Haltech E6X
Internal part of engine all have been upgraded.

I got the base Injc map from the calculator...
great things....
after I got for the 1000rpm...
it all very easy for the rest of the RPM wideband..
anything else I need to share...?
please ask me..


For Jarle,
it might be needed for u to bring ur car to a tuner...
since u don't quite get to set the fuel map...

once again thanx engineer...

Hi Bavbim,

Thats great thank you :) Can you also please detail how well the car idled and drove at all the different speeds with the calculated map only. Was it smooth..did it stutter, did it start easily on the first go etc etc.

Any information would be great :)


Cheers

very smooth indeed...
AFR is between 12.5-12.7 I guess its normal.

runs great on every different road (rough,smooth,decent,hill climb,etc)
Very great on full throttle..
Idle at 850-900rpm.
for note:
I don't enable zero thrl and full thrl map.
I do use IAC and the setup enable....
use sequential injc.
and use air and coolant temp corrections map for cold starting.

Yes it starts on the first run...or crank...
no problems at all..
the calculator just give everything I need which is:
The minimal and maximum amount of fuel that my injc should do.
the rest of it just like regular tuning.

I haven't dyno it yet..
maybe next week...
since there are lots of work on customers car to be done before the end of the week.

anything else?

* The RPM value cancels out in the equations. Use the same injection time across all the RPM points and it will work just fine.

This is basically what I wanted to know. I now know how to transfer this to the fuel map.

* Essentially the load will determine the injection time value in the calculator. Just rememeber it is only a base map calculator as the tuner will tweak the injection timing for each RPM point for you :)

I sure see that. When I first saw the calculator, I thought the meaning was that you should run the calculator on different rpms to get a variable map.
I see your point now...

Thanks!

I know how to set the fuel map.. I was expecting the injection times to change on different rpms.
This is what I didn't quite grasp with the calculator.. Now this is cleared up, I will use it to make a base map.

Cheers, Jarle

Hi Jarle,

Thats great news dude. I know that it seems a bit odd at first about the RPM points all needing the same injection time( I was myself surprised until the eqauations all fell out. As everythinbg I knew told me that the change in RPM will change the injection time) but the RPM seems not to make much of a difference to the useability of the calculator.

I am really looking forward to your feedback to see how the calculator goes in making your base map. Give us a rundown like bavbim did so we can all see how it goes on different configurations.

I am very interested in your feedback and your success. I really hope it works as well for you as it did for bavbim.

Good Luck!! :)

keep us posted !!

Hi Bavbim,

That was perfect feedback. Very glad to hear it work out well. I hope other people get a similar result from it :)

Hello,

how can i use this file if i use a tps sensor instead of the map sensor.

any conversion?

best regards,

Is a proper (best performance) map supposed to be linear?
What about the air temp? This changes slightly during warmup and or driving, especially traveling or going up a hill...
