Hi All,

OK answers..

1) Supercomp: There is no TPS load input it is purely based on pressure. if you are using TPS as the load sensor then either hookup a gauge to see what it is doing and then use that as input for the calculator or simply put in a 'guesstimate' and see how it goes.

2) barojas: The shape of the fuel map will most likely not be perfectly linear in a properly tuned car. remember the calculator is designed to create a base fuel map to get yoiu started and running along with being very driveable. But the map will not be optimised. you will be surprised at how well it does do the fuel curve even when assuming a linear relationship through the load and rpm ranges.

Good to see people still interested in the Calculator..its been a while since i logged on to see how its been going.. :)

cheers

The way i use your calculator, and im sure most people already do this, right?, is by modifying the load vs. rpm to get a more precise map with a varying fuel load/boost condition, that way the map does take on a more accurate behaviour under the different load/rpm ranges, since the fuel injection time for 10in/Hg at 2000 rpms is not the same as 10psi at 5000, you get the idea. Thumbs up to you Engineer.

Hi Claudio,

Thanks for the thumbs up!! :)

Greatly appreciated!

One question I have for you is how many cars have you "tuned" with the calculator ? Were the results similar across all of them ? I am really interested to see how everyone is using it !
be cool

Cheers

I am going to bump this. This is a VERY cool tool. I am going to post it on the IS300 forums. This is going to be very useful for first time tuners. Claudio, what do you mean you do load vs rpm? When you change the RPM value it doesnt affect anything.

Nice tool!!!

Would have been even better if you would use SI-Units 8)

It will probably come back up. Seems to be something with the forum

Tried to attatch the file to a post but got
"Could not upload attachment to ./files/1664_0c475fa52f81d52759ab9c517ff6b0d9"

I found this on fordlaser.com just the other day
but i get the same "Could not upload attachment to ./files/18408_ab028fcced15eeb71fcfc3c3aefcae06." message
you could sign up there and find it, also posted by engineer

so i put it here for you

Hi All,

I have not been on these forums for ages :) (Coz my Haltech system just works !!)

But I notice dthat recently peopel have been hitting this thread and have not been able to get access to the calculator.

For some reasons the forum is not allowing file attachments :)

It can be found on the url below
http://www.fordlaser.com/viewtopic.php?highlight=calculator+injection&t=60797


I am so glad that people are using it and getting the best use from it. I look forward to hearing some more success stories with it and if people have a consensus on new functionality ( and i have the time!!) I will create a version 2!!

be cool and Enjoy !

Cheers

Yes Sequential is the mode it simulates.
Aslo the RPM value does not change anything actually as the units cancel out in the equations. But it is meant to be each RPM step value in the map :)
What do you mean by does it "apply for all engine configurations?" ? It will do 4, 6 and 8 cyl only at this point as I have not catered for other engines like rotaries.
I hope that helps. let me know how you go :)

Cheers
Engineer

I wanna go back to this question for you, i asked if the fuel mode it calculated at was sequential, you said yes, but, if you think about it, an E6X cant do sequential on a 6 or 8 cylinder, only 4. And from the results i get on this, the values look more like multipoint values than sequential. Could you clarify this a little bit?
