target AFR table Problems!

#1 ◈ 2013-05-20

I am using the latest turboedit and ecucontrol.
When using the "stock" target AFR table the autotune function calculates the new values accordingly to the afr table and it gives values like -5%, 10%, -2%, etc. The "stock" AFR table is set like this: 15,15,15,14,14,14,13,13,12
When I try to smooth the afr table to let's say: 15,14.7,14.5,14.2,14,13.7,13.3,12.5,12 THEN the autotune function calculates the new values all wrong. It calculates values like 840%, -456%, ...
The decimal point is the problem, because without using it, the values are correct.

Where could be the problem? - Internal calculation or some sort of settings?

Re: target AFR table Problems!

hmmm...i've never had a problem with that before.

i have some xx.5 values and they calculate okay.

looping values through a modem, i tried putting some xx.2 and xx.7 values in for the targets and everything calculated "correctly"...i will hopefully get time to try it in the car this week.

are you changing the target values while driving, or did you load your table first?

Can you change the target values while drving? -I can't. I am using my own target AFR table.
It seems that it reads 125 instad of 12.5?

And also with the original table it doesn't work right when it goes to 0.5PSI, where the original table is set to 12.5 :roll:

Specs:
turboedit 3.1.7
EcuControl 6.1.15
WinXP SP2

Maybe do I have to set something in options?

yes should be able to change the values within ecucontrol (cant remember if it skips blank cells or not).

post up a copy of your spreadsheet (csv)...maybe its an issue with the way its saved? i will try yours and see what the issue is...

I now noticed that you can change the values. At first I didn't realize it because I couldn't select the value :idea: :oops:

I attached my copy. I don't know if it something wrong about the way it is saved, but it loads like it should.

Thanks for your help!

Re: target AFR table Problems!

ok, i checked the coding last night...and i didnt have any of those problems. i tried up to 4 decimal places and it still worked correctly. i did however find an issue that "could" cause a problem...so let me tidy up and add a few other small things that were on my list and i will post an update soon.

i've had a few of those issues where things work correctly on 50 computers, but the 51st causes an error... :roll:

Re: target AFR table Problems!

If anyone wants to experiment with this target AFR.I`ve written the correct vacuum and boost values for the NG63 rom and correct RPMS so you don`t get the old NG roms values, and also smoothed out the target AFRs.
