hi Danial,

1) Made changes to basic ignition map. seems to affect entire RPM range.

2) just realised my rev was still limited. Increase rev limit worked on my original bin tuned using the MS430066 XDF. it did not work on my current bin.

thanks

I know that there are 2 main maps related to fuel.
1 of is basic injection, which is in your screenshot. The other one is Alpha/N map.
But i don't know which one ideal to tune. In which conditions tune which of them etc.

I wonder this, how much air/fuel ratio changes depends on %1 or %5 increase of these maps.

Very small because injectors are small. Try 20-25 to see the change.

Don't know, try one by one. That is the best and fastest way. I hate oem ecu's, and always use standalone, but what I said is the same for oem and sa. Small injectors=big percentage for a change to see.

Stock basic ignition map



Tuned basic ignition map



Difference (stock vs tuned)






So, do they still too lean to increased ignition advance? (+1.5 degrees)

Hard for me to say, I use proper wb lambda to check the afr, not just tickering with the maps. I can only offer advice how to do it properly.

That's the best way, i know.
Can you say that how much afr changes every 1 degrees of ignition advance or something like that?

The screenshot says you are tweaking basic injection, rather then basic ignition.

Do you want to tweak a single supporting point one by one or do you want to tweak a whole row/column?

In this screenshot i selected the whole map and filled the supporting points with value 1.5 and its working like it should.

Make shure you save the bin file, maybe with a different name or even in a different folder. There shouldnīt be any issue with this. Your car is manual i guess?

I did, but i donīt understand your approach. You canīt simply raise fuel to compensate for earlier ignition.

Doing it the correct way would mean to purchase a knock detection tool and tweak the ignition.

Yep, or visit professional dyno, NOT dynojet or similar trash.

Hi Danial,

thanks for the reply.
yup, I meant the basic injection map.
I want to tweak a column only. had the car on a dyno, adjusted rows between 4100 to 5500rpm. But ended up increasing fuel to the entire rpm range.

Simply click on the column (in the screenshot i clicked on "550" to select all the support points within that column) and manually tweak it.



If its not working for you, try to download the latest TunerPro software and reinstall the old.

Are they still connected and give false information or are they disconnected and you need to get rid off the codes?

It is for a tracktool, will swap a 200 cell catalyst and need to get rid off the o2's and of the codes.
Beside of the codes I'm not sure if just disabling the codes is enough or maybe other parameters must be changed for preventing an impact on fuel mixture.

Unplug them and use INPA to reset Adaptations (F8)

Or flash a new EU2 software onto the ecu, which actually changes C_CONF_MIL to 0. So its actually a single byte switch.

for some reason I don't want to flash the eu2 sw
It is enough to set c_conf_mil to 0, unplug them and reset adpations ?
I don't need to delete dtc's ?
