Discussion and questions related to the course EFI Tuning Fundamentals
Made a basic ignition map in Excel based on other maps and information,would this be a good starting point for mapping the engine?
(Its for a 4age 1600cc na engine with other cams(264 duration 8.3 lift) headwork pistons etc )
note:its written in mmhg because thats what the engine uses.
Also the order might be other than what is normally used.
It's hard to tell anyone what sort of numbers should be in their ignition tables as each engine is different.
You should take a look at the road or dyno tuning to see how to approach creating a full ignition map. It should be done methodically from low load and rpm and built up from there.
If you don't run very high compression I would say it's a good starting point, the values from factory being higher than that.
(PS: it nice to see a fellow member of AEU86 here)
Would you happen to have a stock ignition map ? :)
I calculated the ignition points and pulled them back a bit for safety.
Yeah :D,under what name are you under aeu86?
I do have the 8bit raw data but I still need time (and €€) to make it an actual 3D table...
But I also have the factory ignition map from the Apexi Power FC and few others from tuned car on a dyno.
What I can tell you though is that the stock 4ag like to runs around 30° @ 100kpa and over 7000rpm, so what you posted should be a good starting point before the final adjustment on the dyno.
(and I'm Project D on AEU86 ;) )
Sorry for late response,tuning has been a bit on the background.
thanks for the info :)
Mine is a bit conservative just to be sure nothing goes wrong.
Aha ok :)
