VAG MARELLI IAW 4LV

[panos1975]

I am looking around for a def file or a map pack with some basic maps for this ecu.I am also interested if someone has any info(documentation, structure data, etc) generally for marelli ecu's (petrol).Any help is really valuable.If someone could share something relative with this ecu i 'd really appreciate it.Thanks in progress.

ECM titanium have drivers for marelli IAW 4LV. you will find ecm posted in this forum. good luck

Imo thanks for your interest.Ecm has only 2 ignition maps,rpm limiters and a map that describes it as injection part throttle(if anyone knows what exactly is for and how it works please explain).I am looking after ecm for a map pack or a def file or a documentation for this ecu or something which could help me to make a decent tune file.If anyone knows something further please help.

yes, but as i know for a petrol aspirated motor these maps will be enogh to tune

Do you know what exactly is the map that ecm describes it as injection part throttle?Is something for fuel or for the trottle blade(how fast you want to react).also do you know what are the units of axis or the factors for them?thanks for your interest.

hehee, mate this is a good question! i`m intrested too about this... i`m a very begginer in this problems. i have buyed a tuned file for a 1.4 petrol engine with marelli iaw-4tv ecu and as i saw only these maps are modified , injection, spark advance and rpm limiter... if i will found something about axis descriptions i will say you.

made with ecm.did you flash it?did you saw any power gain? the map is refered as injection from ecm i think is for throttle response.
