problem reading marelli iaw 4af

[manuv]

Hi today I wanted to read with ktag a marelli iaw 4af sp to be able to read the eprom and map and then scodificare the ecu but doesn't go into the boot, according to you, what could I check I tried the ecu in question to connect it to the car and enter the diagnosis as the only fault code given is not
As 2 what to exclude the ktag I tried aleggerne another similar always marelli iaw 4af pw and this is the read immediately now I wonder if it is a problem of ktag or ecu

I think that is a problem of the control unit, the 4af and one of those ecu that you read and wrote easily....

I can tell you that if I I connect the ecu to read to drive I encounter the code as a right that is given that is a controller used that I wanted to read for scodificarla if I read with kess leaving it connected to the car is read the map regularly now I was wondering if I dissaldo eprom 95160 from ecu and original and the balance on the receiver to mount the car would start, or I have other blocks that start on the map, thanks if this is not possible I will try another ecu thanks

everything you need is in the e2prom, then remove and swap the e2prom, make sure that the sw on the flash is the same otherwise write the original.

the sw of the flash I should be able to read to see if it is the same with what I read the flash

here you say that you read the map then you have the file of the flash in hand, or I've misunderstood me.

if a the read the problem is not the ktag , and then, as it says in ugoboss if you have done your reading you also have the right file
