hi

i have read/wrote/cloned many sid211 ecu’s no problem using the old hexprog, since buying the new hexprog 2 i have cloned one and it worked fine although i cant remember if it was a sid 211 or sid209 to be honest,

i have just tried to read another sid211 ecu using the nex hexprog 2, but it wouldn’t communicate, so i tried a different power supply, that didn’t help, so i re checked my wiring and it was correct, i also then turned everything off and then back on but this didn’t help?

i then tried with another known working sid211 ecu and this was the same?

im using 14.5 when trying by the way,

can anyone offer any advice or anything else i could try?

cheers

chris

Please make sure all wires are connected well on the ECU and Hexprog/HExprog II tool. This is possibly a wiring error that caused no communication. If same, please get in touch with our support team to check.
