Title: Bensh flashing ME7.5 Post by: papasound on April 26, 2013, 06:47:28 AM Hi i have done everything as shown here
http://www.nefariousmotorsports.com/wiki/index.php/ECU_Bench_Flashing except i put 1k ohm resistor on pin 24, and 5k ohm resistor for touching pin 24 on F800BB, I just cant find out where is the ignition switch, which pin should be fed with what?

Title: Re: Bensh flashing ME7.5 Post by: papasound on April 26, 2013, 10:06:23 AM so presumably it should be connected to 12v+ all the time, or after power on and some time after?
Title: Re: Bensh flashing ME7.5 Post by: cyril279 on April 26, 2013, 10:38:49 AM many leave it powered all the time along with 62 & 21, I had to install a switch on pin 3 to get mine (me7.1) into bootmode.
Title: Re: Bensh flashing ME7.5 Post by: papasound on April 27, 2013, 01:16:24 PM Thanks for your replies, and i got another question. I unsoldered 5040 and put bin with immo off, do i still need to power pin 21 with 12v+?
Title: Re: Bensh flashing ME7.5 Post by: papasound on April 27, 2013, 07:08:21 PM After so many unsuccessful tries i finally got it into boot mode:
Put 2k ohm resistor for pin 21 power on, ground pin 24 on chip, ignition on, after 10 seconds release ground from chip, try to communicate, fail, ignition off, 10-20 seconds wait, ground pin 24 on chip, ignition on, after 10 seconds release ground from chip, try to communicate, success, power off. I have Infinion cpu and only that dance saved my day. Boot mode flashing took about half minute using eobd2Flash cable with FT232R chip and fresh drivers from http://www.fgtechnology.eu/ |
