i feel a meet at nick's in the offing.
Bye for Now!
I do too
Nick, which Saturdays do you have free between now and April?

thought i would round this thread up with the conclusion to my problem.
after meeting up with jason on the rescent birmingham meet, my troubles are over, and i am back up and flashing.
so i had some good news, i tracked down to my problem with my Flashing cable and ecuflash.
well it was the cable at fault, and not the main OP2.0 part but the little flash enable cable that was causing all my issues.
yes the sigle pin cable that is so simple it couldn't possibly fail.
Oh yes it can, i have the double ended 2.5mm male jack to male jack cable with the added female jack socket with the white connector on it that plugs into the flash port on the car. (same as yours Nick)
the connection between the male jack and the female skt was very intermitant connection, so when ever i tried to read my ecu it would try to connect and then fail.
so today i bit the bullet and cut the cable the leave a 150mm cable with one 2.5mm male jack on it and cut the female socket off the other cable and soldered them directly togather.
i did a resistance measurement to find which of the internal wires connected to the tip of the jack and in my cable it was the white one.
so it was just a case of soldering the white internal wire to the wire coming from the white connector wire and covering with heat shrink.
all tested and job is a done, reads the ecu evry time time now. Excellect.
A happy ending
Yes mate, much appreciated.
Noted, Dave! I haven't tried yet, but I guess I will be having similar issues.
not necessarily, but if you do start having an issue with connection to the ECU and it does not make any difference if the flash connector is plugged in or not then it is a prime suspect.
the other thing i would suggest, is when you are storing your flash cable when not in use, unplug the white coonctor off the male jack, i didn't do this and had it scrunched up in the glovebox so i think i must have applied sideways pressure to the joint for long periods and this must have bent the internal spring in the female jack socket so when i used it, it did not make a good contact.
unplugging it should prctect the intenal spring contact.
well it is a theory.
Jason do you have a modified ROM for MH7202 chip that gain additional 40 hp according to merlin's tutorial? I think I make mistake in modifying my ECU rom, didnt realize my mistake and know what to do. please attach us a copy okay?Originally Posted by foxdie
Well, I believe in sharing what I have been given, you can find all the ECU defs I've collected here;
http://dl.dropbox.com/u/36481366/ECU/galant-defs.zip
In there you'll find all the 7201, 7202 and 7203 defs for the VR-4 that have been put into the public domain, Kens 1.3 ROM, plus a couple of N/A V6 ones
I am having issues here too. Most frustrating! I am clicking the read from ECU button. I then get the select your ecu box. I select the 7202F option, second item down. I then get a warning/dialogue box telling me to connect the cable and turn the ignition on. I click okay and ecuflash starts doing it's thing. In the log box I get:
[12:53:48.328] J2534 API Version: 04.04
[12:53:48.328] J2534 DLL Version: 1.00.3210 Nov 22 2010 23:18:50
[12:53:48.328] Device Firmware Version: 1.11.3209
[12:53:48.328] Device Serial Number: TAIe5RVD
[12:53:53.218] sending init sequence 2
[12:53:55.231] J2534 error [ERR_TIMEOUT].
[12:53:55.746] J2534 error [ERR_TIMEOUT].
[12:53:55.746] interface close
All the items above marked [12:53:48.328] happen when I select the ECU type, then the following accurs at the end after I click OK.
Anyone got any ideas?
Working through this via WhatsApp now, will post up the results
if not already sorted by jason, bring you lappy and cable to the RR Day and we can sort it out then i am sure we will have plenty of time to do it.
Will do.
It's not sorted. I thought I had a bad connection on the ODB2 connector, because I could only intermittantly talk to the AYC ecu but could always talk to the EFI ecu when using evoscan.
However, I have now discovered that after trying to connect with ecuflash I can't talk to the ayc ecu in evoscan unless I talk to the efi ecu first. That rule seems to work reliably. I have no idea if that has a bearing on it or not?
I have tried lots of different ways of bodging the reflash connector too, to see if I had the same problem as you mentioned in post #43 above, but that doesn't seem to have had any effect at all.
On the plus side, I discovered that my car was missing due to leads/coil packs, not afr's, so at least it is running better. It is still slow though, as the afr's flatline at 10.0 on my wideband as soon as boost builds!
seems like a good chat point tomorrow.
Agreed
Closure for me - my reflash adapter was not connecting properly, similar to Daves post above, #43, but not the same wire. Having a second cable to compare it with meant diagnosis was much easier!
Many thanks to Jason for not only providing the comparison but also re-soldering my lead in to something that worked!
Glad we got you flashing
Ps. this is that boost solenoid I mentioned, yeah it's a lot of money but as a drop-in replacement without faffing around with wiring, it's not bad
does this mean you can start mapping in the north dave as its a long old drive to jasons (no offence jason)
i cant find anybody in the north of england who can remap vr4s and also pfl ecus like mine but on look out for a fl ecu i guess it will work in a pfl car
