Re: Gearshift Maps
sweet
maybe it's the tcu from the us obd2 svx. I just got one. I'm doing a lot of soldering today but I'll try to pull the firmware off all the US tcu's you don't already have the firmware for and email them to you today. I'll take a couple pictures of the 96 tcu. Same plugs, same box.

Re: Gearshift Maps
you got all the obdII ecu parameters and com commands from the 96 select monitor bin now right?

Re: Gearshift Maps
i saw a picture of a select monitor II on your website; do you have one/can you get your hands on it again to look inside? I happen to own a master cartridge for all 01 through 04 model subarus.

Re: Gearshift Maps
It's in the 1992 cartridge.

No. I just pulled that picture off the net. I've been negotiating to borrow one off somebody. I was planning to eavesdrop every single cartridge and post the parameters on my site. A lot of people are guessing addresses for datalogging and getting them wrong.

Re: Gearshift Maps
It would be a lot faster to pull them off the master cartridge. I believe the 2001-2004 is the least supported range of obdII Subarus so that should fill in a big gap of knowledge. I'll pull and read the ROM off it and send you the bin.

Re: Gearshift Maps
When I built my first cable, I did a scan of all the possible SSM command bytes and found 78 (ecu), 45 (tcu) and 89 (a/c). The cruise and 4ws units did not respond.
In the select monitor code, there is an extra step when talking to the cruise control unit: example: Code:
a26d 96 40 ldaa (0x0040) ; Unit Flags: x,y,z,4ws,crs,a/c,tcu,ecu a26f 85 08 bita 0x08 ; a271 27 06 beq [0xA279] a273 d6 11 ldab (0x0011) ; TxRx CSR1 a275 ca 06 orab 0x06 ; Transmit_Enable + Transmit_Interrupt_Enable a277 d7 11 stab (0x0011) ; TxRx CSR1

Re: Gearshift Maps
It looks like the extra wire from the cruise control control unit is the same as the extra wire from the ecu. I just traced it and it also goes straight to pin 35 of the cartridge which I discovered yesterday dead ends where there is no resistor installed to connect it to vcc in the cartridge.
that does mean the two are connected when the select monitor is plugged in so the ecu could be providing something to the cruise control unit

Re: Gearshift Maps
i just probed the select monitor connector on my car and pin 8 wasn't showing any continuity to the other pins. pin 4 looked to be pulled low through a 4k resistor showing 4k continuity between ground and 12v and showing 12v between it and 12v.

Re: Gearshift Maps
when you get a chance if you could check the values of r213 and r315 and see if there is a r408 and 409 in the uk and jdm tcu I'd appreciate it.

Re: Gearshift Maps
thanks, what's the part number on your board? how about the lable on the ROM that's in it?

Re: Gearshift Maps
I figured out why I couldn't find my 94 bin before. The 705404 firmware is the firmware out of the e23aa12p ROM from a 93/94/95 TCU (I just read an e23aa12p ROM and that's what came out of it and I compared it to your 705404 and they are in fact identical). We should have nomake check the ROM id on his TCU. I'm guessing he has a TCU with the e23aa12p ROM. The firmware you don't have is from the e23aa11p ROM and the obdII firmware from the mq labled tcu with the e34ua1dL ROM.
