My post seems to have disappeared, I'll try again.
I purchased a tcm2650 from the states Last year to put a 4BD1T & 6L80 (ex 09 VE V8 Commodore) into a 105 series Landcruiser. It's been up and running for about 5 months now. I have TUTD, normal, PatternA and 5th lockout in all modes via shifter to d5.
I did a bit of stuffing around with inputs & outputs on the 2650 but only had 6 days to get it up & running inc tuning the 6L80.
I'm sure you have worked out that you have to download the software for the pcs TCM2800 to be able to change anything in the 2650. Most of the settings & adjustments shown once you get in there should not be adjusted or altered as you cant use them to control the A6, and if you do change stuff it probably wont communicate with the A6 or do really weird stuff. The 2650 has less functions, the 2800 software shows everything a 2800 has, so be careful.
There is a monitor mode in the pcs software but I found it doesnt work, but you can go online with the 2650 and do live changes if "firmware version & serial" is selected in the monitor window. Make sure you save the parameter you are working on before closing it in online mode. You can then use vcmscanner connected to the A6 to see changes you are making in the 2650 with the engine off ie. tps, TQ, pattern A select.
You must use HPTuners or equiv to do all the calibration stuff in the 6L, shift schedules, pressures, pattern selects, TUTD etc
I'm running windoze10 and all seems well.
The TUTD is hardwired. I have a up/down switch on the stick and a cobbled together resistor network. It works fine. I have TUTD in D6 and shift to D5 to cancel.
The tps signal the 2650 is looking for is analogue 0 - 5v, .6 idle 4.9 wot, which you can change in the 2650. As far as I know you can use a MAP input but no both TPS & MAP. I haven't tried this but you would have to scale the TPS & TQ out tables based on MAP only to suit you application. The 2650 produces a TPS% out & a TQ Nm out to the A6 based solely on Analogue TPS position.
The 2650 only has 2 analogue input available, there are limitations with other inputs and outputs as well because it wasn't designed to control the tranny directly. The pcs tcm2800 has all the functions & ins & outs shown in the software, but no native built in software to talk to a mechatronic tranny. Check the block diagram of the tcm 2800 vs tcm2600.
You only need a TPS and RPM signal into the 2650 to make the 6L work. I think it will even work without RPM.
I do not have GMLAN or can signals to play with to test that side of it out. If you are running a GM ecm with that data on the CAN, could you just connect it to the can for the A6 and read all data with VCM? My understanding from the conversation I had with the vendor in the states is that CAN functions are very limited on the 2650.
You will definitely have problems if you try and use any of the outputs for anything other than what they already are, except for pwmout 9 as it is the diagnostic light out. pwmout2 is the TQ output table via CAN to A6, TQ out =tps%x10 ( the output pin on the 2650 will still output what ever is in the table as well as - voltage), pwmout3 is the TPS% output table via CAN to A6, pwmout6 I think is a scalar for tps & TQ tables maybe?, pwmout8 I have not played with as it faulted the TQ converter lockup when altered by 1 unit at 1 point.
The other pwm tables if altered will result in no communication to A6. pmwout 5 & 6 have no functional output via the external pins, pwmout 1 & 7 are the reverse & NSS outputs, make sure they show "pwm vs current gear" if they are not working right. The only spare is pwmout 9 which I have connected to my old Check engine light as a diagnostic indicator.
All outputs are earth switched and yes reverse & NSS require relays.
My suggestion is to revert back to the cal that was in the 2650 when you received it. If TPS & rpm are connected properly you should see values change in vcm scanner. when I altered the outputs to other things I only had rpm showing.
Note A6 modes are changed at different tps% setpoints. 2650 as it comes has 92.9% max sent to A6. There are a couple of wot modes activated by changing this to a higher number. At 92.9 WOT mode in the A6 is never seen, when I went above that it tended to hang in those modes so didn't play with them any more.
I have a mechanical injection turbo diesel with 630Nm TQ@1600, 145Kw@ 2400, 3000 rpm redline, 570Nm TQ from 1300 to 2300. I obviously have no torque management on the engine, but left it all active in the A6. I have 15000Km on it, so far so good.
I'm using a switch to select calB via Digitalinput2. This gives me PatternA selection in the 6L, not in the 2650. I had to change pattn1 to pattn2 to get the A6 to see it. When I get some more time I'll play with the other pattern settings as pattn2 seems to toggle the input from the 2650, so two pushes of the button to get back into PatternA. The 2650 sees the button every time,tested with trusty diagnostic output pwm9.
I'm also using 4WDLo input to correct my speedo in lowrange using digitalinput3. It would also work if you were swapping Tyre sizes regularly to keep the speedo accurate. It has no effect on the transmission.
I'll see if I can attach a tcm2800 start guide and block diagram.
No dought more questions than answers.
