Starting problem commodore vu ute

Hey Wade,


Serial wideband: do you have this connected to V2 (using null modem adapter or wiring modified to do so)...?

Is your V2 able to read the AFR, Lambda and EQR from the wideband...?

Log these pids (in addition to the other AutoVE pids):
- GM.EQIVRATIO
- EXT.WO2LAM1

could also log these:
- EXT.WO2EQR1
- EXT.WO2AFR1 (depends on stoich AFR assumed by wideband)
- EXT.WO2ST1

make sure the pid channel count (shown at bottom of PIDs tab and Data tab) is 24 or less...

( EXT.xxx pids occupy zero pid channels )

if you have pid channels left (before hitting 24), you may want to log GM.AFR, but I think it's better to avoid it and use GM.EQIVRATIO instead;

if you don't already have one, you will need a BEN pid defined as "{GM.EQIVRATIO}*{EXT.WO2LAM1}"... this is already defined in the calc_pids.txt file of the Calc.VET thread (see post #1).

So was he saying that the plugs foul easily...?

No more that since they had about 80000kms on them and looked like a lot of carbon on them to give that a try.

I'm using the innovate lc-1 hooked up using a null modem adapter.
I can read the afr on the v2 but couldn't get it to map correctly. Looks like i had the wrong pids selected compared to the old v1 logging in analog.

You need these pids:
- EXT.WO2LAM1
- EXT.WO2EQR1
- EXT.WO2AFR1 (depends on stoich AFR assumed by wideband)
- EXT.WO2ST1
- GM.EQIVRATIO

I installed roadrunner with my tune and 1250003 operating system and am using V2 usb in 2001 vet with procharger

RR programed just fine but car won't start, do i use 7.5 or 8 to tune car and shut off vats? don't see on tune where to remove vats
could you help me? i am not real savi with computers but i have laptop dedicated to EFI Live for my car
Thanks Greg

Greg,

Use V7.5 tunetool for reading, editing, flashing (V8 tunetool is not ready yet).

In the V7.5 tunetool (note: V7.5 is aka V7 for ease of typing):
- G1204 if you want to disable VATS (goto System Segment, open folder VATS);
- do Flash->PCM Security->VAT Relink if you want to relink between BCM and PCM (you would have to set the VIN first);

To set the VIN in the PCM, you can so it either of 2 ways:
- tunetool: do Flash->PCM Security->VINN/BCC;
- scantool: do Bidirectional->Change VIN.

Greg,

If you flashed your ECM using V8 (should have gotten a warning regarding ETC), then you should have first saved the tune file using V7 tunetool.

Use V7 (i.e. V7.5) tunetool to do any PCM related flash stuff (reading, saving to file, editing, flashing)

(of course with RR you don't flash, you send it to the RR user the USB connection)

It seems to me you are using V7 tunetool for all this (since only it has the RR interface).
