VATS deletion E40.....stuck in the mud!

[ssvolvo]

Yeah it's me again trying to get my moneys worth on the forums.

Should be simple but it's not. This time I am trying to delete VATS on a GTO E40 for use in my Vulvo swap. The engine is up and running on another E40 with VATS delete just as it shows in the software and forum searches. Engine will not crank after Vats delete. This is the code: P1629 theft deterent signal not learned. This implies to me that I have not properly deleted VATS. Have full reflashed with different settings many times.



Might one of you with more knowledge than I offer to look at my tune for VATS delete?





No rush, there's a beer in the fridge!

Thank-you, John with the Volvo that doesn't crank.

Have you tried flashing in the Voy OS or are you trying to get this to work with the GTO OS? Its definitely the GTO OS from the VIN, you've full flashed the OS after making the VATS patch correct?

Looking through the DTC Type stuff, have you tried disabling first P1629, P1631, P1648, P1677, P1678, P1679? And maybe look at P0513 & P0633 too.

I've been trying to keep it simple so I did not change any of those DTC types. Only full flashed the GTO OS into the GTO E40, with no other changes but VATS delete just to set a starting point. EFILIVE won't full flash the Envoy OS into the GTO E40. Actually posted about that a while back and the hire ups tell me that the OS are completely different and I'd lose the DOD.
My thought was to just change ALL (throttle body, APP sensor) over to GTO stuff because of my recently aquired bad taste of DOD operation as the car shakes worse than a preacher in a house of ill repute. Have searched Vats delete E40 in forums and only a couple of posts come up.


Spent 10 full hours yesterday working on BEN logs and learning the software. I've had this over a year, taken the EFILIVE training (which was well worth it), and lost most all of the hair that was still left on my head. I've installed and tuned Holley, Accel fuel injection systems and tuned MANY carbureted vehicles, lawn mowers, saws.....yadayadayada but this program is kicking my A$$. Ounce I get it down the payback should be huge. We just purchased an 08 HD 2500 6 liter. AVERAGE fuel consumption on paper has been LESS than 10 miles per gallon....Thanks GM!


Would you suggest I delete those codes and try again?


Thanks,John

Is the tune for a manual trans or Auto?
If it is for a manual it is probably looking for the clutch switch before it will crank.

Cheers,

Thanks for the reply, The tune is from an automatic. I also have the T42 with the same Vin#. The clutch switch is checked also....file is in first post.
I'd love to be able to use this ECM. I'm ready for the next step!??? Thanks, John

Please check C1 #51 circuit 275 green/blue wire needs 12 volts with the clutch in.

One can override this setting in G1213.

Hope this helps, I still LOVE my Volvo LS2 conversion, it burns rubber like nothing I ever owned. Best pass 12.1 seconds 113mph. 25 MPG.

Yup - C1 #51 circuit 275 green/blue wire needs 12 volts with the clutch in

Then - C1 #13 pulls ground to energize starter relay?

Does C1 #52 get 12 volts from the ignition switch in Start position?

Looking forward to wasting some rubber. Thanks.

[ssvolvo]

Yes, purple on GM is usually cranking voltage. Pink is 12 volts with key on. Also if you want the cruise to work you will need a GTO cruise control interface module that converts cruise switch to CAN language that the ECM can read.

Also, as you mentioned the pin C3 #22 needs to be grounded for start. Where is this signal coming from on a GTO with a manual transmission? There is not TCM or Park/Neutral switch.
