Thanks for everyones help. classic swede was right . I rebuilt the vapouriser with new diaphragm and seals all through. The diaphragms looked ok but some of the seats looked worse for wear. Nearly back to normal! Before the rebuild the laptop wouldn't connect to the ecu all software seems ok and usb ...

Hi, tried your suggestion and the system doesn't function without it connected ?? I cant alter the cut in time or temp can anyone explain? cut in temp is 30deg c with a 40 sec timing. Tried it for the first time from cold this morning .The gas cut in too soon and the engine stalled ? Seems to be ...

Hi , Thanks for everyones input . Just run through the auto calibration (and ignored the flashing OBD) function --its re-calibrated and seems to be running o.k now . Are the Blue injectors classed as `fast' and should the ignition sensor value be set to standard or weak? Just to confirm. Many thanks ...

Hi, Just had a quick look at the software last night and there isnt an option of `none' to disable the OBD. I'll run the auto cal again and see if it still hangs up on the 2 to 2500rpm section ? Thanks and best regards Richard

Hi Simon, Thanks very much for your response. I will try the self cal prog again -I remember not being able to get passed the 2to21/2k rpm test for some reason . but will try setting the OBD option to `none' and try again. My Range Rover is the later P38 4.6 Thor Bosch system. Regards Richard

Hi, I have tried the auto cal but it does seem to rely on the connection to the OBD socket as the OBD socket symbol is flashing and the test will not proceed without it ?? Thanks +Regards

Hi, It has been running ok with the new injectors-these were an exact replacement , like for like. Cant use the self cal at the moment - connected it to pin 7 as instructions which is pink/black on mine but software shows that its still not connected --defo connected to correct pin. Regards

Hi, Tried to attach a screen print but comment came up saying `board quota reached' . Everything seems to be ok except there isn't an option for biogoti blue injectors -- its loaded as REG FAST (?) and should revs signal be `normal' or weak ? Thanks Regards

Thanks . Yes already done that but will repeat it. Best Regards

Hi, Thanks for your comment and it got me thinking it was ok yes. Replaced temp sensor thinking it was switching too quickly and upsetting the petrol trims (does that make sense?) but it made no difference. so as a test I started it on petrol and ran it up to temperature switched it over to gas and ...

Hi, Thanks for your response. have been getting all sorts of fault codes on the petrol ecu.. Mixture too rich , mixture too lean , O 2 sensors etc. system finally going into closed loop. . I have finally traced it to the lpg system `upsetting' the petrol side. Have re-set the adaptive values and its ...

Hello to all.
Could someone point me in the direction for OMVL Dream files for Range Rover 4.6 Thor Bosch Motronic?
The ECU needs a refresh and I can t find were I saved the V8 files.
Many thanks.

Does this still apply ??
The notes about oval sockets won't.
What might apply, all depends on what the lead was originally made/supplied for.
Might help

I guess "just installed" means a secondhand system, as you're describing ...

Thanks for your help. the diagnostics socket is an 8 pin socket with only 4 of the 8 pins connected.Does this still apply ?? Regards

:( First post on this site --hope someone can help.
Just installed a BiGas system onto a Nissan Almera.
I cannot connect my laptop to the ECU. The WTV interface appears to be connected ok --shown in device manager and software loaded is BiGas as supplied with the cable. Think i need to change some ...
