Hi Simon,
Thanks for the reply.
I'll drop Tinley Tech an email and see if they'll supply the software.
It looks as if the BRC software is now for free general use as the later versions of the software don't need a key.
Thanks
Julian

Hi all,
Not been on for a bit but on the scrounge, possibly!
We have recently replaced my partners MG Ztt with an E46 328 BMW with a BRC Plug and Drive system which was fitted at the end of 2017.
I'm trying to remap the system as it changes to gas at too high a temp and runs poorly once in open loop ...

Hi all,
Not been on for a while and looking at converting another car (probably a Volvo V70).
The last one was my E38 750 which has run like a champ for 45000 miles which Simon was very helpful with.
I can lay my hands on a complete BRC Fly SF system for not a lot of money and would like to fit this ...

I have finally finished my conversion and can confirm it is running well.
It is lumpy on changeover but a bit of tweaking should iron this out.
The map also needs a bit of a tweak at higher injector durations but this is not a problem as I don't need to rev this thing or give large throttle inputs ...

Simon,
Thanks for your invaluable help.
Have you got a tank (680 x 270)?
Cheers
Julian

Hi,
Have you got the dimensions and the date stamp?
Cheers
Julian

Forgot to say I had another look and measure up tonight and the MJ reducer should go in the void between the headlight and airbox and the ECU and emulator will fit in the enclosure where the brake fluid reservoir is.
I can also feed the switch wiring and the diagnostic connector through from here as ...

Hi Simon,
Thanks for the reply.
I managed to download a wiring diagram for a BMW 850 today as I couldn't find one freely available for the 750.
The injectors are batched in triples as follows 1, 3 and 5; 2, 4 and 6; 7, 9 and 11; 8, 10 and 12
Each set uses the common triggering earth from the PCM so ...

Hi All,
Has anyone got a 670 x 300 Toroidal LPG tank for sale which must be in date ideally a 4 hole with Multivalve or if not single hole?
A 670 X 270 may be an option but only if it is very cheap as I want to maximise my capacity.
Cheers
Julian

Hi Simon,
Thanks for all your help and sorry to be a pain but can you check what I have below for the correct configuration of the injectors and Emulators?
LPG Injector order is for ECU controller connections and E is for the corresponding Emulator connection.

Rear
Cylinder Firing LPG Injector ...

Hi Simon,
Thanks for the reply.
I have decided to go for a single controller with another emulator (Stag2-E6), Valtek 3 ohm injectors (as I plan to run these in parallel so effectively 1.5 ohm) and a single Magic Jet 3 Compact reducer.
Thanks again for you help
Cheers
Julian

Had another thought and wondered if this is possible due to lack of under bonnet space.
Could I use one 6 cylinder controller and an emulator for the other 6 cylinders and then wire up the injectors in pairs in parallel in sequence of firing order?
I'm still looking at 2 reducers but may just go for ...

Thanks for the response Simon.
I guess I am hung up on injector speed after converting my RX8 so a high performing injector isn't required in this application due to it's low output per cylinder?
Thanks
Julian

Hi Simon,
Thanks for the info.
I was looking at KME reducers as they look very small but what you say about the Magic jets make sense.
I suppose I could use one solenoid tee'd off into two reducers.
What are the Magic Jet injectors like? As good as Hanas?
Yes this car has 2 Engine modules controlled ...

Thanks for the reply Simon,
Yes 750's are about 320 hp and I was thinking of one compact reducer up by the firewall on the drivers side as these is a bit of space there but will have a good look at 2 smaller ones in a different location.
Do you have any recommendations for 200hp compact types?
Yes ...

Hi all,
I am on the brink of buying a BMW 750 and intend on lpg'ing it.
I have previously converted an RX8 and a BMW 540.
Has anybody on here converted one and what kit did you use?
I know I have to have 2 6 cylinder kits so was looking at LPGTECH having had good results on the Mazda along with Hana ...

Thanks for the reply

Hi All,
I've just bought a very tidy Alfa 147 which has a SGI 2 system on it.
It runs well (returning about 32 mpg on gas) but I want to have a look at the mapping as there is hesitancy above 5000ish rpm I would like to get rid of. Below this it's fine.
I have downloaded the software but I need a ...

Your slider has disappeared as you are in Standard not Tech calibration parameters.
The reason for the ignition loss error is because the car stalled while on gas so no wiring fault or whatever. This will always happen with LPGTech and you just have to clear the errors/log when you next have a look ...

Alfa and BMW state that 1l per 1000km is acceptable!
I use about 150ml of 2T per 350 to 400 miles (again about 2500 miles per litre) so this would have a negligible effect on the cat (SEE ABOVE).
