Goswell Posted October 7, 2005 Report Share Posted October 7, 2005 I've heard that the EFI from a 5 series BMW is virtually the same as those being supplied today for the TR6. Does anyone have details on what it would take to fit it and get it working, assuming I heard correctly. There is a large number of these BMW's being taken to the crushers these days.

Guest harry dent Posted October 7, 2005 Report Share Posted October 7, 2005 That is a new one on me Barry.I would like to find out more,like you EFI does interest me. Harry. Quote Link to post Share on other sites
F69 Posted October 7, 2005 Report Share Posted October 7, 2005 Barry, what you say is, I believe true. When I bought my TR6 at TRGB in April 2003, the boss Gary had a white TR5, which had just been restored to his specifications and when he showed it to me I am certain the the injection system was BMW. A simple phone call to Gary on 08707-572441 will answer your question, I'm sure. Quote Link to post Share on other sites
Goswell Posted October 10, 2005 Author Report Share Posted October 10, 2005 Thanks for the info I will give him a call. Bye the way the name is Dave, no relative of Barry although the Goswell clan isn't that large. Quote Link to post Share on other sites
Martti Ojanen Posted October 10, 2005 Report Share Posted October 10, 2005 I do not know about BMW EFI installation to TR6 but I am starting my own EFI project. This winter I will install a fully programmable EFI and direct ingnition system to my TR6PI. I use HESTEC controller (see HESTEC homepage). I am using BOSCH injectors from BMW and one large trottlebody also from BMW. I will report my installation in detail on my webpage. Keep you eyes open.

Guest harry dent Posted October 11, 2005 Report Share Posted October 11, 2005 Hi Dave and all, Spoke to Gary TRGB and his set up is the Webcon EFI not BMW and fitted to Webber inlet manifolds.He has tried the original injector manifolds bored out to accept the Bosch injectors and found a huge flat spot.His research has found that the injectors need to be further away from the head ports to atomise the fuel properly.He is still researching. I know there is kits made for the purpose but they are hughley expensive.It can not be rocket science to produce something less expensive.Everything is EFI now. Regards Harry.

Goswell Posted October 11, 2005 Author Report Share Posted October 11, 2005 Many thanks for your inputs I think I'll avoid this route to EFI sounds like it's hard work. Shame really as I can pick up BMW units for £200, with some work. Quote Link to post Share on other sites
Guest harry dent Posted October 11, 2005 Report Share Posted October 11, 2005 Do not discount it Dave.Chris Connely of Mass Engineering is doing work on this using original PI manifolds.I am sure we can pool our knowledge and get something sorted between us all that will work.

hoppy Posted October 12, 2005 Report Share Posted October 12, 2005 Check out:- http://www.bgsoflex.com/megasquirt.html I have had one of these fitted to my TR6 and a mate has one fitted to his TR4. My car uses the original manifolds bored out to accept Bosch injectors with a vauxhall (carlton) throttle body and a Lambda sensor fitted in the downpipe. The car returns over 35mpg on a run with no detrimental effect on performance. Graham. Quote Link to post Share on other sites
Guest harry dent Posted October 12, 2005 Report Share Posted October 12, 2005 Hi Graham, Any chance of some photo's and cost of your conversion. Harry. Quote Link to post Share on other sites
Martti Ojanen Posted October 13, 2005 Report Share Posted October 13, 2005 Goswell, when considering using BMW EFI unit you should find out if the unit is programmable (suppose it is) and how you could re-program the EFI unit to suit TR6 engine.

hoppy Posted October 13, 2005 Report Share Posted October 13, 2005 Harry, Megasquirt cost approx £150 plus labour to build it up, mine was built up by a mate so that didn't cost me. I Quote Link to post Share on other sites
hoppy Posted October 13, 2005 Report Share Posted October 13, 2005 Hi Harry, Will try again, don't know what happened to the posting.................The Megasquirt cost approx. £150 plus labour to build it up, I'm not electronically minded so had a mate do it. The manifolds I machined out myself but it only took a couple of hours, so that shouildn't cost much at a machine shop. The throttle body,injectors and idle sensor came from a Vauxhall Carlton from the scrapyard for £50. The system that I put on two years ago was purely from the Carlton , but that gave problems on tickover so a change to Megasquirt was decided on to improve matters, (the mate who buit up the megasquirt E C U had already fitted one in his Dax Cobra, so we knew it would work). I will post some photos when I get home this weekend. Graham Quote Link to post Share on other sites
jean Posted October 16, 2005 Report Share Posted October 16, 2005 I think we should not compare BMW injection with EFI system RTR sells. These are two complete different systems. The Lumenition and Webcon Alpha are designed for competition cars and allow a vaste amount of settings. I doubt that anyone will be able to lay an hand on the BMW software to calibrate and map the ECU. This is one of the best kept company secrets. As far as I know it is not anough to drill out the Lucas throttle bodies to fit electronic injectors. EFI injectors work in a different way. While the Lucas injectors work once per cycle, the EFI injectors open and close a few hundred times per second. The percentage of time the injectors are open has to be in accordance with the engine requirements, this means big engines big injectors, so not every injector is suitable for a TR6 engine, that's why the different injector colours. There are by the way several systems available in Germany based on Bosch EFI working with a single throttle body. For those interested here is the RTR Lumenition EFI on a TR6 Jean Quote Link to post Share on other sites
Guest harry dent Posted October 24, 2005 Report Share Posted October 24, 2005 Any luck with the photo's Graham.If you are not too far from me is there any chance of having a look/drive of your TR. I live in Hertsfordshire. Regards Harry. Quote Link to post Share on other sites
hoppy Posted October 24, 2005 Report Share Posted October 24, 2005 Hi Harry, I've got some photos, but am having difficulty posting them on the forum, if you e-mail me then I can send them direct to you.I lam located in north Norfolk. Graham. Quote Link to post Share on other sites
jean Posted October 24, 2005 Report Share Posted October 24, 2005 Graham, if I can do it every one can. If you resize the picture to below 60kb, copy it to your doc file, to find it back, you can add it to the post via file attachments. It's a piece of cake Jean Quote Link to post Share on other sites
