On the subject of efi using bike throttle bodies, here's my take on it. Using two sets of triumph motorbike throttle bodies complete with injectors and sensors, homemade manifold and adapted throttle linkage/cable. It runs and drives, but I still have to get the fine tuning done with tunerstudio.

I'm using microsquirt with edis for the ignition. Homemade inlet manifold and two sets of triumph 675 throttle bodies. I chose these because the come with fuel rail, tps sensor and injectors as a nice package which simplified things nicely.

Here's my take on the triumph triple throttle bodies. Engine running and car drives. Just need to get out and do some tuning, delayed due to family matters but hope to restart soon.

Nasty, on a positive, the magnetic plug works.

Yes I was aware that the tune will probably change with an airbox, but by the time I get round to making it, I hope to have learned a few things about the tuning and the retune should be easier. Just need to get my other jobs done so I can get out on the road for a bit of autotune.

Yes that is my plan. I just put some foam filters on for the time being. I want to get some tuning done first and tidy up the spaghetti under the dashboard a bit.

I have followed Mr Speedys example and used triumph 675 daytona throttle bodies. The spacing was dictated by paring up two sets of the bodies and being able to fit into the space once occupied by the carbs. Seems to fit OK.

Yes limp mode won't work without the microsquirt because it is also controlling the efi which would stop working. On carbs however, if the microsquirt stopped, then I think the edis would still operate in limp mode.

I was going to use the pi hardware with a single throttle body, but then came across a different solution here on sideways. I'm using triumph motorbike throttle bodies. As I said earlier, car now runs and drives, but is still running a bit rich and still needs tuning. I have used your pi tables as a starting point, but obviously the ve table needs refining in my application. I am using a Spartan 2 wideband and have just started using autotune. A few more trips out will hopefully refine things a bit.

I could have used external coil drivers or even coils with built in drivers, but I couldn't find any for 6 cylinder, edis seemed to be a cost effective option with lots of experience about. When I set it up with ignition only, it was relatively straightforward and yes, the limp mode works with microsquirt, this was used to check the edis and timing was set right before connecting the microsquirt. I have now fitted the throttle bodies and fuel system and the car is running and drives but I have the tuning still to do, still learning with this but I'm getting there.

I am using a Vauxhall coil and leads hooked up to edis and microsquirt. Seems to work OK.

Yes the diode fits in between the alternator and the warning light. The banded end on the diode connects to the alternator side. John

I have just had the same problems as you have had, first with the plug leads needing changing around and then engine not stopping when switched off. I hopefully have sorted this by fitting a diode in the circuit from alternator to the warning light. I used a SR5100 5A 100V Schottky Germanium Rectifier Diode 5 Amp, sourced on the Internet auction site. My car is converted from dynamo to alternator with the regulator control box removed and the smaller wires for the ignition light circuit are joined together at this point, so I fitted the diode here. Seems to work fine, engine stops when asked to and the ignition light still functions correctly.

I originally fitted one of Chris Witors sports systems to my 2000mk1 together with the 6 2 1 manifold. I found the system a bit noisy, especially as I was planning to do the RBRR, so changed the straight through centre pipe to the semi sport which has an additional silencer. This made it much more acceptable while still having a sporty sound.

Hi John I did mean towed car, (slip of typing finger) and yes I agree with your comments with regard towing weights. Fortunately our 'Tow' vehicle, our motor home, has the capacity to safely pull the cars we use as towed cars.
