Distributor

Post by Cliffords »

Hi all

Has anyone got alternative distributors fitted ?

My car that came with no distributor was likely fitted with a Lucas 43DM4 unit . You cant get this now .
Our usual suppliers have no used units and I suspect if I am to buy new there are better alternatives .

If you have fitted something else and it works can you let me know please . Or any other thoughts .

Thanks

Not tried on a Lotus but on a Mini I used Simonbbc.com , might be worth a call to find out the options, I think (IIRC) the M4 designates the advance characteristics so there might be a close equivalent they do.

Thanks , what one did you fit ? Did you need any additional amplifier etc .
I will give them call too, but I don't have dimensions as I don't have the original one .

Thanks

I didn’t fit it, it was the PO, but it is the bluetooth version.
Everything is contained in the distributor so nothing additional needed.
Mine also has built in programmable Rev limiter and immobiliser. You can program mechanical and vacuum advance to match the original, or can adjust to fine tune if you want.

Oooh, that sounds good! I could see myself spending a lot of time flooring it from low revs, tweaking the advance as far as I can get it before it pinks. So if it's bluetooth, does that mean you can play with the curve via an app on your 'phone or something?

Yes, you can program both vacuum and mechanical advance via a Bluetooth app. Then when driving you can advance timing 1 degree at a time up to a max of 10 degrees IIRC.
When driving you have a dashboard on the app that shows live data of how much advance, vacuum, rpm, voltage, temp and GPS speed.

Total advance is what you need to be looking at, typically 34 to 36 degrees and then work back from that. At tickover its all static advance, I ve forgotten the specifics for the lotus engine cos Ive gone v8, but, weights and vacuum add about 11 degrees x2, so 22 degrees- ish, so ideally static needs to be at 12 to 14 degrees. Someone will chime in with the specifics but total advance is whats important.
Bear in mind Im not as bright as I look.
