Has anyone used one of these
Swiftune CSI Electronic Distributor
If so are they any good and do they make much diffence on a road engine

I have a thread running on this topic already, I will update it when I've fitted it later this month

Cool that would be great .
I was just wondering if it was a lot of money for what it was .

I have been running a few of these, though I obtained them from Mini Spares, I think the ones from Swifty's only suit Race spec engines.

 

For this style of Dissy, I recon they are pretty good, a bit pricey though. We've put them through some pretty harsh conditions (high heat (53+), water - as in river crossings around 1/2 metre deep) and had no problems, though I did fully seal them before fitting.

 

I do tend to think though that the Acuspark Stealth maybe a better option, as it has (almost) infinite programing options and turns out possibly cheaper (keeping in mind the Stealth doesn't come with a dissy), though the Stealth also does not have Vacuum Advance.

 

It would be nice if the guys developing this stuff would also include a Knock Sensor input.

One of the Mags did a test and fitted one to a standard car and they remarked it ran smoother

Cars will run on lots of different dizzy timing, but the optimal is often unique to the one car/ variant/ component set. The standard advance curves are representative and probably a bit conservative... The mappable timing or the pick a curve timing dizzies (such as csi or 123) give you a good starting point to find the OPTIMAL curve for your engine/driving conditions/ petrol octane rating etc with the added benefit of being able to change it if something alters.. example octane rating of available fuel.

The real problem is, how to find the optimal curve .........  dyno or RR and regraphing of a dizzy works  so too does having 16 curves to pick between( mostly)

So

if you like tinkering and tuning and listening and feeling your engine response.. then CSI/ 123 work great as do the mappable sytems

if you don't but want the right curve , get it sorted on a dyno and regraph and set once correctly  

whatever you do once installed, check the curves against a good timing light...

 

I have a couple of CSI a standard aldon yellow, and a rebuilt, regraphed electronic one....and they are all good, and probably all a bit more expensive than i would have liked but not shockingly so
