Csi Dizzy Worth It? 45D For My 1130

Are tbe CSI programmable dizzys really worth the money?
I wanted a minispares evo dizzy to match my evo001 cam profile, but they're out of stock and apparently have been for a while.
For £120 more I can get the CSI dizzy. With the pre built in curves.
My other option was an Aldon Yellow, but for the extra few quid I was tempted by the option to change the curve.
In an ideal world I'd buy an AC Dodd recurred one, but id imagine this relys on Me taking highly accurate readings of my current dizzy.
My car isn't anything crazy it's
1130
Evo cam
Hs4 carb
Standard 45d dizzy
Freeflow manifold and rc40 exhaust
12g202 head standard
9.1 CR static
Thanks, Luke

H&H Ignition re-curved my 45D for my 1220 under consultation with my local RR tuner (John Nutt).
My wife's 1330 has the evo cam and the MS dizzy. Good combination. Why not ask MS if they can tell you what the curve is as they can't supply the dizzy.

That sounds ideal. Yes I guess I could ask them, see if they're willing to pass that info on.

The CSIs are great, I've got them in a quite a few cars now, but they are very hard to justify the cost of. It's not just that they have selectable curves, but the way that they deliver the spark to the coil, you get a hot and fat spark, no other system I've tried comes close.
For most use though, a recurved distributor is usually best value for money.

Thanks Spider,
I've just read this topic you wrote which made me more inclined to choose a high quality dizzy, with a known curve.

If you google it they have some videos on YouTube, you keep your standard dizzy and go from there. Good luck.

I run an accuspark stealth black box 2. It's a unit you wire in between the coil and dizzy and you can set your own advance curves with it, and it can hold 3 maps, also you can adjust it on the unit, no computer required. I've had it for nearly 2 years now, no problems. You can adjust it to your hearts content.

Hi Isto,
There's actually a deal on at the minute and they're £170
For the stealth 3. Doesn't seem bad value for money. How did you find the 3 maps already installed?
I coincidentally watched some of those videos tonight. Once thing I wasn't sure of is actually making your own "nap" as such.
Is it just a case of stating what advance you require at set rev ranges? Can you also still run your vac advance?
Cheers,

Are CSI curve maps based on a 1275 engine . It would be wise to 'map your current dizzy anyway: something like - static, advance at 1500 / 2000/ 3000/ and all inWOT ( some dizzies keep advancing until quite late in the rev range)
The more unique your engine the more likelihood that it responds slightly differently to standard curves - CSI and other selectable types give you lots of choices to help find "your map" - whilst tuning ( skilled guesswork) of older type dizzies is getting those springs to deliver that perfect curve.
Quality of spark throw, (and sparkplug gapping) can make a difference - and so matched coils/ dizzies etc are also a consideration.
I have a CSI dizzy and it works well.
I have a number of individually curved dizzies ( not an AC Dodd one - but I suspect his are first rate)And they work well
I have some module type internals ( had a poor experience with ALdon Yellow many years ago) but most perform well
I would also add to the list of Considerations
The Distributor Dr - ( mine worked well- racecar sold) and
and Aussie suppliers
Performance Ignition Services - SCORCHER dizzy - bosch type not lucas - and worked well
PeakIgnition ( all one word) - his website is under construction but give Lindsay an email) and guesswhat ----????? worked well

Glad you found that handy.
The likes of a CSI are possibly more of value if you are planning on doing a few cam swaps and things like that.

I'm actually really liking the idea of the Accuspart black box 3. Essentially as @Isto mentioned its a box that connects in line with the original dizzy. You can pre set your own map and retains the vacuum. It also has a rev limiter which would be sensible for me having a 1098 crank. So I could limit it to 5500 rpm.
The cons I see though are that you have to lock your advance on the original dizzy with wire and also as it retains the original dizzy, its dependant on the dizzy actually been in good condition. I could get a cheapo lucas repro dizzy and lock the advance and use that, but then the price would be similar to that of the CSI.
Its £170 at the minute and the CSI Is around £230. Both on Sale.
I'm doing more research and weighing up the pros and cons so I've appreciated your help
