In need of data for ignition curve R5 GT Turbo

[Okido]

Hello turbo enthusiasts,
I have a Renault Rodeo. A car based on the Renault 6 and that has the same chassis as a Renault 4. Now I have planted a Renault 5 GT Turbo engine in it. Because I do not have a triggerwheel and sensors, I can not use the standard electronic ignition. I like to use the 123-ignition and it seems that it would work well, however I can not find anywhere the default data to make a curve. If I have a standard Renault 5 GT Turbo curve, I can finetune it from there. Anybody know something or know how to get those figures?

Thanks in advance,
Ido

We have some guys with standalone who i'm sure would give you a shot of the ignition grid, but you must have a pickup for the engine position surely? I have just looked up the 123-ignition site but it doesn't state how it works, or how it defines crank position?

It defines the the top dead center by a fixed point when you install it. Just as with a normal distributor you put the flywheel at top dead center and then you move the distributor untill a led goes on. From there you can feed the 123-ignition with any grid by the computer with a USB-cable.

Interesting concept, have you used it before?

Obviously any ignition information you get here will be bespoke to the car so please use conservatively

@TNT Andy would you mind taking a screen of your ignition grid?

I will keep your advise in mind. I had used it before on a Renault 5 TX engine and it worked very wel. But for a Renault 5 TX you can get the data for the curve you need from any manual you can find.

does it have vac or pressure compensation? sounds very interesting. where is the pick up? in the dizzy?

 

[Okido]

It has vacuum advance and boost retard. technical data 123-ignition

cool stuff, i wonder how it calculates where in the cycle it is?

I couldn't find any data on the internet for the Gordini turbo.

The 123 ignition has a programmable advance curve and programmable vacuum curve (which allows negative or positive pressure). It would be like a default map without any fuelling or throttle position info. Someone must have a starting point for advance versus rpm and advance vs vacuum.

I've got a Rodeo 1A with the 850cc engine. I think it is the only one in the UK. Would be interesting to see photos of your build.

I know of a chap called Paul Cunningham in the UK with a Rodeo, I dont know what trim/spec it is though!

With the ignition curve wich I have programmed I can run with full throttle. Without boost at lower revs, there is little stammering. Idle is irregular and sounds like a rallycar. So it just needs fine adjustment. Here is the map I made:

Thanks thoug for your help.
Your Rodeo 1A - a nice one by the way - is so far as I can see, a MK1. There is also a 1A MK2, depending on the place of the gasfiller. MK1 = at the backside; MK2 = at the right side.
My Rodeo is the 2B with standard the Renault 6 engine (1108 cc).

That's a great little conversion there @Okido!!

With that engine you sure are riding more horses in your Rodeo...
:facepalm:

The car is running well now. The seals of the CO-adjustment screw and the seal of the idle jet were not in order.

Yesterday evening I out-sprinted a Audi A5 sport coupe, who was provoking me. My wife sitting next to me found it hilarious. Probably the nerves and excitement, but she just couldn't stop laughing.

Very good, any pics of the setup?
