The Magneti Marelli Dinoplex was one of the first commercially available automotive capacitive ignition systems on the market and was quite ahead of its time. The Dinoplex C electronic capacitive discharge ignition was developed by Magneti Marelli in 1967 for Ferrari race cars, development continued in 1968 for the high revving Dino V6 engine (hence the name Dinoplex). Dinoplex units have been installed in a range of racing and performance street cars from the late sixties to the mid eighties, including the Ferrari 312, Ferrari Dino 206 (the first Ferrari with an electronic ignition) and 246, Ferrari Daytona, the Fiat Dino Coupe and Spider (the first production cars fitted with a Dinoplex ignition), Lancia Stratos and the Lamborghini Countach.
This is a non-commercial website which aims to provide helpful documents and information on how to diagnose problems, repair, restore and install historic ignition units made by Magneti Marelli. Use of the included documents and information is at your own risk. Working on ignition systems requires good electrical knowledge and application of the required security precautions.

Dinoplex C "C", "D" and early "CA" models were fitted with a metal housing for the Normale/Emergenza switch, later "CA", "CB", "DA" and "DAX" models came with a bakelite switch housing. The Normale/Emergenza switch selected between the capacitive Dino ignition (Normale) and a fallback Points and Coil ignition setup (Emergenza) in case the Dinoplex should fail. In most setups the tach was only functional in the Normale setting and disabled in the Emergenza mode.
Dinoplex C "E" and "EA" models were supplied without switch and Emergenza/Normale wiring, also there are no screw holes on the side for the two wire clips as in the "C" and "D" models.

The first Dinoplex ignition unit build. Only a small batch of units were produced, this type and the 101 DAX are the rarest model of the Dinoplex C series. Components and PCB were an early, simpler version of the later Dinoplex C. The enclosure is equivalent to the very first C type ignitions, except that it has no switch and three short wires with a three terminal AMP/TYCO male connector. Some AEC 102 units had the electronics potted in epoxy. The type description was stamped into the casted enclosure, unlike Dinoplex C units where the type description was part of the cast and is embossed. The first two series were painted in yellow, the last series was natural silver. Original units can be identified by the stamped type description and the correct text and serial number application.

Marelli AEC103A ignitions have been produced from 1970 to 1975. Another batch was produced in 1978. This batch can be identified by the enclosure cast, which has no serial number and the cast is a bit more rough than the original batch. The AEC103BA type featured two connectors to easily switch between the Normale and Emergenza (Fallback) mode.
All AEC103 units are potted in epoxy, making a repair very difficult.

Rare custom made ignition for F1 race cars, deployed from 1975 onwards. This ignition was also used as replacement for the Dinoplex AEC102, such as in the Alfa Romeo T33/3. The circuit board is an early version of the AEC104B ignition, Marelli apparently tested their new ignition in race cars this way before they launched it as a commercial product.
The ignition accepts trigger input via points or a magnetic pickup in the distributor, depending on the version. With a magnetic pickup the spark triggers on the rising edge as soon as the signal level reaches ~1V.
This is the first Dinoplex ignition featuring a rev limiter. The limiter was installed as piggyback module on the main ignition module, this setup was also used for the AEC104B-660 and AEC104B-780 later on.
Early versions are painted black and can be identified by the single Marelli Ignition Sistem for Racing Car logo label in yellow, later versions also had a red aluminium type label with the type code and serial number, as well as a round warning sticker labeled "90 C - MAX - 194 F. The rev limiter had its own Magneti Marelli label, which was silver in earlier versiond and yellow in later ones. Last versions made featured a blue Magneti Marelli label similar to the one used on the AEC104BK.
Next to the race type there was also an OEM version in unpainted aluminium finish and featuring a Raceplex label on the rev limiter. This version seems to have been sold as an aftermarket item.

The AEC104 BK was the first production ignition in the Dinoplex series to support a magnetic pickup (variable reluctance) trigger. All setups with a magnetic pickup trigger the spark on the rising edge as soon as the signal level reaches ~1V.
The B-660 and B-780 types also featured a rev limiter which was mounted on top of the Dinoplex base unit next to the resistor module. All AEC104 ignitions are potted in PU and epoxy. ^top

The SAE701A ignition is a fully electronic hybrid digital/analog mapped inductive ignition controller custom designed for the BMW M1 car. As a predecessor of the Marelli Digiplex series, the SAE701A is probably the first mapped digital ignition control unit ever installed in a production car.
When planning the development of the M1, BMW first wanted to deploy the same ignition setup already used in their F2 car. Since the M1 needed to be street legal for BMW be able to sell enough cars for the homologation, BMW decided to go with a fully mapped ignition setup to ensure meeting the strict emission control requirements. Bosch was not able to supply their first version of their Motronic engine control unit in time for the launch of the M1, so BMW then talked to Marelli following a recommendation of ItalDesign. Marelli was choosen as the supplier and developed the SAE701A mapped ignition.

The Microplex series was Magneti Marelli's third design of a mapped ignition controller, preceded by the SAE701A and the Digiplex. It was also the last Marelli engine control unit deployed by Ferrari with the exception of the Marelli IAW series as in the Ferrari F40 and 288.
With the earlier Digiplex, one unit could only handle a maximum of four cylinders, so two units were required for an eight cylinder car as in the Ferrari 308 GTSi/GTBi. A single Microplex is fast enough to handle up to twelve cylinders, so just one Microplex unit is required for an eight or twelve cylinder car.
Later Microplex MED120 units tagged B/D featured a simple serial port for diagnosis with a handheld testing device called Ferrari Tester, made by Magneti Marelli.
Magneti Marelli Distributor S125
Cars with a factory installed S125 Distributor:
Dino V6 based cars with a Magneti Marelli AEC 101 or AEC 103 ignition
S 125 A - 15 (1967-1968): 3 cams, two sets of contacts, early Fiat Dino 2.0 Spider and Coupe
S 125 AX - 15 (1967-1968): 3 cams, two sets of contacts, early Ferrari Dino 206 GT
S 125 BX - 15 (1968-1972): 3 cams, two sets of contacts, Ferrari Dino 206 GT and 246 GT, Fiat Dino 2.0/2.4 Spider and Coupe
S 125 C (1971-1975): 6 cams, two sets of contacts, Ferrari Dino 246 GT/GTS, Fiat Dino 2.4 Spider and Coupe, Lancia Stratos HF
The Magneti Marelli S125 was the default distributor for the Dino 2.0l/2.4 V6 engine, the 15 degree number after the type number denotes the maximum cam shaft advance. S125 A type distributors are the earliest type and were installed in early Fiat Dinos with a points and coil based ignition before the Dinoplex was introduced. S125 AX type distributors were installed in early Ferrari 206 GT's. S125 BX were produced between 1968 and 1972, a second batch was produced in 1974. S125BX distributors produced up to April 1969 had a silver on red label, for the rest of the production run the labels were red on silver. The S125 C distributor was introduced in December 1971 and also featured a 15 maximum advance, but this was no longer mentioned on the type label.
The S125 rotor turns counter clockwise. Turning the distributor clockwise will advance the timing, turning it counterclockwise will retard the timing.
S125 A, AX and BX type distributors have a three lobe cam with two adjacent set of points wired in parallel to reduce point scatter and enhance dwell at high RPMs.
S125 C type distributors have a six lobe cam and feature two independent sets of points for emission control equipped cars. In the emission control setup, the first set of points (R1) was always active, and the second set of points (R2) could be added by switching ground to R2 via a microswitch (which was installed on the left Weber carburettor) when no throttle was applied.When idling this setup retarded the idle advance by 5.5 (camshaft) for better combustion and cleaner exhaust gases.
S125 C distributors have the same body as S125 BX distributors but are easily identified by the second hole for the additional R2 contact terminal on the left of the distributor body.
For supporting the points based emergency mode in a Dinoplex AEC101/AEC103 setup, a 0,25uF capacitor was installed on the S125A/AX/BX body (two on the S125C) and wired to the points terminal. The Dinoplex ignition itself does not require a capacitor wired to the points as it uses the points setup only to trigger an ignition. The original capacitor supplied by Magneti Marelli came in a brass colored metal enclosure which was embossed with the Magneti Marelli logo, a production code (as example CE29T, ES29S) and the specification 0,25uF and 500 Volt.
