Thread: Programmable Ignition Timing

Richard, when you setup your locked distributor, what static timing point did you set the distributor to? The Black Box instructions say 0 degrees in contrast to the 70 degrees indicated for the VW application. I'm pondering the necessary distributor phasing questions.

After you lock the distributor re-install it at 0 degrees.

Then any timing figures you put into the Timing MAP are the actual figure before TDC, since it's referenced back to the 0 degree initial.

FrankGRUN, do you have the Black Box ignition ready to put in?

Richard, Just about to do install but a totally different system to yours. Ford 460, TFi distributor to Black Box to Crane Hi-6s to Crane Fireball coil to FiTech throttle body EFi. Trying to map 42 degrees of maximum advance into the angular space of the TFi distributor rotor.

That sounds quite complicated. Hope you can work it all out.

Hi, reallly like all the information posted here. Thanks Richard for your maps you posted and the wiring of the Bosch module. l am new to programming ignition timing but have a CB Black that will install soon still trying to workout how to set the distributor static timing it currently set to 16 deg do l still set static timing or do l need to set it to zero and let the cb black box advance the timing in the map l set up?

You need to set static timing to 0 degrees, and lock the mechanical advance, and remove the vacuum advance.

All advance of the timing is controlled by the Black Box. The MAP numbers are the actual timing figures for any particular rpm and load.

If you type in tool (or tools, can't remember) into the first page that opens in the Black Box software you can force the whole map to one timing figure. There is no box to type it into, just type it while that page is open. Then with the timing forced to one figure you can use a timing light to check the advance. Change this figure again to check 10, 20, 30 degrees etc. with the timing light.

Sorry been away for a while, just got back.
