488 Lucas Distributer maps

Based on the work undertaken by ggzilla of a map file generator spreadsheet. I have taken the Lucas distributor lists published online and built the data into a excel based calculator, there are 195 distributors with data on makes and models to which they are fitted. The methodology uses linear inte...

Rev-limiter operation

Ok, let me get this straight; normally the trigger is low (off) and the SMBT... does not conduct, making the gate -ve via the ground link. then when trigger'd the SMBT conducts and the makes the gate +ve which stops the flow through the MOSFET. is that correct? i am trying to modify this arrangement...

The hard rev-limiter is a good idea, they were not in production when i bought my unit, should have waited and the new one would have come out; as its still awaiting installation.

immobilizer control of VRS signal

i'm trying to put to gether an immobilizer using an iButton and 08M picaxe (12digit serial key, with 8pin pic logic programmed with the relevent serial numbers). My plan is to place a solid-state switch of some sort at the junction where i'm attaching the additional cable to the VRS line. with a sim...

I cant comment on how it will run, as i've yet to fully commision my re-build. however reading down to 400 theoretically should not be a problem as the advance wont tailoff to a random number but work at the lowest rpm bin. it should be noted that the EDIS module will spark at rpms down to about 50 ...

At lower revs the compression comes on slower which means there is the possibility that the mixture will not fully burn, the repetative spark means a fuller/more complete burn should be achieved. This improves both power output and improves the emissions of the system. This should be a real boon for...

This feature is one i'm very interested in, i've started looking into methods of achieving it using separate hardware, an achievable method is to use a CPLD to create the apropriate signal using the input from the MEGAJOLT or any other ECU and a toggle to activeat / deactivate. This feature is of pa...
