Dual carb set ups - ?

Quote:What about your distributor ? Is it the OEM one or it has been replaced ?

OEM by the looks of it mate.

Quote:I believe that if you have the OEM one it can't work without the ECU in order to have a non-vacuum advance timing ...

I thought, but I might be wrong that the timing could be fixed at something like 35 degrees even with the stock dizzy? Again I don’t know enough about this to be sure.

Quote:Don't know exactly which sensors the std.ecu uses for timing, but maybe there is some RPM based limp home map present in the ecu..probably brought back to normal specs through the base timing.

The engine check light is currently on, so you could be right with that judgment.

Quote:Without a decent dizzy with vacuum advance or iginition computer you are probably leaving 20hp unused..wouldn't be amazed if the car produced less power then stock.

Thing is mate, the car is rapid so it can’t be down on power. On track recently the car happily kept up with a 307bhp Cosworth powered 4wd Peugeot 205 on the straights, so the AE86 definitely has some legs on it.

Quote:Lots of complicated and less complicated iginition computers on the market. I would suggest choosing one and having it tuned..should be around 300-500 pounds if you have it tuned by someone else on a rolling road.

Thing is for the time being its working fine and I am happy with the performance so don’t really want to get a new ignition system if the existing one is working properly, just want to remove what isn’t needed. When I rebuild the engine for high compression then I will probably look at an aftermarket ignition system. I presume by ignition systems you are referring to things like the MSD 6AL?
