SDS ignition map for L28ET


Recommended Posts

On a stock L28ET (or stock compression anyway) I was running 20* initial, 36* total, all in by 2750rpm. Boost retard was 1* per 1psi boost to a maxium of 15* retard at 15psi boost.

 

This worked quite well with the stock P90 head setup. When I upped the compression on my motor I had to be a little less agressive with the timing.

Do you have the specs for the start up I'm having trouble with mine I need to lean -20 every morning to start it off and then put it back at 0.

 

Do you still need this?   I have Drax's old 240 and he included a note pad with all the values written down.   I briefly looked for it, but couldn't find it.  If you need it send me a PM and I'll dig it up and post it.
