Hi
 Thanks for quick reply. I am looking at using a single injector only
 as a performance booster on an old diesel motor injecting small
 quantities of petrol. Was going to use TPS to vary injector output,
  4 x pulse outputs off the crank.Thought that the 555 was a good
 place to start playing.

 That should work.
 Most diesel run WOT all the time and the amount power and fuel flow
 is controlled by the TPS. You'll get smoke like at a tractor pull :)
 Make sure you use the CMOS version of the 555.

 Scott,
Are you planning to use gasoline or diesel fuel? Gasoline has a major problem
 with the high compression and WILL cause knock. I would use propane or CNG
instead if that is the case.

  Lost efficiency?? Please explain. I am confused.
