Injection conversions often do not include any timing advance processors.  Because of LPG's and CNG's higher octane numbers (105 & 120+ US DoE AFDC), the absence of engine knock will cause the vehicle's PCM to run the full programmed advance at all times.  While this may not be the ideal timing advance, the injection conversions typically get much better fuel economy that fumigation conversions.  AEB makes a variety of Timing Advance Processors for vehicles with computer-controlled ignition timing and the TAPs currently available are:

 

AEB Timing Advance Processor Applications
AEB549 – JOKER N
  • 3, 4, 5, 6, and 8 cylinder cars fitted with computer-controlled coil ignition system and distributor system and distributor that works directly on the negative coil of some types of electronic ignition systems.
  • includes GM 7/8-pin HEI modules, Ford TFI
AEB515N – PUMA
  • 3, 4, 5, 6, and 8 cylinder cars fitted with computer-controlled coil ignition system and distributor.
  • includes GM 4-pin Vortec HEI modules
AEB510N – COBRA
  • cars fitted with an injection-ignition system with an inductive type PMS sensor.
AEB518N – PANDA
  • 3, 4, 5, 6, and 8 cylinder cars fitted with an injection-ignition system with a HALL effect CKP sensor. It can advance 2 HALL sensors (CKP HALL + HALL phase).
AEB511N – SPIDER
  • cars fitted with an injection-ignition system with a Hall-effect type PMS sensor.

AEB's older TAPs are obsolete. AEB stopped discontinued their AEB526N (Wolf-N) TAP (distributor advance electronic ignitions) on February 10, 2016 and AEB531 (Platinos) TAP (breaker-point ignitions) on 16th January 2014.
