Better economy, got rid of the POS MAF and went MAP which proved more reliable....

My previous Rangie also had a Haltech but an early one without ignition control. It, too, used MAP and had no MAF.

'Zackly!

Let me just say "MegaSquirt".

Less than $400 fully assembled, program it yourself with a laptop, just wire it into the existing EFI system and then disconnect the Lucas computer.

MegsquirtExtra gives dual fuel and ignition maps, both completely programable.

I built one and fitted it to a 3.5 RR, fuel only. Worked well, but then I upgraded to 3.9 RR.

Different wiring so I was unable to just plug and play.

I have rewired and was about to start tuning when my laptop blew up. Getting that fixed now.

My plan is to have it running Megasquirt for petrol and ignition, and have it changeover to ignition only for LPG when I press the LPG switch.

At a later date I might investigate having megasquirt run a solenoid via the second fuel map, to control delivery of LPG.
