LPG -> Petrol conversion ECU programming


Recommended Posts

I'm new to PCMtec but I've been researching for a while prior to my conversion. I've got a LPG BF MK2 I'm converting to petrol, I've got a matching petrol ecu (LPG is ASU-223, petrol is ASU-222) as well as all the running gear.

I'm just wondering how I should go about pairing up the new ECU. I understand you take the original tune and compare it to the new ECU, just wondering if there's anything I should look out for when I'm doing this being it's LPG->Petrol.

Also wondering if it's necessary to merge the two files or if the Forscan parameter reset is sufficient? I'm guessing it is necessary to copy the VIN etc. but just wanted to clarify.

 

Going to save backups of each tune just in case. Any help is greatly appreciated!

As long as the ASU-222 is from the same vehicle variant eg ute, sedan, wagon, territory, auto, manual, BTR or ZF6 etc, the strategy should be correct. If it's not, the strategy will need to be changed. I assume it is because you say you have all the petrol running gear.

BF don't care if the VIN is correct or not, so not important if it's not changed.

If the strategy is correct, you don't care about the VIN being incorrect & the rest of he VID is the same eg speed source, cruise enabled, diff ratio etc between the 2 PCM's, all you need to do is install the petrol ASU-222 & run step 2 of PATS, module initialisation. No other PCM programming would be needed.
