Tuning box/ remap for LPG (autogas) converted UK XH Hemi??
Hi guys, so as the title suggests I'm looking for a tuning box for my XH Hemi, that is LPG converted. I want to be able to recalibrate a larger wheel size and then thought it would be fun to try and gert some more user friendly performance out of the Hemi!
However I have spoken to a number of companies including:
and unfortunately NONE of them can support an LPG converted car!! Sometimes I hate being a UK Jeep owner, we get none of the fun stuff that you guys get over here, or we have to pay through the nose for it!
Anyway from my research, for any XH owners who are thinking of tuning boxes, a few companies.... Bully Dog, Hypertech, Jet Chip say they do support the XH version but when you cut to LPG all memory will disappear as it flips from the main ECU to the LPG system. I do not know enough about the switch over between the two systems so can't say one way or the other and most of my driving is done on LPG as with a 5.7ltr petrol over the pond would drain my bank in days!! So I appear stuck..
I have four questions really:
1 - Has anyone with a LPG converted XH had any successful experience with tuning boxes?
2 - Has anyone with a LPG converted XH had any experience with professional remaps - I didn't want this necessarily as you can't change it once you've done the remap, you're stuck in that setting? I may be forced down this route if it is even possible.
3 - Has anyone with a LPG converted XK had any experience with tuning boxes? I'm interested to hear if it worked.
4 - Does anyone with LPG experience have more knowledge on the LPG ECU and how it links to the main ECU and therefore how it would be affected by a something like a tuner connected to it or remap.
