Re: Pending fault codes P1171 and P1174, tuning advice needed please

Sorry only just seen this for some reason I didn't get a notification.

Got it ok I'll have a play. Thank you.

Ah I see, I thought auto calibration would shape the map. It does drive really nice on lpg now with now codes so it can't be far off I think.

Re: Pending fault codes P1171 and P1174, tuning advice needed please

Hi Simon, thanks for the reply but those figures in the table now are from the unadjusted map straight after calibration not from the latest screenshot on here. What would you prefer? All the same data in the chart but complete and upto date with the current map? I can get what ever data you need an...

Re: Pending fault codes P1171 and P1174, tuning advice needed please

Ah ok I missed the 146 figure. I guessed the 147. Maybe worth trying 145 in the 12.50 row? There will still be only 1 peak then. The fuel trims changed from 40% and up loads. Most of the data for the fuel trims and pinj is in the above screenshots and table. I'll have a look tomorrow to see if I can...

Re: Pending fault codes P1171 and P1174, tuning advice needed please

Just been for a short drive watching the fuel trims. They have gone from -5 to +8 so I reckon I need To change the 135's in line 12.50 to 147. Then line 15 change the 130's to 134.

What do you think?

Re: Pending fault codes P1171 and P1174, tuning advice needed please

No not draining it again, that took ages to get that out. The filters are new. I stopped at 1.6 bar as that was what i was happy with, it still had more adjustment but I'd rather not max it out.

I've had good results that I'm sorting through now but will post shortly.

Re: Pending fault codes P1171 and P1174, tuning advice needed please

Hmm I'm sure it's constantly high when running on petrol.

I'll clean it out, increase the pressure, run auto calibration then report back.

Thanks.

Re: Pending fault codes P1171 and P1174, tuning advice needed please

Ah ok. I don't have the land rover specific gear unfortunately.

Yes got my current settings saved. Would just have to lower the pressure as well. Hopefully this new setup will be better so no need to revert back.

Re: Pending fault codes P1171 and P1174, tuning advice needed please

My trims are pretty decent so won't need resetting. I have access to snap on diagnostics but don't think I need them atm. Should be good to go by the time I get home.

Does the above sound like a good plan?
