front O2 sensor received and replaced..
wont have a real tangible idea of difference to mpg until a good week of driving but it made some very minor changes to the fuelling, and to pre/post cat readings. not really a lot but then every little bit helps I suppose before: after: has anyone else got any suggestions as to why my fuel trims are showing plus figures. or maybe a confirmation that those readings are totally fine? this is all at idle but I revved for a bit and the fuelling didnt seem to change. I'll check again next week but my understanding is 'long term' is only like 20 seconds or so beyond that really I'm happy to just leave it alone now, pending a test out on the longer roads it seems to be running perfectly. to drive it's smooth as silk and pulls well no hesitancy Last edited by stuart bowes; May 24th, 2021 at 22:15. |

So this is probably a total noob mistake but no-one else seems to have spotted it (or maybe just left me to work it out for myself)
apparently area 1,2,3,4,5 is not the different injectors, it's the different 'areas' of the map. 1=idle, 5= full chat, and 3 sections in between that now makes more sense looking at the gradual increase in values and it can allegedly take 3 or more drive cycles to recalculate I still feel like I should be trying to get them closer to zero, so I'm going to try a can of WD40 and see if that shows up any air leaks around the inlet anywhere interested to know what other peopls's fuel trims are, especially anyone with a N/A 2.4 who gets decent mid 20's urban or good solid mid 30's overall Last edited by stuart bowes; May 26th, 2021 at 00:51. |

did a bit of A road driving to try and access all of the fuelling map and give it a chance to re-calculate
now showing 1 - 0.93 2 - 0.93 3 - 1.02 4 - 1.09 5 - 1.12 so not much change from previous I did ask around about the 140-170 remap, and there's a place near me who will do it including dyno before and after for around £400 ... tbh that's a bit more than I was thinking I'd have to see an improvement of 3-4mpg over a whole year to break even on that, but it might still be worth it for the extra oomph. on my map apparently bhp flattens off hard at around 4.5k (Which to be fair I can feel when I try to overtake) and the newer map pushes on past that to 6k or so which is where the extra 30bhp comes in.. the bottom end of curve looks nearly identical.. it is tempting I have to admit this weeks mpg 21.5 but I have added roof bars, so keeping the same average is actually indicative of a slight improvement IMO. And although I did go on an A-road, let's just say I wasn't being economical Last edited by stuart bowes; May 26th, 2021 at 23:13. |

lol for the first couple of months or so I reckon that's probably very true, but the novelty would soon wear off, most of my driving is sub 40mph and it's hard / pointless keeping revs high in an auto at those speeds
and then when I am on a fast road, more often than not I have the family in the car and that tends to keep me in check not like the old days of sticking on some drum and bass, hop over two lanes and nail it |

exactly, and it would be backed up by and before and after dyno so it's not just some little kid with a laptop going 'i'll chip your car innit bruv'
Also the original idea was the newer map is reportedly more efficient down the bottom end which I use a lot more, but I'm not entirely convinced I still want to run it a while longer first to see if any other issues pop up or if I can get the numbers down in other ways plus, there's a numberplate I've got my eye on for about £600 and tbh that's more appealing lol Last edited by stuart bowes; May 27th, 2021 at 00:52. |

You might as well keep the £400, or spend it on something else in my opinion. Its a 2.4L petrol engine in a 20 year old car... its not going to be by any means economical as is, never mind with a remap. Get yourself the number plate instead, forget the remap.
