Hey guys,
So heres my problem, i tune and my afr is just bone straight on. 14.7 idle low throttle cruise and 13 WOT or 12 on boosted apps. But the 2d fuel map is just all over the place. again car runs great afrs look great. map looks shit lol.
this is across 2 laptops 5 cars 2 s300s turbo not turbo stock injectors not stock injectors d series b series. im tuning completly out of vtec to avoid complications. either im forgetting something or im doing something wrong. and unfortunely ive searched and all ive found is people saying its fine but it should not look like this. i can manually smooth the map but then it runs bad and has bad afr. ive been running my cars for years on these ugly maps but they have all been spot on. Any and all help would be amazing.

No datalogs for these calibrations have been posted.

sorry spunkster I couldn't get new logs until recently. lost most of it have a new laptop now.
so I'm attaching a (i think) newer version of the Integra tune along with a data log and along with that a tune called v2 that i made some fueling adjustments according to the show estimated changes overlay. I tune using my best judgment, and the overlay as more of a suggestion or compass. I avoid using anything with low samples. At this point in the tune I'm only really adjusting the cells with at least 20-50 samples (in this instance a bunch of 1-5% changes) since I don't trust afr readings with a single sample or very few. ALSO I used to know how to change the sampling rate or like hits before registering a sample for the overlay but for the life of me I can not find it anywhere even googled the hell outta it.
My worry is as i continue to refine the tune the maps look uglier and uglier to the point they look like the map in the one listed old tune. I start with a stock p28 map so its not handmade. You can see in the load up tunes some areas it goes way up or down in a single cell but afrs look good and steady or maybe its 1% off. I just don't understand why they are so jagged when everyone else has smooth curves.
i plan on running the power for the wideband to a new location off switched power (haven't found where yet) and cleaning the thermostat housing ground to see if that helps at all. WB ground is at the ecu and the offset is currently - .43 wired into d14 Wideband is a lc2 so the scale makes it usable with the 3.73V limit.
Thanks!

I wouldn't rely wholly on the suggested changes you datalog. There is some artistic license you have to put on the tables to keep them smooth and within the range of where they need to be. They should never cross and should be relatively smooth and not go up and down in the same row. You may need to tune on the dyno to get the best results and measure the power output when making changes.
