Could this be because of an exhaust leak in the connection to either engine or overpipe?
Here are the datalogs, there are 3 short trips in one log.

Any help/info would be greatly appreciated!
Thanks! |
something weird is going on with the logging, at times, looks more like logging issue that car issue.
connect you oft to internet and let it upsat make sure your on latest version of openflash manager 1.21.0 i think.
then try logging again
high ltft doesnt mean you running lean it just means the ecu is applying a lot of correction to try to get the correct afr, this couls be due to bad maf scaling due aftermarket intake or exhaust leak ect or wrong fuel ie e85 on a petrol tune.
parts of log look ok but then some parameters are weird ie iam=0 and then ltft -100, thats impossible max is 30, looks like logging problems
