The datalog does not show the problem you are describing. WIthout that it is impossible to say what the problem might be. Has this been properly tuned yet? Have you discussed this problem with your tuner?

HI spunkster, many thanks for your repply, do i have to make a new datalog? i was thinking that maybe there is a problem with temperature or with TPS, due to car bogs at low rpm's. If this datalog is useless for you please let me know how to do a proper one im gonna do. Well motor was tuned in a dyno, but motor has been swapped to another car here on europe I've tried to contact tunner but is kinda slow answering so im trying this way.

you need to provide a datalog that shows it stalling.

Yes, sir im gonna do that, I've checked on s300 manager with my map and i want to turn on datalog manually there says, that i can use the scs connector, so like getting error codes should i plug a wires on that connector and drive normally?

im very sorry for the stupid question but i don't have any previous experience with this things....

Yes you can use that input, but it would be much easier for you to just keep the laptop with you and datalog directly to capture the problem.

Hi!

do you see anything wrong in datalogs? maybe tps is not adjusted properly?

car runs great at high speeds.... but... but driving at low speed is a real nightmare

That looks ok, you may want to try manually adjusting your TPS to get it to correct closer to 0 though.
