I have been starting to tune my car. its been about a week now. now im reading ---- about setting up a the 2.5 bar map i just put in crome that was the map im using and it ajusted according so can someone explane to me the proper way to setup the sensor.

 

bump i search everywhere

 

yea im not sure what the question is...you put in a new map sensor, so now you need to tune for that new map

 

ive started tuning but now it will only idle where i want it to sometimes. At first it will idle 15.2 were i set it for from the start but if i drive for a good 5 min it will idle at a steady rpm but at like 12.5-13.6 then it will eventully lean it self back out i didnt know if i would need to change my mbar collem to some thing else so it reads directly from that one rather then doing math between two. When i log the tracker goes back and forth between the 26-21 collem's but if i change the top number the car idles like ---- drives like ---- ect. Otherwise ive used autotune to get my ballpark figure then i fine tuned from there. I was thinking auto tune changed the cell but if the car sits for a while it will be fine.

 

Make sure your autotune settings allow it to make changes in 1st/neutral. The default settings usually don't tune idle IIRC.

 

thanx
