have a b18a1 in 95 cx hatch stock pr4 ecu has a nice 1800rpm idle. its a high idle but its smooth. when i put my chipped p05 in the car the idle bounces. it also has a bouncy idle with my basemap chip in a chipped p28. i have no idea what this could be, my tunner doesnt even know. any help is greatly appreatied.TIA

 

If it does the same thing in two different chipped ECU's than I would say it has something to do with ether the chip itself or base map saved on it.

Check sum removed? Have you tried your base map on a different chip?

 

check sum is removed

have not tried the basemap on another chip yet

weve tried like 4 different basemaps and all do the same thing

gonne try a new chip when i get one
