a/c idle up question

Post by fast930 »

ms3 extra running 2.6.14. my a/c idle up feature was working flawlessly until yesterday. i am using the n2o in as my signal to the iac. for some reason the n2o line has 10.4v power and if the idle up feature is activated regardless of the n2o is connested to a power source my revs go way up. this line should not have power as its a "line in".hopefully someone can help thanks

Please be sure you do not have JP8 connected on the MS3X card.

thanks for the reply Matt and it was nice meeting you at THE MITTY. we were running the porsche ms3 K3 935. ive made no wiring changes and the idle up circuit was working fine on the 930 for over a year.. i know its crazy. ron is going to check it out on the bench tomorrow.even with the big power #s im running its nice to have a/c here in the tropics!
