Ok i did the 2.3 ho intake mani. swap on my 96"2.4 and now i need to upgrade to a 97+ ecu so i can use hp tuners to get rid of the check engine line code for the egr. I have a 99" ecu right now if i was to swap that in to my 96" z24 would i have to change the knock sensor or any other sensor to accomadate the 99" ecu or would i be better off useing a 97"-98" ecu with that harness? I was told i could repin my ecu but i dont want to mess up anything so if theres any one in the Waukesha,WI area that would give me a hand please let me know.
Ok this is getting kinda anoying. Ive been on this site since a year after it got started and i see this stuff happen all the time, People come on here all the time who dont have sig's on the bottom of there page and get ignored all the time. And the people with them get there questions answered ALL the time and half of them are STUPID questions to begin with. I looked and really couldnt find what i need and thats why i posted this, i dont post stuff cuz im lazy i post cuz i cant find what im looking for.
A lot of people where right about this site, it SUCKS!!!!
you havent looked hard enough. its been 2 @!#$ days since youve asked your question and this is the first time ive seen it.

its not hard to swap the knock sensors around if you need to, but if the plugs are the same then you shouldnt need to swap sensors at all.
