Tricky its about time u jumped on it...
@candon nice work...
I'm not 100% sure, but I believe the 98 blackbox PCM is able to control the fans to some extent, however you will need the PCM properly tuned for it. I don't think the 96-97 blackbox PCMs can though.
It looks like a lot of you guys who have swapped over to E fans are doing it on pre 95 trucks. What options do I have for a 98 Tahoe? Mainly ECM options. Does my OEM ECM have an option to control E fan(s)? I do NOT want E fans to negatively effect the performance of my A/C.
My concern is I don't really know the pros and cons of doing an Efan conversion. I have seen some people hook up the A/C to the Efan and I don't know why.
