after my rebuild i def. want to get it tuned pretty decently because A) i don't want it to blow up again B) i want to get all the power i can out of all the money i just spent. i know the best way is to dyno or get a wide band (too much $$ right now), but seeing as the closest one is pretty far away this really isn't an option. i bought a datalogger which i hope will help me a little bit and i should be able to tune the fuel pretty good with the sfmu and safc. so how should i go about doing it? logging on a graph rpm vs o2 voltage or what? also, how would a wideband be hooked up to a datalogger, can i just get the sensor and log it through there or do i have to buy the whole setup. someone please put some opinions.
