th350 free speedo fix problem: who wants to do some math for me?
alright I just recently swapped a th350 into my z28 that used to have a 4l60e. I went ahead and spliced the abs sensor up front for the free speedo fix. my problem is that my hptuners will not accept the 1.175 as a valid gear ratio that i'm supposed to tune in. the smallest ratio it will accept is a 2.00. I suck at math, so I ask you kind folks to figure out for me what tire size i need to plug in to make up for the difference in the gear ratio. I am supposed to have a 1.175 gear ratio and 26" tire to make my speedo work correctly. so what tire size will i need to plug in with a 2.00 gear ratio to get the same end ratio?
thanks,
Steve
