quick question on my tune

[ricknbird350]

i have a 95 ta with an 4l60e. just had it dyno tuned with the stock 3.42 rear end in it. i just now put a 12 bolt in it with 4.10 will this affect my tune other than the speedo being way off?

it shouldnt change anything. i dont think it will change the speedo either

[ricknbird350]

anytime you change gears your speedo is off. think about it with 4.10s the driveshaft will be spinning more times than if it had 3.42s

I believe the wheel speed sensors are what sends the signal for vehicle speed not the driveshaft

[ricknbird350]

the vehicle speed is detected threw the speed sensor located on the tailshaft of the transmission. it runs off a magnetic pick up on the output shaft. the abs sensors on each wheel are only for abs and tcs. :shiner:
