I am going to be ordering an OBDI conversion from madz28.com and will have them recalibrate my speedo. I've heard that motive 4.10's are actually 4.11's, is this true? What should I tell Ion I have, 4.10's or 4.11's or if there is a difference, will it be noticable?

Thanks

 

I have Gm Motive 4.10's i have also heard the motives are actually 4.10, where i really dont think there is a huge difference in speedo calibration between the 4.10 and 4.11's i would explain to madz28 that you have the gm motive 4.10's and that your're unsure of if they're 4.10's or 4.11's, he is a smart guy he should know, good luck!

I have motives 4.10's and if you actually figure out the math on it it comes out to 4.11111111111 So actually yeah it technically is 4.11's.
