I know the mileage is stored in the cluster, but is it stored in the pcm as well?

 

yes...

 

It may seem like a stupid question to ask, but I needed a definate. The "Auto Computer Exchange" people wanted to cut a deal with me since they already shipped out a second pcm to me which I paid extra to arrive by friday but didnt (if you haven't been following my thread). I ended up throwing my stock pcm back in and drove 3hrs home last weekend so I racked up quite a few miles. I was concerned about my mileage not matching up now which is the reason for the question. I probably racked up 300+ miles since I drove back here monday so since the mileage is stored in the pcm... it isn't worth me taking their deal to knock off some money as I don't want mismatched mileage on the truck.

Thanks dhvaughan for making the decision easy.

 

my mileage doesn't match and it doesn't hurt anything.
i replaced my cluster while chasing a speedo problem and so mine are 40k different.
