Dealer Reflash

[TheCampo]

So I am at the dealership and asked them to check my ECU version.

They came back and told me an upgrade is available.

I told them to go ahead with it. Hope this was a good decision.

I am sure the car had the original map on it. Any one have any experience with this?

Better hope it's not the 4807H or 4907H ECU upgrade ... car will have less snap and you'll regret it.

How can I find that out.... Dealer had no info on which flash I had, I didnt ask if they knew which one they were putting on but doubt they did.... I have a dashhawk but from my knowledge I cannot find that out.

I do find the car drives ALOT better. Less backfiring and havent had a fuel cut yet... Granted have not taken it on the highway and ripped it since. I am overall happy with this new flash.

True, but the hesitation is gone. I had mine reflashed and the car drives better overall as a result. Just throw the AP on and you'll never know the wiser!(drive2)

They need to look into your fuel pump then. The reflash is the first step, then the fuel pump is the next.
