Yeah, I have an AEM sitting in the garage... Not alot of info out there. The AEM forum has very little (other than a base map) to offer vipers. Currently off the car and using a Cragin re-flash until it becomes a higher priority...
it is cheaper and you'll enjoy the car most if you have pro tune it for you. you can learn about it and change little things but doing full tune correctly is not a easy. Also it cost lot less to pay a tuner than getting new motor, this could very costly learning process. Depends on where you are, but i have know a very sharp tuner. Just pm me if you want his contact number.
also, drivebility is hardest thing to tune. if you think about it part throttle is 90% of driving.
I don't know how well other vipers drive with their AEM but I'm ready to put my car up against any other viper with aem and compare the drivebility. I have pretty damn well tuned viper.

If you want to learn tuning its best to not start with a $25-35K engine that could punch a hole in the block due to a fragged piston pretty easily. A spun bearing would be bad but punching a hole in a block that costs 9 grand from Chrysler + the cost of the rebuild starts to add up to a pretty hefty price tag at the end of the day.

9k from chrysler. 1-2k from ebay.
But I'm curious to hear from the 'experts' on this one: how will you f-up a N/A set-up with an AEM if your base tune is similar to the stock tune and all you've done in modify A/F and timing?
I mean c'mon... you guys are scaring the DIY people. On a N/A set-up, it is no different than tuning with a VEC (albeit more complex).

A N/A motor with forged pistons is almost impossible to blow up due to tune. You don't have nearly the cylinder pressure of a Turbo system.
The operative word here is "almost". I had a kid that had a rep for AEM tuning locally "tune" my racecar. I figured the same thing....N/A car...base map and tweak it. Well, he did something to melt piston #3 and 10. Parts of the piston were rattling around in the manifold. LOL. I take part of the blame for trusting the guy w/o getting references. You live you learn. I tend to learn the hard way.

I don't mean to scare any DIY tuners, the fuel system that will debut in about a week or two will prove that we're all for the DIY tuners. That coupled with the AEM kits should be all anyone needs to tune a car up to say 1500hp
Its just that even with an NA setup inexperience can kill an engine.
when you've never done it before.
but it's a waste)
