Anyone using an AEM ems on a Gen III Viper

[KaiPL]

Anyone out there using an AEM engine management system on a Gen III Viper?

It's a lot more expensive than a VEC2. Is it worth the extra cost?

I know of a few cars that are. The problem last time I checked was that there was no plug and play system for the SRT yet. Heffner, [******], and and maybe a couple of others have done it.

Heffner has done it, you have to send the car to him to get it done.

I thought i heard something about the AEM being able to be used as a traction control unit to, is that wrong? If not what makes the AEM unit worth more?

Well, assuming you get it to work for your Gen III, the AEM offers much, much, much more flexibility than the VEC2. Yes, the AEM has traction control, as well as a 2-step rev limiter, built in boost controller, wideband oxygen sensors, available knock sensors, inputs for, I think 5, exhaust gas temperature sensors, and many, many more options. The AEM allows you to have total control over engine functions, whereas the VEC2 lets you add/remove timing and add/remove fuel. I know the VEC2 has a few extra slots you can use for nitrous or other device, but nothing compared to the AEM. I had the VEC2 on my Gen II with a big cam. The VEC2 just didn't allow enough adjustment to make the car drive close to stock. The AEM can handle just about any engine setup with the right tune. The only drawback to having this many options and functions, is the complexity factor is way up there. Unless you've had a good deal of experience tuning a stand-alone ECU, it's best left to the pro's. The VEC2 is pretty straightfoward; check your a/f ratio with some widebands, go to the dyno and add some timing to maximize your power before any pre-ignition, and bam, you are ready to roll. I'm not taking away anything from competent VEC2 tuners. It's not like you just tune it to perfection in a matter of a couple hours. It still takes time, experience, and some basic knowledge of the tuning process. Compared to the AEM, the VEC2 is a simplified approach to engine management. Ok, AEM isn't paying me for the plug on their product, so I'll stop now.
