Hello,
Why do you want to go with a Motec? This used to be your only option 2-3 years ago - but this is not longer the case. To install it you have to completely hack your wiring harness and install a crank trigger which is a little tricky and important to get right. It does provide you with complete control over just about anything you want and is rugged.
There are less intrusive options. The Roe Vec2 does a pretty good job on fuel and timing if you stay away from 100% duty cycle; AEM compares to a motec feature wise and plugs into the stock harness.
If your looking for some basic fuel tuning you can go with the Vec1 or Apexi S-AFC.
good luck,
Dave.
A Motec EMS is nowhere near "intrusive" and you don't have to "hack" your wiring harness. It can be put back to stock in a couple days, by someone who understands what they are doing.
The Motec interface that SVS has incorporated into all generation Vipers is extremely professional and the integration is seamless. A crank trigger set up is simple and not at all tricky when done by someone with experience. We are testing a system right now that will possibly eliminate the need for a trigger wheel.
As far as I know AEM hasn't released an EMS for the Gen3. The only way to get it done is to try and use the version for the plug and play specifically made for the Gen2 and "rig it" into the Gen3. I would call this more of an intrusive situation because of the fact that the Gen2 ECU/Body computers and the Gen3 ECU/Body computers communicate completely different. The SRT-10 ECU/Body computers communicate with greater sophistication compared to a Gen 2 set-up. So if it is plug and play for the Gen2 then you have to hack it apart and try to make it communicate with the SRT-10?
Basic example: Gen2 gauges are all analog and Gen3 are all stepper valve controlled which send a completely different pulse and are harder to communicate with. If you don’t have the optimum precise amount of control of what you are incorporating into the electronics of your Gen3 80k Viper then you will have ASD relay problems. You could be driving along and your Gen3 Viper will just shutdown. Why? Basically because something isn’t communicating properly and the ASD relay shuts the car down. This is only the tip of the iceberg.
When you take an AEM plug and play EMS and place it on a Gen3 Viper, can you then plug in the DRB in order to determine what might be a potential miscommunication between the ECU and the body computer? Or does the AEM tell you everything that the DRB would? The way we interface with a stock system is seamless and the DRB doesn’t even know the Motec is there.
AEM makes a plug and play unit for a specific year and model vehicle. These units are tested for that specific vehicle.
Motec gives you a universal system that handles a higher level of sophisticated controls, with unmatched data logging capabilities and can be incorporated into any vehicle.
I believe a Motec EMS on an SRT-10 forced inducted engine has greater capabilities of running the entire car with better precision and less problems to deal with.
You will end up in the same ballpark $$$$ wise.
