This is the 3rd G-Dash I've purchased & used. I've been using AIM products for a decade, starting with the old Pista systems, then an Evo 4 with a MyChron dash. Most recently I've run the G-Dash on the pair of Spectrum / Honda FF cars I own. The dash I purchased on this order was for a Van Diemen RF-01 FC car I prep for a customer. We bought it to replace the AIM steering wheel display that was already in there. Mainly we needed a smaller wheel. The basics on the dash: Size: Very compact dash. On all three installations we mount them on the steering wheel and even with the small Momo wheels the fit is very good. Customization With mutli-color LED's and AIM's excellent software package you can set up any sort of alarm or indicator you want. Color, steady, slow flashing, or fast flashing, and an extra "pop up window" message can all be set in software. Buttons One of the things I hated on the MyChron & Pista dashes was that when you're wearing gloves the buttons are bit tricky to find & actuate. Not so with the G-Dash! Switching pages is very easy to do while driving. The AIM Steering Wheel has better buttons (and an integrated PTT switch), but the whole package is pretty bulky in a modern formula car. Display AIM went with VERY LARGE characters for the display. In spite of the small screen size reading things is very easy. If you opt for a lap time display the lap time will take up the bottom half of the screen. Again, it's a godsend when you're on the track & you need information quickly. Compatibility May favorite thing about AIM is the fact they already have presets in their software for a variety of popular fuel injection ECU's. This means with, say the Evo 4 and either a Zetec or a Honda ECU getting full engine data is a matter of hooking 2 wires up to the AIM system & selecting the ECU preset from the menu. Then make up your mind which page you want a given data readout on & set your alarms & shift lights as desired. Durability So far I haven't had many durability related issues. AIM's products seem to hold up very well to the routine abuse of being in a race car. Even in open-cockpit cars the G-dash holds up to the weather. I haven't tried immersing them in water, but if that happens with the car it's likely the dash working is the least of my worries. Known Issues The biggest things to watch out for on the G-dash are properly routing the interface cable and making sure it's tight. I've had the cable come loose a couple of times. The Evo 4 will still log data, but you have no gauges. Loctite is not a bad idea. Make sure you use the rubber vibration dampers when you mount the dash. Otherwise the vibrations are likely to cause damage.
