What aspects did you ask to have them customize? I know that they'll sell whatever pieces you want so you don't need swallow stuff you don't need and you can mix and match all of their billet pieces to get the look you want which is really nice.
But, when I asked about changing the outlets on the top they indicated that I'd need to do it. No problem, I think I can manage that. I then asked them about supporting the LS heater control valve (i.e., the one with a built in heater bypass) that I and a lot of other builders use. It uses a slightly different version of a motor actuator from the same Chinese supplier. Their response was that they don't have a bypass on their LS or I could get a new radiator or re-plumb. Not really an option for me. Both actuators are 90-degree valves with the same electrical plug and it would be a pretty simple matter for them to check with their supplier if the ECU for both actuators is the same (that would result in a plug -and-play swap). They didn't have any interest in checking.
So, they were responsive, but not willing to call supplier to ask simple question. In any event, I bought one of their valves and I'm pretty sure that I can solve this by printing a 3D part to covert their shaft to the valve.
Lastly, I read the instructions very carefully and noted that the Bluetooth and manual controls are mutually exclusive. Not a big deal until there is an issue with something and you can't control the air. I have a coffee/espresso machine that's controlled via Bluetooth. It was engineered from the ground up for Bluetooth control, but I run into control issues from time to time. Fortunately, it has some small override switches.
The RestoMod instructions indicate that you need to do the following to switch from Bluetooth to manual.
*must close out Bluetooth connection from your device
*LED on ECU will change from double flash (connected) to single flash (not connected)
*Connect jumper to calibration port to use manual controls
*LED on ECU will light up (you can now use manual controls)
The jumper can be replaced by a hidden switch, but there is no facility to remote the LED. This type of design would seem to indicate that the Bluetooth was an afterthought. I asked if they would come out with a new ECU (which I'd have to pay for) that would get rid of the need for the above process... guys that I spoke with really know A/C, but they don't know software.
I'm leaning towards doing it. So, I'm really curious about:
*what customizations you're planning on
*if anyone has experience on how stable the Bluetooth control
*thoughts on the A/C unit itself v(i.e., s. Vintage Air)
