Can I also get a clock in landscape view? That would make it five stars for me!

DOES NOT WORK WITH NEWEST IOS

This app makes it easy to develop and save ignition curves. The virtual gauges also help you measure the accuracy of your tach and speedometer. Block temperature is useful, as is ammeter and volt meter. Switches easily between vehicles and allows unique access codes.

The new tune feature that allows timing changes while the engine is running works great. Can tune the engine in half the time now.

A thing of beauty!

When I bought the unit new I was able to set a custom curve, and now it never even reads it so I can’t make any adjustments to the tune. It always connects via Bluetooth but sometimes the gauges work and sometimes they don’t.

I’ve been using the 123 blue tooth distributor on my ‘76 BMW 2002 since November 2020. Th unit replaced my trusty tii pe vacuum advance Petroniux distributor which I have had for over 20 years and never let me down. Let me tell you that this is one of the best upgrades I made to the vehicle due to my engine set up. Having side drafts require more advance so having the ability to change the timing is a God send. The first thing I noticed is the smooth cold start. Carbs stink in the winter especially Weber DCOE’s without choke cable. With this unit the cold start is effortless. Also the gauge function, GPS speedometer are great because my original Speedometer is definitely off. Thank you 123 for upgrading the gauges with digital tach and curve. I wanted to provide that feedback a long time ago but forgot and voila you added that great feature on the gauge. Today I just happen to notice it it wasn’t there yesterday. All I can say is this is a great ignition upgrade but make sure you use the correct coil. I am using a new Bosch blue coil instead of the resistor and blaster coil I used for the Petronix system. The only other improvement I can think of right now is to improve the clips that hold the cap. They tend to come loose and the cap can come off. For now I pinch the clip to make it more secure but it does loosen with time and vibration of these carbed motors.

Runs good but when you shut down then restart it looses the tune. I’m not getting anything from the vacuum port either so no advance there. I may be doing something wrong but there’s no way to be sure as the instructions are not very good. It’s wanting to work but it doesn’t probably something simple and I am open to suggestions and will update the review accordingly
