I wish I had bought this a long time ago

Amazing product. Makes tuning easy and quick. Endless functions. Now I can control and log 2 wideband sensors, a boost controller, water meth and any thing I can think of through inputs and outputs. So much superior to tuning a factory ECM.

Great capabilities but..

HLY-554-114
The unit cannot drive standard coil packs without "drivers" (554-123) for them. Why these circuits were not built in is a mystery. The coil packs make wiring a mess. The wiring harnesses themselves are rather odd in that some wires from one harness will go all the way back to the ECU to jump into another harness. This makes wiring a mess. You can re-terminate the ends of the harnesses, shortening them up, but it is difficult. I know that they are trying to make a product that works for all applications, but it seems that the harnesses required for use with this product could use some work. The documentation for custom I/O could use some help as well. I would also like to see a dedicated alternator control output. ...read more
