Are you ready?

My ECU went into Pre-Order status. I am expecting to start shipping mid May of 2016. I'm so stoked about these!

I have been running mine for the past couple months now. During this time we have found a couple areas that could be improved and made changes before the production boards where made. These improvements include some indicator led's on the main board itself for visual reference of the comm channels and the main power input to aid in any troubleshooting and just to know power is getting in. The coil drivers where re-positioned to allow for better mounting to the case, and finally some adjustment to a couple traces on the bottom of the board to allow clearance at the main board mounting locations. I can't tell you how excited I am about this :)

One of the coolest parts about this ECU is the internal wideband controller. I installed this right beside the Innovate LC2 so I could get that side by side comparison. Come to find out it actually provides data just a bit faster than my LC2 is through the CAN buss using the Innovate serial chain. That was a great sight.

In the graph below you can see this. The Pink in the 3rd row is the internal wideband trace where the Red is the LS2. Green in the same row represents the average of the 02 sensors at the 4 ports. This sensor is also set to a lag of 100 which uses no filtering on the signal. If you look at the traces you can see it goes full lean quicker and it also starts reacting first to the reintroduction of fuel. One last thing to note it the long delay form the port mounted 02 sensors to the collector mounted sensors, about 1.5 seconds or 1500ms. You have to take this into account when using autotune (veal), otherwise you will be correcting the current cell for something that happened 1.5 seconds ago...
