Selling the SpeedyEFI PNP I've been running in my NB for a bit over a year now. No issues with it. I was driving my car on this board up until my new ECU was in hand.
I have modified this board by adding signals so the ECU intercepts the AC signal. This allows the ECU to control when the AC compressor engages and allows for AC idle up.
The Check Engine Light has also been wired up which I used to signal if coolant was too cold/hot and for oil pressure warnings.
I will provide details on that to whoever buys this. I have done a writeup on here about AC idle up, so that can be referenced as well.
The harness to the expansion board has been cut to wire in signals to the auxiliary inputs.
This board does have a Bluetooth module installed as well which has been really handy for datalogging and using a phone like a digital dash.
$250 Shipped in the US. SOLD I am going to keep the programming cable, so you will need to source one. They are a very common USB-B/Printer cable.
