Is it possible to update my ECU in the future?
I understand that the knock sensor is not 100% full proof. I did not spend time yet to find where I can program custom input output, is it because it is not available by the software?
Thanks

The way the knock control currently works for ECUs already out in circulation is an unused pin can be assigned for this function. You will need to use an external amplifier, i.e. JLS or other brand that has a knock output. Then it is easily enabled in the current software.
The new generation of ECU will have the knock built into the box. When this product was originally developed we opted to not include knock b/c in past experiences knock systems can be temperamental if not set up properly. I.e. noise from external devices, like a rattle from a loose clutch spline can trigger a false knock. Since there has been so much interest in having this as an option we are going to put it in. If proper time is taken to set it up and it is used without leaning on it too much it can work fine overall.
We can currently offer the EFI X5 (aka 4.0 ECU) with
dual-knock, dual-wideband, staged-seq injection, pit limiter, internal EGT, and many other features if someone needed these advanced features. These are the units we currently use for BMW dual-VANOS engines and other applications. We can set this up for a Lotus if someone were interested.
