We're ripping out the old EMtron ECU and replacing it with....another EMtron ECU. The EMtron SL4 ECU did exactly what was asked of it and there is nothing wrong with it, but the more featured KV8 model gives us the ability to run a drive by wire (DBW) throttle as well as some flexibility in our Lambda/AFR sensor setup for the future.

Currently, the K20 swapped CRX is undergoing some repairs and strengthening to combat some of the cracks and tears we found in the body and chassis, in particular the front cross member. As all fabricators know weight vs strength is a constant battle and with the 255whp K swap in there now already tearing the car to pieces, it makes sense to not just fix but future proof the chassis in general let alone for the fact we hope to make a little more power from another build in the future.

The gearbox has also been problematic to the point the expense of a Holinger is actually looking like a 'cheap' investment. We have been very happy with the Holinger in the SR86 so far which was a heavy influence on this decision. Gear ratios are also something we can tinker with further here although that was one area the previous gearbox setup wasn't entirely lacking in.

Also up for improvement is a less sexy item, the clutch. Often overlooked as an improved clutch setup isn't going to give you any dyno bragging rights, if you're into such things, but it will help you pass others on the track regardless when you get it right.
