C/F and fibreglass is very brittle, be very careful when drilling as the bits can grab and make a rough edges. I'd recommend using a small rotary tool with a fine grinding bit. Just mark out the size of the hole and grind carefully. Should get a better result than a drill.

I don't like drilling carbon/fibre, because as people have said, it's brittle. But, bonnet pins for those bonnets are pretty much mandatory. I don't know how many times i've seen it where those carbon bonnets have flipped up due to flexing etc.

That's why I still run the stock bonnet.

yeah I'm not sure what man whore is reffering to, but I've never had any trouble. you want a good bit, in good condition with fine pitch. and a high drill speed. put masking tape over the area you want to drill. drill a very small pilot hole then away you go. I've uised this technique to drill from about 1mm thick to about 3 or 4mm thick. you can finish the hole a bit with a light, fine, round file.

      I’d love to find some where that can recover the dashes to look brand new and original. Mine has a very slight bubble, nothing compared to come I’ve seen though

      $170K. I asked one of the guys there as a joke if that price was just for the passenger seat as it was where the price sheet was... he tried really hard to crack a smile 😄 He also mentioned that every single part of the car was inspected and either restored or replaced with a new or as new part, or made from scratch. The interior was incredible, every inch like a new car.

      Time for a modernisation, throw out the AFM, stock O2s, ECU into the e-waste bin. Rip out the cable throttle, IACV, pedal, etc. into the scrap metal bin. DBW, e-throttle, modern ECU, CANbus wideband, and the thing will drive better than when it left the factory.

      I agree, don't go trusting those trims. As I said, first step is to put the logger away, and do the basics in diagnosis.   I spend plenty of time with data loggers. I also spend plenty of time teaching "technicians" why they need to stop using their data loggers, and learn real diagnostics.   The amount of data logs I play with would probably blow most people away. I don't just use it to diagnose. I log raw CAN data too, as a nice chunk of my job is reverse engineering what automotive manufacturers are doing.

      I'm aware, but unless you're actually seeing the voltage the ECU is seeing and you're able to verify the sensors are actually working I find it hard to just trust STFT/LTFT. I will say, logging the ECU comes naturally to me because it's one of the lowest effort methods of diagnosis and I do similar things in my day job all the time. Staring at 20+ charts looking for something that isn't quite right isn't for everyone. NDS1 allows you to log almost everything so that's normally what I do and then sort out the data later.
