It doesn't look like you are using the original C4 computer at all. Does ABS, cruise control, ASR, and AC all still work?

I'm planing on converting mine to CNP but EFI Connections said they didn't know if it would work on a C4.
Did you have any fitment issues with the hood??
Which coils are you using??

I've been using MSX3 for about 4 years and running wasted spark without the opti, which I have removed about 10 years ago. Now I want to convert to CNP, without my EDIS 8 that's all.
About to order the D585 coils, that's why I asked about clearance issues on a C4.
