- A look at installation and setup of the Classic Retrofit CDI+ ignition upgrade unit. This video includes details on how to fit your CDI upgrade and how to check timing before and after the box is installed.

Optional Distributor Locking:
While all of our CDI units will run on the factory ignition curve set by the weights in the distributor and deliver several key benefits when installed in this very simple way, the video also includes details of how to lock the distributor weights with our optional fitting, should you want to pursue the opportunity to run your air-cooled 911 (or any car using our CDI unit) on a bespoke timing curve. You can also catch a glimpse of what to expect when you connect the box to a windows PC to adjust the timing curve.
The video also shares a peek at our prototype ignition coils, which we will be releasing in 2020 as a superior upgrade to the current range of replacement coils, most of which seem to be very unreliable. There's also a mention of our new Technical Forum which launches next month.
Exciting times for Classic Retrofit and we hope you are enjoying these videos! We are open during the pandemic and shipping products daily.

I’ve got 1 year and ~ 7k miles on my CDI+. Noticeable better behaved at low RPMs and functions flawlessly. Now I’m saving my coin for an A/C unit, I know my wife will appreciate everything but the cost.
Finally got around to installing the CDI+ (and coil) in my recently restored (engine, paint, interior) 1970 911T (Leaf Green). It was indeed a straight swap and the car fired up first time and I immediately noticed the difference - very happy. Now to get the fuse panels sorted, but that's a bigger job for another day.
Good to know! Enjoy!
Is the really high pitched noise from the first start-up coming from the old box? Mine does that as well... But everything works perfectly.
Yes classic Bosch CDI whine. It is normal and the lack of that noise is how most failed CDIs are diagnosed.
Can you explain, for newbies, why you did the bespoke timing curve on the app? What's the purpose, etc? Thanks!
Adding a custom timing curve can improve engine performance.
Nice video and thanks for the upload. I am running your rear fuse panel on my 1977 911s (2,7). I added it after I rebuilt my engine a couple of years ago. It's only a small part but is really nice quality and I will be adding the rest of your ignition parts ASAP. Would you recommend that I upgraded my distributor to an electronic one too? I am still on the original (rebuilt) Bosch with points. Cheers, Jason.
Hi Jason, thanks for the positive comments. You could replace the points with electronic ignition - that is a definite upgrade. The Pelican forum has plenty of information on this.
Been following your product line, great additions! How would one improve an 86 turbo engine with a twin plug distributor for improved reliability with your tech? Currently running 2 msd 6AL ignition modules, could i replace with two of your units (ea coil)? Can i somehow retrofit a timing retard when the intake temps reach a certain temp? Also have you thought about using a BT app for tweaking or loading new maps?
I just downloaded the latest version of the CDI software and I am not able to connect my laptop to the cdi box. I am doing an upgrade to a long neck intercooler on a ‘78 930 turbo and decided to update my cdi firmware to prevent the 930 overheating shutdown issue. I am able to communicate with the cable and I updated the cable drivers that came with the software update. It gets to the point of ‘Connect to CDI’ and I plug in the cable with the black wire to the bottom of the box and then turn on the ignition on and nothing connects. I’m starting to wonder if somehow the box got reset or corrupted in the work process of installing the intercooler… not sure? How to test beyond that if I can’t yet run the car (it’s apart), and how do I connect to update the firmware ? Help greatly appreciated.
Hi David. Shoot us an email and we’ll figure this out.
Do you offer a fitting service for the cdi unit?
You should be able to fit this yourself but any decent Porsche specialist can fit it.
Most CDIs will eat the resistor in the Bosch rotor over time. I would either replace the rotor entirely with a plain rotor without a resistor or grind out the resistor and solder in a piece of wire in its stead.
No need to do any of that. Our CDI+ is 100% compatible with the standard rotor.
@@ClassicRetrofit The Bosch resistor rotor is a known weak link with CDIs. This has been historically true. (very popular with the VW community to remove the resistor for this reason) The resistor can fail in a period of weeks or possibly as long as a few years, but fail, it will. Since the energy delivered by your CDI outperforms the standard Bosch CDI, there will be no exception to this for your product. In addition, 5 kohms extra resistance will significantly reduce ignition energy, so why keep it?
Frederick C Winterburn the energy delivered by our CDI+ is the same as the Bosch CDI, except we fire the coil twice which is what gives the extra performance. Other CDI systems may roast resistors and coils if the output voltage is too high or the storage capacitors are larger.
Off topic, but what color is that car?
"Delphi Green" - its a 914 color.
It is Delphi Green as Grant says. A superb colour!
