Jonny Retrofit

It will go out this week.

Basically, I am 'dialing in' the advance so that what is on screen matches the actual timing shown on the strobe lamp.

Hi Lennie, We reviewed the DIAG logs you sent in. They show that the engine is not started ( 'WaitForStart'). The engine must be running for the A/C system to run. We also note that your battery voltage is extremely low - less than 8V.

Most likely ok. Believe it or not, scroll compressors are not inherently balanced so can be a little 'wobbly' until they get up to speed. Sounds ok to me.

That will 100% be the issue. Fit a standard Bosch CDI coil. We will return the unit to you.

Check the bulb wattage rating. If you are blowing a 7.5A fuse then either each of your bulbs is greater than 100W (7.5A x 13V = 97.5 Watts) or there is another issue ( like bad contacts/wiring in the bulb connector). If they are 100W bulbs then you might need to go to 15A fuses since the 7.5 would be marginal as calculated above. 15A should be ok since the standard Porsche headlamp wiring is 1.5mm2 wire which is good for 20A so the fuse will blow before the wire melts! The H terminal can be used to provide another ‘way in’ to the fuse panel from the battery so the current is not all carried down the single factory thick red wire (which is good for about 40A). Fit a 2.0mm2 or similar red wire between H and the battery + if you really do run 100W bulbs to spread the load.

Ed, we received the unit back but cannot find a fault with it. It tests fine on our test bench. Also, note the OP is saying that his Bosch CDI might be faulty, not ours!

Thanks for the comments. Correct, the white lines indicate an internal bridge on our panel effectively replicating the copper bridge. Wire not needed on SC.

Sorry for late reply. A bit of illness, Easter break and moving premises left this thread wanting! Here is the cable drawing for the switch loom. CLAS01-DWG015-REV01.pdf The ECU needs 12V on the black/white wire to switch AC on. 12v is provided on the red wire. If the ECU button mode is set to Momentary, then a pulse is expected. If the ECU button mode is set to Latch then a high level is expected. You can change this in ECU by typing BUT=0 or BUT=1. Use LIST to verify changes. The Brown/Yellow wire is the LED lamp wire. It is a 12V PWM drive to control the dimming. Do not use a conventional bulb. The black wire provides the ground for the LED.

No, not drilled through, the screw is positioned to stop the weight from moving.

On your Carrera original block, all 3 fuses are linked by a brass strip on the back. On our fuse panel, only two of the fuses are linked as indicated by the white stripes on the front side. You need to link the bottom two fuses ( in your picture you have linked the top two) so move the link down.

Hi Rob, the 3.2 Carrera fog light mod is covered in the install manual in Appendix F. https://www.classicretrofit.com/pages/manuals-and-software

We have just added a fittings pack to the website for the Porsche ‘belly pan’ condenser. The hose for second condensers is #6. https://www.classicretrofit.com/collections/electric-air-conditioning/products/porsche-911-belly-pan-condenser-fittings

Yes, correct. The unit as shipped is plug and play compatible with the Bosch unit.

That sounds like a typical early fuel injection issue. I would research how to setup / check the CIS.
