I bought a simple FDTI chip based OBD II serial to USB lead. (see pics) Its very cheap off ebay.

The 360 Modena uses a Bosch ME7.3 (H4 Variant) firmware that's easy to pull off using 'boot mode' - assuming you can work out the pin out which was a bit of a pain. I had access to the workshop manuals so I traced the pins.

In total I found that 11 pins are needed to read and write the flash software from the Bosch Motronic ECU's found in the Ferrari 360 Modena, 360 Spider and also the
Challenge Stradale.

Here's my pinout that I used successfully;
  • obd-ii cable to pc. run software

(+) to +ve batt
(-) to -ve batt

(K) to k on ecu, directly wired <----> to pin F53
(L) not req.d - unused.


Power Requirements:
1. I used an adjustable Bench DC Power Supply set @ 13.5V (purchased from Maplin's)

These 4 pins must go to (ground) ;
(-) F10 Boot Mode earth [Shorted or Not]
(-) F24 Reference earth
(-) F25 Reference earth
(-) F49 Reference earth

These 5 pins must go to (positive) ;
(+) F15 Power supply +30 Power input
(+) F16 Power supply from main relay
(+) F32 Power supply from main relay
(+) F47 Power supply +15 Power input
(+) F48 Power supply from main relay

This 1 pin is the (Serial Programming K-Line) ;
(K) F53 Serial line K <-------- to USB OBDII cable --------->

This pin to the case of the ecu
(L) F20 Serial line L <-------- to ECU case Ground --------->


Looking at the ECU (out of the car) straight on, its the 49 pin ECU connector on the RHS (just above the white sticker) that your putting your pins onto.

See pics...

Forgot to mention, don't forget to upgrade BOTH ecu's.

That's right there are 2 on the 360,  left bank of 4 cylinders and right bank of 4 cylinders.
When dumped both ECU's dump identical rom firmware images.

FYI, in case you need one, here's the lead like the one I bought... Less than 10 quid from ebay.

And here's a better picture of the pinout required for your wiring harness.
