F355 scan tool non OBDII

Most OBD-II readers work just fine on the EOBD system, presuming your car has an OBD connector under the dash. If not, you'll need to connect directly to the ALDL connector at the Motronic unit with the factory diagnostic tool (SD-2).

 

You'll need the factory diagnostic computer then.... However, I'd double check under the dash. The diagnostic connector can be a bit difficult to see.

 

I have suscesfully used a generic reader on my euro 355 5.2.

No need for the sd computer.

 

not true,

you need an adapter cable for the three pin connector close to the ECU and then any OBD code reader works

 

Learn something new everyday...I can't say I've ever run across the need. But Google did show me what you're referring to. I guess owning the factory tools makes live easier...no adapters, generic tools, etc. Just plug and play. Thanks.

 

If there were a **** ton of sd tools out there id have one.

But they are not and cost upwards of $20,000

The aftermarket leonardo is $17,000

If they made a simple version like they talked about for just a few cars it would be great, like id get bwhind something like.that say for 355 only or maybe a few cars worth of software. As I wouldnt need software for every car.

 

Johnny, Speak with Nick. Leonardo does have a single model tool. I've been email with him about it. Not sure when, but I will likely get it down the road.

 

I talked to Nick last year about a single model Leonardo. It is available and you can swap it for a different one should you sell / buy a different Ferrari.

My research at the time suggested that the Leonardo was good....but not great and lacked some of the functionality that the SD2 had.

Perhaps things have changed.

 

My understanding is it's a good tool. For the price point it seems like a reasonable deal for some who likes to do their own work.

 

Looks like there is no middle ground between a very expensive tool and a home made solution, connecting the diagnostic connector behind the seat to a universal scanner by connecting the 3 wires.
And as far as I have understood it, not all universal readers/scanners work on the 5.2.
With all the knowledge there is over here, there must be a possibility for someone to develop a mini-SD.
I know that someone on the Maserati board in the Netherlands was busy developing a mini-SD for the maserati 3200, but he stopped with developing further after selling the car.
The mini-sd was put on the market at very smal numbers, maybe only just a handfull.
So not really available to the public, and being for a maserati most likely not plug and play for the 355.

But as there were initiatives in that direction, surely a silicon valley inhabitant with some spare time and a sense of business can see an opportunity here.
I am sure he would sell hundreds of these things to us worldwide...

 

A scan tool can be made but the problem is probably some licensing issue I would speculate. There is a unit made for Porsche called Durametric that is the equivalent to the factory tool and it is fantastic. I recently broke down and bought the full on professional unit (I'm a tool junkie) and it was approx. $700 which allows me to do not only OBD II, it does OBD I as well. It is really neat to be able to do custom data logs which you can download and print out as charts for tuning as well as routine service items (like turn off the airbag light on my 964). I haven't even scratched the surface with this thing yet. I'm an old school guy having worked on carbs and setting points as a kid and it is really neat to now be sitting in my 996tt tuning with my laptop. Someone can do it, just hope they step forward to do a Ferrari unit for us DIYers.

 

That would be correct, although many in the professional community might question just how good is with regards to pre-360 diagnostic capabilities. Regardless... even with the factory tools, there can be limitations. The SD-1 had full functionality on the F355. The SD-2 lost some functionality on the F355 with regards to the top and setting the seat potentiometers, but otherwise is identical. The challenge for any tool, other than factory, is that (most) ECU communications (other than the engine) is NOT done through the OBD-II port, but rather via individual ALDL links. This can pose certain challenges for aftermarket tools.

 

In discussing the Leonardo with Nick, the system has the functionality needed for the 355. He has advised me that updates come monthly and he has no insight on any limitations.

That said, if someone would like to point out these alleged limitations, he will gladly review them. The developers have the factory tools to compare functions to their offerings.

 

Well, hopefully they fixed it since last year. I'll save the dealership name that had my car, but the Leonardo they had could not bleed the F1 system. Continental did it with an SD2 in an hour.

Can it read the spider top codes?

Group buy?

 

I'll speak with the factory techs I know using the tool and see what they say regarding the 355.

No idea on spider functions as I never intent to own one so you will have to check that yourself

Group buy? That would be cool

 

For those interested, I did speak with a Leonardo user (also owns an SD2) today who has had no issues using the tool for 355's and 355's F1's. I have others to talk to as well and will do soon.

 

The 355 gearbox software works on the Leonardo, It was one of the first items ever done by Accinni. What has probably happened is this..

The Leonardo due to its blue tooth interface requires a min of 12.5 volts for the interface to communicate to the car. We recommend that all cars attached to a Leonardo to have an external 12 volt battery pack installed the same as any BMW or Mercedes. Many workshops still do not use external battery packs/ tenders/ chargers when working on the F1 gearbox. While an SD2 will still work at 12 volts as its a hard wire from tool to OBD or ISO

There are many hundreds of of Leonardo's working in independent workshops and dealers ships. If anyone would like some workshop references that use this tool daily, just PM me and I will give you a list of owners that you can contact directly to ask them.

The Leonardo is the standard if the Industry for Ferrari & Maserati repair as we have full line coverage with technical support on how to repair the car and how to overcome the current situation that you are in.

We have coverage on all models from the 348 to the 488 at this time and even the La Ferrari.

We also offer 2 training courses per year one in January at Naples Motorsports and one in Las Vegas at Speedway Sports cars, Then next coarse is on Saturday November 5th a Speedway Sports cars at the Las Vegas Speedway. Fee is $500.00 for the one day.

Anyone having difficulty with a Leonardo should have training OR If it is a true hardware or software issue they should contact Accinni technical support at [email protected] or myself at [email protected] and we can address the problem

 

If I ever get my ass in gear and go with F1 car this will be the first thing I get

 

Yep after I made a harness to plug in my generic reader to the plug at the motronuc ecu I also ran power to the reader from the lighter.

Its ugly and done using wires from a cut harness I had.

If you want to.see it let me know.
I wish I had the spare cash at the moment for a leonardo id buy one in a heart beat.

 

It would be nice but thats a lot of coin to drop on only one cars software.

 

I have an OBD II, and it is not reading anything on my 1999 355 F1 Spider. I think the turn over year from I to II was 2000. Do you think this is why I cannot read any codes? I just get the "ERROR" message. Thanks
