Sold Capristo OBD Wizard for 360, 430, 458, 488 for sale

$950 is pretty good for a used part, considering $1250 is new price.

 

Where would this plug in then?

 

How is this different from a $15 OBDII bluetooth dongle and a free code reader app? Just that there is a code clearing button so it takes 5s instead of 60s?

 

If it’s simply auto clearing the CEL, doesn’t this simply leave a car perpetually in the “not in ready” state when you go for an emissions inspection where they plug into the OBD port?

Correct. This tool is pointless. Just take some black tape and put it over the CEL and you effectively accomplish the same thing - the only function of this tool is to keep the CEL from popping up in the cluster. For someone who is not technically inclined, maybe that's worth the incredibly steep price tag.

The car is not going to go into limp mode from a lambda sensor DTC (improbable / implausible signal, no signal), which is the DTC you get from running catless. However, the car will permanently be running in open loop mode and the ECU will not be able to adapt to loads/temp/changes in air density in real time. It will use the standard open loop fueling tables and will run extremely rich.

This is always the case for running catless unless you have a tune telling the ECU to expect different (out of range for a standard car) values from the lambda sensors.

 

What happens to the ready state? Can you remove the OBD wizard and get your car inspected for emissions and pass or will it kick off the "not ready" state and fail?

 

Actually, you are completely wrong about that. The emissions testing guys have no clue what they are looking at and with the lower trays, their cameras see nothing. I have cats, but when I went to the NJ state emissions center the guy literally just asked me where the cats were? I could have said they were under a panel or something and he would have passed me as long as I didn't have a CEL light and the ready state was good. These guys now nothing about Ferrari's but as long as their computer says it's good to go, you get a sticker.

 

It is not - you clearly don't understand how ECUs/CANBus function and your responses here have made it readily apparent.

One or both rear O2/lambda sensors sending implausible values to the ECU will cause the ECU to run in open loop mode, not limp mode. If you are running catless without a tune, you are perpetually running in open loop mode. The vehicle is not able to adapt fueling and timing using the data from the rear lambda sensors, so you will run with very rich fueling and very little timing advance.

It is not possible to "compensate" for missing/implausible rear lambda data through the OBDII port. This tool is simply clearing any DTCs related to cat efficiency / implausible lambda sensor values as they occur.

That's not the "state" he is referring to. The ECU continuously monitors specific measuring blocks of data to determine if there is an issue with the engine/emissions system. When you take your car in for emissions and they plug their device into your OBDII port, it is looking for 2 things:

1. Any DTC codes that are emissions related
2. Full readiness across all emissions monitors

In order for the ECU to show full readiness, you must complete a full drive cycle without any DTCs or other issues (here is the one for the 360/575 - https://www.ferrarichat.com/forum/attachments/fbf25e33987f60d89c6e811eea8fcb6b-jpg.2936297/).

If you use this device to auto-clear emissions DTCs, the emissions monitors will continuously be in a "not ready" state. You can't unplug this device just before you get to the emissions place - you would have to complete a full drive cycle with the auto-clearing device removed. If you're running catless, you will get DTC codes during this drive cycle and will not be able to pass emissions.

 

This is the case IF it’s the front lambda/o2 sensors (pre-cats). Post cats does not work like this. Post cat is used purely to check catalytic efficiency. It can not alter fuel by definition because all the stuff that passed through cats are essentially filtered. And this filter varies by ages and acceptable until it is not which is detected by the post car and in return trigger the check engine light. This is why on race cars it doesn’t matter if you don’t run post car o2 or catalytic itself. It won’t alter how the engine operates. However if the lambda/02 pre-cat is altered, it will create problem. As you said the car will run in open loop and it will affect the health of the engine eventually. It is not advised to alter the pre-cat o2/lambda as the engine depends on this to operate correctly. This is also why the pre-cat lambda is a wideband and much more expensive than the post cat

 

That's actually not true for a stock car / stock tuning. The ECU does refer to post-cat lambda readings to finely adjust fuel trims and maintain closed loop. This was a feature starting with Motronic 7.X so 360 forward should incorporate this feature.

Either way, this product is just a sugar pill for those who don't want to see a CEL in their cluster.

 

I‘m not familiar with 360 but I was working with a tuner on F430 and that’s definitely the case. Post 02 is just for car monitoring
