F430 cel wifi diagnostic dongle

Most (if not all) OBDII code readers are capable of clearing codes. But, codes arise for a reason, clearing them does not resolve the root cause and without that, they will come back

 

Clearing a code is only the first step in troubleshooting and should not have any negative effect on the ECU. The code will come back if there is an issue. However, I have seen in some cases where the cheaper generic readers will blow fuses which leads me to believe that their quality standards may not be up to par to work on a $100k+ car. Just had to work on a Jaguar XKR after one of those dumbass insurance thingies screwed up his OBD system.

You have a Ferrari, buy a real reader from a company that has been proven to use modern quality standards in their manufacturing process.

 

I've been using the same dongle for years. It's fine and yes, you'll most likely get a CEL with headers. O2 extenders didn't work for me, so I just clear mine whenever it decides to pop up.

 

I'm not sure if they can tune that out or if they simply turn that light off permanently.

 

In ref to getting a cel on changing the manifolds- i fitted the Capristo version on mine, i get the occasional code but just turning off the battery will clear it.
As you will be fitting a manifold with no pre cat, it has a tendency to throw a code if you do not give it enough time to warm up the exhaust system, i found that if you let it tick over without touching the throttle i have no problems with codes- my opinion is that it allows the sensors to heat up enough so that any unburnt fuel lands on a hot sensor and burns off, reving it while not hot deposits fuel on a cool sensor and triggers the cel. I have had 1 cel last year re exhaust.

 

I get a cel everytime I take mine out. AP Headers, Sline Exhaust w/ 90 degree o2 extenders.

 

You can fit miniature catalytic converters like these (http://www.bigdaddiesgarage.com/) to the downstream lambdas to eliminate any cat efficiency codes. If you're struggling to find a UK supplier give me a shout.

 

I'm running Fabspeed Headers with 90 degree O2 spacers with mini catalytic converters (also from Fabspeed). So far so good, after 2 months no CEL.

 

I swapped to AP headers then just under a hundred miles started getting P2197 codes. Clearing them resulted in no CEL for 2 weeks before it came back again. I started getting P2198 codes and at that point guessed that the front left o2 sensor had gone bad since it was reporting both lean and rich fuel mixes. After replacing the sensor I never got the code again.

I used a cheap 6 quid Autel OBD scanner

 

These simple OBDII tools work fine.

The oem scanners are far to expensive to buy.
