575M Check Engine after service and exhaust

I run the same setup in my 575. You likely need o2 spacers or a ECU tune from Trev.

 

PS the suspension errors are likely from a bad battery or being unhooked for a while. A fresh/fully charged battery and a few drive cycles should fix that entirely. The 575 Sachs suspension while not bulletproof is far more robust than the Bilstein on the 550/456 (not just repeating rumors, its well known and I have (unfortunately) direct experience as I also have a 456m).

PS you can test yourself if the flow issue is the cause of your CEL after your other errors clear/settle down and fresh gas (this is exactly what I did).

Light (<50% throttle, <4500 RPM) driving with all lights cleared should be uneventful. Your idle should settle quickly with fresh gas/drives cycles (exactly what happened with mine)

Then hard throttle and high RPMs on a warm engine (remember you have secondary air) with valves open would trigger a CEL until I got Trev's remap. Trev's remap fixed that (again after a few drive cycles), and further will boost your HP by a 100 or so while giving you 599 level smoothness of the F1 system. The cheaper/faster solution is to get O2 spacers as to slow down the flow.

Feel free to shoot me a PM if you want to chat.

 

Lambda refers to the air/fuel ratio the ECU is seeing. On my Toyota, I run a wide band O2 gauge and run it in Lambda mode, as opposed to air/fuel ratio for gasoline.

I second getting a tune. If the idle is unstable, most likely you're running a bit lean.

There have been a few niggling CELs with Fabio's headers. A Trev reflash, which Fabio himself will likely recommend, should clear them up as well as unleash a few lost horses. If interested, he can speed up and smooth your F1 shifting, too.

 

I ran that way for about 100 miles. Doesn’t seem to have hurt anything but YMMY

 

I did my own intake gaskets (while changing all of the coolant lines under the manifold). It's not that scary, just tedious and guaranteed to make your back ache! I'd be glad to help you with yours if you ever need to do them.

 

That procedure should not have set an airbag light. That usually only happens when someone jump-starts a late model Ferrari. You will need a high end diagnostic tool like an SD2 to reset the airbag lamp.

 

Agreed. Hopefully in jumping you didnt fry an airbag ECU. I know thats a common issue with jumped 550s and 456s; I also heard it happening with a 575 but that is hearsay I dont know the details
