F430 Challenge Headers

Random question as I become more edjumicated (and apologies if it's covered previously, just point me to where and i'll stfu ), OBD-based emissions testing.....should one obtain a tune from, say, Trev, presumably this will still pass the plug test? No sniffers, just assume non-catted headers and (possibly) a high-flow setup from the glorious aftermarket world.

The tune doesn't just leave them in a constant not-ready state, does it? It corrects for the change and makes it kosher?

 

Ask the tune maker. Non-ready will fail CA smog.

 

Here is a question. Are these challenge headers using the same thickness as MKII cats or MKI? I would hope if they were manufactured after 2008 they would use the stronger design and that all Ferrari did was not install the cats during assembly of the headers.

Contact Aldous at AV Engineering for any CELs such as air injection, secondary air, cat efficiency, cat monitors, secondary o2s, readiness, immobilizer delete, gated conversion, evap system removal, etc. They have all the necessary experience and tools to fix this properly.

Many of the "coded out" aftermarket examples are quite scary. They are done completely wrong in a very hacked/botched way, the number of Ferrari's I've had to fix lately with botched mapping is unbelievable and quite sickening if you love the cars as I do.

Many are not doing it in the proper way that Bosch would have done it. For example I've seen some tuners are simply hiding of the ecu light so you don't "see" the CEL, this is absolutely NOT the correct way to do it properly as the ecu software still sees the faults and acts accordingly as if the fault was there because it still is. By not properly deleting the components you can get into a whole heap of engine troubles longer term.

If you just hide faults to remove components like air injection the underlying fault condition still exists which can lead to all kinds of unintended consequences and it can be bad for performance, throttle response and drivability, in the longer term too much fuel being injected for example on startup due to coding out air injection wrongly could lead to bore wash issues!

O2 extenders are very hit and miss, I wouldn't recommend them as they are not a forever solution and can trigger a CEL under all kinds of situations such as cold starts, etc. Getting the software reprogrammed correctly is the only way to remove things properly.

there is of course a difference between just O2 extenders and O2 extenders with mini cats. Redback seem to be the best available http://www.redbackconverters.com/part-cat-mini/ available on ebay https://www.ebay.com/itm/Redback-Fault-Correction-Mini-Catalytic-Converter-M18x1-5-Thread-/141167242976

 

Thanks for the lead!

 

Mine should hopefully arrive tomorrow

 

Nice!

 

Wonder how these will sound with tubi 200 cats and 430 sport exhaust- that will be my setup ok my 07

 

Image Unavailable, Please Login Image Unavailable, Please Login so mine did indeed arrive today, apart from the O2 Sensor what are the other 2 bungs for please ?

 

Big one is O2 of course. The other 2 on my challenge headers are capped off as they were on my (euro spec car) old stock 430 headers. Small one I think is for a thermocouple that my car didn't have.

 

ok thks looks like I need some caps then

 

Early F430s still used thermocouples, later specs eliminate them entirely for temperature estimation modelling which is more than sufficient for cat monitoring

https://aldousvoice.com/2014/03/25/ferrari-f430-exhaust-manifold-change/ yes I see that, any idea what year they changed Trev ?

 

Mine is '07 without them. So maybe the '05, '06 cars had them?

 

My 08 doesnt have them either, seems as the middle sized bung is M12

 

eurospares sent me an email saying the parts are still on order...fingers crossed

 

After reading all the O2 woes I decided to cancel mine since I am in CA.

 

the left one is ready to ship but theyre (eurospares) still waiting on my right one

 

Communication from eurospares has been excellent

 

I love those guys!!
