Technically correct, thanks.

How many people would know what afterfire is though? :happy:

personally I like a good backfire on a gearchange or decel but " hey" thats just me :yes:

If you find it a problem there are a couple of things you can change on your PFC settings to remove or lessen the effect.

Firstly your accel pump settings are set quite high from factory with the PFC. So any slight blip on the throttle pumps in a fuel but little air. This hits the hot exhaust with the usual pop pop crack sound. You can even "make" it do it on a trailing throttle by tapping the throttle lightly on decel.

Dropping these accel back from the 4 or 5 ms factory down to 2 or 3ms improves things.

Secondly the bottom fuel row settings have a big effect on trailing throttle overrun and can by reduced (carefully) to reduce exhaust popping. The PFC does have fuel cut on overrun I know but these bottom row settings do have an effect.

Cheers,

Mike

    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car

    • I believe @Duncan has given it a crack at Mt Buller before (in actual race conditions)
    • All my Polish car culture insight comes from watching Nightride. So I half expect this to get 1UZ swapped eventually?! Are you going to drive it in winter? I'm always curious how ATTESA would hold up in the snow. There isn't that much opportunity to try it in Australia.  
    • My steering lock unit on my Infiniti G37 has failed. The car is a local 2012 Infiniti G37 (Q60 ) I need to replace the unit My local mechanic said i need to buy a complete steering wheel assembly. Does anybody no any mechanics in Gold Coast or Brisbane who can fix this issue or where i can buy just the Steering lock control unit. Thanks
