Hi Guys,

I have a J spec TT. When I bought the car it had fitted a Blitz induction kit upgraded chip (not sure what make that is) Dump valves again not sure what make but they came from America according to the recept and an Apexi AVCR.I came across this (see pics below)I thought at first that it was part of the Boost contoller but now pretty sure that it was fitted in Japan cos its the only Mod on the car that I have not got the recept to.The thing is still live cos the control knob lights up when the ignition is switched on but the control is set to zero.The question is what is it what does it do can it still be used in conjunction with the boost controller or is it redundant and needs to be removed ?

 

Would appreciate any advise Thanks.

Pretty sure that's the original APEXi SAFC, I had one before opting for a standalone system

yeah I agree - I think it allows you to adjust the airflow reading that the ECU receives and therefore the richness of the mix. The AVC-R is a boost controller which allows you to control how much boost you run. Do you have the AVC-R as well (i.e. a black or blue digital screen with some arrow buttons at the side - similar to the S-AFC2 in the link above)?

Hi yes I have the AVCR too a blue screen with arrows at the side.

cool - the AFC is something that should really only be tuned by a professional or someone with experience as getting the setting wrong could result in too lean a mixture (and detonation) or too rich a mixture (and poor running/borewash). I assume zero is a safe setting meaning no modification to the signal to the ECU, but I'm not a professional!
