help ABS comes in too early

[Desey]

Hi all

 

Have a 04 JDM Z with non brembo brakes

 

when buying i thought the standard brakes would be good enough. turned out they sucked

 

changed to yellowstuff pads and slotted discs and the braking is now great, but the abs at times comes in way too early but i know theres way more brake force that could be applied

 

im running Rota GTR-D 18"s with 235/45 front and 255/45 rear and -1.5 camber on the rear

 

is there any way to adjust the abs without ecu mapping or whatever or disable the abs?

Surely the ABS kick-in point is determined by the ABS Sensors that are in the hubs and the ABS ECU? In which case changing the brakes, tyres, whatever, shouldn't have an adverse affect at all? As soon as the sensor detects some under-rotation of the wheel, it kicks in, regardless.

I'd have thought that short of modding the ABS Sensors / ECU, the only way to have a greater rate of deceleration before ABS kicks in is to have more grip? Better tyres, different pressures, etc?

I'm not sure but I think it's your tyre sizes that are causing it. I do a calculation online to check the rolling radius difference from oem
