My preference is aways to do steady state mapping on the dyno then refine the transient calibration on the road. Unless your engine is det limited everywhere I dont see how you can calibrate ignition (well anyway)

I agree with Stav that knock control is not neccassary, I have run without it for 4 years on my race car (205 sr20det & self mapped MI16) in temperatures from -5 into the 25-30's. Its just calibrated well the Rb30 Sc will also run without it.

If you understood what was neccassary to calibrate knock control to work well on a production car you would realise its a waste of time on a race/ high performance car. Half the time it will be taking out ignition when there no knock because the systems are so basic.

It doesnt explain how it works though, i.e does it compensate fuelling by actually cutting the standard injector pulse and replacing it with one its calculated or does it frick about with the AFM signal. Then add an offset frig map for ignition

If it works by cutting the ingition and injection signals and replacing them with absolute values from its maps, as well as the AFM frig map it looks like it could work well.

Who going to map it Stav? Or are you going to give it a go yourself?

Stavros · 12-05-2008, 10:32

Dunno who is gonna map it mate, Stu@MD is about the only person I trust tho.

Not much updates lately, I nearly sold the engine as needed some money for something, but couldnt bring myself to do it, cant face not driving the car for a bit.

Ive decided the brakes suck, not mega vital for drifting, but they do suck.

Not sure what the crack is with getting bigger ones tho? I think I have Skyline disks and calipers, but not 100% if the disks are, and as they must have some kind of adapter bracket for the calipers, is it aftermarket Skyline big brake setup I need, or?

RB26s are totally torqueless too, gay as frick. Powerful at the top end, but lame on these stock twins, and expect the cams make it worse.

Cant wait to get the single on there.

Karan · 12-05-2008, 10:41

nice remap should help a fair bit on low down power.... our rb26 was flat as hell on n1 turboes before remap but when it was mapped it is now much better...still fairly shite though

Stavros · 12-05-2008, 10:54

yeah its gay, boosts early, accelerates and comes on boost evenr really low down, but still not powerful until 5k+ really, and need to give it 7.5k everywhere to properly have it.

deffo got cams at least, as most stock 26s feel like they peak at least 1k lower.

Stavros · 13-05-2008, 16:12

Today as its a nice day ive mostly been showing my distain for the shit city of Bath by doing massive smokey burnouts...
