trying to narrow down the issue by eliminating anything that could cause it . I think it is due to having blow off valve so AFM is accounting for air that is getting released hence running rich and missing every now and then. does this make sense to you guys ?

You guys in AU are lucky with so many skylines i didn’t know there is even an option of fitting r35 afm, will look it up

Askd few times as i suspected he meant the z32 afm but he said the software and z32 hence why i am asking anyway, how are you finding nistune? Would you have invested in link g4? it has quite few features but not sure if i would ever use it does nistune provide an option of protecting engine from blowing up by reducing boost or limit rev if hot? i think something like link does

i fitted a nissan micra 1.3 1998 after cutting wires, seems to work and show reading . i have a mis fire even before changing the o2 so not sure if it is the o2 sensor my understanding is they have a range so it shouldn't really matter

All, My r34 had an engine light on and it seemed the o2 sensor was dead as there was no input on my apexi turbo timer on A/F. in the uk the cost of O2 sensor was around £150 so after long search of forums, I ended up buying one for nissan micra 1.3 1998 and fitted after changing the wiring on the O2 sensor so it could connected to the ecu connector. here is another example of it in the uk confirming the o2 sensor works on Micra as well as Skyline https://www.ebay.co.uk/itm/OXYGEN-OXY-O2-SENSOR-for-NISSAN-SKYLINE-R33-RB25-SERIES-1-Series-2-RB25DET-/301405627170 The car was ok but still felt as it was running rich so I changed the turbo boost pressure sensor and still seems to be mis firing . The Boost pressure sensor item number was PS660-1 Hitachi boost sensor which match nissan navara 2.5 td 2002-2005. It costs £80 from a distributer in the UK if bought for skyline so i bought it for nissan navara 2.5 td 2002 and it was half the price and exact same part number. question is, if the part number is the same, should it produce a same output regardless of car it was on ? Could I have messed up by installed an O2 sensor from another car? I suppose the reading will be the same so it shouldn't matter.

hi all, Skyline has been off road for a long time and now driving it . oil was changed around 14 month ago and since done only 300 miles, should I change it ? I normally change every year or 600 miles spark plug has done 1.5k and it is been on the car for 2 years

sorry to re open this old thread but my question is related. I have been calling supplier and have been told nistune is limited to 480bhp by one, is that true? my car is r34 gtt

All, I have changed my brakes to evo 9 and rebuild the rear . front disc and pad is brand new with red stuff ebc rear disc is used with new red stuff pads i have spent so much time bleeding the car but the pedal is still spongy which i guess you get when you have new pads in . this should go away with bed in but my car brake pedal sponginess is excesssive i think it is the pump that needs bleeding for which I need abs module circulation i bought datascan 1 but it doesn't do abs any software out there that does?
