having some issuse after upgrades

Post by speedemon »

ok i installed t2871 turbo, 740cc injectors, 264 cams, z32 maf
i got the car to start but its running very rough and unless i keep my foot on the gas it will not stay running so i can't even see if the timing is right
i marked the cam senor so it should be close
its almost acting like its running on 3 cly's but im not seeing any misfire codes
is there anything in nistune i need to be looking for?
i did make sure that the injectors and maf were setup
thanks in advance

Were all the modifications done at the same time? It is best say to do the MAF and injectors first and then adjust those and check, then afterwards do the cam and turbo, that way if there is a problem its found at the problematic modification step

Does it show Z32 MAF when you go Operations > Resize MAF still? Have you tweaked the injection multiplier further to get better AFRs at idle?

ok i looked a the maf and its showing the right one
now with the inj & maf set i have a k of 18480 but doing the math from the manual i should have a k of 20411
i have it idling better but it smells rich and for some reason my W/B is eather showing 7.4 or 21.9 its not tracking like it should

Wideband sensor may need recalibrating if its jumping all over the place. Refer to your manual, but it will require open air recalibration

After that put injection multiplier on auto and use +/- to adjust to get your AFRs at idle around the 14s
