Er34 Nismo Injector Help, Latency Numbers And Part Number

[Jayden.K]

i bought my gtt a while ago i have not known what exact injectors i have. i fitted a 3076r and type b cams, using a power fc. and when we went to tune i didnt no what injectors i have, but by already set numbers we assume they where 480cc, they were purple and said nismo on the side so we confirmed that. BUT. when researching the latency specs we cannot find anything at all. the injector on the side has a number 013 4608 we shows nothing when researching, now this car had work done at least 6 years ago including these injectors from what i know. Is it possible these are a old nismo injector that i cant find any information on. just need to know what this number represents, that there 480cc and what the latency times are. please help!!

thanks

if you got some spare cash id say just get new injectors and a new tune, that way you know exactly whats up

The tuner will be able to work out the latency wen he is tuning

Yeah he had some numbers but the car ran like shit when he set them in. Turns out he may have been right this whole time with the lag times because my maf is f**ked. So once I get the new one in it should all work out. Thanks anyway

I think what Jez meant by "The tuner will be able to work out the latency wen he is tuning" is that if the tuner knows what he is doing he will be able to work out what latency is correct by the way the car reponds when it is being tuned. What you do (with Nistune) is set the K value to give you the correct mixture when at moderately high loads (so that the latency is not significant) then, knowing that the K value is correct you go back to the light load/idle part of the map and fiddle the latency until you get the right mixtures there. Little details about setting the cells to zero and turning off O2 feedback have been left out of the above description. Whilst PowerFC and Nistune are not the same same, the process is similar.
