hi all, as you probably all know i bought a new computer setup for the micra. my question is that the throttle body i got with this setup does not have an afm like the standard micra throttle body. does this setup look like it bypasses this? any help would be greatly appreciated.

it doesn't have a maf?

all i can suggest is plugging it all in, and trying it, i am currently working on a mafless ecu setup, i could imagine nismo already have it sussed.

if not contact the seller and ask what maf should be used, if it is mafless, by the nature of the changes made, you may find problems when driving on the street under normal conditions, and i would also get the a/f ratios checked

Yep failing that it is possible Nismo programmed into the comptuer to read the signals from another AFM - most likely an SR20DE/T or even GTiR SR20DET AFM. Mabye even something larger like a Z32 300ZX VG30DE/TT afm.

Those are the most common used with modifying 4cyl nissan motors anyway!

I think he bought it through auctions, it was probably just pulled out of a wrecked racing k11 by someone, sold on yahoo to gtrholic's friend in japan and then sent to him here in australia.

I think the chances of getting a good answer would be rather slim - but thats just me being pessimistic!! :p

hi all, yes it is a complete rewire. the harness is included. the computer looks different to that of a normal micra. dont know what the go is there. sorry micrapete, i really dont want to pull the ecu apart cos it has the "void if removed" nismo stickers still intact. its just for the purpose that if i wish to move it on later, i can guarantee its authenticity. ill try and take more pics. it seems to have wires hanging off here and there which i have no idea as to what they are for!

no need to pull the consult apart, if you had consult cables you get the ecu that way, i wouldn't want it dis-assemble the ecu either!!

btw the ecu is the later type japanese k11 type :)

this is a "nismo k11 N1 kit",but not included the tb body..
the tb comes from nissan p10 or p11(sr16/20).
if you want to use that,you have to find a afm from any sr16/20 engine , it's not only for N1 , anyone if you like,youcan swap your tb from sr20 !!

AWESOME PICS LEWIS! Where did you get those pics from? what is the diameter of the sr16/20 afms? they are the same right? do you know the diameter of the throttle body? i'll have to measure mine. do you know much about the injectors? my injectors look the same as the ones in your picture. the pink ones. i was only told there was 1500cc worth of injectors. im assuming that means 375cc each?

That makes a lot of sense lewis. hmmm... do you have any more pics of the n1 k11's? are the sr16 and sr20 afms calibrated the same? does the existing plugs, plug straight in? or does the wiring have to be modified?

sorry GTR, i've measured the sr20 tb inside dia. should be 60mm,not 70mm, but i remember there were 70mm tb , maybe sr20det or something....
the afm will need to be calibrate if u want use it on cg13 ecu, but not too much different, it's all 5v signal !!
ofcourse if u can post some pics and i'll do my best !!

hi lewis and all, the setup is at my friends place at the moment, ill bring it home and take some more detailed pics. but from what i can remember, it looks like the throttle body on the bottom (throttle body pic) it has a triangular shape.

can you get any numbers / info from it you can, the issue may be the maf may be a completely different one from the throttle body, have you tried it without a maf? is there any odd bits of wiring loom?

Crazy, the dizzy needs a spark generator (has 5 HT plugs), looks like its not done within the dizzy, perhaps its an old rotor type thing, wonder what their reasoning is for doing it like that? Looks like you have the generator tho!

Does the dizzy plug into the loom?

I wonder how big those injectors are!

Hope you get it all working.
