So this is my problem, i did a mini me swap on my 92 dx (D15 Buttom) with a D16z6 vtec head the Rpm rev limit was around 5500 to 6000 and i didnt like it, so i bought a d16z6 buttom put it on, chiped the ecu (spoon) but guess what rev limit is now like 6200 rpm's and i know that im supposed to be around 7300 at least, Spoon is programmed for 8500 rev limit and vtec is kicking at 4800 and yes the vtec is working properly, i also try on a mugen chip but the rpm's are the same (6200)any ideas??? when i did the swap with the d15 buttom the valve lash i did was 7 mm intake 9 mm exhaust... Whats the valve lash on a D16Z6???

 

Short out your ecus main ground, you'll have NO rev limiter.

 

get rid of those chips b4 you dont have a motor

 

You need to do the 5-2 hack, you cruise at 80 mph in 5th gear, then downshift to 2nd. Guaranteed 9k+ rpm

 

ohhh yea i heard about that haha. just gotta show the ecu how high you wanna take it.

 

Guaranteed a piston broken to... no thanks but its funny tho

 

i bet your pistons will be great after. just not your bearings
