engine..
sr20de-t
stock sr20det turbo setup
370cc injectors
n60 maf...
stock ka24de ecu w sr20de harness..
ok now when i was running the stock ecu it ran ok
a bit rich..... but it revved past 3500
i purchased a second hand nistune ecu..for a ka24de-t.
it runs fine idles perfect for a long time
but as soon as i rev it up it goes into limp mode and shoots a maf code
i switched maf in drop down window...still no luck
now i wasnt getting any maf codes w stock ecu
am i crazy or should i change maf..????

do you know what maf was used when the ecu was in the other vehicle?

might need to start from scratch with a base tune then change to new maf.

yes when i initially opened up nistune it was set for a n60 maxima maf...
it would sit and idle perfect then once id rev it up it would then go into a limp mode...
and shoot a maf code...
so id start over restart car and nistune...changed maf in drop menu...made sure the k constant was matching the k value from the sr20det maps..k 21475
and it would be done in then it would start goin into limp mode again
so i eventually had to put a sr20det maf...since both my ka24de maf is bad
and my n60 is getting codes from nistune ecu...
i switched maf in drop menu...now car runs better....
wideband stays pegged on rich..22.4
i attempted to move k value to get a change in reading but no go...so i left it at k21475
it also gurgles a bit past 4000 rpm like injectors hit 100% duty
and when i rev it i can tell its real rich but not like a bad cts rich...just a bit
i attached my tune...
if some one could take a look and lmk wat im doin wrong
