new injectors

fasthippo · Jan 23, 2009

i just put in some 30# injectors so i can actually go past 5k rpm now without leaning out (still need a tune to really drive it anyway)

but when i started it it ran like **** and threw a CEL. i think it was way rich.
is there something i have to re calibrate or adjust for the new injectors?
i pretty much just need it to make it to a tuner.

yes, the MAF needs to be recalibrated for the 30's, i just pick up a set of 24's, bucause I too was leaning out after 5k, and getting detonation...

yeah same here, luckily i caught it the first time it did it. started pingin by about 5.5k

is there any way to calibrate it without the tuner? the one i bought still hasnt come in yet....

i dont think so, i think the dyno tuner has to do it, but im not sure....

when mine gets past 5500 it almost hits a 14.0 AFR

lol ya i know i saw the dyno graph, did you make any more power up top once you fixed the fuel issue?

good job on makin good n/a npi #'s btw. how much of a pain was it to port the heads?

i havent been back yet, i had an apointment tommorrow, but my intake is leaking coolant, so i had to postpone it to next saterday

porting the heads was easy, it just VERY time consuming, i have atleast 25 hours in them, but i think it was worth it

You need a handheld tuner to calibrate it to the MAF
