93 Dx with 91 Si motor.. chip it or not to..
ok i have a friend that has 93 DX coupe we just put in a 91 d16a6 motor.
the original is the d15.
every thing went well motor runs well
but what about the extra displacment.
the 100cc's plus
i current under the idea that the motor may run slightly lean. (becuase of the intake and the headers)
i can't remember what ECU was in the car.
it was the D15b7 MPFI
i don't remember what it was
he asked about it and i completely forgot about it.
(Im such a terrible friend)
so im asking
any ideas

Chip the PO6, set rev limiter at 7500 rpm........
1600-3200 +4 degrees timing/-2% fuel at 10 in/mg or more
3200+ rpm +2 degrees timing/+2% fuel at below 10 in/mg
That is the basic tune I'm running on my D15B7 with ported head/intake/TB and A6 cam 1/2 tooth retarded.
Putting about 125 whp down, maybe a little more.
