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 falkhen |

engine will be fine, the slightly rich B7 tune will be perfect of the A6.

wheres the rev limiter though ??? that would be my concern if it was lower than the pm6 rev limiter that would suck.....it wont run lean and cause any damage though

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. |
