The Racecar Needs Your Help! Options

[turbohcar]

I have been having trouble with this beast for almost a year now and no result has come of it. My friend and I have built a Hornet/Wild Thing racecar for the dirt circle. It's a 91 N/A (turbos and AWD aren't allowed) 5spd 2.0 4G63. Now, we bought it from some hillbillys in Ohio that had a Mitsubishi graveyard. The car came in stock condition minus an ECU. We thought, throw a good ECU in and we're good to go.....Wrong! After two ECUs, eight spark plugs, four plug wires, two coil packs, two transistors, two CASensors, two MAFs, four injectors, a fuel filter, a battery, a fuel pressure regulator, and misc. other things this thing still doesn't run correctly.

Finally, it's warm enough to do some work and Spy graciously let me borrow his logger to finally get this thing figured out. Here's the log I came up with. All of these are done with the gas to the floor. It cuts out around 5k RPM and acts like fuel cut. Sometimes it does this when climbing in RPM too but really only cuts out at 5k (on the stock tach).


RPM 4343
INJP 11.77ms
KNCK 0 (I don't think the N/As have a knock sensor)
TPS 99.6%
INJD 42.1%
TIMA 21*
02F 2.48V
COOL 85.6*C
AIRT 28.6*C
EGRT -28.2*C
BATT 13.0V
ISC 23.4%
MAFS 855.4Hz
ACLE 0%
02R 0.66V

Here's another

RPM 3312
INJP 11.26ms
KNCK 0
TPS 99.6%
INJD 30.4
TIMA 22*
02F 2.48V
COOL 87.5*C
AIRT 30.0*C
EGRT -28.2*C
BATT 13.2V
ISC 23.4%
MAFS 610.1Hz
ACLE 0%
02R 0.78V

Please help. If you've got any ideas let me know. I did notice that injector duty is incredibly low and don't know how to explain it. Thanks for any help tuners.
