So I have been running the new DP Chip-X for the last few weeks in my 2005 Hilux D4D. It has been amazing. The car feels like a new car, a much much faster new car. It no longer just plugs into the front of the engine. It is like the Steinbauer chips and piggybacks onto each injector.
Last weekend driving from Melbourne to Adelaide my car started going into limp mode. After driving for a few hours at 110kms the car was going fine, no issues. That was until I had to slow down to 60 to cross a crossroad. Once I had crossed the road and was accelerating back up to 110, the car went into limp mode with an engine light up. I turned the car off and back on and there was no engine light. It continued to drive all sweet until I needed to slow down and speed up leaving a town and boom, limp mode. It was not happening every time I slowed down, but more like every 4 times (30-60 mins apart).
I disconnected the chip and ran the rest of the trip without it and no more limp mode. 1800kms later when I got back to Melbourne I went to a mechanic that had a M-ODB reader (why can't I just buy one?) I was able to see 2 faults. p0200 injector circuit (fixed) and p1251 stepper motor. Now the injectors are only 2000kms old and I don't have an upgraded exhaust.
I am guessing it may be the chip. I really love this new chip. It is amazing and really don't want to give it up. Has anyone else had these issues? Is there a fix?
The experts tell me it may be my stepper motor failing. The guys from DP have been really good and have offered to ease off the curve on the tuning so the power comes on a little slower. I am just seeing what others have experienced or think.
I have a 3" domin8tor exhaust ready to go on soon with 200 cel cats.
