Help needed on my K11 CG13DE : too less power, and stall sometimes
After the ideas of doing a remap/nistune, I first wanted the car to run okay with the standard ecu. Unfortunately I must say I'm realy NOT impressed about the power my engine produces right now.
There is a bridge over the highway, where I can time the car. It's a few kilometers from stand. With the original engine I could get the car at 170km/h at this point. I must say with the 773 cams, Janspeed manifold, bigger airbox and bigger exhaustpipes (not TOO big though!) I realy feld the car running faster! Perhaps this is because there is a bit more noise:suspect:
Yesterday I took this timingpoint and I only got to 155 km/h:down:
I must say to be a bit unhappy with this fact. How is it possible to be slower than an original CG13DE, after installing all this stuff?
The last few wheeks the engine starts to stall sometimes (its a 2000 type K11). In the 1st 2nd en 3rd gear when I go FT, the car goes fine, also reading 13:1 on my Innovate wideband. When I go to the 4th and 5th gear also FT, the a/f goes completely out of range to the lean side. Not always, but most of the times.
Also when cruising 80 km/h, and keeping this speed without pushing the throttle more, the engine sometimes stalls...... This is dangerous and very irritating also! At that point I go back one gear and give some more throttle. At this time the car shakes like a vibrator, than you feel the power coming back.
I thougt this was a ignition-problem, so I changed the rotor, distributor, ignitioncables and put some Denso Iridium plugs in.
Unfortunately the problem wasn't solved.
I took off the airbox and there where a little lose dirtparts lying on the mazes of the throttle body. A took them off, and went to bed.
Next day the car ran nice! No shocks, just fine!
Could if be this simple I thought?? But yesterday the stalling came back.....and there was nothing lying on the Throttle Body.
I must say when I did the speed timing yesterday the engine ran fine, also reading a/f between 12,7 to 14:1 So I can't say the problem I discribed above has anything to do with the fact my car has less power with this modified engine than an original car has.
I'm sorry to give these long lists of problems, but I must say I realy am down about the fact my original car runs faster than this modified engine!!
*I remember one more mod I did: I places a cheap feul pressure regulator....but to be safe, I placed if AFTER the original one, so the pressure inside the fuelrail can never get to low. This fpr is placed right in front of my steeringwheel (on the engine side), and when the radio is off I can hear this fpr making noise. It sounds like air getting lose, but that's not possible because I did leave the vacuumhose on the original fpr. It must be the fuel I hear running through this thing. The gauge says 2,7 bar. Can this deviece have anything to do with the stalling problem or little power? I doubt it.
