Last night I tried upgrading firmware to version 1.2.23 but vems was having none of it and complained about not having a vems.hex file. So looks like I need to sort the bootloader out. I checked the post and the cable has came to do the upgrade so I will try it this weekend.
After that I messed with some boost pid settings and advanced the timing slightly and had a drive. Timing is still very safe and I could hear no ping with my diy det cans. Well boost is now were I want it and the car is starting to get ridiculous! It actually slipped the clutch a few times but then seemed to settle in. Hopefully it's still just running in. Power builds strongly after 2k rpm and by 3 k it's nuts. It holds the power to about 6.7 k when I can feel it start to fall off slightly but in all fairness it's pulls hard to 7.3k limiter.
My next problem is that the lpg ecu logged the petrol injectors duty cycle at 100%. This means the gas ecu thinks there is a fault (as who runs injectors at 100 %) and puts you back on petrol. I used about 1/4 tank of petrol in 25 miles.... The injectors are 630cc and I'm running a 3 bar fpr. So I will refit the 4 bar fpr and rescale vems and the gas ecu. In all fairness I am a bit rich at 0.74 lambda so the combination of leaning that off and going to 4 bar fpr will get me enough fuel to keep the duty cycle sensible and the lpg ecu and my wallet happy.
The car has spax adjustable suspension with all new bushes and solid subframe mounts last year so drives nice but this engine is way too much for the chassis on a county road! I have the dampers softened up to make the car quite comfortable to drive but I'm going to have to stiffen them up somewhat. That or take it easy over bumps. The way it puts it's *** into the ground and it's nose in the air under acceleration over bumps etc is a bit scary. I suppose I could lift off.... In all fairness I have brought the boost back down slightly as honestly it is just to hairy on my test road.
Cheers des.
