I am tuning it at 6700ft here in Colorado Springs and I could only get 20.5 MP running at 6000 RPMs. It is running smooth, but I think it could be smoother. I will finish it with MODE 1. I had to set the Injector flow rate at 163. Just finished trying to adjusted the idle setting in MODE 2 and I am still having a difficult time getting the engine to smooth out at idle. While at 1800 rpms with cold start off, fuel pressure at 38psi I have to really lean it out to get it to run smoothly, it is at a setting that is too lean and the engine tries to quit. The O2 reading in just one bar on the scale. Then when I try to increase the mixture she get really really rough and occasionally will backfire. Then when I switch back to MODE 0 and place the cold start switch on she begins to purr nicely and she is very smoothly. I am a little stumped, I know when the cold start is turned on it doubles the fuel, but at idle with only the primaries firing if the cold start is turned on will it fire both the primary and secondaries or double the flow on just the primaries and not fire the secondaries? If I new the answer to this it would help diagnose the issue. I am also battling oil leaks. I have a few of the oil pan bolts leaking, I am going to have to pull then out and fill clean the oil out and then place them back in with pro seal. I tried with grey gasket maker, with no joy. I think i might have also have a leak coming from one of the bolts on the mounting plate of the RD1C. I am going to have to look into this leak a little farther. Never ending oil leaks. I can handle to leaks, at least I know where they are. Any suggestions with the idle tuning. I think I might have to purchase the Data Logger from Tracy in order to see all the values. Luckily, I already wire for it, I just have to hook it up.
