Really thinking on purchasing a Power commander like Dyno Tech Jim sells and would like to if any one has lost a D8 while running the supplied maps for thier sled
I have the PCIII on my assault with a map from Jim on it, however my sled has the latest poo reflash so I installed my wideband fuel gauge today to dial my sled in when I head out next week.
Jim was supposed to be redynoing a 800 with the new reflash so they could update the numbers of the pc3.
sorry for the repeat, this is my post from the "scuffing" thread......
i am running egt's on mine. unfortunately, i only recently put them on.....about 300 miles into a new sled. wish i had them on from the start, during breakin. i have a slight bit of exhaust port scuffing. i have installed a PCIII with slp's map and the new reflash. i only have about 3 rides on that setup unfortunately (damn work!). i also now have a mac and not a pc. this is what i have seen so far (riding 9-11k with slp pipe), there is a range from near 6000 rpm up to about, i think, 66-6700 that seems lean. i have no bog, but if i hold those rpm's for any length of time, my egts will head past 1275. i have actually richened it up with the buttons (don't need a pc to do that) on the high end (6-9000 rpm)...made it a tad better, but still not happy in that range. with this setup, it is too rich on the top. right now, i just make sure i watch temps and vary throttle position, if in doubt, pinning it cools her down. as soon as i can get my hands on a pc, i am going to make a few different maps and put them on an SD card so i can choose from them in the field and see if i can dial it in. i'm quite sure that during break in, i was getting it hot from what i see now. i had a exhaust valve bolt break at the cylinder....they were unable to extract, so i have new cylinders but they had no piston kits on hand and i had a big trip coming up. we will probably end up replacing the pistons due to the scoring. hopefully i will have the map dialed by then. there is NO doubt that in the 6's it is getting hot, even with the new flash. the slp map only added fuel in that range, but it still seems lean. i will post more when i know a bit more.
can you modify the fuel map that comes from SLP or do you have to start from scratch? Also, when you make adjustments can you make them at more precise increments than 6-9000 RPM? Like 1000 RPM increments all the way through the range? What is considered optimal EGT temps on an 800 and what would be the high end dangerous temps?
Thanks in advance, I know it's a lot of questions!

I have two 800s and both have different fuel needs. I run EGTs and a power commander on both. Each one is mapped differently. the common thing between them is adding alot of fuel between 5500 and 6750 at 10 and 20 tps settings,also leaning them down from 7500 and higher at 80 and 100 tps, at the lower rpms 5500 to 6750 I have added as much as 17 percent fuel. I would not drive a 800 without an EGT guage and a PCIII or boondocker box. I could take a new sled out and burn it down in 20 minutes.I also run 1 gallon of 110 octane gas to 4 gallons of 91 octane non-ethanol with wires plugged in on ECU. I have also noticed that running more 110 octane does not slow it down like you would think.I think the head design could use some improvent. The PCIII is very easy to use.In a couple of hours you can start with a base map,drive it watch your egts and rpms come back to your laptop and plug into PCIII and put in new numbers and try again until EGTS are okay. 5500 to 6750 are 10 and 20 TPS. I have Koso EGTS and wideband O-2 guages on both. I feel you only need EGTS. The PCIII with the EGTS is very easy to use and fun to tune. I hope this helps some of you make a decision. If you do not buy anything make sure you vary your throttle alot and pray that you are lucky.
