So had the Bomber out now for several rides with the TC4080 conversion. One of things I had to do was change the pole count from 12 to 62. With the correct wheel set at 1925mm, I was hitting my CA V2.25 99MPH limit and shutting power at around 7MPH. So, with the help of my Garvin GPS, I set out to find the correct settings for speed readings. First I went to 23 wich is the correct pole count for this motor as it has 46 magnets. It helped a little, but I was still hitting 99MPH and shutting down, but I was going somewhere around 18MPH when that happened. So I started experimenting with increasing pole count settings. Well, with the pole count set at 62, everything is perfect. CA speed display is 42MPH and GPS is 42MPH. Also distance traveled measured accurately within 10 meters, and that difference could be the time it took the GPS display to update. I don't see any problems with running the pole count this high. I had posted earlier that the WOT speed of the TC4080 was 2600watts, about 900watts less than the 5404 under same conditions, but that was with only adjusting the CA wheel size setting to 500mm. Now with the wheel setting correct and pole count increased, I am seeing right about 3000watts now. This makes more sense as this amount of watts consumed is about the same, just slighlty higher, than my Fighter @ 41MPH after terminal velocity is achieved. So my question is: why does my CA V2.25 need the Pole Count set at 62 and not 23 to work properly with the TC4080?
///Edit 500mm not 5000mm for wheel size ///
Found the culprit, when I first got the TC4080, the phase and sensor wires were way to short. So I chopped the phase wires off down near the axle and stepped in 10g wires like I did on the 5404. Then I had to splice and extend the sensor wires. There are 5 tiny 24g wires that I had to individually splice and resolder extensions too. Well, because they are so small, and I was using a 140watt solder iron, I couldn't put much heat time into each wire. Long story short, reinspected the wires and discovered one of the splices, redish/orange wire had a cold solder contact. it was floating and touching each other but for all intensive purposes was two separate wires. So I heated up the splice. Everything works perfectly now, 23 pole count for settings and display is accurate.
On another note. For the last couple of weeks, I have been seeing a yellow and black Sondors fat tire ebikes cruising around my neighbor hood. A few days ago, I was walking home from the gym, and saw a younger guy, riding the black one. I asked him to stop and let me check out his ride. The guy bolted, I guess I look scary or something. Anyway I sprinted to my house which was about 1/4 mile away. Took me like 75-80 seconds to get there. In my defense I had a back pack with over 20 pounds of gear on. I grabbed my Fighter and hauled ass looking for this guy. Couldn't find him. Today, saw him again while riding my Fighter. I called him out saying "whats up?" "I knew I would see you again". And before I could ask any questions, the guys says, "I don't have time to talk, I have to be somewhere" and bolts pedal assisting his ass off with the Sondors WOT. I couldn't resist, so I pedaled behind him, pretending that 24MPH was hard to achieve and yelled that his bike was fast and hard to keep up with. Guy turns back towards me, and then pedals even harder hitting 26-28mph. Well, I twisted the throttle and caught him. This startled him and he flinched and had a sympathetic reaction at the handlebars and almost rear-ended a parked car. Anyway, I made a positive comment about how fast his bike was and how fuqing HUGE his tires were, twisted the throttle, and disappeared from his view. At first, I thought the whole interaction was funny, but then when I started reflecting objectively about the interaction, a couple of things became apparent. First, this guy didn't know my Fighter was an ebike with about 12 times the power as his ebike, if he did know, he wouldn't of tried to out run me because that would be futile. Second, I don't think I look like an intimidating scary person, I am only 5'11" and 235 (loosing weight
