RE: CDI gr8flyer55
HI Jake, The table I posted was from the code that John posted on your web site. I don't know how he got those values. Charlie

RE: CDI gr8flyer55
If you look at the table I posted you will see that there are values bigger then what timer1 can hold.

RE: CDI gr8flyer55
Hi Guys, I tried John's curve and for me the timing curve is right where it needs to be at startup through WOT. Jake, [code] 1448075,2,44,86,128,170,212,254,296,338,380,422,464,506,548,160,152,143,134,126,117,108,100,91,83,74,65,57,48,39,39,41,44,47, 49,52,55,57,60,62,89,117,145,173,200,228,256,286,328,370,412,454,496,538,580,622,664,706,748,790,832,874,916,958,1000,1042,1084, 1126,1168,1210,1252,1294,1336,1378,1420,1462,1504,1546,1588,1630,1672,1714,1756,1798,1840,1882,1924,1966,2008,2050,2092,2134,2176, 2218,2260,2302,2344,2386,2428,2470,2512,2554,2596,2638,2680,2722,2764,2806,2848,2890,2932,2974,3016,3058,3100,3142,3184,3226,3270, 3315,3360,3405,3450,3494,3539,3584,3629,3674,3718,3763,3808,3853,3898,3943,3987,4032,4077,4122,4167,4211,4256,4301,4346,4391,4435, 4480,4525,4570,4615,4660,4704,4749,4794,4839,4884,4928,4973,5018,5063,5108,5152,5197,5242,5287,5332,5377,5421,5466,5511,5556,5601, 5645,5690,5735,5780,5825,5869,5914,5959,6004,6049,6094,6138,6183,6228,6273,6318,6362,6407,6452,6497,6542,6586,6631,6676,6721,6766, 6811,6855,6900,6945,6990,7035,7079,7124,7169,7214,7259,7303,7348,7393,7438,7483,7528,7572,7617,7662,7707,7752,7796,7841,7886,7931, 7976,8020,8065,8110,8155,8200,8245,8289,8334,8379,8424,8469,1329068,1334735,1340402,1346069,1351736,1357403,1363070,1368737,1374404, 1380071,1385738,1391405,1397072,1402739,1408406,1414073,1419740,1425407,1431074,1436741,1442408 [/code] I have a question though in the curve John is using 1) above table the first value is 1448075. how is that usable? Its bigger then the biggest number that timer1 can hold and there other values similar. 2) the table has a 2 as the second number it seems that the numbers should go in some kind of order. 3) the first row it seems that the numbers are all over the place (example) 108,100,91,83,74,65,57,48,39,39,41,44,47, 49,52,55,57,60,62,89,117,145,173 Now I am guessing that at lower rpm the pic is using the numbers at the end of the table and as the rpm increases the pic uses the values closer to the beginning? is this right? as I mentioned on my engine sim using a timing light the curve is where it should be.(IMO) Thanks.

[quote] One thing to point out is that if your hall sensor is at 30 deg, you can't have a 30 deg advance setting! [/quote] Why? Can't you just have no delay? Anyway I tried out the latest spreadsheet and I have a new problem. Now at 5000 rpm the ignition stops firing. below 5000 it starts again. Also the curve is no a smooth transition it bounces from full retard to full advance.

RE: CDI gr8flyer55
OK I have tested the latest version on my engine sim an dusing a timing light the curve that is supplied with the code is no good. at 200 rpm the curve is below tdc and max advance is never reached. To me the curve should be at 5 degrees from 200 rpm upto 1300 or so. Then advance the timing with rpm upto 4000. from 4K and up max advance should be obtained. I know I will have to play with the spreadsheet.

Hi John, I am using MPLAB v 8.85 and using XC8 C compiler v 1.10. I have a few questions 1) Did you (in MPLAB) select the xc8 compiler as the tool suite to use? 2) did you use the project wizard to create a project and add the .c file to the project? Charlie

RE: CDI gr8flyer55
[quote] Where is probe 2 attached? Is that the firing signal from the PIC? If so, that does not mean there is a spark for every trigger signal. [/quote] That should mean 3 sparks for every trigger signal.[;)] Prob 2 is connected to the timer board output signal line. 360Us is too small of a delay for the human eye to see. But you can tell the spark behaves differently then without the pic controlling the timing. So I would say it does have some effect. You can't expect to see 3 distinctive sparks per trigger.

RE: CDI Summary (The New, New CDI Thread)
Hi Jake, OK Thanks. The reason I ask is If you are going to port the asm code over to C then I guess some people will want to edit the advance curve and will need to know the compiler used. Please what ever you do don't port it over to Atmel !! [;)] Thanks for doing this.

Well if you use a bootloader then you can program the pic with a serial connection.First you have to program the bootloader into the pic.So if you have a pic programmer then you can just program it with the original hex.
