Summary of change:
Hi, I'm an IT Architect for a living. Unfortunately I don't get to play with designing or building Microcontrollers so I am trying to learn in my very few spare moments. The Genboard v3 will run my 1988 Mazda RX7 Turbo. I live in Burlington, Vermont USA. Just for fun, here's a link to a webcam near my house. http://www.hazecam.net/burlington.html MembersPage/JasonRussell/MazdaRX7 MembersPage/JasonRussell/HondaDelSol 1988 Mazda RX7 Turbo Here is a picture of the crank angle sensor: Notice the 24 tooth wheel at the bottom(crank position) and the 2 tooth wheel at the top(of the Z axis). The 2 tooth wheel is the crank TDC (home position) for Rotor 1. This assembly turns at 1/2 crank speed like a distributor would hence it's 30 degrees of crank rotation per pulse with a seperate pulse for home position. http://www.6speed.org/ms_avr/rx7cas.jpg As for the coils, the Haltech guys use 4.5 - 5ms dwell time on the stock coils, so I figure I'll start there. The split trailing should be fairly easy. Although it will most likely require firmware changes (#ifdef ROTARY). Visit my website for more info on my cars. http://www.6speed.org ---- I am starting to prepare for the install into my RX7. Here is a pic of a board with the way I populated the components. I describe below the pic. http://www.vems.hu/files/MembersPage/JasonRussell/genboardv31_top_rx7.jpg A = Rotor 1, primary Injector B = Rotor 2, primary Injector C = Rotor 1, secondary Injector D = Rotor 2, secondary Injector WB = Wideband switch of course L = Wastespark coil for leading (bottom) sparkplugs T1 = Coil driver for trailing (top) plug on rotor 1 T2 = Coil driver for trailing (top) plug on rotor 2 I'll be using both VR inputs for the above sensor, knock eventually... any additional suggestions? Q: Where is the switch for the fan relay on v3? I don't see it on the EC pinout. pick one (and we should definitely have some standard, so check the sch and check the code; code is quite flexible, eg. mik uses an ign259 channel, because he started his engine before he had TPIC6A259DW chip). Q: What is recommended to use for the transient supression diode near the power supply? U$5 is 1K5E18 or 22 (18 or 22V) throughole transient suppression diode, it's legs are very thick. It's in the rescue kit for some time now. Not a big problem if you don't mount it. * This wasn't in either RescueKit you sent me with the 2 board pack. Not a problem. I'll buy a few and mount it later. I still have almost a month before the next race. Q: Is there a predetermined use for JP1 (SDA/SCL) or are they free outputs? I'm trying to determine what pins to bring out to an external connector for future use. A: These are free, they are wired to the I2C pins of the MCU and there is lots of useful I2C devices. ---- WBO2 test/setup Here's the config on my controller now (this was used to make the wbo2logs posted) wbo2_warmup_ramp=A0 wbo2_warmup_target=FF wbo2_abs_limit=E4 wbo2_limit_maxt=A0 wbo2_fallback=60 wbo2_retry_t=06 wbo2_edgetime_corr=BA wbo2_edgetime_min=50 wbo2_ri_target=96 wbo2_nernstdc_target=8D wbo2_pump_pw_zero=65 wbo2_calibration=D0 wbo2_heater_pid_kp=46 wbo2_heater_pid_ki=10 wbo2_heater_pid_kd=1A wbo2_heater_pid_ilimit=80 wbo2_pump_pid_kp=2E wbo2_pump_pid_ki=1D wbo2_pump_pid_kd=08 wbo2_pump_pid_ilimit=84 wbo2_ri_confidence_scale=80 Measured values: *** If the IN+ (pin3) is about 4V, and OUT (pin1) is close to +power (eg. 10..11V) than too much current is drawn by something loading pump-. You can make the 270 Ohm resistor (pin1 -> pin2) smaller but it worths to check where the current goes. Solution: Put the 270 ohm resistor on the board. Works wonders. ;-) The GenBoard/Manual/WBSensorConnection page was misleading (saying they are all auto-placed) so I changed it for that component since all boards I have in stock are missing that R. ---- Here is a log I took tonight of a full warm-up. Any comments on this? (it's still greek to me) http://www.vems.hu/files/MembersPage/JasonRussell/8_15_wbo2logs.tar.gz This is broken!! The documentation is lacking on finalizing the setup of the wbo2, so I hope changing that will help solving my own problems.
