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
My brother's car that is going turbo
A rally/hillclimb car I installed and take care of
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.
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).

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.
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.
Here's the config on my controller now (this was used to make the wbo2logs posted)
- 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)
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.
