Want to do a PnP install on my Mazda 323 GT-R but also on some Group H Rallye Cars.
Hardware is 90% done.
Sotware is 20% done.
Questions:
Q. TDC is 84° after rising edge of primary trigger. Ignition advance gets up to 55°. Now Coil charge time gets down to about 1,5ms on 6500rpm but i want at least 3ms. Is there a way to start charging before the rising edge?
Q. Does anybody has working Tables on this engine? Because my Genboard does exactly the same as factory ECU but the engine doesn't run good.
Q. Is there a way to change the starting point of fuel injection?
Specs:
Engine:
- 4cyl
- 1800ccm
- 440cc Injecotors
Ignition:
- Single Coil + Distributor
- Ignition Module (using Logic-Level Output)
Trigger:
- 4+1 Cam Sensor
Sensors:
- Flap type AFM
- TPS
EMS:
- Genboard 3.5
- Firmware 1.1.50 (downgrading to 1.1.27 until engine runs perfect)
Progress:
Hardware:
- Genboard installed in factory ECU case
- installed additional 9pin connector for IAT, MAP and WBO2
- MAP/AFM, IAT and NBO2/WBO2 swichtable
- WBO2 and MAP sensor have been already installed in car for a ZEITRONIX WBO2 Display
- built a trigger emulator with mega8 uC for testing
TODO:
- install EGT
- check if factory knock can be used with vems
- intall wasted spark ignition coil
Software:
- Measured Trigger with Scopemeter
- Measured ignition timing of factory ECU
- Measured injector pulse witdh of factory ecu
- Engine starts and runs but very badly
TODO:
- Get engine running stable with AFM
- Get engine running with MAP sensor
- Values for warmup and acceleration enrichment doesen't work good
- Get WBO2 working
- Get wasted spark ignition working
- Boost control when using MAP Sensor
- ALS/Launch Control
Information:
Trigger:
Same Trigger as on [MembersPage/Fero] but i measured angles with scopemeter and got this values:
Ignition:
Factory ECU has no ignition table. timing is calculated of rpm and AFM voltage. Tested up to 30000rpm.
Fuel:
factory fuel table measured with scopemeter:
