Changes by last author:

Added:
* low-Z injectors

* 2.5 Ohm (measured)

* injopen=10 # "injector opening", try 00

* battfac=03

* kpafac=4D

* kpaoffs=80

* injocfuel=0D

* injrampup_battfac=0D

* injpwm=40 # 25%

* injpwmt=0A # full voltage for 10*100usec

* injpwm6=40 # added inj. PWM for lower voltage

* fuelcut_min_kpa=19 # cut fuel below 25kPa (a bit too high, more usual is 14..20kPa, so use 09 or 0A)

* fuelcut_max_kpa=DC

* '''ECU applied with powerflyback ? likely

** Confirm that EC36pin23 (flyback) is connected to injector-common (+12V)

** EC36-pin23 flyback injector common +12V (injektor kozos +12V-ra kotni) NAGYON FONTOS

* remember that TPS>65% enters flood-clear mode ( 65% feletti gaz inditozaskor lekapcsolja a befecskendezest!)

* full time: 1ms

* PWM-DC duty: 25..29%

Injection sequence: (sorrend)

* divider=01

* alternate=03

DAMAGED outputs on v3.3 serialnr 523 ( elrontott kimenetek; minden bizonnyal rossz flyback bekötés vagy rossz GND-GND5 miatt? )

* EC36pin7 (Injector channel A) is damaged (folyamatosan spriccel!)

* EC36pin19 (Injector channel B) seems working, but internally same FETdriver as for pin7, so avoid for safety (látszolag jól megy, de belül ugyanaz a FETdriver hajtja meg, mind a ec36pin7-et, szával kerülni érdemes, pláne eleinte)

Injector outputs (bekötött kimenetek) - see GenBoard/Manual/DigitalOut/Table

* Cyl mask Family Number h[0] mask Pin Name Max Load Comments

* cyl4 08 INJFET 3 08/8 EC36 pin20 Inj D 10 A Injector driver

* cyl3 04 INJFET 2 04/4 EC36 pin8 Inj C 10 A Injector driver

* cyl1 64 INJFET 6 40/64 EC36 pin6 Inj G 10 A Injector driver

* cyl2 128 INJFET 7 80/128 EC36 pin17 Inj H 10 A Injector driver

in MegaTune "h[0] injection sequence" (note the reverse order - forditott sorrend):

* 128 (cyl2)

* 08 (cyl4)

* 4 (cyl3)

* 64 (cyl1)

* 16 (fuel pump)

* ...

* ...

* ...

----

Fuelpump (AC)

* engine_off_delay=08 # 8*0.25=2 seconds after engine off

* pump_on_mintime=10 # 16 * 0.25 = min 4 seconds after powerup

Output selection:

* fuelpump_channel=40 and

* h[0]=80 08 04 40 10 00 00 00

(index 04 is mask 0x10)

So according to GenBoard/Manual/DigitalOut/Table mask hexa 10 means

* fuelpump relay negative is controlled by INJFET 4 10/16 EC36 pin 9 Inj E 10 A Injector driver

* fuelpump relay positive is fused and switched (node15, only live when ignition is on) +12V

serialnr 614 maybe RS232 was broken (by same setup that damaged 523 ? ). It normally works fine, with some glitches (RPM falls to 0 in MegaTune).

Both 614 and 523 were upgraded to firmware 1.0.53
