Hello, my name is Axel Wall,

I live in Sweden, 18 years old.

I have now built a "new" engine to fit my Volvo 164E -72. The 3.0L engine will be Supercharged by an 4-53 Roots blower, and intercooled with an air/air intercooler from Volvo V70T5, I will weld two of these together later...

Some aditional info on the engine:

Ported head. (by me.)
About 8,5-9;1 CR.
1,2-1,4Bar boost pressure
COP from BMW -99 (same as M3,M5...)
Running on Ethanol (E85 85% alcohol, 15% gasoline)

Config & Tables

[COP on the engine, in engine stand]

[Some VEMS parts]

Sensors and operational devices

Crankshaft Speed/Angular Position Sensor (CS) -Ford EDIS VR-sensor, home made moltitooth 36-1. [The trigger wheel]
MAP -MPX4250AP
Coolant temperature sensor. (CLT) -Bosch D-Jetronic [R/t diagram] [THERMFACTOR_D-jet.INC]
Inlet Air Temperature sensor (IAT) --Bosch D-Jetronic [R/t diagram] [AIRDENFACTOR_D-jet.INC] [MATFACTOR_D-jet.INC] I will use IAT from Volvo 740 TIC (Turbo) later.
Throttle Position Sensor (TPS) -Standard Bosch item 0 280 122 001. 5 kOhm angular potentiometer, without idle and full throttle microswitch.
Idle Air/Speed Control Valve (IAS) - 2 Paralell Bosch x xxx xxx xxx From Opel omega 2.0, PWM-solenoid. [Idle control valves]
LSU4 WbO2
Ignition Coils -6x Bremi 11860/ BMW 1 748 017 [COP_1] [COP_2]
Injectors -12x Bosch 0 280 150 036 380cc@3 bar, connected in series of 2, ~5 Ohm/bank, the banks connected to one FET each --> fully seqential.

TODO

The crystal "Y2" has been ordered from ELFA, and soldered.

Connect V3.2 to PC and upload firmware. -VEMS.HEX uploaded using AVR-Studio.

Fix the Ps2 Keyboard, no reaction at all from Genboard when i press the keys, right/left arrow is the same :( LCD is connected and works really good. The 3 LED's on keyboard flashes when I power up the Genboard. -It works now! wrong pinout on the PS/2 connector..

All the config settings... how to config the coils? Direct fire is the first choise. -I will start running Wasted spark, and trye to solve the triggering later..

It seems like the trigger is faulty too... in some way, maybe config? [config.txt] The RPM reads just 0000 on the LCD. -SJ6 was soldered to ground, so the VR was shorted..

Present

No spark at the plugs, maybe error in config?

Later...

Solder the R's, C's around the DS2480B 1-Wire Line Driver. -What values should I use? 220nF is the best between 5V and GND.

-I'l have a look at it..
