Maximum planned boost is 0,8bar = 11,76PSI = 80Kpa, so max MAP reading will be 180KPa.

----

Rev limit 7500 RPM

No need to test EDIS on table (if it works at such RPM), since EDIS module will not be used. Only the coil and VR sensor from an EDIS setup (those will work at 7500 RPM).

Project state

DONE

* connected all the wirings and sensors to the engine, diagram can be seen here: MartinFranck/Wiring

TODO

* document what is done - eg. trigger position and ignition channels

* complete config.txt

* have config.txt reviewed

* upload config.txt to GenBoard

* some table-testing wouldn't hurt (!)

* fire up the engine

----

Sensors - already mounted:

* Knock-sensor

* Map-sensor (Ford cosworth, 2,5bar magneti/weber)

* TPS-sensor

* Water-temp

* Air-temp

* Coilpack and Trigger sensor from the Ford EDIS system (not using the EDIS4 modul).

----

Idle air

* not under GenBoard control ?

----

Trigger

* 36-1 crankwheel (Home one can be seen here MembersPage/MartinFranck)

* VR sensor.

The primary trigger input channel must be set up with the relevant jumper to VR-type input (so LM1815 is used). The other option would be HALL type. I will check it for you if you describe or draw the primary trigger connection (all - about 8..10 - components and jumpers that are on the board!) from EC36 pin to all the way to LM1815.

You can upload pics of the board (both sides! with sufficient resolution) so we can verify. The middle section is most interesting, from EC36 pin27 to LM1815 chip.

Ignition

Wasted spark: 2 channels for 4 cylinders.

* 1 and 4 fire together (PIN 34)

* 2 and 3 fire together (PIN 36)

Coil pack is from Ford EdisIgnition, so starting dwell is 4 msec. (Got it from a friend who is driving with the same type of coil).

You can verify with the power consumption check, see DummyIgnition. Starting the tests with shorter dwell would sound safer.

Pin connections and h[2] table

Some very important settings like

* h[] table, h[2] line. See GenBoard/Manual/Tables

* trigger_tooth

** the missing tooth are at the same mark as the top mark on the engine block and at that point Cyl 1-4 is in top position, this is 93 deg after the VR trigger.

- but this has no information (or unclear at least). We need to know where the TDC of cyl1-cyl4 TDC is at when the tooth after missing tooth just passes the VR sensor

** so isn't the missing tooth = trigger_tooth (answer the above and we will find out this)

* ign_tdcdelay (0xBA*0.5 = 93deg) is this correct?

will depend on

* which 2 ignition channels are used

* the TDC after the missing tooth is .... degrees (... tooth + ... degress) and belongs to

** cyl1 and cyl4 or

** cyl2 and cyl3

This is of critical importance to document precisely.

... coming up

----

config.txt

http://www.vems.hu/files/MartinFranck/MFConfig.txt

* ign_tdcdelay=BA (to reflect the 93 deg. BTDC, which is 200 decimal because of 0.5 degree resolution. This is important.

* trigger_tooth=00 (0x00 means the missing tooth)

----

Ignition advance table

described in the n[ ] table (8x8 or 16x8)

Obviously, lower ignition advance is needed at highy MAP (> 100 kPa is possible because of the turbo). This means n[7] will hold lower values than n[0]

The following kpa and rpm ranges could be used (or other can be good too):

r[0] = 07 ... <5 RPM values of your choice> ... 40 48

k[0] = 18 40 64 90 B0 ... <2 values of your choice> .. FF

You don't need too many bins initially, it just increases tuning time. For ignition during the 2nd phase (fine-tuning) you might find it a good idea to insert an rpm or kpa bin somewhere, so keep one "free" during the first round (spread your useful range across 7 bins and place the 8th somewhat beyond).

-------------------------

Question

*I have I understood it correctly, when if I want the ignition advance too be 30 deg, that i should multiplicat with 2, so that I should write 60 deg = 3C (Is this correct)
