Problems faced:
1.1.23 release
16x14 firmware package, with Megatune did not work.
- Firmware signature do not match with supplied Vemsv3.ini.
Tried also 12x12 and yet still signature do not match.
Expects '....=4.D' or something, but Vemsv3.ini file(s) distributed with the package do contain '....=2.2' and '....=2.1'.
Then downloaded 1.1.8 firmware version to ECU, and set Megatune (Vemsv3.ini etc.) settings accordingly.
Megatune starts now OK, without errors.
Then made settings... only to find out, that the 1.1.18 version is compiled with Ign_Dualout commented out. -> So were unable to use COP layout in waste spark mode. In fact only one (1) spark channel fires despite of what settings are.
Excerpt from FirmwareChanges states that...
<clip>
[1.1.18]
ign dualout (very special config) was broken in last few releases: fixed
</clip>
Is it firmware or settings related, I don't know, but mcd and mct listed in below if someone has a clue.
Also there is electrical problem with MAP sensor
(ecu no# 184, which was supplied without MAP sensor onboard).
- Map (internal MPX4250 (254 kPa) sensor soldered) displays wrong pressure (around 29 kPa when exposed to atmospheric pressure). Pin 3 measures 4.88 volt, pin 1 measured 1.1 volt at (1007 mBar) ambient pressure.
- MAP value 'creeps'/increases (in fact it rails) when throttle is opened to 255 kPa. (Note ! engine is not running)
Connected external MAP sensor (in place of internal sensor, which were desoldered from PCB) but this did not help.
Still MAP value in Megatune reads (30 kPa at ambient pressure) and does not react pressure change. MAP value in Megatune climps from 30 kPa to 255 kPa when throttle is opened (Note ! engine is not running).
So the MAP value follows the TPS value, how that is possible and what to do to correct it ?
Is there v3.2 schematic and fault finding instructions published (obviously I need MAP schematic etc. info), and if then were ?
Did not found such an information from wikipages.
Engine specifications:
- v3.2 ecu #184
- Toyota MR2 with the 3S-GTE, 2 liter inline 4 cylinder, turbocharged engine.
- 60-2 wheel fitted to the crankshaft. Toyota OEM crankshaft VR sensor is relocated to read the 60-2 type wheel.
Trigger location to the TDC:
- First tooth after trigger (ie. missing tooths) is located to the 90 degrees before cylinder one is at TDC.
Sensors and devices connected;
- COP installation (Denso pen type coils).
- Denso four hole injectors (checked flow rate is 560 cm3/min). * Bosch knock sensor.
- Bosch idle valve, double coil type.
- Toyota OEM IAT and CLT sensors (similar to Bosch 2252).
- WBO2 sensor connected (and calibrated).
Knowledge for the ECU settings is needed;
Settings problem...
- Only one spark channel fires, despite of settings tried. (Other spark channels are also functional tested by changing h(2) table value at xx xx xx 01 xx xx xx xx position. Other positions to the left do not fire (in COP mode).

- seeking correct settings for the ign_dual out
- and/or with cam sync sequential
- is there clear document (with examples), how to setup these ?
- dual out is confusing -> channels restricted. Manuals (wikipages, even most clear Phatbot etc.) do not clarify nor underline the fact that the channel combination is restricted.

- first 2 channels is in use, but only second channel (valued 30) fires.
- then if first four is set to use, only fourth channel (valued B7) fires.
- tried couple of ign channel pins -> all behave the same.
- Tried ignition channels in 03..00 configuration
- cyl 1 EC36-35/IGN 00 -> 00
- cyl 2 EC36-33/IGN 01 -> 10
- cyl 3 EC36-34/IGN 02 -> 20
- cyl 4 EC36-36/IGN 03 -> 40
- did not work
- Tried ignition channels in 01..00 ign_dualout configuration
- cyl 1,4 EC36-35/EC36-33
- cyl 2,3 EC36-34/EC36-36
- last tried also other ignition channels in 01..00 ign_dualout # configuration
- see the h(2) table
- Fuelrail injectors (fully sequential wiring).

Summary...
- no secondary triggering used/connected
- Wasn't able to use ign_dualout (1.1.18)
- wastespark only fires (first phase) channel.
Need;
- an waste spark (does it need cam sensor) or ign_dualout settings.
- information how to diagnose/fault find/correct etc. MAP circuitry
- to study ign_dualout, examples and clarification of bit values
