The main ignition table is used for cranking ignition timing. You can make the cells at 0 rpm to 300 rpm and 100kpa to 70kpa any value you need for starting.
If the engine has big cams and low manifold pressure, then it should be mapped using these settings,
Fuel Equation Load=MAP
Open Loop AFR = On
Fuel table Y axis = TPS
Ignition table Y axis = MAP
The EVO have hall effect sensors for the crank and cam signals. We have never had anyone with problems with these signals and do not see any reason you should need to log them.

Yes there will be a plugin. Do not have a date at the moment.
-
Auxiliary outputs 5,6,7 and 8 must be used to control a stepper motor idle valve. No other outputs can be used.
On the version 1-2 plugin ECU these outputs are used for,
Fuel Pump Relay
A/C control
Purge Solenoid
CE light
-
The minimum required, will be one driven wheel and one non driven wheel.

That happened to me the other day. I had a dash plugged into the CAN/RS232 port. Rather then remove the cable at the ECU I disconnected if from the dash and found I could not get the software to go online. This is very odd. Now you have had the same thing happen, it is repeatable and not just me. I will get it fixed.

There is no limit on the number of cylinders or trigger type on any Vipec ECU. To use the plugin as a standalone you will need a very good knowledge of the EVO9 pinout. I cannot help you with this information.

Yes you could use it as a standalone ECU on some other engine.
-
Electric motors are controlled with a PWM (Pulse Width Modulated) signal not by varying the voltage.
The Vipec can control the motor using PWM. Select an output as a GP PWM. Set up the table with coolant temperature as the axis of the PWM table. Values you put in the table will relate to motor speed. With 0% the motor will be off and 100% the motor will be at maximum speed.
There is no option to make this closed loop.

This is not easy to do, and we doubt it will look okay. It may be something we do later if there was more demand.

Anders,
The plan is for the TC to be in the next firmware update on the 1st of April.
-
Make sure the ECU has firmware 4.7.1
Select a digital input as E85 Sensor.
This post talks about how it works at the moment http://www.vi-pec.com/forum/viewtopic.php?f=3&t=485&hilit=e85

There is a PDF file version of the manual on the website under documentation.
-
The last value in any table is used if the engine goes above the value. Example:- If you have a table with 5000 as the biggest axis value, then what every the value listed for 5000 will be used at higher rpm.
If just using the the 24-1 trigger, then select Trigger priority as Trigger 1 and sync mode as None.
-
If you are using the V44 and have a distributor with one coil, then you could use just the 24-1.
If you have more then one ignition coil, then a single cam signal will also be needed. You can use the 24-1 with this setup. I just do not like the idea of the missing tooth, as it may cause problems. Time will tell...
-
I would used the CPS that has 24 teeth with none missing and a single tooth.
-
The CAS does not need to be modified. There is two trigger wheels as required. One with 24 teeth and another with one.
The picture shown in the link you provided shows both trigger wheels.

AFR target table is Open Loop AFR table?
Yes the AFR target table is the open loop table.
-
I cannot find a map.
Trigger Settings
Trigger mode: Multitooth
Sync Pulse: Cam
Trigger priority: Trig 2
Trigger 1
Trigger type: Reluctor
Trigger filter: level 1
Multi-tooth posn: Cam
Tooth count: 24
Arming Thresholds
0.2 1.5 3.0 4.5 4.5 4.5 4.5
Trigger 2
Trigger type: Reluctor
Trigger filter: level 2
Arming Thresholds
0.2 1.5 3.0 4.5 4.5 4.5 4.5
The offset you will need to find with a timing light.

If you had a three position switch connected to an analog input, with different value pullup resistors, you could do this.
The pullup voltage would have to be from the 5volt supply. The analog input selected as 0 to 5 volt. Then use two virtual Aux outputs as the switch for each table.

The Open Loop AFR table must never be changed after you tune the engine. If you do change it the tune will be totally different. You should always have this table turned on before you start tuning. It will make tuning faster, as the values in the fuel table end up being flatter.
This table has nothing to do with narrow or wideband 02 sensor feedback. It is an open loop table, not closed loop. It uses math to calculate the changes needed in injector time, to achieve the air fuel ratios values you put in the table.
Also if you tune with this table turned on, you can make changes to the tune any time later by just changing the values in the AFR open loop table. No retuning with a wideband meter is required.
-
In Analog Settings -> Fault Setting, you can set the limp home value for the Wide band or Narrow band signal.

What engine is this.
The map you sent me is from a V44 with 4.5.1 firmware. The current firmware is 4.7.1
I can phone you. What is your number.
Ray.
-
And why are all my temperatures in celcius lol
Because the USA is the only country to still use imperial...
The map looks okay if the engine is a six cylinder with a distributor that gives six pulses plus a single pulse. That is how the trigger settings are setup.
One thing that does need fixing is Auxiliary Ignition output 4. It is set to ignition. Must be set to off.
I would recommend you update the firmware to 4.7.1 before starting the engine.

With the V44 you would select Multi-Point Group and active drives as INJ1-4
Send me your map so I can check all your settings to save a lot of posts on this forum. [email protected]

Passwrod protection issue

Ask the original owner or the tuner for the map, then load it into the V88 and the password will be gone.
There is no way to remove just the password and keep the map, if you do not have the password.
