If you wish to retain sequential staging you will need to use the V88 (Has 8 injector drives)
On the V44 you could run group staged. This would drive the primary injectors off drives 1-2 and the secondary injectors off drives 3-4. (two injectors per drive).
-
Injectors will need to be paired up. So two injectors per drive.
Most of the numbers can be manually copied across. You just need to configure the tables to match.
-
IAT reading high will actually remove fuel. (this is a minor trim and should effect the initial start up)
Haven't seen it on v3-4 before but on the v5-6 Subaru some of the late cars did run the later V7-9 type map sensors.
If it reads correct at atmosphere then you will have the correct sensor.
I suspect the biggest thing you are going to need to do is lower the master fuel number.
Are you running stock injectors ?
-
You want the TPS position to read 20 - 100 the TPS High and Low numbers are the raw value the micro uses.
They need to be what ever is required to get the position correct at either end.
-
Its going to something distributor based. It will depend on the sub-board fitted as to what. Only way to tell what will be if you can get a photo.

Hi you are on to it.
The system is the same as the Nissan one.
If you follow the set up the same as for Nissan you will be on your way.

It was for the BMW V10 up until it was discovered the engine was odd fire.
We have a customer that is investigating using two ECU's on the V8 currently to allow 4 cams to be controlled.
We will find out more as they progress. To date I don't think any one has done it.

Hi if you could email map that would be great [email protected]
I have had a quick look and it seems there is an issue.
Fortunately an easy one to fix. I will get engineering to confirm and then advise.
-
Our testing was done on the STi version.
-
The way to tell is to see when the ECU shows RPM. As soon as it see RPM then it should be trying to fire.
If it is taking a long time to get triggers then it will take a long time to start.
If however it sees triggers and RPM quickly and doesn't fire then we are looking for another issue.
Also if you are using a stepper motor for idle control it might be due to a key on lockout while the stepper resets.
-
If you measure the voltage out of the sensor with a multi meter and see if it changes.
If you get no change with pressure then the sensor has failed.
The sensor should have a ground 5V and signal.
-
-
In the trigger cables you have a ground in each cable one of these can be used to ground the sensor.
The 12V for the sensor can come from a switched supply such as the ECU's 12VÂ
Trig one and two will be identified in the pinout for the Storm and a continuity check will confirm the correct wire at the end of the screened cable.
-
We can only do control for 2 Vanos solenoids due to their push pull nature (2 drives per solenoid)
On the V88 only drives 1-4 can be used for this function.
V88 is also only geared for a single E throttle.
-
First thing to check will be that you have resistive plugs fitted. This is very critical on wasted spark applications.
Also look for any errors in RPM reading or triggers in the runtime displays.
-
I would definitely start by getting the latest firmware installed.
If still no luck if you email your map through we can try to replicate the issue on the bench.
-
Check the AN volt error settings. And also that you don't have MAP selected on another AN Volt channel at the same time.

Hi Nigel
The 0-5 could be used as an input to the ECU but is not as effective as using windowed knock using the Vi-pec interface.
For pricing you will need to contact your nearest dealer.
-
I suspect the main relay is not turning on. Coils and Injectors will also have no power to them.
The fuel pump could run if the ECU is not powered but the pump has power. This can happen through a back feed.
Way to tell if our ECU is powering up is to see if there is a green LED lighting up on the board. (does require lid off the ecu case)
-
You can try changing the edge on trigger 2 and see if that will work. It should give you the same cam trigger points. But your main offset will need to be checked again..
-
Assuming this is a linear sensor the following set up could be used.
-
The only thing I think that might be causing it could be that your main offset is a long way from 0 where we are expecting it to be.
The Cam edges in the image are only 2deg from where we are expecting them to be.
-
We are geared for a 0-5 signal. A low voltage for no knock and a high voltage for knock.
-
Best option will be to do a Log all with PCLink
That way you don't miss out on any parameters should you need them and also logging memory space is effectively unlimited.
You should look for AFR, Ignition angle, Dwell, and trigger errors

There is a issue if you have fuel pressure selected as an input. If this is the cas you can set the input to a general 0-5V and the wideband 02 control will then work.
We have a fix sorted and will be in the next firmware release.
