[Configuring CAN BUS setting for g4+ to Racepak iq3]

Hi, How did you go with this mortenkapi?  I've got a Link G4X that needs to connect to the Racepak IQ3 also.  I too have the cable.  It works well with the wolf v550 but have since binned the Wolf ECU ..

 

[Motec E888 with Link Extreme]

Hi,

I'm wondering if this has progressed at all.

 

I'm running out of inputs on my Link G4X xtreme and could do with more.  Also outputs that I could move over to the e888 would allow me to look at using dbw on the race car.

 

Any feedback appreciated

In multipoint group mode the injector drives are fired in 2 groups, all even drives fire together and all odd drives fire together.  

Whats the injector resistance?  If low impedance, does it have a ballast resistor?

The ballast has been bypassed.  They are high imp injectors. 

 

I've wired injectors

Output / cylinder

1 / 1 and 2

2 / 3 and 4

3 / 5 and 6

 

 

 

[V44 wire in ecu in a 6 cylinder]

Hi, I’ve got a Vipec V44 in a car that I’m repairing and the engine is a 6 cylinder V6 6G72. 
Since the V44 can only support 4 injector outputs, I am short 2 outputs. 
I believe I will have to wire them up in pairs and run them in pairs. 
 

The firing order for the 6G72 engine is 1-2-3-4-5-6. 
 

I’m assuming I wire them up in pairs of:

1&2, 3&4 and 5&6.

 

settings should be multipoint group injection.

Please let me know if I’m on the correct path to this setup.  Thank you

[PWM output to control factory boost gauge]

Aux 3 will be fine and it should work connected directly.  I have no idea what frequency the factory gauge uses though.  

Thanks, Trial an error for freq i guess....  From factory, they always seem to lack accuracy anyway...

 

[PWM output to control factory boost gauge]

Hi there,

Another thing on my to do list is to control a factory boost gauge via an aux output (pwm most likely ) to also dynamically move as boost target changes.

 

I don't know if it'll be possible but as a baseline, at least have a boost gauge that somewhat works.

 

It would be great if the needle / gauge output target moved as boost target changes via an AV potentiometer.  

 

Here are the photos of the gauge.  I'm assuming AUX 3 can be switched a pwm ?  Would I need a pwm to AV convertor of any sort ?

 

A good write up here.  Probably a good starting point.

"Chromedecu.org | Boost Gauge" http://chromedecu.org?page_id=889

 

Any known feedback?

Will it work? Do I have to use a specific output ?  My high level drawing attached.

Did you try the master fuel higher as suggested earlier?  Do you have a spark when cranking?  Have you confirmed trigger offset with a timing light?

Yes. Set to 15ms.

Spark confirmed using test only via test light.  It was odd actually with the test light test.  Although waste-spark, one cylinder would trigger the light in test mode but not the shared cylinder.

I thought maybe the spark plugs were cactus and yes.. they were fouled and in a poor state.  I tested the spark again after removing spark plugs and the test light now worked when spark plugs were arcing to the head.  I'm replacing spark plugs and will give it another go.

Note: 

Spark was not confirmed while cranking (lockdown here. Doing this solo at the moment).

 

Does the log indicate that ignition is being triggered correctly along with fuel ?

 

As long as they are doing what they should, I'll replace plugs, upgrade injectors while everything is apart also (not the best motor to work on).

2. Stock injectors master probably 20-30ms.

3. You can lock the timing to whatever value you like.  Read the help file page: VX ECU Tuning Functions > Triggers > Calibrate
 

ok so no luck tonight.

I checked each coil and they all fire in order using test function.

1 fires 1 + 4 

2 fires 2 + 5

3 fires 3 + 6

Fire seq = 123456

 

Injector test ( i only verified 3 front injectors ( 5,3,1) and they all correctly align with injector outputs 5,3,1.

 

I dont even get bangs or pops which usually relate to a sequencing issue.

The CAS hasn't been moved from the factory ECU position.

Am i missing something?

Ignition switch inputs changes state and starter signal changes state when starting.

ECU hold is constant.

Triggers look OK.

No limits that i can see stopping it from firing up.

Attached is a log file and the PCL file.

Any further help appreciated.

Would love to get this thing fired up and setup functions.

Thanks!

The Evo plug-in is still designed to use the factory ECU hold power circuit, so you will still need the main ignition switch input and main relay control as per factory, regardless of whether you keep the stepper or not.  

Ok, thanks.

Will give it a go today and hopefully she fires up.

 

Any advice on questions 2 and 3?

4 has been answered. (ign switch input acting like an immob function).  Also i noticed there is a specific immob function also that could be used.  Pretty handy

 

 

Thanks.

Hold power shows on, so that would suggest the ignition switch input is not working/connected.

I found it. 

 

Sounds like it could be it and it explains the ignition switch function in relation to the stepper motor.

 

A stepper motor delete not only uses 4 outputs but also one input.   I think it'll definitely be on the cards to delete the stepper motor and convert to a 2 wire idle valve..

Thank you for replying.

 

So the ecu needs to utilise the ign switch input in order to activate injectors and spark? as opposed to seeing crank triggers?

What is the logic that the vipecs/links use with the ign swith and ecu hold functions?

My first vipec install and setup.  Much appreciated.  I'll investigate the ign sw input and confirm polarity is correct also.

[First start. Vipec V44. No fuel or ignition. Help please.]

Hi there, 

 

I can't seem to get fuel or spark.

I've tested all my injector and ignition outputs.  I can hear them activating when selected.

It's a plug in ecu (evo 123 ) being utilised on a Mitsu GTO.

I've configured the additional injector outputs and ignition output along with aligned the configuration to suit.  I'm going to validate injector firing order next .

 

My questions are :

1. Run time values - should injectors and ignition be triggering on and off whilst cranking?  I can see my fuel pump change to ON when cranking and rpm increase to 180 rpm approx.   I can smell the fuel so I'm assuming some fuel is being injected.

 

2.  What is a good starting point for master fuel under fuel main?.  it was 5ms initially.  Stock injectors.

 

3.  Is there a way to change ref timing ? Or is this fixed ?  Currently on 10 deg fixed.  What does this affect?

 

4. Are there any settings in the software that prevents the engine from starting?  Like a protection setting ? 

 

Thanks in advance.

 

Photos below show state when key is in and on vs key is cranking and engine not firing up.

 

Thanks.

[Vipec Engine protection strategy? Oil pres / Fuel pres...]

Hi All,

I'm looking through the VIPEC software and can only find Limits which focus's on RPM, Speed or MAP related limits.

 

Is engine protection purely done here?

 

I'm assuming:

Set GP RPM Limit 1 or 2.

Set to advanced.

Select input to be used (vs RPM or other).

In my case it'll be AN Vx (oil pressure or fuel pressure).

Set rpm limit in the event of conditions being met.

 

Is this correct?

Am I only limited to two limits?

 

What other ways can I do this?

 

What about sensor fault conditions? Can I use an overall sensor fault to create a high level alarm?

By this I mean, define all sensor voltage related thresholds.. create 1 RPM limit for any sensor that goes out of range. Or is fault sensor under Analog inputs moreso related to faulty sensors and not threshold limits?

 

Any advice appreciated.

Thanks.

 

[Vipec V44 - Injector Dead Time - Axis locked?]

57 minutes ago, Confused said:

Not sure on the ViPEC, but in the G4+ you can set it to a 3d table to be able to adjust the axis breakpoints.

Thanks for that. I did notice that in 3D table mode with Vipec also.

I ended up making a tool in excel to calculate dead times at fixed voltages.  I think it'll do the job.

[Vipec V44 - Injector Dead Time - Axis locked?]

Hi There,

Is the injector dead time table axis locked for a reason?

My dead times have odd voltage reference numbers.  Otherwise I'd have to map it out on excel and try and develop a linear comparison to obtain the numbers that Vipec allow.  Let me know if there is a solution to update the axis values please.

 

Thanks.
