[Thunder extra sensors display on aim mxs light]

Hello Adam,

 

thanks i'll have a look when i get time.

 

[Thunder extra sensors display on aim mxs light]

I am running a race car with a g4 thunder ecu .

I have connect on it 3 more temp sensors gearbox and differentials.

I have a aim mxs light dash and setup it with the standard link can protocol.

Is it possible to send by can and display on the dash theses sensors temp?

Thanks for help

[G4+ thunder VQ35HR engine unstable rpm cranking]

no because i thought it was allready in the start map, i will check them

[G4+ thunder VQ35HR engine unstable rpm cranking]

another thing,

 

now the engine running , with the 4 cams sensors correctly setup, i've tried to make the vvt working and i have an cam error comming on both intake cams "cannot sync"

Enclose the log if you have any idea.

 

Thank fr your help

[G4+ thunder VQ35HR twin e-throttles]

Adam,

I've setup throttle1 manualy and the voltages when back in the right way.

The relays where of because of the motor dc% was at more than 90% 

 

[G4+ thunder VQ35HR engine unstable rpm cranking]

thanks, that's 142, the engine started !

[G4+ thunder VQ35HR twin e-throttles]

Hello,

The engine is using twin e-throttles, i've done the wiring as explain in the help files (see my quick diagram).

I've calibrated the APS and both e-throttles. throttle1 automatically, and throttle2 manually. 

When i leave the setup mode using run throttle mode to test them engine stop or under cranking, i have fault codes comming 70, 73, and 99.

When i go back in both throttles setup mode, i can see the throttles working fine following the aps.

Looking the online help, i've check the lines from relays to ecu (B5, D1) and Vbatt is present even when the fault code appears.

Aux 19 and 20 are not used

Thanks for your help

[G4+ thunder VQ35HR engine unstable rpm cranking]

Adam, Vaughan,

Thanks, i've done the correct wiring / setup as you said and now the engine run fine on crank but still don't start.

do i need to calibrate the trigger offest or is it allready setup?

Could it come from the e-throttles fault?

[G4+ thunder VQ35HR engine unstable rpm cranking]

Hello,

I've tried to start my vq35HR engine , but the rpm signal is unstable.

I've used the VQ35HR trigger setup mode, and i had to activate the pullup on both triggers 1 and 2 to get a signal.

I've wired the sensors as done as original, so: pin1:+5v, pin2: ground, pin3: ecu signal

I've used as trigger 2 the intake cam sensor bank 1, (passenger side).

Had you ever seen this problem?

Hanve you any idea for help?

Thanks

Antoine

[G4+ thunder no can com with aim mxs strada light dash]

Thanks that's was it

[G4+ thunder no can com with aim mxs strada light dash]

Thanks Adam, i try to change the ID number and let you know 

 

[G4+ thunder no can com with aim mxs strada light dash]

Hello, 

I need some help because after wiring and setup the can protocol between thunder ecu and aim mxs strada light dash, following the aim help file, the dash still not display ecu values.

I have the last firmware

I have connected directly on thunder ecu can+ on pin D24 and can- on pin D25

Does the thunder ecu as a 120ohm internal resistor between theses two pins?

thanks 

 

Antoine

 

 

[thunder ecu auxiliary output setup low side fan relay and driver switch]

Ok thank you for your reply,

Adamw, so i don't need any diode between the Aux pin and switch connected both to the realy trigger?

 

[thunder ecu auxiliary output setup low side fan relay and driver switch]

Hello,

Using a thunder ecu, i need to use 3 auxiliary outputs low side wired to 3 relay so switch on/off oils pumps.

-i have to use on/off switchs (connect to ground) as well to use the oils pumps directly. do i need to use diodes on between switch and aux output?

thanks

Hi Adam,

I try to get a oscilloscope.

I've made a log may be you can see something,

When the engine cut you see the error trigger growing.

Best regards

Hi Simon,

I've connect the ecu back from you on the car an now the outputs are working fine in "test mode" and "pwm test", i can hear the électrovalves working.

But now another problem, when i run the engine up to the rpm lockout (2000rpm) in " vvt  setup" the engine stop.

When the engine stop, i can see the in limits part of the screen, the "rpm limit on" and orange.

At the same time i can see the vvt target and position angles Moving. 

i use the vvt base map setup file "audi v8 4,2L"

Have you any idea of this problem?

Best regards

Antoine

[Crank trigger and cams sensors setup G4]

Ok Can you tell me where to send it and how to proceed?

I've check direcly the solenoids on a battery  and i can hear them clicking.

My Customer had made his own loom leaving all the unused wires  so i've took of all the unused pins from both connectors.

i've checked again the wiring:

Left solenoid on aux 2 pin 20 connector A

right solenoid  on aux 1 pin 21 connector A

I've tested the aux 1,2,3 and 4 with a test light (connected on the 12v on one side and aux to the other) with the "PWM test" and the "On test", and the aux outputs are still not working .

 any idea?

thank

 

[Crank trigger and cams sensors setup G4]

Hi Adam,

Back to work on this car, vvt are still not working, but this time i've check again the wiring witch is ok (12v on one side and connected to the aux on the other) .

The electrovalves does not work, are connected on aux 1 and 2 set to "vvt controllers" .

When i set the aux to "pwm test" 50hz Nothing happen i Don't ear them  working.

i've tried as well to connect them on aux 3 and 4 and same result.

DOes the engine has to run to test the auxiliary?

Have you any idea?

 

thanks

Hi Adam,

We've check the combinaison outputs and vvt solenoid, it's ok, but the vvt still not work.

I've check as well if the solenoids clicks and it's ok

I've put 20° in the vvt table and log the engine running.

One cam doesn't move and the other goes from 0° to 40° directly.

see the log file attached.

may be you'll see what's wrong.

Hi Scott,

After this long time the engine is running ok and nearly ready to be mapped on the dyno.

I still have a problem i can't solve, the 2 vvt cams are not working .

I use the trigger2 as cam sensor1 and DI2 as cam sensor 2.

When i run the engine, i can see cams positions but they don't follow the target.

I think i've done something wrong but i don't what.

I send you the starting map i use actualy, may be you will find what's wrong.

 

thanks for your help

Best regards

Hi Scott,

I try that and log it .

[Crank trigger and cams sensors setup G4]

Hi Scott,

I've made the test.

With the trigger offset setup at -80° there is only the 4 first coils of the firing order working (cylinders 1, 5, 4 and 8)

With the trigger offset setup at 280° there is only the 4 coils  last coils  of the firing order working (cylinders 6, 3, 7, and 2)

In attach files, the record the two tests with -80° and 280° offset, the engine start every time on 4 cylinders.

Thanks,

Antoine

Yes i have acces to an oscilloscope if needed.

I want to keep as well the vvt functional

For your trigger mode, remember i use as special 60-2 trigger Wheel on the timming belt side  so the trigger offset is different of the original audi one, but i try it .

i'll make a record of the engine start  hopfully this week end.

thanks

Antoine

[Crank trigger and cams sensors setup G4]

Hi Scott,

Here is the bas map done.

The coils have built in ignitos, all are working in test mode and i don't have trigger errors.

the 2 cams sensor triggers are the same, when i use the left cam sensor as trigger 2, i have the first 4 coils (in the ignition order) working.

When i use the right cam sensor as trigger 2, the 4 other coils are working.

I try to get a log of the starting quick, what do you mean by a trigger scope image? is there a function in the software or you a image taken from my scopmeter?

thanks

Antoine
