Recommended Posts

Hello 

 

today i purchased 6 toyota yaris coils and installed it with the correct wiring .  

I tried to start the engine  .

it failed to start.

ignition setup is correct .

i did an ignition test , everything seems to be working correcty.

i did a trigger calibration.

Firing order is correct

NB : the engine was starting fine on wasted spark 

Thank you in advance

With my vvti 2jz running yaris coils direct fire I ran with the Trigger mode set to Toyota 1JZ V VTi, in the calibrate screen I had the trigger offset as 205deg

The Trigger 2 vvti offset was 170 ATDC

Hello

Thank you all for your replies

The engine started today after correcting the firing order

The coiills where set in the wrong order.

My bad

But the engine sound like a lawn mower ? 

The firirng order is set in the following order:

1 5 3 6 2 4       coil 1 to spark  1.  coil 2 to spark 5.  coil 3 to spark 3 . coil 4 to spark 6  . coil 5 to spark 2 and 6 to spark 4 

Same wiring for the injectors

Ill upload my file

 

Thank you in advance

you've got the coils wired incorrectly.  Wire them:

IGN1 to Coil 1

IGN2 to Coil 2

IGN3 to Coil 3

 IGN4 to coil 4

IGN5 to Coil 5

IGN6 to coil 6

Your firing order table is correct

from the help file:

When wiring an ignition system using direct spark, the firing order of the engine is not important as it will be entered into the ECU via Vi-PEC Tuning Software Tuning Software.

Ignition Drive 1 must be wired to cylinder 1 coil, Ignition Drive 2 to cylinder 2, 3 to 3, etc.

Same goes for the injectors:

The firing order of the engine is NOT important at the wiring stage as the firing order will be entered into the ECU via Vi-PEC Tuning Software Tuning Software.  Wire each cylinder to its corresponding injector drive number (wire cylinder 1 injector to injector drive 1, 2 to 2, 3 to 3 etc...).

Set the 'Injection Mode' to 'Sequential' when using this configuration.

Hi zilvia444,

You need to terminate the ignition and injector outputs as  1 to  cyl 1,  2 to cyl  2,  3 to cyl 3, 4 to cyl 4, 5 to cyl 5, 6 to cyl 6 etc.

Then the firing order should be set as 1, 5, 3, 6, 2, 4,

If you have wired the outputs as 1 to cyl  1 , 2 to cyl  5, 3 to cyl 3, 4 to cyl 6, 5 to cyl 2,  6 to cyl 4

Then the software firing order will be set as 1, 2, 3, 4, 5, 6.

Please remove the sparkplugs and disconnect the Trigger 1 or set the fuel master to 0.

Crank the engine to get rid of any raw fuel sitting on the pistons, also the sparkplugs are best replaced or at least cleaned, before trying to start again.

With the firing order being incorrect there will be wet sparkplugs.

Regards

Dave.

Hi zilvia444,

Then the firing order should be set as 1, 5, 3, 6, 2, 4,

If you have wired them the way you have the software firing order will be 1, 2, 3, 4, 5, 6.

Then the software firing order will be set as 1, 2, 3, 4, 5, 6.

Hi zilvia44,

firstly you have two faults with your setup.

One is the Engine Coolant Temp sensor at 5 volts.

The other is the TPS at o volts or shorted to ground.

Both of these errors need to be rectified, especially the ECT as your rev limiters are based off ECT

Your Fuel and Ignition tables are also altered via the ECT trim tables etc.

The TPS needs the 0 volt issue rectified and you then must carry out a TPS calibration.

Your ignition main tables has very strange settings in the high vacuum areas.

I have modified your ignition table to a more respectable base table.

Please rectify these issues and remove and clean the plugs.

Download my file to your ECU and see how you go.

hello i did all the above

the engine isn't starting 

do you think the problem is in the trigger setup ?

Thank you for your help i really appreciate it .

the fuel and ignition tables are still untouched

i got this base file from the link base maps library

i only changed the injectors and ignition mode + tps ,map , ECT    and TRIGGERS.

The engine bay is  still incomplete .

there is no radiator nor intercooler ..

my goal for now is to start the engine successfully  .

Thank you in advance .

In your map, the trigger mode is set to a 4cyl 2nz...  You need to change that to 'Toyota 1JZ V VTi', then set the trigger offset to 205deg in the calibrate page

The Trigger 2 vvti offset needs to be set to 170 ATDC
