Zetec Ignition Timing, Settings and Table

[McNugget]

Hi there,

I searched for a while and noticed that there were many different opinions on this topic, so I would like to collect some and conclude the right one out of it.

Here we go: I heard that with a Ford Zetec-E 16V and the standard EDIS4 ignition driver using a 36-1 wheel in connection with an installed VR-sensor I have to set the Trigger Angle to 0°.
But then I read that the VR-sensor is installed 72° BTDC, others say 60° and even others say 90° BTDC.

Whats right?

I thought about the following: When I can set the ignition driver in MS to EDIS4 does it a calculation for itself that we have to set the Trigger Angle to 0°? But from where should MS know that we are talking about a Ford Zetec? It actually cannot. So why do I have to set the Trigger Angle to 0° with EDIS4?

I talked to a tuner last week. He's always using DTA ECUs and he has to set the Trigger Angle to 72° on Ford Zetec engines in Escort and Fiesta and others.

Asad, another guy with a GSXR 750 TB - like me - mounted, said at first he set the Trigger Angle to 60° but he noticed that he never gets full power. So he set the it to 0° and now the engine runs a lot better.
Yesterday I went on highway to tune my VE-table but I never really get above 114 mph. Actually the engine gets much louder but the torque felt down rapidly with an AFR value of 13.4 - 12.8. Without MS and without the motorcycle TB of the GSXR the car runs about 127 mph with much less db!

So, I don't trust my spark table. The VE table seems to be ok now. I have a WB lambda and the values are good.

Can someone please help me? I would love to get some spark tables from similar engines with at kpa range up to 108 or something like that.
And would love even more to learn some more basics about the Trigger Angle 'cause thats really making me crazy and I affraid to melt my pistons.

Thank you for reading

Timo

ps. I hope to get my spark table attached in a minute...

It's the EDIS module that does the calculation for the 90deg BTDC.
The EDIS receives the missing tooth pulse and "counts" the angular movement to TDC. It then outputs the signal to MS at TDC so your offset should be zero.
Thats how I understand it anyway.

My configuration:
- Zetec 1.8 (RQB) EDIS4
- MS-II PCB V3 Firmware 2.35
- Innovate LC1
- Trigger offset: 4° (checked with timing ligth)

Best way is to double check the trigger offset by a timing light.

sevenDriver.
Is there any chance of you posting either a screen shot of your IGN settings or your complete .msq file please I would like to compare my setup with yours as you are running the same basic hardware as me and the exact same software on a very similar engine.
You can send it to my e-mail address if you don't want to post it on here.
I'll pm it to you if needed.
regards

I use a patched firmware (I have change the IDLE-PWM frequency). The IDLE-PWM settings will may be not be usefull for your car.

My tuning is not finished but this configuration is a good starting point for fine tuning.

I would still like to have a look at your ignition settings page..
I haven't even tried to get the PWM Fidle working yet.

Hey thank you very much for your answer!

The 0° - 4° makes sense if the EDIS uses the camshaft sensor for reading the TDC. Then I would be able to set the offset to zero degree.

sevenDriver, could you please upload a .vex file of your spark table, too? That you be cool, cause I use MS1 and most of the .msq files are not compatible to other versions of MegaTune.

Thank you very much!

Hi again, I tried to extract sevenDrivers spark table manually from the msq file. So it should look like the pic below.

Do you think 24 degree is too much for full throttle? Because I'm not sure if my knock sensor is correctly calibrated. It shows a couple of knocks above 3100 rpm. At higher loads even more knock. I attached the datalog, too.

greets,
Timo

I have never try to use more ignition advance on WOT.
