G'day

Today i pulled out the tfi dizzy and put a normal vacume advance dizzy back in.

Hooray, i finally have a stable idle and the car is now much more drivable. However i still have the afr all over the place :evil:

Now i think that the controller is the problem. I've changed all the settings ...

G'day

So where have i gone wrong then?

I used the instructions on the tfi page and i cant seam to get it to work.

I haven't got the ego correction turned on at all. The spark output from the ecu is definitly the problem, its just fixing it that i cant work out.

I dont suppose that this is a similar problem to mine.

Are you running a v3 board, ms-2 and trying to control a tfi ignition modual?

Cheers

G'day

Ive found a similar thing but mines isn't behaving nicely.

I have an erratic 02 reading all the time. It jumps from rich to lean all the time. I think that it is the ecu sending dodgy signals to the tfi modual.

When the spout is disconnected the car idles fine, when the spout is connected ...

G'day

Thanks for that.
Is that the same for the spike on the spout output or just for the injectors.

I have a v3 board, ms-2, latest code, tfi and pwm idle valve.

After having alot of trouble with getting my car to run properly I had run through all the options i thought i had. I spoke to a friend i have met that is in the elctronics game and he thought that it would be good to put an ...

G'day

I'll give that a go. What happens if it doesn't hold steady at 10* at different rpms? Where do i turn next?

I know when i had the timing light on it the other day it was jumping all over the place, but my spark table was all over the place as well.

My car seams to run between 17* at idle to ...

G'day

No i'm not convinced that the spark is good. The reason i say this is that i cant tune out a cough and splutter when you first touch the throttle. I can drive the car just be nursing it along.

How do you tell if the spark is not doing what its supposed to do.

G'day

Anyone got any ideas.
