Possibly a shorted wire.. that resistor can take some pretty hefty current usually. You might want to check that before you replace it and go for a drive again.

The other connection wire is +, coming from EFI relay and 10A fuse. Possibly it was a short circuit sometimes, as I found the wires have been repaired by previous owner.
It seems I was driving my car for several years with out tvis working properly Smile

The ECU is in electronic shop at the moment for part replacement and test. I hope it was only the fired resistor causing the problem.

Fun is not the straight line!

PLEASE HELP!
The resistor is so damaged that I cannot read the resistance in ohms Banging head
I need help. Can somebody check the resistance value of the R515 resistor in Ohms?

Big thanks!

I measured3,91 ohms. probably you need a 4ohm nominal resistance. good luck!

Good news! Hurray!

ECU is now OK! A few broken parts has been replaced. TVIS is now working properly. After first run I have noticed that BTDC has to be rechecked. Now everything is working perfectly. The car is flying Thumbs up!

Thanks man! I put the resistor as you said. The guy at the electronic workshop told me that any resistor up to 8 ohms will work as they are here just as precaution.

Thumbs up!

Since i didnt find a 3.9 ohm resistor. I put 2 10 ohms resistor i n parallel so know u have 5 ohms. And know tvis working.Hope this helps someone...

A new question:

Until i buyed my car, always had a problem in hight RPM...from 5000RPM the engine don't push like should. As my knee is much better, i started to do any things in the car. Today i was looking the vacuum-T-VIS conections and i saw this

[Image: AEU86 AE86 - my tvis doesnt work...]

Then i consulted the workshop manual and i saw this connections scheme

[Image: AEU86 AE86 - my tvis doesnt work...]

Huh
I think the connections are wrong, not? my car is zenki '84 and the manual is may '87, but i think connections are the same, not?

Looking the oldeskewltoy's pic....i'm confused because i'm seeing other tube that my engine hasn't it

Anybody know the zenki scheme?? is like the manual?

EDIT (10:31 19/02/12) I just change the tubes position and the same, the engien continues pigeon pea at hight revs Crying Let's search a electrical problem
