SCT Chip

[fst 5pto]

ok I had a tune done when I had nitrous. I had a switch installed to alt between two tunes. car seems like it doesn't have as much power so after doing a couple other things I figured I would check the timing. shoot the timing light and it looks like I'm only at 7-8. question: if I have a tune, will the timing read correctly with a light or is it all in the computer?

what othere things have you done you might need a reburn ,as far as i know a timing light should work

[fst 5pto]

All I have done is drag springs, control arms, and 4 wheel disc. Nothing to the motor. I dunno if maybe the switch somehow came out? I remember Ken saying if it pulled out it would go back to the nitrous tune, which is obviously less timing.

That shouldn't change your base timing. The timing is taken out, in the computer.

Did you pull out, the spout connector, when you put the light on it?

Yes I pulled out the spout connector. And what shouldn't change the base timing? When they burned the chip, they put two tunes. One for spray one for NA. There was a switch to alternate between the tunes. Ken told me that if the switch came out, it would default to the nitrous tune, which is less timing. Not sure if thats what you meant by "that shouldn't change your base timing?" Let me know exactly what you mean.

I'm going to check the timing on both tunes today and see if the timing changes. That may clear up something?

a friend of mine is having the same issue. He has been trying to reach Ken for the past 2 weeks or more and no return calls.

But will the timing change with a light if I switch between tunes? Or just internally in the computer?

[fst 5pto]

ok checked the timing and no difference between tunes. I put it on a number without a tune and it started idling rough. checked the timing there and it was the same. I guess the timing light doesn't work when you have a chip?

With my old sct chip. My base timing was 10 degrees with spout out. The chips timing is based off the engines 10 degrees.

If you have to pull the chip,set timing to 10 degrees and reinstall the chip.

I had it dyno tuned. does that make a difference? I thought they burn the chip with everything correct and it doesn't matter where the distributor is?

[347sc]

I did too at MD. we set mine at 10

[fst 5pto]

so pull the chip out and set the timing at ten? is it just a easy pull out?

[347sc]

Try it with it in first and go from there. Once you pull the spout that take all ecm timing control out of the picture.

ok thanls for the info. ill let you know how it goes

When you check the timing, with the spout connector unplugged, it removes the computers control. That is your base timing. I believe Ken uses 10* on all tunes. When you plug the connector in, THEN the computer takes control of timing. The default is set to the safest tune (retarded timing), to protect the motor.

Get the base timing set, get the switch fixed and you should be fine.

I dont think anything is wrong with the switch.... the reason I thought it was at first is because the timing wasnt changing with the timing light.

With the spout connector out, it reads about 7-8. Ill bump it to 10.

Thanks for all the info guys!

Why don't you try contacting Ken?
