2 x cps = +6* timing

[Talyn]

The one that I tried to move and bent a bit was an aftermarket. The one that I cut the wings off of was OEM. The sensor was dead but I kept the middle part. I will see if I can try to find it for dissection.

Maybe the renix ones move easier than the newer ones. I had the high-alt CKP on the 88 Eliminator.

Could be. I bought 2 high altitude Renix CPSs from the dealer as spares when I found out they were being discontinued.

you know you drive a jeep when... :laugh:

I bought a used SCT 9550 on ebay, and had my friend cook me up a few tunes. Right now I'm running around with +4 timing and 1300 rpm extended idle. we tried +6 but the crappy 87 octane we get out here in cali it was too knock prone.

What year are you reprogramming? Anything special in your programmer?

 

[Talyn]

There is a lot more you can do with the SCT than just idle, timing and fuel. Such as cruise control low speed, fan turn on temp, torque control removal, etc.

 

[sidewaysstarion]

There are MANY things you can do to these ECU's that you can't do with SCT. My friend happens to be very skilled with Jtec/sbec tuning and has been tuning vipers/magnum motors long before SCT ever showed up on the mopar scene.

 

[Talyn]

The SCT device can physically do all the stuff that the other guys can, but I am unsure if the standard SCT programming software supports it.

 

[CobraMarty]

So How do I get a SCT programmer with the supporting software installed on it so I can adjust/tune the stock ECU?

 

[Talyn]

Contact an SCT dealer and get their pricing on the unit and a tune. You won't be able to write your own tunes unless you become a dealer.

 

[DanMan2k06]

I dunno if it's been discussed earlier in the thread, but is there ANY advantage for this on a stock motor with stock fuel management?

 

[Talyn]

I see no reason why it wouldn't help a stock engine.

 

[CobraMarty]

What's the point if you can't write your own tunes and make your own adjustments. No 'canned' tune will work for all the possible combinations out there.

 

[Talyn]

You work with the person that is doing the program. No one said anything about a canned tune.

Does Kolak still reflash jeep ECUs?

 

[Talyn]

No he doesn't but [email protected] does a good job. Kolak didn't actually do the programming himself, but hooked up with a company that did it for him. That company sold their software and equipment and no longer does it.

this is renix fi is much better..... we have a knock sensor to pull out timing.
realize that you are only altering base ignition timing
the ecm adds/subtracts timing from there
