I think the rotor in my opti blew up and I was wondering if I buy the LTCC setup would I have to buy a new opti or could I just clean the broken rotor out and put it back together. I believe I am still getting a signal from the opti to the computer, so I don't see why I couldn't. But I figured I would ask you guys to be shore.


Thanks

 

As long as the optical eye is working you can use it for the ltcc setup... Check the coil for spark... If you have spark that means the eye is working... Just make sure to get the rotor peices are out of their and that you use some kind of spacers in place of the rotor other wise the screws will be to long... Also be sure to silicone the unit back together are the optical sensor will have a shorter life span...

 

twdz28,

I am getting spark at the coil. Thanks for the info.


Does any one know wether or not I can use any of the new gm vec's coils or do they have to be the ones from a F- body?

Thanks

 

Sounds like a bandaid to me. Even if you got the LTCC, you would still need to take the opti apart to clean all the broken pieces out. After doing all that work might as well throw in a new opti.. So either way the opti still has to come out.

 

yea, but then he could save the $$$ he would spend on a new opti and put it towards the ltcc.

this is a great question, i was wondering the same thing. when an opti "goes out" what is typically the problem, and would it still be usable for ltcc?

 

Like I said in my previous post if the Optical Eye in the Opti works the LTCC unit will work... The LTCC unit runs of the Optical Eye... To test if the eye works check for spark at the coil if you have spark the Optical Eye works... You said your rotor broke, when installing a LTCC unit you do not need the rotor in the Opti...

 

dude, if his rotor is BROKE, then that will lead to the optical sensor being broke as well that's the POINT

 

so are you telling me that if he takes the rotor completly out and cleans all the little pieces out of the opti that the LTCC set will not work if his optical eye is good???????????? You dont need a rotor for the LTCC set up to work....

 

Holley makes some... The ones from the LS1 work well... Also the 8 Liter truck... Just find some from a junk yard... I pick all eight up for $60.00...

 

If it were me I would replace the opti. You can buy 'em used off of some message board if you don't have the money to replace it with a new one. I've seen some slightly used ones on here before. I wouldnt want to be wondering about my opti messing up the LTCC.

The rotor has to be bolted down to hold the "optical eyes" or disks in place. I guess you could just bolt the two tiny torx screws down without the rotor, but I don't know how well that would hold the disks. It might not provide an even clamping force across the face of the disks.

Open up an Otpi and you'll see what I'm talking about.

 

what kind of spacer would you guys recommend using has anyone every used something from home depo?? Is anyone useing a spacer and what and where did you get it??

lol, yea that's what I was trying to say I thought you were trying to tell him that he didn't need to worry about taking his opti apart to clean all that $hit out.. I was like "huh"

 

Thanks for the in put guys.

I don't see why the eye in the opti would go bad if I clean the rotor out and find a spacer to put in there so it bolts up correctly.

Does any one have experience with this? Please chime in if so.


Thanks

 

to see what we are talking about you need to open the opti up... You need a T5 torx to get the cap off, if you do not have on use one of the screw form you throttle body plate, the head is the same size... Just use a set of lock pliers... When we say spacers its more like a set of washers to hold the optical wheel down... you can reuse the the screws that come out of it but you need to put some washers in it to make you for the rotor not being their...Ohterwise they will be to long and hit the backside.. Just make sure that the wheel is not hitting the eye and that everything is free when you spin it... Just open it up and you'll see what we are talking about...
