IMO there is no point to developing a unit to work with the LTCC b/c youd be essentially building another opti... why reinvent the wheel? Once you take the spark out of an optispark, all you have is a spinning optical sensor which is not subjected to the same faults as a fully functioning opti. If you get the opti wet while running the LTCC.. you will not be left stranded as before since there is no spark delivered from the opti anymore... only high/low resolution signals for the PCM.

 

your right...

Like I said, I don't care about the LTCC since I'm never going to use one anyway. The reason I came up with this design is to simplify the method of obtaining a cam sensor signal for using an aftermarket sequential unit rather than messing with drilling out intake manifolds to use a hard to get dist. plug from MSD that might work with some modifications. Or not having to send off your timing cover to get modded to accept a sensor that has to be custom fit, has no adjustability, and requires modding a timing gear to accept a magnetic trigger.

My design works with no mods whatsoever to the engine, bolts into place just like the stock Opti does, has 360* of adjustability that can be done in seconds, couldnt care less if it ever got wet, which it will not after the billet cover is finished. Will work with pretty much any aftermarket engine management available, costs very very little, has no maintnance, and anybody with a lathe, time, and patience can do it themselves.
In this case, I didnt "reinvent the wheel", I just tweaked it

props to you , man. I wish I had the resources....

 

Hey.. this could be use to adapt the ls1 pcm to the lt1 engine...

and to where do i have to send a "crapped" out opti?

 

What's the purpose? What's to be gained?

 

2 things...

its a better pcm than the lt1 pcm... faster processor nad the likes.. it still controls tranny and addresses the high stall problem for the lt1s...

2) the ls1 pcm has been modified to accept a 2 bar map sensor correctly by some australian guys... so i guess it would be a nice idea to do this retro fit for some of the boosted guys lt1s as it will retain many stock feautures and no need for 2 pcms would still use 8 coils and the such... and no opti is needed.

 

I'm using a stock LT1 PCM (speed density)...with a chip burned to utilize a GN 2 Bar Map sensor. I run the LTCC setup on a blown 93 Z28.

 

who burned the chip and what changes did they do?? was it code changed or simple recalibration?

 

PCMforless....I think its a scaling change on the calibration. He fabbed up an eaton for his 93 lt1 and since there's no MAF on the speed density PCM ....the extra range of the MAP is the only way to go.

 

Exactly what i will do.. i will eliminate the maf anyways.. i always wanted to keep it...

i think that if this doesn't work i will go with gen 7 dfi... hope i can adapt the 8 coils to it.

 

any updates on this??? i can't get the pictures anymore

 

There you go!
I transfered the pics to the new website so they now do work again...

 

Ok im trying to adapt an ls1 pcm... how much you want for something like that?

 

I'd like to know also. It seems that by using an ls1 computer you would be able to rev past 7200rpm as well. Correct?

 

I am not familiar with the LS1 PCM, so I can't help you on that.
What I came up with was strictly for easy bolt on installation of a fully adjustable cam sensor that uses an inductive pickup like all aftermarket engine management systems use.
I'm sure you would be able to use this setup for most anything else that uses individual coil packs as well, although you may need to either change the sensor or the pickup itself to include more teeth. Both would be very easy to do.
