nice opti/pcm cure

i am sure quite a few people have been keeping up with this conversion however for those that have not,this conversion can eliminate alot of the problems with Lt1 tuning!
the Ls1 style PCM is extremely advanced compared to the Lt1 it proceses info much quicker and has a few more features that can be used by us namely:
key off fan control for up to 5 min after shut down
rpm capable above 7200 where ours start to get wacky
more controlled timing tables
no more opti weather you have had issues or not
coil on plug operation
you can also add 2-step control
i cannot wait to get my hands on this conversion,my daily driver and very possibly my track car may now stay with an Lt1

Only bad thing I see is you have to stick with a single roller timing chain. Will not work with a double roller. Otherwise.....will be a great upgrade for a lot of people!

I agree despite what others may tell you some people need a good double roller.
I talked with one well known tuner. He gave me the idea of running that ecm with a distibuter and batch fire injection cuts the cost way down looking for the peices to try it on my motor before I rip it back out of the car.So far 10.576 @ 128.64 on a 1.563 short time.

Still looks like a hassle... I'd rather run a setup like someone else mentioned in the Dual sync thread. (Without looking back I believe it was 9sec 6spd or something along those lines)

Depends on how the price pans out... if it's good then I'd get it... if not I'm sticking with working with DTS300zx and his EDIS-8/MSII setup
