You won't be using any LT1 stuff unless you have installed the LT1 Optispark dist on front of your GEN 1 so you will be using stock TPI ECM / wiring with custom tune
or buying aftermarket computer setup
The stock computer has no idea (or concerns )about what intake you have on your engine

this is stuped but can i do the opti stuff and how much of a pan is it to run a lt1 ecu and all my 92 gauges still work?? and the tpi ecu stuff will it be more nicer to a bigger cam?? bc theres no tpi unit any more

The computer doesn't CARE what intake you have ; all you need is a proper custom tune for it.
Plenty on here running a TPI computer with a HSR / MR /SR or single plane aftermarket intake


Only the speedo is connected to the computer ; gauges work independent

Anything is possible if you throw enough $$$$ and time at it

If you really want to spend $$$ , swap to a LS1 computer that has better support from tuners

Is exactly the same as a LT1 intake swap

Did you drill a hole in the LT1 intake for a reg dist?
If so you install the dist / sensors / wiring from your GEN I engine onto the new setup

92camarorv6

wel i got thinking and i would like to see if i can fit the lt1 opti and all on a gen one so i can run the newer somewhat more up to date lt1 ecu/pcm so i can get way from chip's

If it could be done easily someone would have done it by now
You would need a LT1 front timing cover to mount the Opti and I suspect it would take a lot of mods to get that to fit the front of a GEN I

If all you are wanting is no chips , buy one of these

and tune your '730 TPI computer straight from your laptop , even while you drive

o snap im learning lol now i have a ? have you use this ? so it kinda turns it into a obd 2 ecu ?? will the tune be flashed when i turn the car off im going to go over and read up on this now thank you so much for the info

vetteoz

The Ostrich takes the place of the stock memcal as far as holding the engine tune
The tune is stored on the Ostrich unit, you can leave it in the car permanently and just hook your laptop up to make instant tune changes as required
You can take the unit out of the car , sit it on your kitchen table and adjust the tune from your computer without it even being connected to the car
You can take the unit out of the car, put it in your bedroom for 6 months and it will be the same.
It is just a re-flashable unit that is very convenient and easy to use

Do a search for Ostrich
Plenty of posts about it

i thank you alot vettoz i see they have lt1 stuff to i could you that on my pops 93 z38 maybe?

The Ostrich works on any computer that has a removable memcal ( chip ) ; before '94 LT1

What you would do is buy one , tune a car , when you are happy with the tune burn that tune onto a chip to install permanently in that car ( need another G1 chip adapter )
then use the Ostrich to tune a 2nd or 3rd car .Unless you need real time tuning in two cars at the same time?

This does everything in one unit
http://www.moates.net/apu1-autoprom-...b-version.html

this is just a chip burner
http://www.moates.net/burn2-flash-n-...rogrammer.html

With any setup you also need one of these adapters to connect to the ostrich cable to the computer socket and also to put a fresh chip into the computer
after you have burnt the final tune on it
This adapter has 2 blank chips

bare bones adapter ( for use with the Ostrich )

that is very cool thank you for your time sir i have alot of reading and learning to do

your just using the modded lt1 heads? theres a write up somewhere on it. just search lt1 swap. dont believe you need a hole drilled for a dizzy but with the tech available to us now why not go coil per cylinder? the 411 ls1 pcm swap { which a link was given earlier} handles a lot and is more user friendly. if your only using the heads your stock tpi harness and pcm would work but benefit from a tune greatly.

He has moved on ,
He only wanted the LT1 electronics for the flash tune function ;with a Moates Ostrich he can perform the same on his stock TPI ECM
Real time tuning as he drives

Where would you mount the dist on a stock LT1 intake?

92camarorv6

hay vettoz i picked up a lt1 intake to day well its off a l99 is that any bad intake's that i cant use ??? casting # is 6310 and on the top it had a w 2

92camarorv6

fireburdluvr85

mr. vette, the way i understood it he was just converting stock lt1 heads for sbc use. even with an lt1 intake converted, u can use the 411 pcm with coil per cylinder. you dont need to use a dizzy in that case. its just another option on the table for the OP.

92camarorv6

firebird dude that's like 3g's that's more then what the t56 ill cost

fireburdluvr85

never a mention of budget

not that expensive with used parts. i got my 411 swap for around $350. if i wanna go coil per cylinder ill just add the wiring and junkyard coil packs. spareecm.com does a base tune cheap. then of course the killer to the whole, the efi connection 24x wheel. of course i made my own harness. only adding this for future readers to not shy away from newer tech. hell i almost didnt til i stumbled onto a post that outlined cost associated and since i want the 4l60e/ 4l80e capability it made sense to me. just so my words dont get cut and pasted against me, its only an option available to us. mr. vette just offered another tried and true option that may be more in tuned to ur needs.

im posting this from over on my ls1tech, ok here how i want to build my motor i got a later 350 roller block HD 4 bolt mains its out of a suburban so its got a forged crank (stock gm),stock truck low cpr pistons,i got a set of modded lt1 heads for a gen one sbc i will do some port work to them and i got a lt1 intake (its off a l99) that will have port work done bye me to i want to build the motor for a supercharger down the road tranny if i can find one in a good price rang will be a lt1 t56 (i have hurd bad things about the ls1 t56) and a beefy 10 bolt , i have most of the chassy work done now ,i want to keep my a/c this is a street car wil be driven every day the only thing is the cross flow can i just to the back with one head going to the other?? i may be posting this over on tgo two this is going in a 1992 chvey camaro rs right now its a v6 that's worked over some but im bored with that now

vetteoz

iTrader: (13)

Are you talking about the steam line between the LT1 heads?

92camarorv6

yes what im thinking is i can linke the two heads together and make it like a cross flow ???

vetteoz

iTrader: (13)

Sorry , forgot you are using a GEN I block , not a reverse flow GEN II LT1 block
Just plug the holes , not need with the normal coolant flow that your engine will have

92camarorv6

so i dont need a cross over on the back??

I wouldn't think so as the gen 1 only uses the front. If I were to do this swap I'd either A. Do what the pics have and run a remote thermostat on the front or B. Run a Single plane EFI and use early LT1 heads and weld in a tube for the coolant to go through. Either way it's a sound swap if you're willing to do the work.
