I was looking into getting a tuneable ecu. I know I can do chips but since I have an 85 most places wont burn chips and would rather just get rid of it altogether and tune with a laptop.

Heard DFI is good and know I could always go LS1cpu but that is pretty expensive.

Also what all can I keep with my dash?
I figured I would go aftermarket gauge cluster anyway but just wondering

thanks for the help.

There is also EFI Connection.

They do the LS1 ECU conversion for old school Gen 1s.

I would rather do that than use an over the counter units. The aftermarket doesn't have the drivability advantages that OEM has.

SO ls1 computer would be your choice over a DFI or F.A.S.T.?

especially if you intend to drive on the street.

There is always the risk that emission tests could run you into problems, the LS1 solution would work best...

Where do you live?

I would consider this a good option:

Im in south texas. No emmsions standards at all.

Haltech makes a plug & play system for the older C4

FAST is nice since a lot of tuners are used to it.

Then there's upgrading to a later C4 unit.

From what I have seen I like the FAST and LS1.

Which parts of my gauge cluster will be lost with either option?

Later c4 would be more convenient but still has chips.

Later dashes need an aftermarket ECU piggybacked in to remain functional.

Early dashes loose things like MPG

Supercomp Digi gauge cluster will be done at the same time. I will have a 0 miles car lol

the later C4 does NOT use chips... from 1994-96, there is an EPROM.

EFI Connection offers and LS1 conversion for the LT1/4 ignition. I just don't know how well it would work in a C4 vs, say, an f-body.

thought u mean 86-91

Wouldnt that need an opti?
Sounds better to do the LS1 or FAST XFI

XFI looks very nice and not to expensive.
I havent priced out the whole LS1 system but looks very pricy

For my '95, I just hook up a laptop and reflash like the LSX guys.
