LT5 swap into 89MY L98?

[Corvettes White]

If you want, If you have the aility, If it would even make a difference in response to the above comment. The removable chip that was used in 1989 Z's, I have two versions that you may copy if you wish.

I was following until the above... Looks like you are saying in the first sentence that the CCM controls the LCD and then in the second you are saying the LCD is handled (controlled) by the ECM??

What am I missing?

you caught a typo.. ( thanks)

it should read:

the CCM controlled the LCD on the cluster. so any function of that LCD on 90-96 was handled by the CCM Not the ECM

I talked with bill a few months back and he said he used the new computer and just pinned out the connectors to the right outputs. He lost his fuel computations and that was it...

So the ECM feeds parts of the CCM and the CCM controls the LCD?

Yes..

The CCM gets data from the ECM for the sensor display on the LCD panel (92-95). The fuel gauge also goes directly to the CCM then to the LCD

in the 89, I think he could use the 90 ECM and not have too many issues.. the only thing that would not work would be Fuel mileage, but I know that the code for the Instant fuel etc can be modded in the 1990 BIN to work with the older dash, I know someone who has done it, so if he got the LT5 running int he 89 and everything else functioning then the BIN could be changed to show the fuel calcs as well

I have 90 Dash with harness and CCM still installed, you would need to track down the Dash cluster but I have the dash cover, the skeleton with harness, All the vents, the Info center and almost all the ZR-1 specific wiring harnesses except an engine harness

I have the body harness the headlight harness all of it.

It's kinda what you want to do and if you really want the 89 dash.
Since you can bypass the power key with the chip its not like you have to incorporate the valet key.

and yes, dead serious on swapping LT5 into my 89. i realize the easy route is to pick up a real Z... but there's a certain sentiment to 22 year old low-mileage vette ordered from the factory.

I owned my 84 for 24 years. For sometime, I strongly considered installing an LSx motor in it. I went ahead and bought a ZR-1. Sentiment went out the window. I really don't think about the 84 much.

I think with all the money and labor you'll put into it you can buy a complete ZR-1 the prices of ZR-1's in the gutter today.

If you decide to do it i have a complete A/C parts for ZR-1/LT5
