Will the TII ecu work on an NA?

ErixHvn · 04-21-06, 12:57 PM

Have an S4 NA that I'm trying to supercharge. Yeah, I know I'll probably get flamed for this but I need to know if the TII ECU would work on the NA w/ minor wiring mods. MAP sensor, Knock sensor, that sort of thing. Just asking coz if it does, I might actually use the TII ECU with an RTEK V2.0 for the project.

Anyone ever do this ecu swap? How did it run? How hard was the wiring?

Here's a quote from Hailers on another thread:http://www.rx7club.com/showthread.ph...=timing+retard

"A turbo ECU is plug and play with S4 as long as you use a turbo boost/pressure sensor with it. I've driven my 86 n/a like that for grins, for some time.

EDIT: OOPS. Read some of the thread. A turbo'd n/a. Get a turboII ECU, boost sensor and afm with 550 injectors all the way around. I wouldn't buy a RTEK until you make sure you can get what you have running decent."

--------------------------------------------------------------------------------
Seeing as how this statement wasn't contradicted by anyone on that particular thread. I would like to be able to use the Rtek7 V2.0 if my NA ecu proves inadequate for the job for this project. So is it true then? S4 NA and TII ecu's plug and play with the addition of the pressure sensor and TII AFM?

Would somebody be so kind as to confirm this before I got out and blow an engine unnecessarily? Thanks

The ECU/injectors/AFM and boost sensor should be run as a set; ie if
you want to run a TII ECU, use the TII boost, AFM and 550 injectors.
The NA wiring has minor differences:
- no knock sensor (not terrbily useful anyways)
- no "dual speed" fuel pump control. Shouldn't be a problem as the
NA fuel pump sees +12v all the time.
- you should disconnect the wire to pin 3D. Its an input on the NA ECU
and an output on the TII ECU (for the dual speed fuel pump control)

If you leave the Rtek seetings to stock, it will run as stock.

Was thinking of this option of the TII w/ an Rtek for this project. My SC attempt. It's to be decided between this setup and Megasquirt II. Your confirmation was very much appreciated.

I too am wanting to supercharge my n/a and was thinking of a full race computer. or something like that. I have to do alot more research on the deal but I don't know were to begin. I have no idea what I am getting into but I think that when I am done with the car it will be a mind blower! hows ur SC project going?
