Lads,

I have a list for the engine ECU's....

S1 = Blue - Red - Blue ~ No knock sensor

S2 = pre 1987, Blue - Red - White ~ No knock sensor

S2 = 1987 Onwards, Blue - Red - Black ~ With knock sensor

S2 = 1990 Onwards, Hearts & Diamonds ~ With knock sensor

Which i belive to be correct, would anyone have the list for the fuel ECU's?

The one i have has a blue label and i've seen them with green labels too.

Curious what go with what?

 

Thats correct

Blue label is S1 ECU (all) and Green is S2 (all)

Thanks mate

 

what does the knock sensor do then,ive got blue-red-black ecu and hav heard they rnt as good as the earlier ecus

 

TBH mate, i don't know.

Hopefully one of the Rs boy's maybe able to help ya

 

Knock sensor was added to later cars, but its prone to giving problems. It's supossed to retard the ignition if detonation is detected, but it's mounted in a stupid place, and tends to alter the igntion depending on what colur boxers ur wearing, and the postion of the stars.

 

so would it be worth trying 2 get hold of a chipped ecu from an early s2 then

 

billy i told u about the fuel ecus weeks ago about but u dont take me word for it do u

 

Just use a chipped S1 ECU..... job done

cheers

Steve

 

Alex zvh cabrio, That was a week ago mate, i cant remember what i done yesterday

I needed it in text lol

flashpoint, Yeah well thats what i need

 

The fuel ecu is specific to the loom

 

Turbosystems, In what way?

 

series 2 loom series 2 fuel box
series 1 loom series one fuel box
However the looms can be altered to suit the fuel box

 

Not alot

 

The loom is different for the fuel ecu, in the way the TPS works.

To modify the loom, you need to earth the TPS through the ECU, as on an s2 it earths to the body. I've done this on mine, as it totally removes the fuel rev limit - the omex soley controlls the rev limit.

 

Well thats pretty self explanitary

So..

S1 = Blue
S2 = Green

 

rick could you expand as even I don't understand what you are saying lol
You need to be more specific with the fuel box you are using and the wiring mod .
series 1 tps is live switching series 2 is earth switching
series one fuel box does not have a rev limiter series 2 does

 

lol, sorry was a bit vague.

I use s1 ecu on s2 so there is no rev limit. I modded the s2 loom so that it was live switching.
