hey ppls... jus a question.. i went to the wreckers the other day n pinched a computer from a vl calais... on the computer it says 5 something and on the one i had in my vl originally said 3a or sumthin.. i changed them around.. n still runs nicely except my idling is a bit rougher.. does any one know what the difference is between the 2? help much appreciated.. thx

anyone? lol?

prob represents the diff between engine displacement ie. 3L and 5L and auto or manual... just a guess...

VL 5.0L wasnt EFI so it didnt have a computer, may represent the diff between manual and auto tho, not sure.

I think the calais had a different computer and loom to the lesser models due to all the electrics and such, but it's just a guess.

hmmmm... lotsa guesses... it still runs fine.. just idling is a bit rougher.. i thought it was the difference between the 5 l and 3 l too but i guess it cant be now...
maybe this ones a pentium 5, n the other was a pentium 3? lol

no idea...

did u try putting the old one back in? just to see if it ran rough still??
could have been just by chance that it wanted to start running rough when you changed them!

5 and the 3 in my mind would have something to do with the amount of electric's that it has to run.. as calais came with the alarms etc... i dont think executives did.

i dunno, im guessing like the rest.

lol.. mines a berlina.. umm it doesnt run rough... jus a lil rougher at idling...
maybe i'll ask holden..

I think a new ECU can take a while to adjust itself to another car, give it time, maybe speed up the idle
