Default N/A tuning ECU

I've just wrapped up my ECU to ship to Courtenay Autosport, they're gonna put a new fueling curve in it to suite the mods and increase the rev limit a bit, hopefully to 6900rpm. All being well, it'll be back in the car for the P.E. rolling road day.

I so want to do there ultralight flywheel in billet steel 275, so tempting. Better value than the Mantzel inlet manifold, 500 for an extra 8bhp .

So are you looking for a hp increase? How much you think you'll get w/ the remapping? AA new flywheel would be nice, BTW. :-?

Well I gone and done it, it's a superchip but not as we know it, the mapping is bespoke to suit the mods already made, hopefully they've got it right [hey, they chip 2 - 3 V6's a week , that's a lot of tuned Vectra's out there] I'm hoping at the next PE rolling road day to see that mid torque dip [around 3000] to be gone, i'm just about to install it. They said they haven't done much about increasing the rev limit [as it's 6600rpm] but the fueling carries on increasing closer to this limit allowing a little more peak, but not much, an extra 8bhp at best, hopefully some general driveability will be back from fitting those silly camshafts.

OK ... with this mod plus everything else you have done, I guestimate that you have to be in the 225-230hp range now Raggy (perhaps even higher ) ... you really have to change your location information to reflect that!
Especially with the "N/A DADDY" running across your avatar!


Way to go!

I think i'll give a conservative estimate of 205 to 210bhp, which would be nice, driven it this morning but not in a silly fashion, doesn't seem to have been detrimental. The rolling road will show the net result [but if its a hot sticky day the power output may be no better than the last time, which was a cold day]

I'll be towing with it next weekend I think, the 9000 isn't fully adapted yet [needs a different stabiliser bracket ]

Can you give me more info about what you've done? Is it just this ECU upgrade? Do you have a v6? Cost, if you don't mind me asking?

I'm a '96 vert 2.5 NA 4c owner, I'd like to learn what you've done.
