**Vti-S JAZZ** · 13-07-2005 04:48 PM

If one installs a new filter and cat back exhaust do we need to "reset" or similar the computer so it acounts for the new system? or does it do this automaticly

any idea's?

Do a reset and it will take a few runs for it to be up to speed.

what mean by reset?

You reset the ECU by removing the negative pole on the battery for approx 1 hour. The ECU will the re-learn the closed loop program, and hopefully the car won't run lean.

hahahaha

Yes it works...saw it on the dyno

i'd say take it to the dyno, let them do it while tune it to the best too
but in the end of the day, you'd wanna get more mods before doing that kinda thing, it's not something you take your car to do every so often if you're not loaded

I'd like to know how you plan on dynotuning that on a Jazz, taking that the ECU wont let you alter Injector Duty Cycle.

if you disconnect the battery for an hour..you should reset your CVT and power windows aswell (if you have the cvt variant)

ok once its off for a hour or so, then do you drive it around the block at normal speed, or open it up? (WOT)

cheers

WOT man!!!!

Just give it a few hits to get up to speed.

It took about 4 or 5 runs on the dyno before it had sorted everything out for me.

And don't forget to reset the driver side wiondow as the auto down/up function won't be working.
