GTI APR chip mod, and clutch upgrade

[McDub]

thanks for the info guys. i spoke to both derek and seb, both were very helpful.
seb says they've only got the stage 1 program atm, not the stage 1+, but that's cool because i'd be happier running 16psi rather than 18... i think


so yeah i think i'm gonna go with seb (bug racer) and get the Unitronic, for two reasons, one being that it's almost half the price of the APR, and secondly, i don't have to wait for a couple of days while the computer gets shipped off for soldering a part onto it, as is the case with APR.



anyone here got the unitronic program on their MKIV?

[McDub]

so anyone done the unitronic? i'm getting it done this fri hopefully.

Unitronic is fairly new in Australia, but has a good following in the US apparently.

Mate, talk to Seb about the clutch he will set you straight and probably has plenty of first hand experience of what both types will offer.

I haven't replaced my stock clutch yet but from what I understand the 14lbs version will give you faster wind up due to the lower rotational mass, while that sounds great the downside is that because of the lower mass often it can make a chattering sound at idle that you may not approve of. The trick is apparently some will do it and others won't.

The 20.5 lbs feels closer to the stock clutch, from what I understand this one eliminates any chattering at idle due to the extra mass maintaining some load on the teeth of the flywheel gear and stopping the backlash chatter.

Both offer more holding power than stock. When I get around to doing the clutch I'll go with the 20.5 pounder as I don't want to take the punt that my car might start making the random chattering noises at idle just after I've spent all that money on a new piece of kit.

well i got the unitronic stage 1 ecu reflash done tonight
love the new power, as people say, it's like getting a new car!
flooring it in first is crazy now, front wheels just border on the limit of their traction through the entire rev range, can feel it ripping into the road

gets my vote

and of course met seb, real good guy, and really helpfull.
he works long hours too, which is real handy. and he's moved to the street parallel to his previous joint (had me confused for a good 20 minutes). 51 mandoon, girraween, NSW is the new adress.

oh and regarding the clutch, seb does the 14lbs flywheel, and says he doesn't have problems with it. i forgot to ask more about that topic though, dammit!
