Idiots guide to Performance CHIPS

[Guy_H]

man, I will have to find my "Archive" box - we did all those back in 99' & 2000.

Are you 1.8T fellows eligible for vintage registration now?

Your a funny bugger aren't ya!

I'm very keen to see these as I'll wack mine on a dyno shortly. I've done a bit since the chip (kinda everything bar bigger turbo) so it will be nice to have something I can use as a ball park point to go from.

hahahha..good one.... I think you need to find your new bifocals to be able to read them....hhahhahaa!!!!

Do you mean flapper mod from exhaust gate?

Yeah. According to dyno runs the guys did on Vortex, even when the exhaust flap is given the open signal it is not actually opening up all the way. Hence by bypassing the flap (via ecu switch, clamp or disconnecting the vacuum hose) you get power gains throughout the entire rev range as the flap will be fully opened. I know the US model was slightly different so it might not hold true for ours, but who cares it sounds awesome.

This is a very true statement - As for plug in chips or set flashes they are designed for one car in mind - the stock item eg polo 1.8Gti T stock. Its not designed in line with other minor or major mods that have been carried out. As these mods like intakes and exhaust on modern cars really can dissapoint you with gains unlike 10 years ago, due to the high level of software detecting anything from the norm and therefore returns the system back to default as close as possible. This is so until you do infact start doing electronic mods. IMO chips are good but the best way to do it is live on a dyno - i know it costs lots more money but you are seeing exactly what the engine is doing and what it needs at the right time and can be adjusted accordingly. You can also play with the AF ratio with interceptors but you have to be carefull you dont get a full load lean out and take the corner out of a valve or piston.
Anyway i still think the mass produced chips are good just remember they are no way personally tailored but you must pay for what you get.

ok, i thought i would shed some light on the chipping and maybe even the R32 200kw goal.

Ok as for chipping, i drive a chipped GTI daily, it has a chiptuning chip in it. I find it smooth but most power up top with higher redline it makes 121kw ATW (car has 2inch stainless straight thru Exhaust With Remus Rear muffler). I use to run a Superchip in my car that only netted 118.8kw (same as before but with 2.5 DP) (standard it made 96kw ATW) But power was way more smooth and power band was lower in the rev range and lower redline. That superchip chip is now in my girlfriends GTI it makes 130kw ATW (standard it made 102kw ATW), but is rather abit faster than mine.

As for the R32 200kw goal. By doing Cams exhaust and Chip will net you around the goals you are after. If you can get headers that will be a very nice combo. Talk to Hitman his R32 currently runs exhaust and Cams and make 157kw ATW.

My Vr6 before my mk4 GTi, from Standard it made 102.2kw ATW, i deconed the airbox and new aftermarket panel filter, did a Remus rear box and removed Cat and centre Resonator, same dyno, similar weather it then produced 112.9kw ATW.

All Giac chips are tested with stock car and are also run with various exhausts / intakes from vendor suppliers and are tested on the dyno before they are released .

This is so until you do infact start doing electronic mods. IMO chips are good but the best way to do it is live on a dyno - i know it costs lots more money but you are seeing exactly what the engine is doing and what it needs at the right time and can be adjusted accordingly.

This sometimes can work against you , if you have a weak engine then you are tuning based upon having hardware that isnt up to scratch .

You can also play with the AF ratio with interceptors but you have to be carefull you dont get a full load lean out and take the corner out of a valve or piston.

I have a bored and stroked 1.8T running S4 Maf 580cc injectors @ 5bar with a high flowed gt28 still running a chip . Custom chips are available but you have to pay extra .

WTF I got 114 kw ATW with cams, minor porting, CAI and 2.5" exhaust and Chip, WTF going on there
