Dubcharged

Gazza, Leew: I shall not be broken 8) Chris: Soon mate, perhaps you could mail me your specs? G60: I far as I know, he can't. Just give your specs to sam/Danny and they'll happily sort you out. Oh yeah, I'll be at inters with my Rallye and a vid of No Lag A/F vs regular chip A/F, so come and say hello!

Chris: We're working on some maps for the supercharged VR6. Also on the standard Vr6 lump although not sure if that'll be worth doing yet since not much can be gained with a chip alone.

I love you guys!! :D Gazza: Even if you tell the ecu to go to map before WOT switch engages, it will still lag! I understand fully that you guys want to know how its been done. However i'm sure you can understand my position too. Since we're the ONLY people to have developed G60 maps to this stage and removed Lag, its something that many other tuners are itching to copy! :x C'mon guys, give me a break and just enjoy the fruits of our labour! :D :D

I'll be there too, will have a stand in the clubs section with some maps and other goodies! I'll have my Rallye there and a video of the No Lag code in action! Come over and say hello :D

LOL :lol: Leew, the ecu doesn't necessarily rely on the WOT switch to switch to map value, it will go to map value after a preset boost level anyway (hence the vac/boost line from throttle body to ecu) We've brought this value lower. As soon as you tell the ecu (WOT switch or boost level) to go to map value, it will have the lag regardless. Like I said this was programmed by VW. We brought out the WOT feature AFTER the gen 1 No Lag code. :wink: We still use closed loop mode, you have to otherwise driveability and economy would be terrible! The No Lag feature isn't a simple piece of code or instruction, its integrated into the map as a whole. All you need to know is that it works flawlessly and its great :D C'mon, stop torturing yourself and just try it out! :)

Try disconnecting the ISV and see if it makes a difference. (You'll have to adjust the idle screw)

Hi Sandy With a 65, you should get around 15-16 psi depending on the condition of the charger and how well its been ported. I'm getting 15psi with a cam (you'll get more without the cam) and using red top injectors to supply the necessary fuelling. I have a good set of maps for the red top injectors and 65/62mm pullies. I have the injectors too :D

nope, its a lot more unique than that. Obviously I cant go into detail about it but what i can say is that our maps aren't your normal chips tweaked from stock! :D 8) :D

You'll find that the Digi-Lag remains with the canister removed. Interesting theory though! :D Neil (Volkspeed) is doing a 20v engine with the G60 ECu as control brain. He gets digi-lag! No carbon canister there! Its not the engine, its the ECU. VW put this into the ECU on purpose to improve emission/mpg. My 8v GTi has it too. For stock boosted motors this lag isn't much of a problem since at low boost level, lean out doesn't do too much. However, when you go 68mm or smaller, it becomes much more substantial since boost build up is quicker. Digi Lag is based on a time domain, it doesnt see how quick you build boost, it just lags at a preset period regardless. :? With our map you can actually remove the WOT switch and fuelling will still work fine! So people with old and perishing WOT switches need not worry. We actually advise this for turbo set ups since it'll make the turbo spool up 500rpm quicker. :D

At times like this i wish I had my site ready :( OK, Digi-Lag is an inherent feature/fault in the Digi-1 and digi-2 ECU's, ie G60 and Polo G40. I'm currently testing to see if my digi 8v gti does it too. Under normal driving, the ecu reads off the lambda and trims the fuel to keep the average at 14.7:1 (stoichiometric). In real time with an A/F gauge you can see this as the A/F cycles up and down where the ECU is working to trim the fuel. This is closed loop mode. When you floor it (WOT) you do hit the full throttle switch BUT the ecu continues to cycle the mixture for a second or so (not always the same time) before it hits the map value. So enrichment is "lagged" and this happens again as soon as you take your foot off, change gear and floor it again! :? So you can imagine the effect this has: You're coasting along, a Type R comes up beside you, you drop a gear and FLOOR IT, boost shoots to 1 bar (68 pulley) BUT your fuelling is cycling still :shock: SO under full boost your fuelling is going as lean as 16:1, sometimes worse :shock: So your initial throttle response is letting you down and the Type R edges away, a second or so later your enrichment kicks in and the car starts to gain on the Type R :twisted: Now you gotta change gear, you do so and the bullshit lag kicks in again :oops: Its not just under WOT that we've eliminated Digi-Lag, you all know that under 70-80% throttle, you can build good boost. Here your ECU is cycling still BUT we've mapped it so under normal driving, if you get boost (8psi) then the ecu will stop cycling and giv your poor pistons the fuelling. I can talk about it all day, but you have to really try it for yourself to see the difference in response, not to mention the safety factor of lean out under boost which has been eliminated. :D Phew (By the way, this code has been copyrighted under international law)

Advancing the ignition timing is a matter of fine tuning for the individual needs of your motor. Depending on where it is now, you may find that you can obtain more aggression by advancing to the optimum (before pinking). :D

Must be a cross flow head with a turbo strapped to it :D Where art thou Blade?

280bhp??!! With the G-lader on the pre-cross flow 8v head? I'd love to see how he's done that! :shock: ipk: Love the wheels 8)

Which wire did you connect the grey signal wire from the gauge to?

http://www.snstuning.com/removale.htm Or just give me a call and i'll guide you through it since its from me anyway :D

The fuel rating in the US is calculated with a different method, they use the average between RON (Research Octane number) and MON (Motor Octane Number). Their 92 is equivalent to our 95RON They have better than 92 over there, you can get 103 unleaded which would be 107RON here!!!! Conclusion = Our petrol sucks :( I have run out of A/F gauges for the moment, will have anbother batch in soon.

Quaiffe 6 speed box :D Indestructable charger

You can use the intercooler too but the pressure drop by using both might be more than desirable. All depends on the chargecooler you're using. Do you have any details for the cooler?

My pleasure! :D Although I am already giving loads back to the G60 owners by helping them achieve a higher level of accelerating bliss :D :lol:

Word of advice, I did this a while ago and noticed a very loud whistle whilst driving part throttle. This was due to blocking off the bigger pipe(*) coming out of the side of the throttle body under the inlet boost hose. Basically when the bypass butterfly is open the air passes over the hole for the pipe (*) and as mine was blocked very close to the throttle body it caused a whistle. Imagine blowing over an empty bottle. :? SO, I've put a longer hose there and blocked that off so the whistle has been eliminated. You could even leave this open as its downstream of the btpass butterfly. :)

There you go, worth every penny. Great forum, great cars, great peeps :D

Did you measure your 0-60??

This is an inetersting point. The way the ISV bleeds boost is controlled by the ECU which ultimately comes down to the map. I have experienced the stock chip and a performance chip made here "no names mentioned" which allow the ISV to vent 0.2 bar boost after 1 bar pressure is reached. I saw this repeatedly. This code has been eliminated by some German tuners and our maps. Apparently, the US stock G60 chip doesn't have this code anyway. Apart from this, a worn ISV will leak boost regardless.

Very true Campaign, better late than never though eh?
