anyone have these figures?

What do others with GTS 25t have as there Gear judge values?

I've found some information on a number of site on the web and thought they may be helpfull to others as they were to me...... TUNING: Basic tuning will take a few hours, but fine tuning all the parameter will take a while. The tuning instructions in the manual leave a lot to be desired... the translation is fairly poor. Read and re-read this section, about the third time you read it, it does start making sense. And if it seems that a word is missing in a sentence... it IS! I guess the translator didnt know the English word. So I attempt to explain what each of the parameters does along with how to set it. Also, the boost is displayed in Kg/cm^2... the conversion to PSI is 14.22:1 NOT 14.5 or 14.7 or anything else. STEP 1) System parameter setup - All in 'Etc.' menu Car Select: Cyl=6 Spd=2 Thr=Arrow pointing up Sensor Sel: Relative1 (leave as default) Gear judge: This is how the unit knows what gear you are in. mine at the moment is set as follows: 1st=125 2nd=070 3rd=049 4th=035 5th=025 Read directions to check. Grph Scale: These are units for the graphing view modes only. Bs=2.0kg/cm^2 Ne=7000rpm Sp=180km/h (good to 112mph) STEP 2) Mode [A] setup Boost/Duty Values which control boost Set boost at 1.10 (can be anything, but 9psi seems like a safe start) Set duty cycle at 20% Scramble: I did not use this feature Ne-Point These are the RPM points at which boost/duty cycle can be individually set - RPM's less than the lowest point use the settings for the lowest point, same for higher than highest point.(It works...) I use: 3000,3500,4000,4500,5000,5500,6000,6500 F/B speed This is the 'boost control sampling frequency' - i.e. how often the controller checks the boost and corrects it. The basic idea is, if boost consistently overshoots, increase number; if boost oscillates, decrease number. Learn-gear This turns 'self-learn' mode on/off, per gear. With this turned on, I found that the unit kept dialing my transition spike back IN (eliminating spike is later). I turned learn-mode OFF in all gear, this is 'X' for all gears. But learn mode may work better in your car... experiment with it. Start-Duty This controls initial spiking - i.e. quick no-throttle to full-throttle at 3K. This feature reduces the max boost a little, when going from negative pressure to boost... so it has the desired affect of reducing the initial spike, but not impacting sustained boost. Controlling initial spike is covered later, for now if can be set to 0% for all gears. It helped me to undersatnd a few things Dean

ALSD......You would not think so it the wet.....damp even i think it has but i realy dont know?

So am I right thinking that if, i can work out how to actually tell it to boost only to say 0.6 bar in first then more in second gear, it would be a form of launch control? Dean

'Gear specific boost control' Has anyone got one and knows how to set this gear specific boost control? the instructions may as well be in japaneese... :aroused: I'm assuming that this 'gear specific boost control' means thats in each gear the boost can be set to a diferant value, thus avoiding wheel spin and excessive boost in say first gear? or have i got the wrong end of the stick?? I've set my max boost settings and got a nice stable 1.2 bar, but now i want to see if i can get more control, for example the rev's section, and gear section.. Would love some real basic help if any one can..... Thankyou Dean

Thanks Chaps, I've got the spring as loose as it can be, and it does lift a little when the gate is closed after light boosting and a little more when revved hard, so it seams to work ok, but im more worried about damaging my brand new turbo, the O.E.M valve even though it leaks is so fast at letting the pressure out that i get no flutter at all?? as you know they are just a spring and plunger inside and a few vac pipes off the top simplicity to the max so, just a few more squirts of wd40 to get it running smoother i guess. Thanks again for the reasurance Dean

Has no-one got a blitz bov on a gts 25t, to see if theirs is the same? Dean

The install looks realy great... but How do you change the bulbs? have you got pull out pannels etc?? Thanks Dean

My O.E.M. blow off valve started to leak after a t4 turbo install and 1.2 bar of AVCR boost , no wonder realy Ive fitted a Blitz Blow off valve (to atmosphere) blanked off the recirc and removed the O.E.M valve. Question. Is the blitz valve supposed to be slower at reacting to the waste gate being closed? Mine seems quite slow in comparison to the O.E.M one, as this when not atached to the recirc pipe, realy is an open/closed blow off, almost like a switch on or off. This blitz is a bit slugish realy, ive wd40'd it and its all nice and smooth, this is making the blades in the turbo chop a bit, untill the valve is open and then its not fully open unless its realy getting some stick. Any ideas, is this ok? normal? Thanks Dean
