Pabs Posted April 4, 2008 Share Posted April 4, 2008 Hey all, Unfortunately I'm totally new to the world of boost controllers, and after reading the manual for the Blitz SBC i-colour unit I'm kinda lost. My main concern is that I was driving the other day put my foot down a bit and the boost controller read a peak of 1.4bar!!!?! The warning level is set to 1.15bar, but I don't know how/why this was breached. The car has a 1.2bar CW restrictor ring in. Could this reading just be an anomoly (sp?) or something? I think it must be something to do with gain, peak, and auto/manu modes on the controller? What sort of settings should I have for a Jspec BPU'd TT? Has anyone got any info for a numpty like me to understand? I've searched on here and found lots of information, but I can't make out which one is the right one. Last thing I want to do is to boost higher than 1.15bar. Thanks! Link to comment Share on other sites More sharing options...
Sheefa Posted April 4, 2008 Share Posted April 4, 2008 Check this out Pabs as the settings shoud be similar. http://www.mkivsupra.net/vbb/showthread.php?t=4547&highlight=SBC-II I had the SBC-II BC and often it peaked occasionally at 1.35bar. You'll need to tone down your set/gain levels slightly. It's hit and miss really and you need to test them out. Do you have 4 channels where you can customise and select each as per the older SBCs? It doesn't matter if you have a 1.2 ring in or not. Occassionally the boost levels can spike and the BC is used to increase boost over the 1.2 bar ring so it is easily possible that the levels you've inputted are too high.

Sheefa Posted April 4, 2008 Share Posted April 4, 2008 Try the following mate: CH1 SET=75 Gain=26 CH2 SET=70 Gain=26 CH3 SET=60 Gain=26 CH4 SET=57 Gain=26 SET = Boost Pressure/level Gain = Boost Resonse/Spool up These were used by Sharpie I believe although I used the following for a J-spec BPU with Hybrids and was finally getting a good 1.2 bar Channel 1: SET 20 GAIN 10 Channel 2: SET 25 GAIN 10 Channel 3: SET 35 GAIN 15 Channel 4: SET 60 GAIN 25 Link to comment Share on other sites More sharing options...
Pabs Posted April 4, 2008 Author Share Posted April 4, 2008 Thanks mate. I've not changed any settings from when Paul E had the car - and it's only ever had a value BIGGER than 1.15 this once, everywhen else it's been well under. It seems to have 4 channels - but I haven't ventured into many of the settings yet. I tried to rotate the screen by 90degrees, but the vertical mode seems to chop off a lot of the image because the screen is wider than high.

Pabs Posted April 4, 2008 Author Share Posted April 4, 2008 *numpty mode on* Am I right in assuming then that you can flick between channels to get different boost settings - say one for daily drive, one for fast driving etc? If so, I'm gonna have to figure out how lol - as I might be running the higher one of the lot lol... EDIT: It would appear that this is the case, but is it a manual task to change between them?

Sheefa Posted April 4, 2008 Share Posted April 4, 2008 Well mate, Paul E has posted his settings in that first thread link I posted above so check those out. I reckon you just hit a one-off spike mate. Do you have a manual boost gauge too? I had my BC and a mechanical Boost Gauge just to make sure the readings were on par with one another. Take it out for another good run and try each channel and see what happens. If you peak above 1.2 bar, come off WOT immediately of course Greg Link to comment Share on other sites More sharing options...

Correct. I used Channel 1-2 for a typical drive which still gave increased boost/response to 1.1 bar and channel 4 for a real good blast which was 1.2 bar although it peaked at 1.3/1.35 sometimes too I had hybrids so the occasional peak wasn't too much of an issue for me, mainly the duty cycle. It's not difficult to change between them mate. You should only have to push one of the arrow buttons, one sec I'll take a look......... Link to comment Share on other sites More sharing options...
Pabs Posted April 4, 2008 Author Share Posted April 4, 2008 tis ok - it looks like you press the "encoder" in the middle, and can channel select from there. I don't have a boost gauge other than this controller - the screen is quite small to see while driving, but going to move it to digital display rather than analogue dial so I can see the peak figures more clearly. I'll try looking at the settings for the 4 channels tomorrow perhaps. I know Paul E's settings on that thread are probably from his previous Supra as I don't think he had this supra for that long.. i know he had a white one before. I don't want to keep badgering the chap anyway - he's probably annoyed with the numerous emailed questions I keep asking him - thought I'd try and understand things myself Link to comment Share on other sites More sharing options...

Pabs Posted April 4, 2008 Author Share Posted April 4, 2008 Oh, and whats the limiter and scramble function? I can assume that limter means limiting.... lol... but I thought that was the point of setting a peak value. Unless that is only for a warning level, and not actual limit?

Also, try using the record function to monitor and playback things. Gives you a good 3-4 mins I think of recording boost activity for review. I think it was just a one off mate and a little cold perhaps when it happened? Don't worry. The occassional spike is fine as long as you're not running it excessively at 1.3 bar Link to comment Share on other sites More sharing options...

I'm pretty sure the Limiter is the Peak warning level mate, sure it was on mine. It won't stop the boost reaching a higher level though, it will just flag up a warning. Ignore scramble function, i'm sure this is to do with Speed Controller which I take it you don't have? Link to comment Share on other sites More sharing options...
Pabs Posted April 4, 2008 Author Share Posted April 4, 2008 lol - f00k knows mate - still trying to work out what's on this car lol! Scramble mode seems to give high boost settings for 3 seconds or something, but whatever it does I'm not interested in it for now. I think first things first i'll check the 4 channels and their settings tomorrow, and compare them with what you posted above. I'm sure it was on ch1 and the peak was definately at 1.2bar on the screen, but like you said, it's hard to see on the analogue screen which it was on when I got it - wasn't brave enough to touch it to change to a different view until today when i sat in it in my garage and had a look! I really appreciate your help mate - thanks! Link to comment Share on other sites More sharing options...
Sheefa Posted April 4, 2008 Share Posted April 4, 2008 You're welcome bud. Just bear in mind that one Supra's BC settings will differ from anothers, even if they are both stocker j-specs. You need to tinker with it a little to get a happy medium. You're a bit far away from me, but if you need a hand I'm sure we can work something out and I could pop over Greg Link to comment Share on other sites More sharing options...
Pabs Posted April 4, 2008 Author Share Posted April 4, 2008 now that's club spirit - thanks mate! I'm sure I'll sort it out, but thanks for the offer. I expect it's just me being scared of things at the moment - only had the car 1 week today, and just noticed I've hit 2,000 posts too And almost 2yrs to the day of being on here! lol Anyway, yeh - I'm sure Paul has the settings right for the car, and I'm not doubting the way he has set the car up at all - I was just a bit worried when I saw high figures and didn't know anything about how to set the car up!

I'm sure Paul won't mind you giving him a quick call mate to check if he's experienced a spike in boost before. But as I say, give it a run yourself in each channel and if you hit high boost, just reduce the set level. Link to comment Share on other sites More sharing options...
Pabs Posted April 4, 2008 Author Share Posted April 4, 2008 which do you usually decrease? The SET or the gain? SET, right? (the boost value over stock settings) Link to comment Share on other sites More sharing options...
Pabs Posted April 7, 2008 Author Share Posted April 7, 2008 Can someone help with something that is really bugging me...? I've checked the settings, and currently they are: CH1 Set=42, Gain=15, Limiter=55, Scramble=5 CH2 Set=40, Gain=15, Limiter=55, Scramble=5 CH3 Set=20, Gain=10, Limiter=55, Scramble=5 CH4 Set=15, Gain=5, Limiter=55, Scramble=5. The one thing that is really bugging me, is in meter mode (dial), next to the dial is the controlling channel (in my case CH1) and then the set value next to it. I am certain that the value next to it should be the controlling figure - ie 1.15bar (the warning limit) - and in the manual in all pictures/diagrams it shows the same thing (1.2 bar) Why is mine still showing the SET figure "ratio" and not the 1.15 figure I'd expect? I'm sure this is what I saw when Paul had the car... so I must have done something silly? Ta I understand that all channels should be in manu mode for the supra, as the auto doesn't work well. I am certain I haven't changed any settings (but might have adjusted a setting somewhere accidentally) Link to comment Share on other sites More sharing options...
Dragonball Posted April 7, 2008 Share Posted April 7, 2008 Call me m8! Preferably when sitting in the car - if you have seen 1.2 it will be due to the cold air and the dial in SET figures just need tweaking down slightly - maybe a couple of points on channel 1 The other figures were only for use when in programme mode DONT go as high as the other figures quoted above - and it stays in MAN mode ALWAYS (or you will see boost spikes!) The gain can be upped slightly - this controls the responsiveness - but again can cause spikes. Link to comment Share on other sites More sharing options...
Pabs Posted April 7, 2008 Author Share Posted April 7, 2008 it's ok mate - I might call you soon tho! I've only had 1 peak of about 1.4 something i think, but was at night and very cold. I'm sat in the garage in the car with engine off trying to learn how to use these toys you had installed lol.... Do the settings above sound like what you had set? Or have I c*cked something up somewhere? The one thing that is bugging me is above - why the controlling value next to the centre of the dial does not read 1.15bar like I'm sure I saw with you, but it says "42" instead (the SET value)....

Pabs Posted April 7, 2008 Author Share Posted April 7, 2008 I'm going to have to take the car out for a drive and find out what happens I suppose - but why the controlling value doesn't change I don't know. Can't see this affecting anything though, just annoying. Link to comment Share on other sites More sharing options...
Dragonball Posted April 7, 2008 Share Posted April 7, 2008 i The one thing that is bugging me is above - why the controlling value next to the centre of the dial does not read 1.15bar like I'm sure I saw with you, but it says "42" instead (the SET value).... The 42 is correct - it tells you the 'set' value in the centre - always been there You can change it to peak hold - check out the instructions The 1.15 bar that I showed you is on the graphs inside - there are 3 diffeerent ones you can use to check on conditions etc What the hell - take it out anyway!

Pabs Posted April 7, 2008 Author Share Posted April 7, 2008 hehe don't tempt me mate - love driving the car Perhaps it's the peak hold then.. the instructions definately have it as CH1 and then 1.20, and I can't only get the SET figure in there... but i'll investigate.... As you seem a whizz with these things.. what exactly does the scramble mode do? I think I understand the limiter - in the fact that when you hit the warning level it stops it increasing a lot over this figure - am I right in assuming scramble gives XXX seconds of non-limited boost?

Dragonball Posted April 7, 2008 Share Posted April 7, 2008 As you seem a whizz with these things.. what exactly does the scramble mode do? quote] Gives you the scramble boost figure for as many seconds as set for This is not unlimited - again you set this to a lvel you want...
