Geezabloke Posted May 5, 2003 Share Posted May 5, 2003 Blitz DSBC on UK spec, does the gain setting help with Spool times and how does it work? If so what is the safe/Optimum setting for this? as the instruction manual was a little unclear! Presently set to a gain of 7, with the 1st channel @ 67% this gives around 1.8bar peak. Thanks for any help..... :flame Dev Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted May 5, 2003 Share Posted May 5, 2003 1.8!!! - Don't like your turbo's or engine much do you:eek: Quote Link to comment Share on other sites More sharing options...
Dragonball Posted May 5, 2003 Share Posted May 5, 2003 M8 - check out the product settings threads sub section under technical! Cheers Paul Quote Link to comment Share on other sites More sharing options...
Geezabloke Posted May 5, 2003 Author Share Posted May 5, 2003 Matt Where did ya get 1.8bar from mate, the peak hold goes to 1.18 max and the limit is set to 1.2........ Quote Link to comment Share on other sites More sharing options...
Geezabloke Posted May 5, 2003 Author Share Posted May 5, 2003 Matt sorry mate, just seen the error, should read 1.18bar. Once again A THOUSAND APOLOGISE............ Quote Link to comment Share on other sites More sharing options...
Guest Martin F Posted May 5, 2003 Share Posted May 5, 2003 Do a search on DSBC and as Paul says check out the product settings at the top of the technical section. This has been discussed quite a few times before. Quote Link to comment Share on other sites More sharing options...

Steve W Posted May 5, 2003 Share Posted May 5, 2003 I assume the Boost Controller only actual makes a difference AFTER the point at which the wastegate would have normal opened ? ? UP to that point the controller can't actually DO anything ? ? SO, the Controller only affects MAXIMUM boost level, NOT spool-up or boost BELOW that level ? ? It only TEEs into the wastegate pipe, doesn't it ? ? [and that's how the cheapo 'bleeder' works too ? ? just bleeds the pressure off the wastegate operating pipe ? ? ] FatS.

Adam Kindness Posted May 5, 2003 Share Posted May 5, 2003 its the rate function that affects the speed at which boost comes in...... gain is just how far it opens i have my rate to 10 and max channel4 setting to 60% giving 1.4bar channel1 is 5% and gives 1.0bar Quote Link to comment Share on other sites More sharing options...
THOR Racing Posted May 5, 2003 Share Posted May 5, 2003 UP to that point the controller can't actually DO anything ? ? SO, the Controller only affects MAXIMUM boost level, NOT spool-up or boost BELOW that level ? ? Not really. The way most are plummed in is in the pipe from the turbo bleed port and the top of the wastegate actuator. The secondary port on the wastegate actuator is normally blocked (capped) or the VSV unplugged (which amounts to the same thing) The secondary port is there to provide a sharper response from the wastegate valve opening. It bleeds air to atmos' and only shuts at a level of +ve boost. This shudden blocking of the bleed means that any boost from the turbo will now suddenly exert a force upon the wastegate actuator diaphram, which snaps open and subsequently so does the wastegate valve. By blocking this off pressure bled from the turbo is exerted on the wastegate actuator all the time and gradually opens the wastegate. So slowing down boost build up, as some is being bled all the time, as soon as boost starts to build high enough to start to open the wastegate valve. Might only be a tiny affect but nevertheless, the very action of fitting an aftermarket electronic boost controller like this will have this type of affect.

Steve W Posted May 5, 2003 Share Posted May 5, 2003 SO, the Boost Controller fitment gets rid of the 'slow bleed' to the wastegate ? so, increases boost a tiny bit BEFORE maximum boost ? [just tryin' to get me head round the benifits of the boost controller - if it only increases the boost when already at maximum then I'm not really interested - if there's an increase BEFORE the wastegate point, then that's different] Quote Link to comment Share on other sites More sharing options...
Dragonball Posted May 5, 2003 Share Posted May 5, 2003 On the SBC-ID it was my (albeit probably flawed) impression that the two seetings were as follows GAIN = Rate of boost response SET = Rate of Boost increase Where each number represents the increase over stock = ie 11 = 111% of stock Therefore 10 gain and 25 Set Equates to a 10% increase in speed of the turbo coming on line and 25% increase in the output Hence why they recommend only a 10-15 setting on the GAIN figure otherwise you get serious spiking Is this total crap?

Geezabloke Posted May 5, 2003 Author Share Posted May 5, 2003 Ive now set as follows; Gain set to 10 Ratio set to 67 Limit set to 1.25 & -10 This has showed a peak of 1.19 on seperate test drives. It takes off after 4000rpm, very slight loss changing up to third then back of the seat again till the brakes are needed. The car is a UK auto with standard internals, judging from what ive seen on the BBS this is probably a little conservative for a UK. :flame Dev Quote Link to comment Share on other sites More sharing options...
