Jamesy Posted August 21, 2009 Share Posted August 21, 2009 i have recently fitted a dual SBC.. ....im not entirely sure how it works but its set to 53 .... ...now usually that is 1.2 bar but occassionally it goes up to 1.23-1.25 bar. is that normal due to weather conditions???

jevansio Posted August 21, 2009 Share Posted August 21, 2009 Maybe this will help with setup http://www.rtec.ch/dsbc_manual.html Link to comment Share on other sites More sharing options...
Jamesy Posted August 22, 2009 Author Share Posted August 22, 2009 Thanx for the link that was interesting. I didnt even know there was a gain setting. But what i wanted to know was if its normal for my boost to change? The boost limit ia set to 1.25 and on 52 ratio its usually about 1.2 bar. However sometimes without touching the boost controller i might see 1.23-1.25 from it ...... Link to comment Share on other sites More sharing options...
Jamesy Posted August 23, 2009 Author Share Posted August 23, 2009 Anyone? Link to comment Share on other sites More sharing options...
DaveR Posted August 23, 2009 Share Posted August 23, 2009 Is it during gear changes? Boost can spike higher than the maximum limit on gear changes. Link to comment Share on other sites More sharing options...
nigelboyne Posted August 23, 2009 Share Posted August 23, 2009 my boost controller is set to 1.45 bar uk supra but have seen 1.57/1.6 bar as member said its spiking for fraction seconds Link to comment Share on other sites More sharing options...
Jamesy Posted August 23, 2009 Author Share Posted August 23, 2009 Ok cool. As it only shows the max boost achieved its currently showing 1.25. However when i reset it i'll usually see 1.2 - 1.22. Every now and then when i floor it it'll nudge up to 1.24 - 1.25. I just thought a b/controller sets the limit and thats it, but if this is normal then cool. Ive got the safety limit set to 1.25 anyway! Link to comment Share on other sites More sharing options...
nigelboyne Posted August 23, 2009 Share Posted August 23, 2009 keep an eye on the boost when temp drops Link to comment Share on other sites More sharing options...
Jamesy Posted August 23, 2009 Author Share Posted August 23, 2009 Does that make it run more boost then? Link to comment Share on other sites More sharing options...
nigelboyne Posted August 24, 2009 Share Posted August 24, 2009 i always get higher spike readings in cold weather .plus the car is a lot stronger in cooler weather Link to comment Share on other sites More sharing options...
Jamesy Posted August 26, 2009 Author Share Posted August 26, 2009 yeah i have realised im actually running about 1.15 bar but the occassional spike to 1.24 for a second which is why my peak bar shows the highest reading.... im happy now Link to comment Share on other sites More sharing options...
hadyn Posted August 26, 2009 Share Posted August 26, 2009 I thought one of the main benefits of an electronic boost controller is that it doesnt spike??? Link to comment Share on other sites More sharing options...
shima60 Posted August 26, 2009 Share Posted August 26, 2009 internal wastgates spike a bit more than external. this can't be helped no matter what boost controller you have although an electronic one can controll it better Link to comment Share on other sites More sharing options...
