WetGTR Posted November 1, 2005 Share Posted November 1, 2005 Boost spike can come from 2 area's 1. Boost control unit 2. Boost creep - The wastegate is too small and there is not enough exhaust flow out. I think in your case, only 3 psi above stock, should be answer no.1 Link to comment https://www.sau.com.au/forums/topic/93175-the-22-boost-controller-spiking/#findComment-1681130 Share on other sites More sharing options...
benl1981 Posted November 1, 2005 Share Posted November 1, 2005 a 1 psi spike I wouldnt think is a real concern... what are you worried about? Link to comment https://www.sau.com.au/forums/topic/93175-the-22-boost-controller-spiking/#findComment-1681191 Share on other sites More sharing options...

predator Posted November 1, 2005 Share Posted November 1, 2005 lol - if you want 0 or closer to it, the only way is an ebc.. and spending more money than $22..

NateR31 Posted November 1, 2005 Author Share Posted November 1, 2005 a 1 psi spike I wouldnt think is a real concern... what are you worried about? <{POST_SNAPBACK}> because the car jolts when its spiking between 10 and 11psi ..... Its a steady 10psi all the way up, and jolts @ 6k but goes away at 6.200-7,500 this is on a rb25det aswell Link to comment https://www.sau.com.au/forums/topic/93175-the-22-boost-controller-spiking/#findComment-1681339 Share on other sites More sharing options...

benl1981 Posted November 1, 2005 Share Posted November 1, 2005 If it jolts then you are hitting ECU rich and retard i.e. if you have stock ECU. Wind back the boost 1 -2 psi and see how you go. A 1psi spike isnt going to cause the car to jolt Link to comment https://www.sau.com.au/forums/topic/93175-the-22-boost-controller-spiking/#findComment-1681466 Share on other sites More sharing options...

Oosh Posted November 2, 2005 Share Posted November 2, 2005 Most boost gauges are pretty poorly calibrated, chances are you're really running more than 10psi, spiking up just too high and hittingR&R as mentioned. Wind it back until it's okay, but if you want finer control, spend some real money on an EBC.

blackrb20silvia Posted November 2, 2005 Share Posted November 2, 2005 mine works fine was one of the first to get one have had no problems at all i run 18 psi no spike no drop off (if wastegates have anything to do with it i am running a 38mm externall gate) Link to comment https://www.sau.com.au/forums/topic/93175-the-22-boost-controller-spiking/#findComment-1685296 Share on other sites More sharing options...
benl1981 Posted November 2, 2005 Share Posted November 2, 2005 1 psi isnt that bad. I reckon he is hitting the ECU R&R Link to comment https://www.sau.com.au/forums/topic/93175-the-22-boost-controller-spiking/#findComment-1685318 Share on other sites More sharing options...
SimonR32 Posted November 2, 2005 Share Posted November 2, 2005 um im actually assuming that its still connected to the factory solenoid and its moving from the low boost setting to the high boost setting... if u know how to correctly set up a boost controller then manual ones can acutally work better than mechanical Link to comment https://www.sau.com.au/forums/topic/93175-the-22-boost-controller-spiking/#findComment-1685443 Share on other sites More sharing options...
benl1981 Posted November 2, 2005 Share Posted November 2, 2005 (edited) Well thats a point. The stock one spikes 2psi at 4400rpm anyway!! heheheh Edited November 2, 2005 by benl1981 Link to comment https://www.sau.com.au/forums/topic/93175-the-22-boost-controller-spiking/#findComment-1685450 Share on other sites More sharing options...
Cubes Posted November 2, 2005 Share Posted November 2, 2005 If your getting a spike at 6000rpm during accelerating them its not the boost controller. Its something else. The ball/spring type boost controller will only cause spikes when you initially jump on the throttle and it boosts up really quick, slightly overshooting the mark. The other time it will spike is when peak boost is made while accelerating from a low rpm. Allthough not as common or noticable as jumping on the throttle and have it instantly hit boost at higher rpm. I've had 3 types of manual boost controllers. The $22 boost controller, a ball/spring/bleeder and a simple bleeder all did the above. For $22 the manual boost controller being sold works just as good as the others being sold for $100 odd. A friend tried mine and said it was better than his GFB boost controller.

NateR31 Posted November 7, 2005 Author Share Posted November 7, 2005 ok it seems it wasnt spiking, it was missfiring hence the jolting, and it just happpend to happend when the needle went to 11psi, i fixed the missfire problem now it runs fine, and holds boost perfectly!
