Sheefa Posted February 22, 2007 Share Posted February 22, 2007 OK guys, See this thread for a bit of info: http://www.mkivsupra.net/vbb/showthread.php?t=100599 I have the Blitz SBC-ID I model installed and this was fitted by Phoenix in Watford, who I assume, are pretty good, in May 2006. However, despite raising the Set and Gain functions, and making sure each Channel is on Mnaual NOT Auto mode, I still can't get above 0.76 bar!! The video attached is working on Channel 4 which has a SET of 60 and a GAIN of 25. As you can see, it's going nowhere and I was doing over 6 at the time it hit 74, past 4,000rpm too. http://www.youtube.com/watch?v=xkdbiCt0vwc - watch from the 55 second mark! For info, my settings are as follows (again all in Manual mode): Channel 1: SET 20 GAIN 10 Channel 2: SET 25 GAIN 10 Channel 3: SET 35 GAIN 15 Channel 4: SET 60 GAIN 25 Does anyone have a clue what could be wrong? I'm worried I might not be BPU after all! Surely, with a full decat, BC, better fuel pump and hybrids I should be seeing well above the 1bar mark?? I don't want to up the set/gain further just in case I do something adverse to the engine! Help guys! No idea what to check. Thanks, Greg Quote Link to comment Share on other sites More sharing options...
markjodrell Posted February 22, 2007 Share Posted February 22, 2007 Have you not asked Chris Wilson about this? The boost you are getting is std I thought 0.7 -0.8 bar of boost. Quote Link to comment Share on other sites More sharing options...
terribleturner Posted February 22, 2007 Share Posted February 22, 2007 Is it a brand new controller or 2nd hand?? Have you checked for any leaks?? Does it spool up slower when coming on boost?? What boost do you hit with the controler turned off?? Quote Link to comment Share on other sites More sharing options...
Sheefa Posted February 22, 2007 Author Share Posted February 22, 2007 Mark, Haven't asked Chris yet as only found this out for sure today. He checked the fuelling of my car etc using his Motec and all seemed fine, but don't know about boost. I did mention that to my recollection I've never seen over 0.8 (0.76 to be precise) bar before. It's a S/H unit guys, fitted by Phoneix only in May 206 - so new when purchased then!! Haven't checked for any leaks Terrible, the car is running very smoothly and only just had it back from CWs. New FMIC, new turbo soelnoids, rad etc. I haven''t done a run with the BC off yet though. Will it show the boost level still then? I could also confirm using the mechanial boost gauge. That's a point. There's a mechanical boost gauge (a Greddy one) in my Glovebox which I've disconnected the bosing from, would this affect my Boosting as I thought it was just another feed to a gauge?

markjodrell Posted February 22, 2007 Share Posted February 22, 2007 Greg , if you mean you had a feed going to two boost guages and you took one guage off and didnt block it off you would be loosing the vacuum , if its mechanical. Or have I misunderstood. How far are you away from CW , miles , as a matter of interest Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 22, 2007 Share Posted February 22, 2007 You must either plug the hose or refit the gauge to the hose. With no cats and an aftermarket exhaust you should be seeing around 1.0 to 1.2 bar boost without any boost controller fitted. If I were to look at it the first thing I would do is remove the boost controller hosing and return it to stock hosing. I was seeing about 1.0 to 1.1 bar and the fuelling was fine. I suspect a hose is off, split or something. I can have a look at it after the end of next week, if nothing is obvious. Quote Link to comment Share on other sites More sharing options...
Sheefa Posted February 22, 2007 Author Share Posted February 22, 2007 Thanks Mark. The boost gauge is a mechanical one mate and I never really look at it as it's tucked into the Glove compartment and I rely on the BC - stupidly! Cheer Chris for the response. Appreciate it. I'll refit the hose to the mechnical boost gauge tomorrow and take her on an early morning run to see if that sorts it. I thought I should certainly see more and I remember you saying everything looked good, hence thought this was a tad odd! Might need a trip down again then, hopefully not (no offence intended!) but if so, I'll give you a shout tomorrow. As Pete mentuioned, I'll be at Donington on Tuesday anyway, so perhaps if you do have a mo to check it out then, that would be great. All the experts in one place hey, fantastic, free labour too! Cheers Chris. Greg Quote Link to comment Share on other sites More sharing options...
Sheefa Posted February 22, 2007 Author Share Posted February 22, 2007 Bollocks to this. I'm taking her on a run now with the mechanical gauge fitted otherwise I won't sleep! Back in 20 to report back. Wish me luck! Quote Link to comment Share on other sites More sharing options...
Sheefa Posted February 22, 2007 Author Share Posted February 22, 2007 DAMN. I did have the Mechanical Boost Gauge hooked up, must of reattached the other night. Vaccum hose is on nice and tight, can't see any splits in the immediate vacinity. Also, it too reflects 0.76 bar or less as per my BC reading. Video is here: Apologies for the loud Glaxy music! On 0.74bar I was hitting 70mph over the 5,000rpm range too. Skip forward to the 50 second mark. http://www.youtube.com/watch?v=xkdbiCt0vwc My car is gay.

Sheefa Posted February 22, 2007 Author Share Posted February 22, 2007 Greg did you try it with thee BC off?? Ooops Quote Link to comment Share on other sites More sharing options...
terribleturner Posted February 22, 2007 Share Posted February 22, 2007 Im only saying it because i had a similar problem. My BC would peak at like 0.9bar, and when turned off would hit 1bar indicating there was a problem around the BC solenoid area. Quote Link to comment Share on other sites More sharing options...
Sheefa Posted February 22, 2007 Author Share Posted February 22, 2007 Thanks Terrible. I know mate, completely forgot to check. I'll do that tomorrow. Do I just switch it to 'OFF' , I don't need to unplug any hosing etc right? Quote Link to comment Share on other sites More sharing options...
imi Posted February 23, 2007 Share Posted February 23, 2007 just switch it off.... Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted February 23, 2007 Share Posted February 23, 2007 Remove the thing, pneumatically speaking, and plumb it as stock. then try it. Quote Link to comment Share on other sites More sharing options...
Sheefa Posted February 23, 2007 Author Share Posted February 23, 2007 That's a little too technical for me Chris! All those realsm of hosing, wiring and other gizmos behind the dash I'll bring her on Tuesday and if you can take a look mate for 5 mins or so that'd be great.

Sheefa Posted February 24, 2007 Author Share Posted February 24, 2007 Turned the BC off and same result. Not boosting above 0.76 bar. Quote Link to comment Share on other sites More sharing options...
terribleturner Posted February 24, 2007 Share Posted February 24, 2007 Hhmmm, worrying as i'd expect from your mods to be seeing 1bar or a tad under. I think you have a boost leak, maybe in the hoses too the BC as that obiously isn't working. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted February 25, 2007 Share Posted February 25, 2007 Turned the BC off and same result. Not boosting above 0.76 bar. If the boost controller solenoid isn't opening it will hold boost at wastegate level, which isn't enough to bring 2nd turbo on line. As I said before, remove the BC plunbing and put it all back to stock. Quote Link to comment Share on other sites More sharing options...

Sadly Chris, removing all BC plumbing and returning it to stock is not something I would be even mildy capable of doing, or even having a partial knowledge of where to start. I know, I suck!

Chris Wilson Posted February 26, 2007 Share Posted February 26, 2007 If i get a minute I'll have a quick look tomorrow, but I won't mess too much as you will want to get home in it, no doubt Quote Link to comment Share on other sites More sharing options...

Only if you have the time of course as I know the track day lasts.....well all day! It's not actually causing any 'problems', and she's running smoothly, but would be great to have this sorted! Thanks mate. Greg Quote Link to comment Share on other sites More sharing options...
