Guest jimbo123 Posted March 1, 2005 Share Posted March 1, 2005 Hi i have recently decatted my exhaust and wondered what is the best for money boost controller and how easy are they to fit???? I LOVE SUPRAS Quote Link to comment Share on other sites More sharing options...
Jake Posted March 1, 2005 Share Posted March 1, 2005 They're pretty easy to fit. I fitted my GReddy E-01 in less than an hour and that was taking it easy. Which is the best value for money is a difficult question to answer. The E-01 is certainly one of the very best ones but it ain't cheap at approx £300 Quote Link to comment Share on other sites More sharing options...
TLicense Posted March 1, 2005 Share Posted March 1, 2005 I have the Blitz SBC id III and to be totally honest, I'm dissapointed with it. I can't get it to hold a particular boost. Even in the setting where you can select a boost level, I couldn't get it to keep a constant boost. It seems as if weather (air temp) effects it massively. I'm sure I've heard people say that they can get it to work, but I'm always over boosting, and having to lift off to some degree, or not making the boost that I want when flat out. Quite expensive too if bought from certain retailers. I bought mine in combination with the powermeter from Japan (takakaira.com) and saved myself over £200.

hadyn Posted March 1, 2005 Share Posted March 1, 2005 if you just want a constant level of boost without switching between high and low levels of boost, isnt a restrictor ring the best boost controller?? And considerably cheaper too? Quote Link to comment Share on other sites More sharing options...
SimonB Posted March 1, 2005 Share Posted March 1, 2005 That depends, with a restrictor only you will get quite big differences in boost depending on the temperature etc. Also the boost will build more gradually - with a decent boost controller you can bring max boost in earlier. The E01 has a facility to set the max boost you want, then when you reach it it will reduce the duty cycle of the boost solenoid to keep boost below that level. You can also vary boost by RPM, although I'm not sure why you would. There is one controller that lets you vary things by what gear you are in, which would be good because you get more boost in higher gears so need less assistance from the controller.

Homer Posted March 1, 2005 Share Posted March 1, 2005 Am I correct in thinking that with a boost controller fitted (e-01 for example) you don't need a restrictor ring? i.e. the boost controller can keep the boost below a set level on its own?

No, you can't lower it below the normal boost of the engine. All a controller does is bleed off pressure to make the wastegate open at a higher than normal boost. E.g. say normally the wastegate opens at 1BAR. The wastegate can't flow enough air out the way with a decatted car, so boost builds to 1.3BAR say. All a boost controller can do is delay the wastegate opening. It can't change the fact that the wastegate can't flow enough air. What you can do though is use a restrictor ring to hold boost at 1BAR say, and then use the controller to set what level of boost above that you want.

Homer Posted March 1, 2005 Share Posted March 1, 2005 Thanks for clearing that up Simon. Looks like I need to invest in a new restrictor ring first as I'm hitting the TRL fuel cut all the time now (damn cold weather! ) Quote Link to comment Share on other sites More sharing options...
Soonto_HAS_soop Posted March 1, 2005 Share Posted March 1, 2005 I've got the E-01, and although it only took me 15 minutes to install (I was removing an SBC), the thing that took me 6 months to sort was the fitting of the screen. Finally got it installed into the glovebox 2 weeks ago. I liked the SBCs looks, but the screen is far too small to see easily. The E-01 is soo much easier to see.

heckler Posted March 1, 2005 Share Posted March 1, 2005 I have the SBC ID 3 - holds boost no probs.... what ever i set it at... Quote Link to comment Share on other sites More sharing options...
Homer Posted March 1, 2005 Share Posted March 1, 2005 What boost are you hitting? Not sure mate, boost gauge is broken!! I think its at bit above 1.2bar, someone here told me the TRL fuel cut happens at 1.25 bar, I hope thats correct! Quote Link to comment Share on other sites More sharing options...
Getrag Posted March 1, 2005 Share Posted March 1, 2005 What you can do though is use a restrictor ring to hold boost at 1BAR say, and then use the controller to set what level of boost above that you want. Noob question: If the restrictor ring is limiting boost to say 1BAR, how can the BC then raise it above that? Anyone got a definite level on when the TRL cuts boost?

Anyone got a definite level on when the TRL cuts boost? The ring is just used to limit the standard flow of thexhaust, a boost controller can increase the flow over the standard rate, with the downside of extra heat.

Homer Posted March 1, 2005 Share Posted March 1, 2005 Did a search, TRL fuel cut happens at 1.25 bar: http://www.mkivsupra.net/vbb/showthread.php?t=27530&highlight=trl+fuel+cut Quote Link to comment Share on other sites More sharing options...
Getrag Posted March 1, 2005 Share Posted March 1, 2005 Thanks...will have to read up about how BC's work. Thats reasuring about the TRL. I've only had boost cut once since fitting it...and that was cold temps. Quote Link to comment Share on other sites More sharing options...
Homer Posted March 1, 2005 Share Posted March 1, 2005 Seeing as this thread has been totally hijacked (sorry Jimbo!), may as well use it to ask another question Is the E-01 suitable to use as a boost gauge? I've seen LCD screens on boost controllers before but they just seemed too slow to refresh and difficult to read to get a decent instantaneous reading from, is the E-01 any better?

Jake Posted March 1, 2005 Share Posted March 1, 2005 The E-01 is a very good boost gauge. If you use it in graph mode, you can see the last 30 seconds of boost (or something like that) Easy to read too. Quote Link to comment Share on other sites More sharing options...

I've seen LCD screens on boost controllers before but they just seemed too slow to refresh and difficult to read to get a decent instantaneous reading from, is the E-01 any better? You can use the E-01 as a gauge, but I much prefer a dial gauge than an lcd, as it doesn't have that "grey" area and is much easier to see immediately. Hence why I also have a Blitz TTimer with vacuum fed gauge, and a HKS dial with electrical input. Quote Link to comment Share on other sites More sharing options...

IMHO I prefer the HKS dial gauge. My E-01 is located in the glovebox though and only comes out to impress people. Quote Link to comment Share on other sites More sharing options...

That's odd, I'm the other way around. I had both types of gauge in my RZ but I never looked at my dial gauge once I got used to the e-01. I like that you can look at the gauge 10 secs after you hit peak and clearly see what boost you just hit.

No wonder you didn't get used to the e-01 if it's in your glovebox ! Quote Link to comment Share on other sites More sharing options...

It spent 5 1/2 months hidden behind the passanger seat mate!! LOL!!! I think it's down to this and the fact the HKS gauge is right in my face in a pillar pod that I think that it's easier to see. I just see the E-01 as jumping large "blocks" whereas the needle just seems to flow smoothly, IYSWIM. Quote Link to comment Share on other sites More sharing options...
Homer Posted March 1, 2005 Share Posted March 1, 2005 Thanks fellas Must admit I did like being able to see the instant reading of my HKS gauge! Wish I hadn't sold my spare Greddy gauge now, espcially as I have an e-manage ready to go in too! Quote Link to comment Share on other sites More sharing options...
Jake Posted March 1, 2005 Share Posted March 1, 2005 If you've got (or are thinking of getting an e-manage in the future) then the e-01 is a no-brainer You know the e-01 can be used to display e-manage info and to program it, right? Quote Link to comment Share on other sites More sharing options...
