Maaximuus Posted November 5, 2015 Share Posted November 5, 2015 Hi basically I've just got a blitz decat for my pretty much standard glanza, would installing the decat make it boost creep and boost cut like a bitch? If so what do I do to stop it? Thanks Quote Link to post Share on other sites
Whitenoize Posted November 5, 2015 Share Posted November 5, 2015 Possibly I found I hit fuel cut more when I removed the standard air box Quote Link to post Share on other sites

Maaximuus Posted November 5, 2015 Author Share Posted November 5, 2015 Get an adjustable actuator and run boost level below fuel cut Funny you should say that I've just bought a HKS actuator, now I've just gotta figure out how to use it Quote Link to post Share on other sites
Whitenoize Posted November 5, 2015 Share Posted November 5, 2015 You got a boost gauge ? Just adjust it ever so slightly until you get the desired boost level Quote Link to post Share on other sites

Whitenoize Posted November 5, 2015 Share Posted November 5, 2015 Not really mate wouldn't risk it best to get a boost gauge in to keep an eye on things Quote Link to post Share on other sites
Maaximuus Posted November 5, 2015 Author Share Posted November 5, 2015 Not really mate wouldn't risk it best to get a boost gauge in to keep an eye on things Yeah it's probably a wise investment, how much do they go for? Don't wanna spend much on gauges yet Quote Link to post Share on other sites
Ryan_EP82 GT Posted November 5, 2015 Share Posted November 5, 2015 Even a cheap one will do to set it below fuel cut. Jus entend the rod on the actuator and then slowly bring it in until yoi reach 11/12psi. If the actuator is new you shouldnt creep too bad.Plus i suppose if your taking your decat off to fit a blitz decat, why not port the wastegate out a little with a dremel. That way more wastegas gas can flow severely reducing creep. Quote Link to post Share on other sites
daniel_g Posted November 5, 2015 Share Posted November 5, 2015 Even doing all that shit i bet you my next wage you'll still get boost creep and hit fuel cut.When flooring it in the cold weather.CT9 turbos are very poor at controlling boost, the internal wastegate penny is too samll and even when ported out they are not that much better.Thats why so many people used to run FCDs because its the quick fix for not hitting fuel cut.

That way more wastegas gas can flow severely reducing creep.It's not a new actuator but I have got a speedvision manifold on the way so I imagine that will help and I won't have to port my stock mani. I've seen a few gauges for less than a tenner so I might just grab one to set it all up with!

Any ideas on what to do then? (on a limited budget by the way) Quote Link to post Share on other sites
daniel_g Posted November 5, 2015 Share Posted November 5, 2015 Personally id get an externally wastegate manifold and run a 0.6bar spring and you should never hit fuel cut. Then get an electronic boost controller when you can and dial in a bit more boost until the fuel cut limit.EWG setups control boost far better. Quote Link to post Share on other sites
Gainzy Posted November 5, 2015 Share Posted November 5, 2015 I'd buy a decent genuine boost gauge before anything I wouldn't touch the boost unless you have some sort of plug n play ecu or a piggy back especially this time of year. Save and gather parts put them all on at once imo do mani and decat actuator at once while there off I'd say a plug n play would do till next summer don't forget to buy genuine gaskets to Quote Link to post Share on other sites
StuDoc 72 Posted November 6, 2015 Share Posted November 6, 2015 Fitting an aftermarket mani as things are will increase boost creep not reduce it lol. Either fit an ext w/g or an adjustable actuator and port the int w/g. Failing that you could restrict your air filter. Quote Link to post Share on other sites

Christ all this for a decat lol fuck it I'm just gonna leave it, sounds like far too much hassle for a decat and expensive too Quote Link to post Share on other sites

Plenty research and you can't go wrong do it right do it once trust me haha Quote Link to post Share on other sites

Plenty research and you can't go wrong do it right do it once trust me haha Well I don't mind getting the wastegate ported as long as it's not too expensive and time consuming as my glanza is my daily (risky I know lol) but i don't know who will do it near me for a start :/ Quote Link to post Share on other sites

The beauty of a plug n play is adding other parts it works with them to a certain extent whilst a piggy back ecu everytime you change a part need another map.

Can't afford a plug and play right now anyway thanks for the link i'll have a looksie now Quote Link to post Share on other sites

Your scaring the fella.Dan ive never ever hit boost cut since i ported my wastegate and a new actuator believe it or not. Even in winter.I meant port the turbo wastegate not the manifold lol. Thats whatll reduce creep. But as said external wastegate is better for controlling boost Hands down, also dearer. If you just want a decat with no creep, port the wastegate for free with a dremel. Job done. Edited November 7, 2015 by Ryan_EP82 GT Quote Link to post Share on other sites
adzy Posted November 7, 2015 Share Posted November 7, 2015 If you've already bought an adjustable actuator just get a boost guage and then set it up so you don't hit fuel cut. What exhaust and air filter are you using? Do you have an fmic? Quote Link to post Share on other sites

Job done.Yeah I know you meant the turbo wastegate lol, I might give it a bash with a dremel but i'd probably need a full day to get the turbo off, get it done and all back together again, and that's if I think I can trust myself to not fuck it up haha If you've already bought an adjustable actuator just get a boost guage and then set it up so you don't hit fuel cut.What exhaust and air filter are you using? Do you have an fmic?I would do that but couldn't boost creep still put it past whatever I set it to and eventually up to fuel cut? Sorry for being such a noob I'm learning as I go I've got a standard exhaust, some random cone filter that was on the car when I bought it, but that's in the standard air box location (to the right of the engine) and no I don't have a fmic yet either :/ all in good time though Quote Link to post Share on other sites
