2 bar! I nearly had a fit!!


Recommended Posts

Just installed a greddy electronic boost controller today, its very nackerdooky! Was having a spirited drive along the A2 towards Dover, I thought to myself lets have a wee blast and see whats whats, sank the boot and off we went, I thought, "My, isnt she going well!" until I glances at the controller and saw my boost getting very close to 2 bar!! I nearly keeched my tweeds!! Upon reading the manual properly it would appear that I had wiped the facory setting of 0.5 bar and given it a ridiculous limit. Dont seem to have damaged anything but it was a bit of a shock, knocklink didnt christmas tree though which was peculiar. Im never going to "Plug and play" again without reading the manual properly!

Got it sussed, I have resricted peak boost to 1.1 bar which Im mapped for, I can make it spool early or late, crank it up or turn it back, will allow me to map for 1.4 bar and run that boost with my standard map sensor, a 3 bar map sensor would have taken away one of my rows in the link map which would have been pants. Also, with the 3 port boost solinoid gone and better pipes and the plastic restrictor gone, things are far more exciting, Ill have to fiddle with it for a while but once I get the hang of it and get it set up, I recon she will be much quicker than her current rapid self, even with the current map profile. Andy thank you for the Japanese Philosophy, I have also head

"Wise man wif gucci boost controller, is easily a fool with blown engine." So Im going to Caw canny until im up to speed with the thing!

Well, I was out today and I got the controller set up reasonably well. And I can definately say that the car is much quicker with the same level of boost, it is spooling the way a modified car should and the horrible lag that I thought was the price I paid for a FMIC is much less. Dont know if this is because the waste gate is staying closed longer and opening quicker, or because the pipes are a better quality, shorter and not restricted. On the down side she needs a remap badly because the knocklink is sparkling like liz Hurleys engagement ring

under hard acceleration, and if you listen you can hear what sounds like ballbearing being bounced rapidly off the block, which is the dreaded det, not bad, but in fighter pilot mode its definatly there, so Ive set the low boost setting at 0.8 bar and no megga spool up, and am going to use that until I get mapped. I even resisted the temptation to chase a motorbike!! I am chuffed face-icon-small-smile.gif

Safe is good, these people who have huge power have the facilities to rebuild and the knowhow etc, people like us need to watch what we are doing because its an expensive mistake to run too much boost if your internals arent uprated and your fuel etc isnt mapped for it.

Grovit, no my car is a 95 STI RA and the bottom end is a new sti 7 one with a semi closed deck block and slightly different rods and pistons than the classic sti ones. The man who built it told me not to run anymore than 1.4 bar boost, although stronger its still a standard set up. I would be a fool to disregard his advice. If you are going to uprate your car, you must keep it within the bounderies dictated by the internals of your car or its life will be short lived. There are people on here and other sights whose knowledge is far greater than mine, my advice to you would be to do some digging, find out the safe working limits of modification your car would take and work within them, if your not happy, dont do it until you have all the facts. The net is full of hard luck stories brought about not by stupidity but by people uprating cars and not knowing the whole story, which leads to an early retirement of thier engine, yes do it, but do it safely and always look at how old the engine is and how many miles you have. Good luck!

Cheers Callum !!

Yep - don't worry - I'll be researching my ass off before I start fiddling about with the engine - as you say there are many, many stories out there of blown engines and emptied wallets. Even before I tackle the heart of the beast, I'll be upgrading to 4 pots to make sure I can stop !!

Was just curious to see what your one was, sounds like a hell of a machine - will no doubt have a gander at it at some point this year (runs / meets etc)

Would be happy to take you for spin one day, Its a bit of a beastie! But Im sure there are others who are far more modified than mine.

Its How you drive it that counts. I gave Dougster a shot of her when I had finished my upgrades and had to stop him halfway because he was scareing me!! And thats the truth!!
