I still don't understand what a map sensor is... and do i need to have a v-tech engine for this setup to work? also with bigger injectors what is the stock size and what is a common size for boosted applications?

RE: twin turbo help - 4/29/2006 3:51:28 PM    marbro Posts: 1478 Joined: 1/16/2006 Status: offline The map sensor is right top of the throttle body. No you dont need vtech, and you wont find a turbo that is vtech only, but vtec in general is the reason turbo's dont spool up at lower rpm's and why you hear people complain about turbo lag on hondas, cause vtec kicks in and that larger lobe is spinning allowing more exhaust through which is why a t3/04 turbo usually kicks in at around 4000rpms. Vtech is usually set at 4250ish for stock, changing the ecu and having vtec kick in say at 3250 would help the turbo spool faster. If you just use a few pounds of boost (around 6psi) you wont need to change your injectors, but if you change your ecu upgrade your injectors too. Stock injectors are what, 250 cc? maybe a little bit less, not sure on that one. Keep in mind, this is just my opinion tho, its going to be the same route im going, when i upgrade my ecu im going to upgrade the injectors and fuel rail. (in reply to flomasta) Post #: 62

Looks good and it seems to get more fuel into the motor so I'm a happy camper, nevermind that it was way less than an AEM one. (in reply to flomasta) Post #: 64

There are also stand alone units which have the s100, s200 tags which i believe still use one or two of the plugs from the ecu to run everything (in reply to flomasta) Post #: 65

RE: twin turbo help - 5/3/2006 1:05:06 AM    marbro Posts: 1478 Joined: 1/16/2006 Status: offline Optional to a point. Recommended before that point because there are some things that you cant account for relying on the stock ecu. Plus it it makes the possibility of premature detonation extremely unlikely when youre running low boost. But as long as the system is setup right, its unlikely for that to happen. With the upgraded ecu installed your car will perform better on low boost because it will have better fuel maps then the stock system, and timing will be controlled properly on the ecu.

RE: twin turbo help - 5/3/2006 7:12:57 PM    marbro Posts: 1478 Joined: 1/16/2006 Status: offline i believe its ecu/engine specific, Most fuel maps will be defined based on max rpm and displacement of the engine, then different injector types will be defined because obviously the larger the injectors the more fuel that can be put in and the shorter the amount of time that the injector needs to be open, in turn the larger the displacement the more fuel and air that can be crammed in. But you will see at the hondata site the S series modules are for civics and preludes of certain ecu types, like mbo i believe said that he has a p06 and a full s200, downside is its probably got fuel maps defined for a h22 engine which runs a bit different from an f22. So, if you plan on changing your ecu, do research on the specific ecu's you might want to drop in your car, or find out if it would be better to just chip your current ecu.

RE: twin turbo help - 5/5/2006 5:44:31 PM    marbro Posts: 1478 Joined: 1/16/2006 Status: offline not really, but recommended, you want to give your turbo time to cool down, if your a person whos willing to sit there for a few minutes and let the car idle, then you dont need one, otherwise its something that keeps the engine running for a set amount of time based on how hard youve run the car, and is suppose to prevent the car being taken without the key, etc yada yada so, let your car idle a while every time and save some money ^_^ (in reply to flomasta) Post #: 71

RE: twin turbo help - 5/6/2006 8:27:32 AM    mbo1985 Posts: 778 Joined: 12/11/2005 From: Florida Status: offline They are cool though. I installed one in my car just a while ago and whenever I go to park my car and get out, lock it, and walk away with the keys in my hand, everyone looks at me like "dude, your car is still on." Just another way to turn heads I suppose while making sure your cooling that turbo down. (in reply to flomasta) Post #: 72

RE: twin turbo help - 5/6/2006 1:05:00 PM    flomasta   Posts: 123 Joined: 10/13/2005 Status: offline Thats pretty cool.... do most turbo apps. have boost controllers or are they self checked? (in reply to mbo1985) Post #: 73

RE: twin turbo help - 5/6/2006 6:55:45 PM    marbro Posts: 1478 Joined: 1/16/2006 Status: offline The purpose of a boost controller is to increase boost from the base external wastegate spring. IE: lets say you have a 7 psi spring in your wastegate, the boost controller will give you the ability to increase that 7 psi to that max capable for the turbo. Good if you have everything need to do that properly, bad if you dont have your engine build up and dont have high octane gas ^_- If you want a set psi that doesnt change, you dont need a boost controller, if you want to be able to change it, then get something like a 1 psi spring and setup your boost controller so you will offically have some gas economy when your running at higher rpms. A boost controller will not lower the boost below the naturally spring of the wastegate if you have 7psi and want less, the only way to lower it is to replace the spring.
