How to increase boost?

Can the boost be adjusted through the ECU?

I normally use a mbc but after some searching everyone frowns upon them so I was curious just how you do it? I'm tuning myself with enginuity and ecu flash .

theres nothing wrong with mbc or ebcs....i dont know who you've been talking to. I run the greddy pro spec ebc and its just fine. Turning the boost up without tuning won't be good for your car no matter how you do it...maybe thats why they frown on them? Id acually vouche for a boost controller if you upgrade your turbo...stock solenoid sucks.

Partially right. An MBC sucks, there were too many stories of 02's blowing their engines and turbo's from these things. An EBC with a protune will work just fine and is a good setup.

you guys are giving answers to a question he did not ask

1) Raising the boost WITHOUT re-tuning (dealing with the ECU) is ALWAYS bad, no matter what kind of boost controller you use (MBC, EBC, whatever).

2) Yes, you can adjust the boost simply through re-flashing the ECU. This is the BEST way to do it because it's easy to adjust other parameters while you're in there as well to compensate.

3) IF IF IF you already have a means of tuning and want to replace the stock solenoid, than an EBC can do wonders at helping you maintain a more consistent boost. This of course requires you already have tuned the thing to use it.

The fist engine mod you do is the ECU and every other engine mod you do should be accompanied by ECU adjustments as need AS WELL.

Thats what I was looking for, I'm installing my wideband soon and haven't messed with changine maps or anything But I have been doing alot of reading and I'm sure if I can handle a honda with chrome I can handle this ... I didn't know if the boost was adjustable though the ecu map but it looks like it is . Awesome thanks guys

a MBC WITHOUT tuning is a bad idea. An EBC with tuning would help your issue, yes.

However, some change in performance due to altitude is EXPECTED and A GOOD THING. One of the strengths of letting the ECU handle boost control rather than doing it manually is the car can dynamically adjust for things like altitude changes.

Will you make more power at substantially lower altitudes? Hell ####ing yes. You can't change the laws of thermodynamics with a MBC either you know. Denser air = more power.

Honestly if you have a laptop you can get a tactrix cable and a pre made tune cheaper than a lot of ebc. That will fix your boost and your tune all for about 140.00 including the cable which can be reused.

I've got the cable and the software

Can I make my own maps ? Or can I only flash the ECU myself?

With the right software you can edit and flash maps. I recommend reading a rediculous amount before you even attempt editing. Hve you read the opensource stickies?

Yes, I have read the stickes. I have read alot and I know how to flash maps by memory now but I'm not quite sure how to edit my maps . I'd like to go save my current map, get a datalog with it then see what ya'll think then bump up the boost and re log and see where I need to adjust . Am I on the right track here ?

It's not that simple bro...like "bumping up boost".

Ign anf fuel also need to be adjusted to ensure no detonation.

Aren't there any free OTS maps you can try (someone can make an input here).

If you think you've read enough you haven't. You need to tune fuel first, then timing, and lastly boost. Can't just crank up the boost than make everything else play catch up.
