electronic vs manual boost c.

[alcali247]

i know electronic boost controllers are better than manual ones
but do yo guys think that its that much better. as in $50 for an
manual and $300 electronic.

Not really worth it IMHO. Although I do want one for ease of use(EBC). I would say the only real benefit of having an EBC would be like getting an AVC-R that you can adjust the boost levels for each gear, allowing more traction if you had a FWD car. The only other benefit is the scramble boost where you can alternate from two different boost levels, which there are some mbc's that will do that also. One nice thing though that a EBC will do that a MBC won't is if your car is overboosting due to boost creep or whatnot, it can help by lowering the boost levels automatically to try and keep the boost where you want it.

How about this new product then for the best of both worlds?

I can not believe you said that...manuals are pin-point-accurate,electronic ones most of the time are not,any one who goes wants to go fast most of the time go with manuals......mmm

I totally agree to a point, some MBC's I've had experience with wouldn't hold boost very well, but there are tons out there. And as for the electronic ones, I guess I should have clarified, certain ones will automatically kick down to hold boost (avc-r, profec A, hks).

And definitely, most of the race cars out there have MBCs on them.

Hi,

Why would a race car want to have a MBC and not a EBC. I thought that EBC were more accurate, and they also have the automatic kickdown feature to hold it at a certain boost level. Don't they. I'm new to DSM's.

first of all Im a MBC supporter..small...simple..effective

I don't know if i'm seeing this correctly...you are saying MBCs are accurate????

uh no.

they are not not by a long shot the spring in them is the weakest link. depending on weather conditions. the springs tension can change. It may not be dramatic but it can change.

EBCs are good for fwd and anyone who wants in car control from my expirence.

if you want low and hi boost Mark Hallman has a mod to be able to adjust boost from inside.

Ive had both the Greddy Profec B and Hallman MBC and both work fine. Ive had no problem setting my boost with either of them. The only thing that justifies the price of the EBC is being able to change your boost without pulling over and popping your hood.

I like Dejon Tools dual MBC. You have regular psi setting and another higher boost setting that you can switch between with a switch from inside the car. Thats what I am getting.

Just our of curiosity, y is the AVC-R known as a gear based EBC? I've had myine for over a year and never understaood that. The AVC-R does allow control of begining advance or retardation of solenoid duty per gear, but it's other wise set via RPM levels. Just thought I'ld ask.

 

[97GSXAT]

Another thing to mention that no one else has, is also the fact that with weather changes, the MBC will need to be readjusted due to this fact depending on where you live. Not a problem with an EBC

Although I do not have the AVC-R, I do have the AVC-D, APexi's answer to Greddy Profec B and EVC EZ, I guess. I did not know that it was "known" as a gear based EBC, but if so, it is probably due to the speed sensor function.

On the AVC-D, you can set boost as a function of increments above normal boost levels sat three RPM ranges, 3K, 5K, and 7K (i.e. +2, +4, etc but these do not necessarily correspond to lbs of boost per increment).

You also have the scramble boost function which allows you to increase or decrease the preset boost at the three RPM levels to a modified (+/-) amount across the board when you hit the scramble boost button. This will alter the preset boost by the amount you change on the scamble boost button for however many seconds you set on a dial in the back of the unit (0 to 30 sec).

Finally, there is a speed sensor function which allows you to increase or decrease the preset boost levels at the three rpm levels once your car hits a predetermined speed and higher. For example, if you set the speed at 60mph (about 100kph), the speed sensor function will alter (+/-) the boost to whatever amount you modified the preset boost level via the speed sensor button. I believe the speed is determined by the unit through the settings at the back of the unit which depends on the car you drive. So in this way, the boost controller does vary boost by gear (speed) since it calculates the boost by hitting a certain speed as calculated through the ECU's speed sensor (gear) calculation.

Hopefully this wasn't too confusing. This is how I understand teh unit to work. FWIW, I do not use the speed sensor function because it does not seem worth it, even for WWD like mine. I do like the scamble function though.

Well that was my attempt at explaining why I think they are regarded as gear based EBCs....

If you know otherwise, then please explain as I am neither too proud nor too egotistical to think that I have all the answers...

I see you are using the Greddy Emanage and have tons of mods, so if you know a different reason or are hinting that I misstated anything, please educate me.

Thanks.

wow im tempted to get that joe p one you linked to. its not too expensive... plus i am really tired of poppin the hood and changing the setting on my MBC. In AZ its nice and hott during the day.. 90-120, then when it gets dark it'll drop to like 50-60. I am sick of adjustin that dang thing and the temp really does affect it, that's why im getting an EBC sooner or later

Me612, Don't forget to tell JoeP to give me my referral cut.... j/k.
