After some unfortunate circumstances i am back in the market for a ebc. I have greddy profec b's in the past on pretty much all my cars, and friends cars. I love the simplicity, price and overall functuality of the controller. The greddy is an awesome ebc, but i want an ebc with gear based boost selection. I know that apexi avc-r is the most mainstream ebc with gear based boost selection, but i have heard other companies offering this feature. I know that AEM is supposed to support the gear based boost control, but i run hondata and always will run hondata in my car for a number of reasons so switching over to the AEM is not an option. Anyone know of a gear based boost control other than the apexi?

 

The World acign one , but Chris wants a left nutt for it .
i showed you the pics before r5ight?
it has options for gear based, rpm based and something else.
its got a timer instaleld in it and some other **** , nice bling bling lsc display.

 

I figured there wasnt anything else out on the market. I am thinking of designing and making one for a school project. Would there be interest in something like this in the 200-250.00 price range with a warranty?

 

i am almost sure i heard of nhra trying to outlaw the use of "gear" based boost controllers....

can someone back this up or correct me? thanks

 

The controller would be focused on street driven cars, not track cars. Traction becomes the key issue to a fast turbo fwd, so by letting you get artifical traction control with the gear based boost controller you could put the maximum amount of power to the ground in each gear.

 

Innovative Turbo has one out (not officially). Called the MSBC-1. Just checked their site but it looks like there aren't any specs on there yet.

Found this link though: http://www.payntechnologies.com/products/inv_turbo.html

Doesn't the AVC-R have a gear-based boost setting? I could have sworn I read about it...just never hear anyone use it?

BTW, how would you do a gear-based boost controller? Use the clutch switch to act like a signal to the "controller" to switch the boost settings? And what about downshifting? How would the controller know if you downshifted or upshifted? Hmmm....

To tell which gear you are in you would need to tap into the speed sensor and rpm, similar to the apexi controller. Using a spread sheet in excel you can calculate which gear you are in if you have the proper gear ratios of the transmission. Its not as hard as it appears.

The apexi controller does have this function, but the controller IMO is complicated and on the expensive side. I'd like to introduce a controller at half the price, with gear based boost control that would be similar to the greddy profec in layout and simplicity.

 

Innovative is redoing their website so the full specs on their boost controller isn't up yet.

I do recall seeing a drag car with the ITS multistage ebc in it, but i can't remember where right now.

Edit : didn't see the website above, just go there.

Most of us only need a boost controller to do 3 things:

1. Consistently control boost levels no matter what the conditions. (no spiking).
2. Control boost according to gear/speed. you can manipulate either one to have the same effect. but i would prefer gear based.
3. Offer at least high/mid/low settings for street, track, and other so u don't have to re-tune the boost controller everytime u need to adjust it.

at least those are the main three 3 things I need/want. everything else is just a cool feature. It would be nice if there was something simple and to the point at an affordable price. bling bling does not make ur boost controller better no matter what mase says, aesthetics I could care less about as long as it works good.

 

now how would that work as far as retunign when you up the boost can you tune for your max psi you would want to run and tune it dead on like that and thne it will run rich when running the lower boost settings?

 

Watch out, I heard Mase will kick somebody's *** for saying stuff like that I agree though, I would love to have something like this. I was asking about it a few weeks ago but it seems like the AVC-R is the only thing out there.

BTW Chris...where do you get your avatars? I can never tell what the hell they are!

 

thats why u get hondata or standalone. then u can have the car tuned at every boost level. this is why afc/fmu is gay

 

i jacked this one from the appearance cosmetic forum. its a honda race driver.

 

i ahve a hondata . so that will recalibrate itself as far as fuel and timing at diff boost settings? i didnt think it could be capable of that

 

This is exactly my thinking with trying to make a gear based boost controller. The stepper motor has alot to do with the consistency of the boost levels, so I would have to use something similar to the profec b or apexi stepper motors. I am thinking that a devoted map sensor would help the controller in its accuracy of generating boost.

The layout would have a balance control ****, 5 ***** for boost control over each gear, boost spike adjusment ****, and street/track boost setting switch. I will have to use eprom chips for the gear ratios of each honda transmission, so included with the controller would be a chip that the user would have to change based upon the transmission that is being used. I have the features, layout and basic programming layed out. I need to work on the circuitry, and cost of the components. The two most expensive pieces are going to be the devoted map sensor and stepper motor.

Although the Apexi is out on the market, its a bit to complicated for what i want/need out of a boost controller. The one that is offered from innovative looks very promising, but i havent seen the cost and i guessing its going to be over 500.00. There is no other gear based boost controller on the market besides those two that i can find right now. I loved my greddy, but i always wanted specific boost for each gear. If i can combine the simplicty of the greddy, with the gear based feature I think i will have the ultimate fwd boost controller.

 

My roommate runs the Hondata and AVC-R on his 5G hatch that is mostly street driven. We had a hard time figuring out how to set it up til he called A'PEXi. They were very helpful.

 

Pete, the hondata interpolates between the values of fuel and timing in the maps. When we tune an area of say 9psi, its covered between the 7 and 11 psi tables in hondata. Hondata interpolates between the given values and gives an the averaged value for the timing and fuel for that specific boost level. Its basic, but works very well.

 

hmmm we might as well tune mine to higher boost then this weekend so i have the option
I should be getting the controller tommorow.Do you car if we install it quick when i get up there before we roll , it should only take 2 min at the most, i guess it just goes in line with the WG vac line ?

edit
and to play it on the safe side, will the boost cut help in case i get spikes with this controller.
like if i set the cut at 10.5 or whatever, if it does leak past 10 if we set it at 10, it will shut the boost down.
sorry to jack your post, but i was curius how this id goona work .

Yes the manual boost controllers go inline with the bottom wastegate port/line. It will take literally 5 minutes at most to install. I have tiny hose clamps if you need some.

 

well i sually use zip ties.
chek the rest of my post up top
is the top port only for EBCs and not MBC's

 

Correct, the top port is for ebc's only.

 

what about the blitz boost controller? i think it was like this, wasn't it?

 

As far as i know, which i could be wrong, the blitz does not offer gear based boost control. They offer rpm based boost control, which is something entirely different.

 

"if u build it they will come"- field of dreams

if u make it I will run it
