I agree ecuboost is the best in terms of features and control and once it is thoroughly debugged I will use it and save the avcr for a car with a less awesome ecu. I do however like being able to control boost without changing maps so a standalone ebc is very desirable to me. I am also using a 4port with my avcr to try and get it to have max range of boost levels and control. Different strokes for different folks!

 

that's some great numbers Tom. and congrats to the owner also.

 

400whp has been even achieved on 91 oct on a very well setup Evo on a proper Mustang dyno.

 

I made over 400whp on CBRD's mustang dyno @ 26psi...stock block, 93 oct....

 

I cant say i appreciate this comment to much..

let me explain something to you. you know the setting in v7 where it says WGDC=100% under this Load? I was hitting 536 load in my car and i set it to 350 load to hold the boost to 100% until 22psi. the car has a 25psi wga on it preloaded to 30psi..

so you would expect it to make it spool quicker right? since you're forcing it to hold 100% longer to get max spool.. well the higher i raised that number the worse the spool got. I ended up ending with it back about 270 load where it is making 15psi and that is where i got the best response. thats why i think something fishy is going on with the overall operation of this thing in the code. its simply not doing what you tell it to and boosted tuning explained it doesnt do this already 2 times now in this thread.

heres the settings i was using in my personal car;

**removed**

now are you gonna tell me its still the indian and not the arrow after what i said? or am i missing something here? should of brought the 100% wgdc in the map above to around 4k range? if it changes over to this table during the spool process then that could very well be a big possibility.. but does it is the question?

I am but im not, from experience on my car when i hooked up the mbc back on i gained lots of spool and more punch downlow... didnt notice anything different uptop though.

the ecu boost definitely craps all over the mbc as far technology goes and all its advanced features it has.. you can literally control the boost in the rpm's as you rev the car, its pretty crazy stuff.

Thanks for the kind words adam.. did you ever get a fmic? lol i still have the perrin here.

Thanks man lol. that comment made me laugh. Put some tokens in me and get an auto tune.

Yes we are testing with the new heavy spring

I agree and not denying its advanced and has many good options. id love for someone to do that test.

to everyone else thanks.. more testing to follow soon stay tuned.

 

I sent him my info yesterday but he never posted it...not sure why. All I got was a "the hallman killed it, I knew it would" response. I'm going to see if I can find both logs and post them up. I expect Tom to spend more time tweaking things on his car to make them the absolute best so when he's talking about tweaking load for max spool I'm pretty sure he hasn't done that for my personal car but I can't be sure. Give me a few and I'll post up the results that I got and I'll happily answer any questions re: does your ROM have this set, that set etc and look at it.

Here's the graph, the hallman actually peaked to 35.24 at 5450, the ecu boost peaked to 36.43 at 5990. I tried to keep them as close to identical as possible but obviously missed the boost a tad bit.

My hallman has the new "super spring" with the steel ball. I needed to hold more boost longer and the steel ball gave me the most bang for the buck to hold boost the longest. The ceramic was great but it gave up too much up top. I tested both ***** with the stiff spring, then both ***** with the super stiff spring (you have to call hallman and ask for this one, it hasn't been released yet).

 

I apologize

 

We aren't still talking BBK Full on 93 octane right?

 

Wouldn't the BBK owners be happy to see those numbers, haha.

No, we're talking about what the current topic is in this thread...ecu boost vs mbc and issues surrounding swapping back and forth. I'm posting this in here because that's the current topic of discussion and it is of benefit to everyone who is following it and wants to see the difference going from one to another regardless of turbo. My set-up is in my signature

 

tom im confused by this statement-

you just said "you can see in this test here spool wasnt really changed just the tq quite a bit due to more boost with the truboost.."

You would expect more torque, as boost makes torque power....

what was the problem that you simply didnt just run more boost on the 3port since the torque was the same?

It wasnt an apples to apples comparison as you didnt run exact boost pressures on the same setup-

insight?

(I do appreciate the discussion from all sides)

Anyway to get the best of both worlds ??

Im wondering if i should get rid of my GS until this is resolved but I dont think I should b/c of 2 reasons
1. Gear Based Boost
2. If I ever do Meth, I need it for map switching.

 

That's what tscomp and roadspike are working on

 

Ive seen the ecu boost beat much worse downlow, its not as bad on this car, thats why i said that. this will illustrate why its impossible for the ecu boost to do what the truboost did.





Notice the area highlighted? Notice how its spooling quicker? well it takes that momentum from that additional earlier spool and thats where the torque is coming from. It doesn't look like much on paper, but get in a car and test it for yourself.. its a very big difference in seat time (atleast it was in my car). and not on the dyno.. on the street.

ecu boost gives you a smooth transition with torque, where as other controllers hit more brutal and harder. I can see ecu boost being fine for stock blocks since its helping control torque and boost in general, but for a built engine ill never recommend it ever again.

If there's something anyone wants me to test on Chucks car let me know.. ill do more testing with the 3 port if you want it done, just pm me what you want me to do to it and ill do it.

We are not keeping the torque this high though. He wants it under 400tq.

But ya.. I can make the curve flat, go up, go down, etc.. theres lots of control with ecu boost.. if the spool can be corrected to work properly ill run it on my car, until then i refuse to lose low end response on a high dollar setup just because of a $100 boost controller.

 

First, when using a MBC, you still get the "boost cut" safety feature. Those other features dont matter that much, except for the map switching if you use two fuels alot.

Next, I have a LOT of experience with ECU boost. I wrote the how to's on it and have tuned many cars on it. I can say without a doubt, that a MBC spools faster and is more consistent.

 

Yeah- this argument is going in circles-

I disagree- and have seen the opposite here in testing-

and ecu boost offers things you simply cant- and for more than straight line drag or street driving-

throttle based boost (the best on a track car)
correction, multiple maps- etc...

we will have to agree to disagree

Cheers

thanks for helping a bbk client though.
