this is getting ridiculous. hahahaha I just upgraded my SMC to SMC+ like a month ago. And know there is another upgrade! damn....

How much? :D Im installing the turbo kit in april. I need my fuel management by then.

 

Yes, count me interested in the SMC500!

 

Need the info... how much to upgrade from a standard SMC?

 

and how much to upgrade from the smc+ to the smc500? i'd be interested.

 

i was told 30+shipping.

 

ttt

 

The SMC500 has been released and the website will be updated this weekend.




Another SMC to be released is the SMC Dual. The SMC Dual has the same rpm intervals as the SMC500 but it also allows for different fuel profiles at a user set psi level (adjustable from 1-9psi). For example, if you have 5000 rpm set at -35% fuel correction for 1-7psi of boost, but you want -30% at 8psi and up, then you would program the SMC Dual to switch fueling at 8psi for better fuel delivery at higher boost levels.

 

how do you go between the 2 settings on the dual? why only up to 9psi? and how much to upgrade to the dual?

 

You can switch profiles from 1-9psi but the SMC dual will still deliver fuel up to your OEM MAP psi limit. The SMC dual allows setups to boost more than the OEM MAP psi limit without necessitating for a 3bar MAP sensor, since you have the advantage of changing fuel mapping profiles past 9psi.

Conversely, you can also use the SMC dual to save fuel. If your FI setup is too rich off-boost, you can have the SMC dual switch MAP profiles after 1psi. With this method you can have the engine run leaner under low loads for better gas mileage, but run full rich under boost for maximum power.

Your killing me...

So, there seems to be a general interest in a unit incorperating a BTM... any near future plans? Lets see, a SMC Dual BTM... has a nice ring to it. Don't you think?


If you kept your pricing this low, I bet you would corner the market for aftermarket "street boosted" cars. All one would need for a street application would be the SMC Dual BTM, the proper sized injectors, and an hour or so of dyno time. Hell of a deal when you look at the "big picture".

hey zip...

how much is the smc 500 and the smc 500 dual?

i need to buy either the 500 or the dual asap (depending on cost.)
Also, i seem to be a little confused about what exactly thedual does. Correct me if im wrong: basically its 2 settings that you can switch between based off of boos?

thanks,

This IM message should clear things up about the SMC Dual:


(12:47 AM 3/21/2003) zip: What do you want to know about the SMC dual?

(12:49 AM 3/21/2003) blufke: alright. well i know the + and original smc will cut fuel proportionally from how you have it set when you are not boosting, so how is that different than the dual?

(1:00 AM 3/21/2003) zip: The SMC Dual will allow richer settings past a preset psi point you set from 1-9psi. For example, say you have to richen 5K rpm at -35% to accomodate for boost with an AF ratio of 12.0:1, but that correction setting may run rich at part throttle. Increasing the correction to -40% will help lean part-throttle, but say your AF will go up at full boost to 12.5:1 with the new correction.
The SMC dual will eliminate this situation since you can set no boost situations at 5K to -40% and have it change to -35% past 1psi, or greater, of boost.

You can also use the SMC Dual to provide more fuel at higher boost levels. For example, at 5K rpms at about 9psi your AF is 12.0:1, but when you increase boost to 12psi the AF goes up to 13.0:1

The SMC dual will allow you to richen the 12psi of boost by having it switch correction past 9psi of boost. The SMC dual was developed exactly for this case. It will allow the user to have TWO fuel maps at different boost levels for the optimum AF ratio.


(1:04 AM 3/21/2003) blufke: but doesnt the regular,+, and 500 do that? i thought it cut the fuel proportionally for off boost driving. i understand that it is an advantage for the higher boost level, but lets say that i only run at .45 bar and partial throttle(regular driving), isnt the dual just like the regular,+, or 500 but i now have to set the fuel point for off boost driving?


(1:07 AM 3/21/2003) zip: Yes, the SMC, SMCplus, SMC500 all function linearly. Some FI setups do not have that linear function as previously described with the different boost setting example.

(1:11 AM 3/21/2003) blufke: but with just one boost setting, say .45 bar. why would i want to choose the dual? i guess i would be able to really adjust the off boost fuel to a nice desirable setting. oh, and also, how much to upgrade to the dual? and the turnaround now?

(1:17 AM 3/21/2003) zip: We haven't determined the upgrade pricing for the SMC Dual, but it should be around ~$40. In your case, you may not want to use the SMC Dual, which is why we offer the SMCplus, SMC500, and SMC Dual to accomodate different setups and budgets.

(1:24 AM 3/21/2003) blufke: i will get a boost controller fairly soon so i probably will want the dual, but does the dual cut fuel linearly too when you are at no boost setting? i mean say tuned at .45 bar and .75 bar. how will it do at off boost?

(1:45 AM 3/21/2003) zip: It depends where you want the dual to engage. The SMC dual will only switch fuel settings anywhere from 1-9psi. Off-boost and boost linearity will remain the same until the motor hits the particular boost setting you want to change the fuel mapping profile.

(1:52 AM 3/21/2003) blufke: so the dual still has linearity while also having two fuel settings that switch over at a certain psi. so lets say i have a setting for a certain fuel up until 7psi. it will cut fuel linearly when not boosting/partial from the 7psi setting and when at full throttle until 7psi be at that particular setting and anything over 7psi be at the other setting. and how does the smc know what psi to be set at, and which whether or not you are adjusting for over that psi or under it.

(1:56 AM 3/21/2003) zip: Yes, you are correct the SMC dual will have linearity from vac to your 7psi setting. Then it will jump to whatever settings you have set past 7psi. Think of it as two linear lines. If you have settings past 7psi with the same amount of correction then it will function like any other SMC.

(1:59 AM 3/21/2003) blufke: and how does the smc know which setting you are adjusting for, and how do you select the switch psi? and the switch point is adjustable up to 9psi?

(2:08 AM 3/21/2003) zip: Yes, the SMC dual map switch over is adjustable from 1-9psi as previously stated. The right most turn screw doubles as a correction and fuel map switch over point.

 

that was a personal IM zip! i didnt give you permission to post that. *sniffle* *sniffle*


in case you couldnt tell =>

 

but why couldn't i just tune the fuel curve to 10psi, then run 6 and when i want to switch to 10, it'll be right back there?

bah... i think all i need is the smc+

how much zip? i wanna buy one asap
