Cipan,

Plz give some advise. I planning to install MS1 on my 4G15 (mmc ecu) engine. When is it possible to meet up with u n get some advise ?

Regards

"With MS you can even control NOS activation, water injection, vtec, mivec, vvti,
vanos etc.."

Bro, are you sure for the vvti, because you need another table map for this.
Not vvti this time.....or may be vvt on Toyota Siver top/Black top.

You quote:
"To my experience with MS1, A/C still works fine without any of those controllers, unless with high cam or 4 throttle. Even those branded standalones too have no proper servo controls. What do you expect? You want the manufacturer to design a controller to coup with every type of servo?"

Bro, sorry to inform you, i have to correct this ( A/C ). For air cond loading, you do need a big air valve ( on top have a screw ) like, Toyota Levin 4AGE, Toyota Starlet,even a modern Toyota SEG 4AFE ( on top look like hex ), Toyota Silver Top....Nissan E15T, Nissan SR-20...Honda VTEC ( behind the intake manifore )....

So, when A/C turn on/cut in, the engine rpm will drop at least 500 rpm. In order to maintain idle rpm ( say at 1000 rpm ), the the air valve will swith on and bypass more air to the engine in order to maintain idle ( off couse , fuel have to add also, or you can use map loading ).

Off couse, there are two ways to do. Simple connect the air valve wires on the A/C clutch or connect to the ECU ( which is support )

For Mitsubishi, you have to use stepper motor or servo ( off couse, you can mod and use big air valve )

Nows aday, if you see carefully, modern engine to need a air valve and modern engine like Campro,"drive by wire" ....i mean too advance...we can forget about it...just mod the throttle body with "foot cable"

Ah.....one thing....please do not use the "normal" air valve which the hole too small for the A/C to maintain the idle ( may be it can up to only 50 ~ 100 rpm )

If i am wrong, please do correct me. After all, we just try to help...and you know, thats why eraser always on top of the pencil...he...he...he

Good Luck.

leftfoot, u already done what in my mind.. 4 throttle and mivec so jealous le.. it should be a lot faster than my 4g93p ma.. but i'm not gonna do it 1 shot. i plan to use ms to play with my 4g93p 1st.. hehe

i know that modify anything in ur car will involve money. i also understand the teory of no free lunch.. but i see the point of i'll gain some knowledge from there using ms and it is interesting since it is still improving.. this is the reason y we all here also rite?

i never ask anyone here to to MS in 1 day time la.. come on rushing always no good work and every1 knows it.. i rather do it slowly 1 by 1.. patient is the word

asking question 7 cos i wanna know more about ms ma.. dun blame me for asking bro.. newbie ma still studying ms atm.

cipan, thanks for explaination for the ALS. very simple, if wan something then prepare to lose something. cheers~

Good Luck.

Yes, you are wrong.
You can activate 2 tables to use for those purposes with MS. Please do a further research before making negative comments and don't mention that I don't know the difference between vtec and i-vtec, vvt and vvti. These system are quite new in the market and for people to wreck up their cars just for the sake of r&d have a very small potential. Research is still going on to perfect the implementation of vvti controls. Due to it's diy concept, you actually can controls various applications using MS. It's really up to you to explore and make use o what function you do need. If you're good in coding, make up your own codes to make your application usable with it. There are lots of ways and means to use MS.
MS2 have the feature for servo controls. If you insist on using those, then you have to buy the MS2. For ease of installation, (it's DIY) it's better to use those air bleed system for A/C which I recommend. It's easier and cheaper option. If you are not comfort with a little sagging in rpm and if you want total comfort, use oem ecu.
Controlling rpm when activating A/C is not a big deal. Furthermore you're after performance, not leisure anymore, and that is something that can't be done with the oem ecu. I think I've quoted many times before, oem ecu is the best for normal usage. The manufacturer runs hours of testing and tuning parameters before settling down on one map that's best for their product in many terms. What do you expect from a stand alone ecu that are been finalised from start to end in just a couple of days? Tuning done on dyno for couple of hours?
Think again.

p.s; "I got no credit for supporting MS here. I'm not the dealer nor distributor but I know I can help those who wants something CHEAPER AND AFFORDABLE for their upgrade and make their 'dream' to use a standalone as their tuning aid comes true." At least we now have more option of standalone to choose. Which product you're favour of.... it's your choice. Not even one product are built for inferior quality.

cipan_supercas,
You quote:

Bro, from the megatune software, what i know is fuel table, ignition table, volumematic eff. table and A/F table. So, where to find the vvti table to edit and how to tune it.

Well, for the A/C control ( you need a big valve ), that you have to let MS users to answer it.

"The Truth Is Out There".....he....he....he

Good Luck.

p.s. I ONLY get a small credit in this thread and not the MS also.
Anyway, we try to help those people whose use MS and some others stand alone unit. We just give a hand for some general knowledge....

 

[cipan_supercas]

Study the software further... with a little mod, you can even activate 4 tables. What do you want to use the tables for? up to you. You can use various switches to activate it, be it MAP sensor, rpm, throttle position, temperature, etc. When I say 4 tables, I mean four sets of VE and Ignition tables.
However, 1 is more than enough to run most engine type, but the provision are there should you want it. Up to your imagination of how to implement those extras.

actually, to me, megasquirt is not a DIY ecu. its DBC (done by cipan) hehehehe

Hi guys!

I m pretty confuse on how the MS is going to control the VVTI proportionly?

I dont see how you are going to control the VVTI system with the 4 VE Mapping table.

What you are doing is disabling the VVTI system and run it with VVT. VVT has 2 function which is on/off or in another word is full retard and full advance.

VVTI function works from full retard to advance proportionly and retard proportionly.

In order to control VVTI you will a 3D map which based on PID. Plus the ecu must be able to control close loop even in full load.

Hey ppl,
Just to share, my car running on MS also.
Done by Cipan too...
Been driving it for almost a week.....everything seems great! :)
Idling could be a little rich, but can be settle.....
:)

No time to mess with it yet. Work has been a killer and been reaching home late night everyday.....
Hope to have some time later
:)

would really like to see ur ride
i'm using b6t too
been lurking this thread for quite a while
planning to use MS too

cipan,
will contact u once my financial is ready

 

[ecupro]

To all,

Emmmm....down for so many days.....seem to be lost a lot of "talk".....

Where is Cipan "talk", ecupro "talk".....he...he....he

Or. remove by Joker...he...he.....he

Anyway, where is everybody, i ment.....MS user....

 

[ecupro]

Oh...oh...,
I see, I must open my big eyes...Tom give a message to all...due to technical error....

Sorry, Joeker,please forgive me.....

Hello, Cipan, how is every thing ? go for holiday!

 

[Joeker]

Dear ECUPRO,

Forgive wat? I dunno wat you talking about.

ANyway, please let us know when you are free to come KL to demonstrate your DIY homemade standalone programmable ECU PROTEC.

THanks.

Yeah! Hehehehe !

 

[cipan_supercas]

ecupro;
Got many things to do. Just back from NZ and S'pore. Now waiting for a friend from Penang. Luckily, he is coming down here. If not, I have to travel again. Very tiring and boring.

 

[kennethfong]

yo guys!!

thanks to cipan, i've finally set up megasquirt in my car n it's running great, extremely smooth and powerful at the same time, just i thought i might be running difficult air cond idling or normal idling, but i dun seem to have that problem, everything is satisfactorily acceptable!!!

hope u guys could consider installing this as it's the cheapest standalone available!!
